A Critical Analysis Of The

A Critical Analysis Of TheThis essay leave present a reflective account of talk sk balefuls in practice whist under victorious judicial decision and news report taking of two intensifier Cargon endurings with a similar condition. It all(a)ow for endeavour to seek all told aspects of non communicative and communicative communicating styles and reflect upon these argonas using Gibbs reflective cycle (1988).Scenario A Mrs pile, 34, a passenger in a road traffic collision who was not wearing a seatbelt was impel through the windscreen resolveing in multiple facial nerve wounds with extensive facial swelling which carryd her to be intubated and sedated. She soon has cervical spine immobilisation and is awaiting a secondary trauma CT. Mr James was also compound in the accident.Scenario B Mr James, 37, husband of Mrs James, the driver of the car, was wearing his seat belt. He had minor superficial facial wounds, fractured ribs and a fractured right arm. He is alert and or ientated but currently dyspneal and requiring high group O concentrations.Patients who atomic number 18 admitted to Intensive rush atomic number 18 typically admitted due to serious seedy health or trauma that may also ask a say-so to develop manners threatening complications (Udwadia, 2005). These uncomplainings are commonly unconscious(p), have limited movement and have sensation deprivation due to sedation and/or disease processes. These critical conditions rely upon modern technical support and invasive procedures for the purpose of monitoring and enactment of physiologic functions. Having the ability to impellingly communicate with patients, colleagues and their close relatives is a radical clinical skill in Intensive care and central to a skilful nursing practice. Communication in Intensive Care is so of high importance (Elliot, 1999) to provide information and support to the critically ill patient in order to reduce their anxieties, stresses and preserve sel f identity, self esteem and reduce social isolation (Joo 2009, Alasad 2004, Newmarch2006). Effective parley is the key to the collection of patient information, delivering quality of wish and ensuring patient safety.Gaining a patients history is one of the most important skills in medicine and is a foundation for both the diagnosis and patient clinician tattleship, and is increasingly universe undertaken by nurses (Crumbie, 2006). Commonly a patient may be critically ill and therefore the ability to perform a timely assessment whilst being prepared to administer life saving treatment is crucial (Carr, 2005). Often the patient is transferred from a ward or department indoors the hospital where a comprehensive history has been taken with documentation of a full examination investigations, functional diagnosis and the appropriate treatment taken. However, the patients history may not have been collected on this main course if it was not appropriate to do so. Where available pat ients medical notes potty provide essential information.In relation to the scenarios where the patient is breathless or the patient had a reduced conscious level and requires sedation and intubation, effective communication is restricted and obtaining a comprehensive history would be inappropriate and almost certainly unsafe. The breast feeding Midwifery Council promotes the importance of keeping clear and accurate records within the Code Standards of Conduct, performance and ethics for nurses and midwives (NMC, 2008). indeed if taking a patients history is unsafe to do so, this required to be documented.Breathing is a fundamental life process that usually occurs without conscious thought and, for the healthy person is taken for granted (Booker, 2004). In Scenario A, Mrs Jamess arrived on Intensive care and was intubated following her facial wounds and localised swelling. Facial trauma by its self is not a life threatening injury, although it has often been accompanied with other injuries such as traumatic brain injury and complications such as air authority obstruction. This may have been ca practised by further swelling, eject or bone structure damage (Parks, 2003). Without an artificial airway and ventilatory support Mrs James would have struggled to breathe adequately and the potential to become in respiratory arrest. at bottom scenario B, Mr James had suffered multiple rib fractures causing difficulty in expansion of his lungs. Fractured ribs are amongst the most frequent of injuries sustained to the chest, accounting for everyplace half of the thoracic injuries from non-penetrating trauma (Middleton, 2003). When ribs are fractured due to the nature and site of the injury there is potential for underlying organ contusions and damage. The consequence of having a flail chest is pain. Painful expansion of the chest would result in inadequate ventilation of the lungs resulting in hypoxia and retention of secretions and the inability to communicate effi caciously. These combined increase the bump of the patient developing a chest infection and possible respiratory failure and potential to require intubation (Middleton, 2003).The key issue of Intensive Care is to provide patients and relatives with effective communication at all times to ensure that a holistic nursing approach is achieved.Intensive care nurses care for patients predominantly with respiratory failure and over the years have taken on an extended role. They are evaluate to examine a patient and interpret their findings and results (Booker, 2004). In these situations patient requires supportive treatments as soon as possible. Intensive Care nurse should have the ability and competence to carry out a fleshly assessment and collect the patients history in a systemic, professional and sensitive approach. Effective communication skills are one of the many essential skills involved in this role.As an Intensive Care nurse, introducing yourself to the patient as soon as po ssible would be the first step in the history and assessment taking process (Outlined in Appendix A). Whilst introducing yourself there is also the aim to gaining consent for the assessment where possible, in conformism with the Nursing and Midwifery Councils Code of Professional Conduct (NMC, 2008). Conducting a comprehensive clinical history is usually to a greater extent helpful in fashioning a provisional diagnosis than the physical examination (Ford, 2005). Within Intensive Care the Airway, Breathing, Circulation, Disability, Exposure/Examination (ABCDE) assessment process is widely used. It is essential for survival that the type O is delivered to blood cells and the oxygen hatfulnot reach the lungs without a patent airway. With poor circulation, oxygen does not get transported external from the lungs to the cells (Carr, 2005). The ABCDE approach is a simple approach that all team members use and allows for rapid assessment, continuity of care and the reduction of errors.C ommunication reflects our social world and helps us to construct it (Weinmann Giles et al 1988). Communication of information, cores, opinions, speech and thoughts are transferred by different forms. Basic communication is achieved by speaking, sign language, body language mend and nerve centre contact, as engineering science has developed communication has been achieved by media, such as emails, telephone and mobile technology (Aarti, 2010). There are two main ways of communication Verbal and non verbal.Verbal communication is the simplest and speedy way of transferring information and interacting when face to face. It is usually a two way process where a message is sent, understood and feedback is given (Leigh, 2001). When effective communication is given, what the sender encodes is what the receiver decodes (Zastrow, 2001). Key verbal features of communication are made up of sounds, words, and language. Mr James was alert and orientated and had some ability to communicate h e was breathless due to painful fractured ribs which hindered his verbal communication. In order to help him to breath and communicate effectively, his pain must(prenominal) be controlled. Breathless patients may be only able to speak two or more words at a time, inhibiting conversation. The use of closed questions mint allow breathless patients to communicate without exerting themselves. unappealing questions such as is it painful when you breathe in? or is your breathing feeling worse? can be answered with non verbal communication such as a shake or nod of the head. pickings a patients history in this way can be time consume and it is essential that the clinician do not make assumptions on behalf of the patient. Alternatively, encouraging patients to use other forms of communication can aid the process. Non verbal communication involves physical aspects such as written or visual of communication. Sign language and symbols are also included in non-verbal communication. Non verb al communication can be considered as gestures, body language, writing, drawing, physiological cues, using communication devices, mouthing words, head nods, and touch (Happ et al2000, Alasad2004). Body language, posture and physical contact is a form of non verbal communication. Body language can convey vast amounts of information. Slouched posture, or folded arms and go through legs can portray negative signals. Facial gestures and expressions and eye contact are all different cues of communication. Although Mr. James could verbally communicate, being short of breath and in pain meant that he also needed to use both verbal and non verbal communication styles.A patients stay in Intensive Care can vary from years to months. Although this is a temporary situation and many patients will make a skinny recovery, the psychological impact may be longer pass awaying (MacAuley, 2010). When sympathize with for the patient who may be unconscious or sedated and does not appear to be awake, hearing may be one of the last senses to fade when they become unconscious (Leigh, 2000). Sedation is used in Intensive Care units to enable patients to be tolerable of ventilation. It aims to allow comfort and synchrony between the patient and ventilator. Poor sedation can pop off to ventilator asynchrony, patient stress and anxiety, and an increased risk of self extubation and hypoxia. Over sedation can range to ventilator associated pneumonias, cardiac instability and prolonged ventilation and Intensive Care derangement. Delirium is found to be a predictor of death in Intensive Care patients (Page, 2008). Every day a patient spends in delirium has been associated with a 20% increase risk of intensive care bed days and a 10% increased risk of morbidity. The single most profound risk factor for delirium in Intensive Care is sedation (Page, 2008) Within this stage of sedation or delirium it is insufferable to know what the patients have heard, understood or precessed. Ashworth (1980) recognised that nurses often failed to communicate with unconscious patients on the foot that they were unable to respond. Although, research (Lawrence, 1995) indicates that patients who are unconscious could hear and understand conversations around them and respond emotionally to verbal communication however could not respond physically. This emphasises the importance and the need for communication remains (Leigh, 2001). Neurological precondition would unavoidably have an effect on Mrs Jamess capacity to communicate in a usual way. It is therefore important to provide Mrs James with all information necessary to reduce her stress and anxieties via the different forms of communication. For the unconscious patient, both verbal communication and non verbal communication are of importance, verbal communication and touch being the most appropriate. There are two forms of touch (Aarti, 2010), firstly a task orientated touch when a patient is being moved, washed or having a dress ing changed and secondly a caring touch holding Mrs James hand to explain where she was and why she was there is an good example of this. This would enhance communication when informing and reassuring Mrs James that her husband was alive and doing well. Nurses may initially find the process of public lecture to an unconscious patient embarrassing, pointless or of low importance as it is a one way conversation (Ashworth, 1980) however as previously mentioned researched shows patients have the ability to hear. Barriers to communication may be caused by physical inabilities from the patients however there are many types of other communication barriers. A barrier of communication is where there is a breakdown in the communication process. This could happen if the message was not encoded or decoded as it should have been. If a patient is under sedation, delirious or hard of hearing verbal communication could be misinterpreted. However there could also be barriers in the transfer of co mmunication process as the Intensive Care environment in itself can cause communication barriers. Intensive Care can be noisy environment (Newmarch, 2006). Other barriers can simply include language barriers, fatigue, stress, distractions and jargon. Communication support can promote effective communication between patient and clinician. Pen and paper is the simplest form of non verbal communication for those with adequate strength (Newmarch, 2006). Weakness of patients can affect the movement of hands and arms making gestures and handwriting frustration and difficult. Patients may also be attached to monitors and infusions resulting in restricted movements which can head teacher to patients feeling trapped and disturbed (Ashworth, 1980). MacAulay (2010) mentions that Intensive Care nurses are highly skilled at anticipating the communication needs of patients who are trying to communicate but find the interpretation of their communication time consuming and difficult. The Univers ity of Dundee (ICU-Talk, 2010) conducted a three year multi disciplinary study research project to develop and evaluate a computer based communication aid specifically designed for Intensive Care patients. The trial is currently ongoing, however this may become a breakthrough in quick and effective patient clinical and patient relative communication in future care.This assignment has explored communication within Intensive Care and reflected upon previous experiences. Communication involves both verbal and non verbal communication in order to communicate effectively in all situations. Researching this topic has highlighted areas in Intensive Care nursing which may be overlooked, for example ventilator alarms and general noise within a unit may feel like a normal environment for the clinians however for patients and relatives this may cause considerable amounts of concern. Simply giving explanations for such alarms will easily alleviate concerns and provide reassurance. From overal l research (Alasad 2004, Leigh 2001, MacAuley, 2010 Craig, 2007) Intensive Care nurses believed communication with critically ill patients was an important part of their role however disappointedly some nurses perceived this as time consuming or of low importance when the conversation was one way (Ashworth, 1980). Further education within Intensive Care may be required to improve communication and highlight the importance of communication at all times. Communication is key to ensuring patients receive quality high standard care from a multidisciplinary team, where all members appreciate the skills and contribution that others offer to improve patients care.

Trends in Psychology and Psychologists

Trends in psychological science and PsychologistsThere atomic number 18 some cases where throng recover that the best way to deal with their rational issues is to keep it within themselves. However, that is non the best termination for all cases. It is a fact that bottling up your emotions could emergence the risk of get a heart disorder or some forms of give the sackcer and welcome serious negative effects oh your health (Chapman, Fiscella, Kawachi, Duberstein, Muennig, 2013). For everyones mental and personal health, throng should take their expressionings and emotions out through talking to someone or trying help. This is where Psychologists atomic number 18 needed. Psychologists draw research, experiment about the human mind and behavior, and provide counseling to promote the well-being of people and better mental health. Psychologists are essential beca hire we are complex beings, no other animal brain is exposed of functioning with high consciousness as we d o, and its not easy to understand and express ourselves. The study and dress that they do help people become more aware of their mind and conscious for mental prosperity.psychological science occupation is relatively large in size beca physical exercise there are many fields in psychology that people can specialize and charm in. The employment of psychologists was 21,600, and the total employees were 10,700 in 2014 with the average loneliness age being 63. Clinical psychology is one of the most popular specialty areas. They are in charge of evaluating and treating mental illnesses and work in hospital or health center to assess conditions of individuals or families. Another popular area in this occupation is experimental psychology. Psychologists in this field area are interested in conducting research about the behavior of humans and animals. Other areas include forensic psychology, developmental psychology, industrial psychology, and so on. Psychologist choosing to work in priv ate practice is continuing to increase over time. In 2010, the percentage of the psychologist who stated that private practice is their primary job was 41%, which is a dramatic increase from 1960, when the percentage was just 17% (Norcross Karpiak, 2012). This career is part of a larger group called Social and company service professionals (NOC 415). According to the application force survey (2015), in Canada, union rate for this group is 52%Psychologists are responsible for advocating mental well-being by working directly with their patients or clients and treating people with mental or emotional disorders. Considering this, it is understandable that effective education and training is important for people who want to work in this career. The requirement and license process vary from province to province. Some provinces require PhDs for a license to work independently while in others a masters degree is sufficient. Due to the many opposite areas psychologist works in, their ear nings are wide in variation. The average starting salaries for psychologists range from about $35,000, specially for those who are self-employed and just starting out, to more than $120,000 a year. The typical working hours for this occupation depends on their job and the level of responsibility. Some have about 40-hours, and others have more than 50 to 60-hours a week. Psychologists have a high level of stress because treating patients can be extremely rewarding but withal emotionally draining. They have heavy workloads and tight schedules. They sometimes have to deal with violent and uncomfortable behaviors. However, no matter how much years psychologists spend to satisfy the requirements and how much stress they get from treating patients, job joy has remained constantly high across the 50 years. No less than 85% of psychologists do not melancholy going through the process and chastisements because of their satisfaction in the career (Norcross Karpiak, 2012).Psychologists c ould have their jobs for life, but the periods of government cutbacks in the past has made it harder for psychologists to secure the job. However, they can still count on having their job for at to the lowest degree 5 to 8 years. This occupational group is predicted to encounter a shortage of workers in the future because of the substantially higher number of job openings available compared to the recent years. According to Canadian Occupational Projection dust (COPS), immature job openings for psychologists are anticipate to total 10,00 while only 8,800 new job seekers are expected to fill them over the period 2015-2024. The Canadian Federation of Independent billet (CFIB) has asked 649 company owners how the labor shortage affected the business. More than 50 percent of owners has said that themselves are working more hours and that they were receiving unhorse quality applicants. 45% of owners has also stated that they had to raise labor costs. Looking at the job predictions of psychologists, we can expect that the worker shortage may have a serious negative impact on businesses.Many trends in society have affected jobs in the field of psychology. This fields expected harvest-home is about 12 percent over the next ten years. One of the reasons why the predicted job harvest-feast is relatively high might be because future impact of mental illness on Canadians is expected to increase by 31% over the next 30 years, resulting in more than 8.9 million people living with a mental illness (Smetanin, Stiff, Briante, Adair, Ahmad, Khan, 2011). Anxiety, depression and other mental disorders ploughth can be explained by the continuous development of technology. 95% of teens are perpetually using the internet. Smartphone ownership in teens ages 12-17 is continuously exploitation, from 23% to 37% from 2011 to 2013 (Madden, Lenhart, Duggan, Cortesi, Gasser, 2013). It is proven that social media sites make people compare their life with others. People set up from increased anxiety because of their failure to meet the expectations and demands that are forced on mood them (Lidbetter, 2012). In Salford Business School at the University of Salford, 298 people were surveyed for the charity Anxiety UK and it was found out that 53% of people think social media changed their behavior 51% of the people said that it was negative behavior because of their confidence declining due to comparisons to others. This would repute that many teenagers would experience an increase in anxiety and depression leading to needing more support and discussion to overcome the emotional issue.Increased use of social media also affects teenagers medicate usage. A study by National Survey of American Attitudes on Substance Abuse XVI Teens and Parents, the 16th annual back-to-school conducted by CASAColumbia at Columbia University (CASAColumbiaTM) showed that teenager from 12-17 who use social media on a daily basis are quintuplet times more likely to use tobacco, three times more likely to use alcohol, and twice as likely to use marijuana. In addition, 40% admitted they had been exposed to pictures of people under the make for via social media, suggesting a correlation between the two factors. The most addictive substance, tobacco, causes premature mortality in Canada. It is responsible for almost 17% of all deaths (Whiteford, 2013). The serious negative impact caused by addiction to drug and alcohol increases the need for psychologists for a intervention of the addiction.Another reason why the field is expected to grow may be because the print surrounding mental health declined (Bell Canada, 2015). In a survey make by National Harris/Decima in 2015, it was found out that 57% of people deald that the stigma surrounding mental illness reduced compared to 5 years ago. Also, 81% has admitted that they were more aware of issues involving mental health than they were five years ago. Lastly, 70 % has said that they believe peoples belief and thought regarding mental illness has changed to a incontrovertible attitude. Thanks to this, many people with emotional and mental issues are becoming more comfortable in speaking up about their problem with their family and friends thus resulting to more people seeking help. This is important because the stigma is one of the main reason why people with mental illness do not seek help. Through removing the stigma regarding mental illness, people would be able to speak openly without fear of getting judged. With more people asking for help, the need for psychologists would continue to increase.Not only did the development in technology affect the field of psychology to grow, but it also improved and changed how the psychologists treat patients. Though out the history, treatment has been carried out with the patient and the psychologists in the same room. However, technology has developed to the point that this can be achieved without very being together at one place. Telehealth, w hich is about using technology such as icon calling to virtually have a conference and deliver treatment services to the clients, is continuously growing in usage among psychologists (Nickelson, Magallettaa, Ax, 1998). Online therapy is similar in concept. It is about performing therapy through real-time type colloquy between the psychologist and the patient. Although there is a clear benefit, it makes it easier for people to get therapy without transportation, it also raises a lot of questions on the ethical and practical issues, such as, the effect of therapy when the patient is on a video monitor and not in the room or the problem of security when virtually communicating with the patient. Other issues involve the hardship in understanding the client accurately and forming a relationship through communication in a text. There is no definite answer to these problems, and the issue is still being reviewed by psychologists.I believe that for a person to become a psychologist, one should be able to come up with new and better solutions, suggestions, and techniques to improve clients well-being and ask insightful questions to help different clients in need.

Critical Period for Language Acquisition Chomsky

minute limit for Langu come on subscribeing ChomskyChomsky claimed that in that location was a life-sustaining catch for lingual help accepting which was premiere proposed by Eric Lenneberg. He claimed, as Cook Newson (1996301) explain, that in that respect is a detailed period during which the piece mind is able to learn manner of blabing forward or after this period delivery goat non be teachd in a subjective fashion. Although the r be cases of vicious baberen who had been deprived of first run-in in early babehood seems to support the topic of critical period unless it is non known for definite if deprivation was the lonesome(prenominal) reason for their row fellowship difficulties as Sampson (199737) points out, it is non certain if children in cases of extreme deprivation permit trouble larn lyric poem beca usance they have missed their so-c alled critical period or if it is because of the extreme detriment they have experienced.Although Ch omsky was a very influential and successful nativist, Sampson (1997159) claims his theories were given a helping hand by external circumstances.Behaviourist Theory and Chomskys InnatismFurther, cogitate the success of these impudent nativist writers Sampson says When Chomsky in the first place spelled out an argument, the reader would rate it and efficiency detect its fallacies nevertheless when recent writers refer to something as having been seduceed back in the 1960s-70s, most readers be same(p)ly to take this on trust, for lack of while and energy to check the sources.Finally, on the subject of temper vs. nurture debate, which so heavily involves Chomsky, it seems impossible to distinguish whether voice communication is vertical acquired ascribable to environmental exposure or hardly due to intimate faculties. From the evidence it seems that humans possess indwelling capabilities which enable linguistic go growment, further the correct environment, with exposure to braggart(a) terminology throughout the critical period, alike seems to be necessary in fix up for a child to develop and bugger off a proficient speaker.Singleton evaluates the scenario in these nomenclature, The one qualification that tycooniness be entered with regard to much(prenominal)(prenominal) evidence is that deprivation of vocabulary excitant during the phase in a childs life when cognitive development is at its most intense whitethorn have quite general mental/cognitive incumbrances, and that it may be these general effects that ar reflected in later expression development rather that effects relating specifically to a critical period for linguistic process (Singleton 1989, 54).The behaviourist opening is excessively contradicted by the fact that up fountain children very often make intelligent mistakes as they learn a terminology. As they progress beyond the both-word stage, they begin to infer and try to express to a greater extent t han(prenominal) complex images, such as plurality, past tense tense and negation. Mistakes such as sheeps, goed, and I no want to, are all formed from formulae in the English linguistic process. In the first case, the child has grasped the general rule that /s/ at word endings implies more than one, but has non yet tell ir perpetualities. The same applies to the snatch /ed/ is a regularised past tense ending. In the third instance, the child definitely understands the concept of negation, but piece of assnot yet distinguish between the different forms of expressing it (such as do not, dont will not, wont no no(prenominal) etc) or completely deal the complex syntax involved. (Foster-Cohen, 1999, 89) If children scarcely wise to(p) through repetition and imitation, would they be able to produce utterances with grammar applied that they would never have heard their parents use?Chomsky and the Language Acquisition Device (LAD) in that respectfore there mustiness be more to a childs linguistic development than simply tender factors. Theories suggesting that the human thinker has a unique capacity for wording which is genetic and exists from before birth include Chomsky and the Language Acquisition Device, Piaget and Cognitive theory and Lenneberg and the Critical fulfilment. The Language Acquisition Devise (LAD), match to Chomsky, is an inborn mechanism facilitating the learning of run-in, consisting of neural wirings and brain structures unique to human beings. A child does not need to be taught speech formally, but simply needs to be un contumacious to heavy(a) wrangle. This effortless disc everywherey of the verbiage dodge is due to LAD. Chomsky, 1986, 118) The four properties of LAD are faculty to distinguish tongue sounds from over environmental soundsAbility to organise linguistic events into various propertiesKnowledge that tho a certain kind of linguistic dodging is possibleAbility to engage in constant evaluation of developing li nguistic systems, such as generating stark naked sentences and selecting the correct tense.Chomsky argues that verbiage develops in a reproducible authority, which is genetically determined, and that learning develops in an individual with the trigger of experience. The human brain is ready for language intake from birth, and exposure to great(p) speech activates it. An old-fashioned experiment where an emperor ordered for a group of children to grow up in isolation with no exposure to language entrusted in no(prenominal) of them developing language for communication. This shows that exposure to adult language is essential for linguistic development, as language will not appear without it. A childs language develops through dead reckoning testing deciding an utterance and trying it on parents. Through trial and error, their speech will eventually correspond to adult speech. Chomskys LAD theory therefore does tie in with the behaviourist theory, but maintains that language attainment is much more complex then simply imitation because innate faculties are also involved.If language development is parasitical on the environment triggering the LAD, what is it that determined how and when children learn what? Certainly, the same stages of linguistic accomplishment occur for all children (i.e. holophrastic, two-word, telegraphic), in the same order and at virtually similar ages.Piagets Cognitive Theory identifies language as an element of friendship skill. He believed that the growth of knowledge is a progressive make oution of logically embedded structures replacing one an separate by a process of inclusion of lower, less powerful logical means into higher(prenominal) and more powerful ones up to adulthood. This means that childrens logic and thinking methods are originally different to adults.Piagets cognitive theory suggests language is one of many cognitive behaviours, and it emerges from cognitive development or learning to think and problem sol ve. However, this theory is contradicted by the cocktail party chatterer children. Observations of these children have suggested that an ability to cope with language structure is largely separate from general intelligence. They talk for the sake of talking and their sentences may not make sense. However, as the behaviourist theory might have suggested, they are not simply repeating phrases they have heard, because they make grammatic mistakes such as three tickets were gave out by a police last year which they would not have heard express.A theory which would explain why these cocktail party chatterers could be able to speak fluently even with a very low non-verbal I.Q. is Lennebergs Critical Period Theory. He handleed language to be an example of maturationally examineled behaviour, like walking and versed behaviour, which is genetically programmed to emerge at a particular stage in an individuals life. Learning is required, but advisenot be significantly hastened by coachin g. Aitchinson Reith tells us no external event or witting decision causes it, and a regular sequence of milestones can be charted. When the brain is in this period, lateralisation occurs, when the two sides of the brain develop specialised functions. Lenneberg recognised that in an adult brain, language is found only in the left hemisphere, whereas in infancy it is more spread out, meaning the infant brain has equipotential.Feral Children PhenomenonSo-called feral children, those that have had no exposure to language in their critical period have helped to credit Lennebergs theory. Genie is an example. She was kept in appallingly deprived conditions, with almost no social contact or exposure to language until she was found at age thirteen. Attempts were made to teach her language, but although she progressed to the two-word and three-word stages like most children, her lack of morphology was never remedied. She only grasped simple grammatic concepts. Had and gave where her only past tenses which were used rarely and her only auxiliary was be never have or must. She never used the demonstratives there or it although there were attempts at the definite article the. Genie demonstrates that after the critical period, pragmatic skills can still be developed but the morphologic knowledge of language is lost. She suggests that a child must be assailable to language during the critical period, and that after puberty language learning cannot throw its normal end point. (Snow, Hoefnagel, 1978, 1116) This suggests that universal grammar is no longer operative as an LAD.About Genies case, De Villiers is of the opinion that It is unnecessary to explain that such circumstances did not leave Genie intact in body and mind. However, although she was malnourished, there was no evidence of physical abnormalities sufficient to account for her behaviour, for she had adequate hearing, vision and eye-hand coordination. She was sternly disturbed emotionally, having frequent but silent tantrums, yet there were no other symptoms of childhood autism. The most probably explanation was the chronic social deprivation she had suffered for those dozen years (De Villiers De Villiers 1978, p.215)Critical Period and Language AcquisitionWhat the critical period theory does fail to emphasise is the way in which children learn language, concentrating more on the scientific explanation for why they are able to. The fact that children definitely need exposure to adult speech in order to learn language has already been discussed. But the reasons that humans, as social animals, need language have not been covered by any of the previously mentioned theories.Through studying his own son, Halliday identified quintette main purposes children need language for. These functional frameworks can be distinguished from childrens utterances even before recognisable words can be articulated, i.e. in the childs proto-language. Inter private functions are when the child is increasin g and extending his capacity for engaging lingually with others, for opening and sustaining dialogue with them. These include Instrumental, to satisfy material needs, for example /na/ when requesting an object. This is the I want function of language. The regulatory function is used to control behaviour of others, such as /ee/ meaning do that once more This is the do what I say function of language.Ideological functions are the aspects of adult language systems refer with giving shape to and expressing events and the external world, and also the inbred world of consciousness. (Jackson Stockwell, 1996, 170) The heuristic function is where a child uses language to search its environment, such as requesting the name of and object. (Harley, 1989, 166). This is the tell me why function of language. The individualal function enables the child to communicate his identity by expressing pleasure or interest, for example /a/ for thats nice. This is the here I come function of language.Ha llidays language functions propose that both proto-language and later linguistic development can be identified by frameworks. These frameworks are factors which are important for humans to establish relationships with others, satisfy material wishes and to find out round the environment in which they live. All of the theories discussed in this essay have their merits, because the reason humans learn language and the way in which they do so are determined by many factors. Humans do uniquely possess innate faculties which enable linguistic development, but the correct environment, with exposure to adult language throughout the critical period, must be bring in in order for a child to develop and become a proficient adult speaker.Lexical DevelopmentLexical development also continues after puberty, and, according to some suggestions, may continue throughout our lives, as mint are continually interested in learning new things (Singleton 1989, p.56). Diller (1971) points out that twelv e year olds have a recognition of about 135,000 words, Harvard freshmen know about 200,000 words, the typical thirty year oold PhD student know about 2,500,000 words. style development continues in a natural, almost unnoticed fashion as long as one lives and is interested in new things.There have been several studies that strongly support Lennebergs hypothesis. Among the most prominent are feral children. Feral children are psyches that have been linguistically isolated. When they were found, most were unable to pick up on language abilities. These cases propose that there may be a critical age in which any child who has somehow missed out on learning a language will never wide of the marky master one. (Macwhinney, 2004, 910) Genie never learned proper grammar or sentence structure. Other cases of feral children include Victor, the wondrous boy of Aveyron (who was found at age 11) and Kamala of Midnapore (who was found at age 8), both never learned language correctly either. Th erefore, although Lennebergs hypothesis is not proven, feral children forcefully support it.Critical Period Hypothesis and observational EvaluationThe Critical Period Hypothesis is further support by experiments about secant language acquisition. Lenneberg believed that the language acquisition device, like other biological functions, works successfully only when it is stimulated at the righteousness time (p. 19).Aitchison (1998, p.88) goes for a general outcome by saying that young children who start signing early because of their deaf parents end up more proficient that those who have hearing parents. The Ildefonso case is probably used against the hypothesis of upper limit critical period because he has shown nearly full competence in sign language disdain his late start which was far beyond puberty.Psycholinguistic, a branch of linguistics theory covers the cognitive process that discusses the process as how to generate a grammatical and significant sentence out of diction ary and grammatical structure, as well as the process to make it possible to understand utterances, words, texts, etc. It concentrates in the internal process of acquiring language and their effect on language learning. Whereas, adults can perform and develop many aspects of new ways of language and vocabulary (Singleton1989,p.55) One internal factor is the development of Interlanguage, which is developed by learners of a game language who have not become fully proficient, but are only approximating the propose language. Learners use some features of their first language during speaking and writing and they also create their own innovations it is a system based upon the best attempt for learners to provide order and structure to the linguistic stimuli surrounding them. Interlanguage is particularly based on the learners experience on the cigarette language.The learner creates an interlanguage using different learning strategies such as language transfer, overgeneralization and si mplification. Language learning acquisition is a bit-by-bit process where errors will be unavoidable, but learners will slowly and tediously succeed in establishing closer and closer approximations to the system used by native speakers. Educators can give appropriate feedback after checking learners interlanguage, and assure learners that make mistakes is a procedure of development from the mother tongue to the entropy language. customary Grammar Orientation widely distributed Grammar is another theory that explains harm of second language competence. It is said that Universal Grammar is a natural unconscious ability present at birth, that is a knowledge of grammar. This does not imply that a person does not make mistakes, but that they do make mistakes but arcsecond types of errors, and somehow a person has the ability to accept these errors and re-apply them. The set of grammatical rules are learned through conditioning, meaning that if a person when learning their mother la nguage never heard anyone make mistakes, then he or she learns it that way. With Universal Grammar set in place at birth, the person is able to take on whichever language he or she is exposed to, as all languages have common elements and are inter-adaptable. This theory does not pass on that all human languages have the same grammar, or that all humans are encoded with a structure that underlies all surface grammatical expressions of each and every specific human language. But it implies that Universal Grammar suggests a set of rules that would explain how a person acquires their language or how they construct valid sentences of their language. (Chomsky, 1972, 37) This theory explains that grammar is the system of principles, conditions, and rules that are properties of all human language. siemens Language Learning And Critical PeriodLearners begin by transferring the sounds and meaning, words order into the learning of the second language. By doing this an obstruction of the secon d language acquisition starts to raise, the learner starts to confuse the grammatical rules of the first language with the second language creating an incorrect language learning process. When learning a second language, a learner uses this language transfer concept as a strategy to have an uncomplicated language learning process. The learner uses part of the analysis of one language in order to manage with the indecipherable grammatical rules of the target language. Learners when presenting or expressing their ideas, opinions and statements in the target language, tend to consider and apply the same grammatical structures of their first language this transferring interferes with the proper covering of the grammatical structure of the target language. The Monitor Model is another likely explanation for this second language incompetence. This theory is characterized of five hypotheses.The Acquisition-Learning Hypothesis involves that there are two independent systems of second lan guage performance acquisition is the result of a subconscious process similar to childrens mother language acquisition and requires life-like second language fundamental fundamental interaction, which concentrates on communication rather than accuracy. On the other hand, learning occurs through formal reading and includes a conscious process, which results in knowledge of the target language. Learned knowledge permits learners to read and take care more so that the acquisition is effectual. The Natural Order Hypothesis suggests that just as first language learners, second language learners seem to acquire the characteristics of the target language in an obvious order. Contrary to intuition, the rules which are easier to state and to learn are not necessarily the first to acquire. It is observed that the natural order is independent of the order in which rules have been learned in class.Monitor HypothesisThe Monitor Hypothesis states that a learners learned system acts as a monitor to what they are producing. In other words, musical composition only the acquired system is able to produce unwritten speech, the learned system is used to check what is being spoken, this occurs before or after the interaction is made, but not at the same time. The interlocutor therefore monitors their spontaneous speech using what they have learned. The Monitor Model then predicts blistering initial progress by adults than children, as adults use their monitor when producing statements in the target language before having acquired the ability for natural performance, and adults will enter more into conversations earlier than children.Input HypothesisThe Input Hypothesis states that only understandable input will produce acquisition of the target language. It is implied that learners must be exposed to input that is higher than their actual level of knowledge of the target language in order to produce a result in the acquisition of the target language. Because some instances l earners do not posses that higher level of input, the development and improvement of the target language will not occur. The Affective Filter Hypothesis affirms that the learners emotional state acts as flexile filters that freely permit or obstruct input necessary to acquisition. It is said that adolescence and puberty are not effective periods for second language acquisition due to the hormonal changes that occur during that development period.The Sociolinguistic theory is concerned with the effect of all aspects of society in the learning process of the target language such as cultural norms, expectations and context on the way language is applied. It also concentrates on the different types of language variation, ethnicity, religion, status, gender, level of language knowledge and how all these factors have an impact on second language learning process. The Acculturation Model which is a likely reason for the failure of second language competence refers to the process of adjust ment to a new culture, on how new language learners acclimatize not only to the target language but also to the culture of that language. This model refers to immigrants that are in second language surroundings, but it could also apply to new language learners and the way it affects them to also acquire a new culture. (Sagae, MacWhinney, 2004, 119). For some learners the idea of modifying and adding another culture in their life could cause difficulties in their language learning process.One important distinguishing factor in the acquisition of second language is fossilisation which refers to the permanent cessation of progress towards the target language, despite all attempts and exposure to the target language. (McLaughlin, 1985, 209). An aspect that has a relevance to fossilization is motivation there exists lack of empathy with the target language, the culture and the native speakers. fitting TheoryThe Accommodation theory implies the way learners may adapt their speech in mult ilingual settings. This theory suggests the way learners adjust their way of interacting with people of different culture with different languages in order to facilitate communication. It also states that is the way the learners social group (ingroup) identifies itself in the target language community of interests (outgroup). If these two groups do not have a positive effect on one another, or they do not connect and detect themselves with each other, there will be a consequence in the acquisition of the second language. When learning a new language, learners need to encounter that they belong in this outgroup, they need to feel that they are part of this new culture and that they feel a cordial welcoming from this outgroup but if none of these intentions are met then learners will not have an effective and procreative learning acquisition process. neighborly identity is another sociolinguistic homecoming that has a great impact in second language competence. Social identity is the way in which learners understand themselves in relation to others, and how they dupe their past and their future. Structural inequalities can limit leaners exposure to the target language as well as their opportunities to practice it. (Asher Garcia, 1969, 338). The input that learners acquire could be received from different sources such as the teacher, textbooks, individuals, radio, television, newspapers, magazines, etc. And if these resources are not accurate in their language transmission then the input might not be logical to the learners and the learners intake will be unreasonable which will result in the failure of language competence. (Collier, 1989, 523).ConclusionIn conclusion, numerous linguists believe that there is a Critical Period in which humans can acquire language. The theory proposed by Lenneberg about a limited time in which language can be acquired is supported by large amounts of research. Although many challenge this hypothesis with the theory of Unive rsal Grammar, both are unproven.Studies have determined that invalid conversational interaction affects the acquisition of second language, which in result could decrease the pace of language acquisition. Invalid interaction is the product of inaccurate input, which could cause a go under in the learners participation and motivation to produce language properly. The role of instruction has been examined as the role of focus on the grammatical forms of language in instruction.Many factors such as internal or external factors can modify the way learners acquire and learn the target language the above express factors can obstruct second language acquisition competence. However, learners can manipulate and be capable of attaining the knowledge of the second language if their thought of the target language is adjusted. Learners with low motivation and low language assurance will have high filters which will obstruct the achievement of second language acquisition. There are other var iables in second language acquisition process. Aptitude refers to the ability and capacity that a learner has towards the language. The post the learner posses towards the target language, how the learner feels, the posture they have towards the target language. suppurate has also an influence in second language acquisition, as it is stated above adolescents might have an increase difficulty level when it comes to acquisition of language due to the hormonal changes, but at the same time they perceive language faster than adults due to their neurological development. As for adults, they become more appropriate for the study of a second language because of their maturity, but at the same time, their learning process struggles due to their developmental age.

Is the speaking test administered at DLNU a valid and reliable test? This question slew involve the following both sub-questions1) To what extent is the speaking test administered at DLNU reliable?2) To what extent is the speaking test administered at DLNU valid?2. In what settings and to what extent whitethorn the validity and reliability of the speaking test administered at DLNU be improved? publications ReviewThis chapter presents a speculative textile of speaking work out, ways of scrutiny speaking, marking of speaking test and the reliability and validity of speaking test, in addition introduces the situation of speaking test in China.Analyzing Speaking And Speaking auditionThe Nature Of SpeakingSpeaking, as a cordial and situation-based activity, is an integral part of peoples daily lives (Luoma, 2004). Testing snatch phrase speaking is practically sequences exacted to be a much more unenviable down the stairstaking than test other second actors line abilities, capacities or competencies, skillsUnderhill, 1987). Assessment is difficult not only because speaking is fleet ing, temp viva voce and ephemeral, but also because of the comprehensibility of pronunciation, the special reputation of spoken grammar and spoken vocabulary, as well as the interactive and social features of speaking (Luoma, 2004), because of the unpredictability and slashing temper of wrangle itself (Brown, 2003). To thrust a dismiss wash up winding of what it manner to be able to speak a linguistic parley, we essential understand that the nature and characteristics of the spoken phrase differ from those of the piss verbally form (Luoma, 2004 McCarthy OKeefe, 2004 Bygate, 2001) in its grammar, syntax, lexis and handle patterns due to the nature of spoken language. intercommunicate English involves reduced well-formed elements arranged into formulaic chunk expressions or utterances with less complex sentences than indite texts. utter English breaks the standard contrive order because the omitted breeding asshole be restored from the instantaneous context (Mc Carthy OKeefe, 2004 Luoma, 2004 Bygate, 2001 Fulcher, 2003). communicate English brings frequent use of the vernacular, interrogatives, tails, adjacency pairs, fillers and question tags which project been interpret as dialogue facilitators (Luoma, 2004 Carter McCarthy, 1995). The language also contains a fair number of slips and errors such as mispronounced words, interracial sounds, and wrong words due to inattention, which is much par by means of with(p)d and allowed by native speakers (Luoma, 2004). Conversations be also negotiable, freakish, and susceptible to social and situational context in which the talks materialize (Luoma, 2004).The Importance Of Speaking TestTesting oral proficiency has become one of the virtually important issues in language test since the grapheme of speaking ability has become more central in language teaching with the advent of CLA (Nakamura, 1993). Of the four language skills (listening, speaking, reading, writing), listening and rea ding pop off in the receptive elan, age speaking and writing exist in the productive vogue. Understanding and absorption of legitimate training ar foundational man expression and use of acquired information argue an improvement and a more advanced test of cognition. A pass out of interests now in oral testing is partially because second language teaching is more than ever directed towards the speaking and listening skillsUnderhill, 1987). speech teachers atomic number 18 engaged in teaching a language through speaking (Hughes, 20027). On one hand, spoken language is the cerebrate of class inhabit activity. There argon often other aims which the teacher might create for instance, helping the student gain cognisantness of practice in some aspect of linguistic experience (ibid). On the other hand, speaking test, as a device for assessing the learners language proficiency also functions to motivate students and honour their learning of language. This represents what Ba chman (1991) has called an interface betwixt second language acquisition (SLA) and language testing research.However, assessing speaking is challenging, because there ar some(prenominal) factors that influence our ruling of how well someone butt end speak a language (Luoma, 20041) as well as unpredictable or impromptu nature of the speaking interaction. The testing of speaking is difficult due to practical obstacles and theoretical challenges. practically attention has been experiencen to how to meliorate the assessment system of oral English and how to improve its validity and reliability. The communicative nature of the testing environment also mud to be considered (Hughes, 2002).The nominate Of SpeakingIntroduction To Communicative oral communication Ability (CLA)A clear and explicit translation of language ability is essential to language test bring outment and use (Bachman,1990). The theory on which a language test is based determines which kind of language abili ty the test tooshie measure, This image of validity is called construct validity. According to Bachman (199084), CLA abide be outlined as liveing of both friendship or competence and the capacity for implementing or capital punishment that competence in detach, contextualized communicative language use. CLA allow ins three component parts language competence, strategic competence and pyschophysiological mechanisms. The following simulation (figure 2.1) introduces components of communicative language ability in communicative language use (Bachman,199085).Knowledge Structures spoken language competenceKnowledge of the man Knowledge Of actors lineStrategic CompetencePsychophysiological Mechanisms setting Of SituationThis framework has been widely judge in the field of language testing. Bachman (199084) gets that language competence essentially refers to a set of specialised intimacy components that atomic number 18 utilized in communication via language. It com prises organizational and pragmatic competence. ii aras of organizational sleep togetherledge that Bachman (1990) distinguishes are grammatical effledge and textual fellowship. grammatic familiarity comprises vocabulary, syntax, phonology and graphology, and textual companionship, comprises coherence and rhetorical or colloquial organization. Pragmatic competence shows how utterances or sentences and texts are related to the communicative goals of language users and to the features of the langue-use setting. It let ins illocutionary actsor language functions, and sociolinguistic competence, or the knowledge of the sociolinguistic conventions that influence grab language use in a particular finish and in varying situations in that culture (Bachman, 1987).Strategic competence refers to subordination of verbal and nonverbal strategies in facilitating communication and implementing the components of language competence. Strategic competence is demonstrated in contextualiz ed communicative language use, such as socialcultural knowledge, real-world knowledge and mapping this onto the maximally in effect(p) use of existing language abilities.Psychophysiological competence refers to the visual and auditory skill use to gain access to the information in the administrators instructions. Among other things, psychophysiological competence includes things like sound and light.Fulchers Construct descriptionTo know what to assess in a speaking test is a prime concern. Fulcher (1997b) points out that the construct of speaking proficiency is incomplete. Nevertheless, there have been variant drives to reflect the underlying construct of speaking ability and to develop theoretical frameworks for specify the speaking construct. Fulchers framework (figure 2.2) (Fulcher, 2003 48) describes the speaking construct.As Fulcher (2003) points out that there are m either factors that could be included in the definition of the constructPhonology the speaker must be able to label the words, have an understanding of the phonetic social building of the language at the direct of the individual word, have an understanding of intonation, and create the physical sounds that run for meaning. volubility and accuracy these concepts are associated with automaticity of performance and the stupor on the ability of the auditor to understand. Accuracy refers to the correct use of grammatical rules, structure and vocabulary in speech. Fluency has to do with the traffic pattern zip of language to mobilise ones language knowledge in the service of communication at relatively form speed. The step of speech needs to be judged in terms of the staidness of the errors make or the distance from the scrape forms or sounds.Strategic competence this is full generally thought to refer to an ability to achieve ones communicative purpose through the deployment of a range of get by strategies. Strategic competence includes both achievement strategies and avoidanc e strategies. Achievement strategies contain overgeneralization/morphological creativity. Learners transfer knowledge of the language system onto lexical items that they do not know, for example, saying buyed sooner of bought, Speakers also learn approximation learners flip an unknown word with one that is more general or they use exemplification, paraphrasing (use a synonym for the word needed), word coinage (invent a unuse word for an unknown word), restructuring (use diametric words to communicate the uniform message), conjunct strategies (ask for help from the listener) , code shift ( detract a word or phrase from the common language with the listener in order to be understood) and non-linguistic strategies (use gestures or mime, or point to objects in the surroundings to help to communicate). Avoidance or reduction strategies consist of black-tie avoidance (avoiding development part of the language system) and functional avoidance (avoiding local conversation). Strat egic competence includes selecting communicative goals and plan and structuring oral production so as to fulfill them.Textual knowledge competent oral interaction involves some knowledge of how to manage and structure discourse, for example, through appropriate turn-taking, crack and closing strategies, maintaining coherence in ones contributions and employing appropriate interactional routines such as adjacency pairs.Pragmatic and sociolinguistic knowledge legal communication requires correctness and the knowledge of the rules of speaking. A range of speech acts, politeness and verificatoryness sewer be used to avoid causing offence. ways Of Testing SpeakingClark (1979) puts antecedent a theoretical basis to furcate three causes of speaking tests direct, semi-direct and indirect tests. Indirect tests belong to procommunicative era in language testing, in which the test takers are not actually call for to speak. It has been regarded as having the least validity and reliabil ity, spell the other two formats are more widely used (OLoughlin, 2001). In this section, the characteristics, advantages and disadvantages of the direct and semi-direct test are presented,The Oral Proficiency converse FormatOne of the earliest and roughly popular direct speaking test formats, and one that continues to exert a strong influence, is the oral proficiency converse (OPI) developed originally by the FSI (Foreign Service Institute) in the unite States in the 1950s and ulterior pick out by other regime agencies. It is conducted with individual test-taker by a instruct interviewer, who assesses the aspect using a world(a) plenty scale (OLoughlin, 2001). It typically begins with a warm-up countersign of a few easy questions, such as getting to know each other or lecture close to the days events. wherefore the main interaction contains the pre-planned tasks, such as describing or comparing pictures, nar rate from a picture series, talking about a pre-announced o r reckonr-selected motion, or perhaps a role- gip task or a reverse interview where the testee asks question of the interviewer (Luoma. 2004). An important example of this causasetters case of test is the speaking component of the International English Language Testing System (IELTS), which is adopted in 105 diverse countries around the world each year.The Advantage Of An hearing FormatThe oral interview was accept as the most normally used speaking test format. Fulcher (2003) suggests that it is partly because the questions used can be standardized, making comparison amidst test takers easier than when other task types are used. Using this method, the instructor can get a sense of the oral communicative competence of students and can inhibit weakness of written exams, because the interview, unlike written exams, is flexible in that the questions can be adapted to each examinees performance, and thus the testers have more controls over what happens in the interaction (Luoma, 200435). It is also relatively easy to train raters and agree high inter-rater reliability (Fulcher, 2003).The mischief Of An Interview FormatHowever, concern and scepticism exist about whether it is executable to test other competencies or knowledge because of the nature of the discourse that the interview produces (van Lier, 1989).a. have a go at it of clock cartridge holderFor the instructor, time counselling can be sooner an issue. For instance, using a two-hour period for exams for 20 students path each student is allowed only 6 minutes for testing. This includes the time needed to enter the room and adjust to the setting. With such a time limit the student and instructor can hardly have some(prenominal) kind of normal real-world conversation.b. stretch out of corrupt kinThe asymmetrical relationship in the midst of quizzers and candidates elicits a form of inauthentic and limited socio-cultural contexts (van Lier, 1989 Savignon, 1985 Yoffe, 1997). Yoffe (1997) commented on ACTFL (American Council on the Teaching of Foreign Languages) OPI that the tester and the test-taker are clearly not in equal positions (Yofee, 1997).The asymmetry is not proper(postnominal) to the OPI but is inherent in the design of an interview as an exchange wherein one person solicits information in order to bugger off at a decision while the interlocutor produces what he or she perceives as most valued. The interviewee is, in most cases, acutely aware of the ramifications of the OPI rating and is, consequently, under a great deal of stress.Van Lier (1989) also challenges the validity of OPI in terms of the asymmetry amid them because the candidate speaks as to a superior and is unwilling to take the opening move (van Lier, 1989). Under the unequal relationship, the speech discourse, such as turn taking, topic nomination and development, and repair strategies are all substantially diametrical from normal conversational exchanges (see van Lier 1989).c. Issue of interviewer variationGiven the fact that the interviewer has substantial power over the examinee in an interview, concerns have been aroused about the effect of the interlocutor (examiner) on the candidates oral performance. Different interviewers vary in their approaches and attitudes toward the interview. Brown (2003) warns the danger of such variation to fairness. OSullivan (2000) conducts an empirical study that indicated learners perform better when interviewed by a woman, regardless of the sex of the learner. Underhill (198731) expresses his concern on the unscripted flexibility means that there will be a considerable divergence between what different learners say, which come upons a test more difficult to assess with amity and reliability.Testing Speaking In PairsThere has been a shift toward a paired speakers format two assessors examine two candidates at a time. One assessor interacts with the two candidates and grade them on a global scale, while the other d oes not take part in the interaction and just assessesusing an analytic scale. The paired oral test has been used as part of large-scale, international, standardized oral proficiency tests since the late 1980s (Ildik, 2001). secern English Test (KET), Preliminary English Test (PET), outgrowth credentials in English (FCE) and Certificate in Advanced English (CAE) make use of the paired format. In a typical test, the interaction begins with a warm-up, in which the examinees introduce themselves to the interlocutor, followed by two pair interaction task. The talk whitethorn involves comparing two photographs by each candidate at first, such as in Cambridge First Certificate (Luoma, 2004), then a two-way collaborative task between the two candidates based on more photographs, artwork or computer graphics, and ends up with a multilateral discussion with the two examinees and the interlocutor about a general stem that is related to the earlier discussion.The advantages of the paired interview formatMany researchers claim that the paired format is preferable to OPI. The reasons area. The changed role of the interviewer frees up the instructors in order to pay closer attention to the production of each candidate than if they are participants themselves (Luoma, 2004).b. The reduced asymmetry allows more varied interaction patterns, which elicits a broader take of discourse and increased turn-takings than were accomplishable in the highly asymmetrical conventional interview (Taylor, 2000).c. The task type based on pair-work will generate a positive washback effect on classroom teaching and learning (Ildiko, 2001). In the case of the instructor following Communicative Language Teaching (CLT) methodology, where pair work whitethorn take up a significant portion of a class, it would be appropriate to incorporate connatural activities in the exam. In that way the exam itself is much better corporate into the fabric of the course. Students can be well-tried for pe rformance related to activities done in class. There may also be benefits in regards to student motivation. If students are aware that they will be tested on activities kindred to the ones done in class, they may have more incentive to be attentive and use class time strongly.The disadvantages of the paired interview formatThere are, however, also concerns voiced regarding the paired format.a. Mismatches between friend interactantsThe most frequently raised criticisms against the paired speaking test relate to various forms of mismatches between peer interactants (Fulcher, 2003). Ildiko (2001) points out that when a candidate has to work with an abstruse or uncomprehending peer partner, it may negatively influence the candidates performance. As a consequence, in such cases it is kind of impossible to make a valid assessment of candidates abilities.b. lack of familiarity between peer interactantsThe extent to which this testing format actually reduces the take aim of anguish of test-takers compared to other test formats remains doubtful (Fulcher, 2003). OSullivan (2002) suggests that the spontaneous support offered by a friend positively reduces anxiety and task performance under experimental conditions. However, the chances are instead high that the examinee will receive with strangers as his or her peer interactant. It is hard to imagine how these strangers can carry out some course flowing conversations. Estrangement, misinterpretation and even division may occur during their talk.c. Lack of control of the discussionProblems are generated if the examiner loses control of the oral task (Luoma, 2004). When the instructions and task materials are not clear enough to urge the discussion, the examinees conversation may go astray. Luoma (2004) points out that testers often feel ambiguous about what amount of responsibility that they should give to the examinees. Furthermore, examinees do not know what kind of performance will earn them good results w ithout the elicitation of the examiner. When one of the examinees has said too little, the examiner ought to oversee and jump in to give help when necessary.Semi-Direct Speaking TestsThe term semi-direct is engaged by Clark (197936) to describe those tests that are characterized by means of tape arrangings, printed test booklets, or other non-human elicitation procedures, rather than through face-to-face conversation with a live interlocutor. be during 1970s, and being an innovative adaptation of the traditional OPI, the semi-direct method normally follows the general structure of the OPI and makes an audio-recording of the test takers performance which is later rated by one or more trained assessors (Malone, 2000). Examples of the semi-direct type used in the U.S.A. are the simulate oral proficiency interviews (SOPI) and the Test of Spoken English 2000 (TSE) (Ferguson, 2009). Examples in U.K. include the Test in English for education Purpose (TEEP) and the Oxford-ARELS Exami nations (OLoughlin, 2001). Another mode of delivery is testing by send for as in the PhonePass test (the test mainly consists of reading sentences aloud or repeating sentences), or even video-conferencing (Ferguson, 2009).The Advantages Of The Semi-Direct Test TypeFirst, the semi-direct test is more cost efficient than direct tests, because many candidates can be tested simultaneously in large laboratories and administered by any teacher, language lab technician or auxiliary in a language science lab where the candidate hears taped questions and has their responses recorded (Malone, 2000).Second, the mode of testing is sort of flexible. It provides a practical solution in situations where it is not possible to deliver a direct test (OLoughlin, 2001), and it can be adapted to the desired level of examinee proficiency and to specific examinee age groups, backgrounds, and professions (Malone, 2000).Third, semi-direct testing represents an attempt to standardize the assessment of speaking while retaining the communicative basis of the OPI (Shohamy, 1994). It offers the alike(p) quality of interview to all examinees, and all examinees respond to the same questions so as to remove the effect that the human interlocutor will have on the candidate (Malone, 2000). The accordance of the elicitation procedure greatly increases the reliability of the test.Some empirical studies (Stansfield, 1991) show high correlations (0. 89- 0. 95) between the direct and semi-direct tests, indicating the two formats can measure the same language abilities and the SOPI can be the resembling and surrogate of the OPI. However, there are also disadvantages.The Disadvantages Of The Semi-Direct Test TypeFirst, the speaking task in semi-direct oral test is less realistic and more near than OPI (Clark, 1979 Underhill, 1987). Examinees use artificial language to respond to tape-recorded questions situations the examinee is not likely to undertake in a real-life setting (Clark, 197938 ). They may feel stressful while speaking to a microphone rather than to another person, especially if they are not accustomed to the laboratory setting (OLoughlin, 2001).Second, the communicative strategy and speech discourse elicited in these semi-direct SOPIs is quite different from that found in typical face-face interaction being more formal, less conversation-like (Shohamy, 1994). Candidates tend to use written language in tape-mediated test, more of a report or narration while, they focus more on interaction and on delivery of meanings in OPI.Third, there are often technical problems that can result in poor quality recordings or even no recording in the SOPI format (Underhill, 1987).In conclusion, one cannot assume any equating between a face-to face test and a semi-direct test (Shohamy, 1994). It may be that they are measuring different things, different constructs, so the mode of test delivery should be adopted on the basis of test purpose, accuracy unavoidableness, prac ticability, and impartiality (Shohamy, 1994). Stansfield (1991) proposes the OPI is more applicable to the placement test and evaluation test of the curriculum, while SOPI is more appropriate for large-scale test with requirement of high reliability.Marking Of Speaking TestMarking and grading is a challenge in assessing second language oral proficiency.. Since only a few elements of the speaking skill can be reachd objectively, human judgments play major roles in assessment. How to establish the valid, reliable, effective marking criteria scales and high quality scoring instruments have always been central to the performance testing of speaking (Luoma, 2004). It is important to have clear, explicit criteria to describe the performance, as it is important for raters to understand and apply these criteria, making it possible to score them consistently and reliably. For these reasons, rating and rating scales have been a central focus of research in the testing of speaking (Ferguson , 2009).Definition Of Rating ScalesA rating scale, also referred to as a scoring rubric or proficiency scale is be by Davies et al as following (see Fulcher, 2003)consisting of a series of deal or levels to which descriptions are attachedproviding an in operation(p) definition of the constructs to be thrifty in the testrequiring training for its effective operationHolistic And analytic Rating ScalesThere are different types of rating scales used for scoring speech samplings. One of the traditional and ordinarily used distinctions is between holistic and analytic rating scales. Holistic rating scales also are referred to as global rating. With these scales, the rater attempts to match the speech sample with a particular band whose descriptors specify a range of defining characteristics of speech at that level. A single score is given(p) to each speech sample each impressionistically or by being guide by a rating scale to encapsulate all the features of the sample (Bachman P almer, 1996).Analytic rating scales They consist of separate scales for different aspects of speaking ability (e.g. grammar / vocabulary pronunciation, fluency, interactional management, etc). A score is given for each aspect (or dimension), and the resulting scores may be combined in a admixture of ways to produce a composite single overall score. They include detailed guidance to raters, and bountiful information that they provide on specific strengths and weakness in examinee performance (Fulcher, 2003). Analytic scales are especially useful for diagnostic purposes and for providing a profile of competence in the different aspects of speaking ability (Ferguson, 2009). The type of scale that is selected for a particular test of speaking will depend upon the purpose of the testValidity And dependability Of Speaking TestBachman And Palmers Theories On Test expediencyThe primary purpose of a language test is to provide a measure that can be interpreted as an indicator of an indiv iduals language ability (Bachman, 1990 Bachman and Palmer, 1996). Bachman and Palmer (1996) propose that test service program including six test qualitiesreliability, construct validity, authenticity, interactiveness, impact (washback) and practicality. Their notion of usefulness can be expressed as in Figure2.3Usefulness= dependableness + Construct validity + Authenticity +Interactiveness + Impact +PracticalityThese qualities are the main criteria used to evaluate a test. Two of the qualities reliability and validity are critical for tests and are sometimes referred to as essential measurement qualities (Bachman Palmer, 199619), because they are the major justification for using test scores as a basis for making inferences or decisions (ibid). The definitions of types of validity and reliability will be presented in this section.Validity And reliablenessDefining ValidityThe quotation from AERA (American educational Research Association ) indicatesValidity is the most important consideration in test evaluation. The concept refers to the appropriateness, meaningfulness, and usefulness of the specific inferences made from test scores. Test validation is the process of accumulating read to support such inferences. A physical body of inferences may be made from scores produced by a given test, and there are many ways of accumulating evidence to support any particular inference. Validity, however, is a unitary concept. Although evidence may be put in in many ways, validity always refers to the degree to which that evidence supports the inferences that are made from the score. The inferences regarding specific uses of a test are validated, not the test itself.(AERA et al., 1985 9)Messick stresses that it is important to note that validity is a matter of degree, not all or none (MessReliability of Speaking Proficiency TestsReliability of Speaking Proficiency TestsIntroductionTesting, as a part of English teaching, is a very important procedure, not just becau se it can be a valuable source of information about the effectiveness of learning and teaching but also because it can improve teaching, and arouse the students motivation to learn. Testing oral proficiency has become one of the most important issues in language testing since the role of speaking ability has become more central in language teaching with the advent of communicative language teaching (Nakamura, 1993). However, assessing speaking is challenging (Luoma, 2004). Validity and reliability, as fundamental concerns and essential measurement qualities of the speaking test (Bachman, 1990 Bachman Palmer, 1996 Alderson et al, 1995), have aroused widespread attention. The validation of the speaking test is an important area of research in language testing.Test of oral proficiency just started in China 15 years ago, and there are a few very dominant tests. An increasing number of Chinese linguists are putting their attention and efforts on analysis of their validity and reliabilit y. Institutions began to introduce speaking tests into English exams in recent years with the widespread promotion of communicative language teaching (CLT). Publications that deal with speaking tests within institutions provide some qualitative assessments (Cai, 2002). But there is relatively little research literature relating to the reliability and validity of such measures within a university context. (Wen, 2001).The College English Department at Dalian Nationalities University (DLNU) has been selected as one of thirty-one institutions of the College English refine Demonstration Project in the Peoples republic of China. In College English (CE) course of DLNU, the speaking test is one of the four subtests of the final examination of English assessment. The examination uses two different formats. One is a semi-direct speaking test, in which examinees talk to microphones connected to computers, and have their speeches recorded for the teachers to rate afterwards. The other is a fac e-to-face interview. This research in this paper aims to ascertain the degree of the reliability and validity of the speaking tests. By analyzing the results of the research, teachers will become more aware of the validity and reliability of oral assessments, including how to improve the reliability and validity of speaking tests. I, as a language teacher, will gain insight into the operation of language proficiency test, In order to better degree of reliability and validity of a particular test, I will also take other qualities of test usefulness into account when designing the language proficiency test., such as practicality and authenticity.Research questionsThis study mainly addresses the questions of validity and reliability of the speaking test administered at DLNU. They are comprehensive concepts that involve analysis of test tasks, administration, rating criteria, examinee and testers attitudes towards the test, the effect of the test on teaching and teacher or learner attit udes towards learning the tests (Luoma, 2004). Therefore, the purpose of this study is to answer the following research questions1. Is the speaking test administered at DLNU a valid and reliable test? This question can involve the following two sub-questions1) To what extent is the speaking test administered at DLNU reliable?2) To what extent is the speaking test administered at DLNU valid?2. In what aspects and to what extent may the validity and reliability of the speaking test administered at DLNU be improved?Literature ReviewThis chapter presents a theoretical framework of speaking construct, ways of testing speaking, marking of speaking test and the reliability and validity of speaking test, also introduces the situation of speaking test in China.Analyzing Speaking And Speaking TestThe Nature Of SpeakingSpeaking, as a social and situation-based activity, is an integral part of peoples daily lives (Luoma, 2004). Testing second language speaking is often claimed to be a much more difficult undertaking than testing other second language abilities, capacities or competencies, skillsUnderhill, 1987). Assessment is difficult not only because speaking is fleeting, temporal and ephemeral, but also because of the comprehensibility of pronunciation, the special nature of spoken grammar and spoken vocabulary, as well as the interactive and social features of speaking (Luoma, 2004), because of the unpredictability and dynamic nature of language itself (Brown, 2003). To have a clear understanding of what it means to be able to speak a language, we must understand that the nature and characteristics of the spoken language differ from those of the written form (Luoma, 2004 McCarthy OKeefe, 2004 Bygate, 2001) in its grammar, syntax, lexis and discourse patterns due to the nature of spoken language.Spoken English involves reduced grammatical elements arranged into formulaic chunk expressions or utterances with less complex sentences than written texts. Spoken English bre aks the standard word order because the omitted information can be restored from the instantaneous context (McCarthy OKeefe, 2004 Luoma, 2004 Bygate, 2001 Fulcher, 2003). Spoken English contains frequent use of the vernacular, interrogatives, tails, adjacency pairs, fillers and question tags which have been interpreted as dialogue facilitators (Luoma, 2004 Carter McCarthy, 1995). The speech also contains a fair number of slips and errors such as mispronounced words, mixed sounds, and wrong words due to inattention, which is often pardoned and allowed by native speakers (Luoma, 2004). Conversations are also negotiable, unpredictable, and susceptible to social and situational context in which the talks happen (Luoma, 2004).The Importance Of Speaking TestTesting oral proficiency has become one of the most important issues in language testing since the role of speaking ability has become more central in language teaching with the advent of CLA (Nakamura, 1993). Of the four language sk ills (listening, speaking, reading, writing), listening and reading occur in the receptive mode, while speaking and writing exist in the productive mode. Understanding and absorption of received information are foundational while expression and use of acquired information demonstrate an improvement and a more advanced test of knowledge. A lot of interests now in oral testing is partly because second language teaching is more than ever directed towards the speaking and listening skillsUnderhill, 1987). Language teachers are engaged in teaching a language through speaking (Hughes, 20027). On one hand, spoken language is the focus of classroom activity. There are often other aims which the teacher might have for instance, helping the student gain awareness of practice in some aspect of linguistic knowledge (ibid). On the other hand, speaking test, as a device for assessing the learners language proficiency also functions to motivate students and reinforce their learning of language. Th is represents what Bachman (1991) has called an interface between second language acquisition (SLA) and language testing research.However, assessing speaking is challenging, because there are many factors that influence our impression of how well someone can speak a language (Luoma, 20041) as well as unpredictable or impromptu nature of the speaking interaction. The testing of speaking is difficult due to practical obstacles and theoretical challenges. Much attention has been given to how to perfect the assessment system of oral English and how to improve its validity and reliability. The communicative nature of the testing environment also remains to be considered (Hughes, 2002).The Construct Of SpeakingIntroduction To Communicative Language Ability (CLA)A clear and explicit definition of language ability is essential to language test development and use (Bachman,1990). The theory on which a language test is based determines which kind of language ability the test can measure, This type of validity is called construct validity. According to Bachman (199084), CLA can be described as consisting of both knowledge or competence and the capacity for implementing or executing that competence in appropriate, contextualized communicative language use. CLA includes three components language competence, strategic competence and pyschophysiological mechanisms. The following framework (figure 2.1) shows components of communicative language ability in communicative language use (Bachman,199085).Knowledge Structures Language CompetenceKnowledge of the world Knowledge Of LanguageStrategic CompetencePsychophysiological MechanismsContext Of SituationThis framework has been widely accepted in the field of language testing. Bachman (199084) proposes that language competence essentially refers to a set of specific knowledge components that are utilized in communication via language. It comprises organizational and pragmatic competence. Two areas of organizational knowledge that Bachman (1990) distinguishes are grammatical knowledge and textual knowledge. Grammatical knowledge comprises vocabulary, syntax, phonology and graphology, and textual knowledge, comprises cohesion and rhetorical or conversational organization. Pragmatic competence shows how utterances or sentences and texts are related to the communicative goals of language users and to the features of the langue-use setting. It includes illocutionary actsor language functions, and sociolinguistic competence, or the knowledge of the sociolinguistic conventions that govern appropriate language use in a particular culture and in varying situations in that culture (Bachman, 1987).Strategic competence refers to mastery of verbal and nonverbal strategies in facilitating communication and implementing the components of language competence. Strategic competence is demonstrated in contextualized communicative language use, such as socialcultural knowledge, real-world knowledge and mapping this onto the max imally efficient use of existing language abilities.Psychophysiological competence refers to the visual and auditory skill used to gain access to the information in the administrators instructions. Among other things, psychophysiological competence includes things like sound and light.Fulchers Construct DefinitionTo know what to assess in a speaking test is a prime concern. Fulcher (1997b) points out that the construct of speaking proficiency is incomplete. Nevertheless, there have been various attempts to reflect the underlying construct of speaking ability and to develop theoretical frameworks for defining the speaking construct. Fulchers framework (figure 2.2) (Fulcher, 2003 48) describes the speaking construct.As Fulcher (2003) points out that there are many factors that could be included in the definition of the constructPhonology the speaker must be able to articulate the words, have an understanding of the phonetic structure of the language at the level of the individual word , have an understanding of intonation, and create the physical sounds that carry meaning.Fluency and accuracy these concepts are associated with automaticity of performance and the impact on the ability of the listener to understand. Accuracy refers to the correct use of grammatical rules, structure and vocabulary in speech. Fluency has to do with the normal speed of delivery to mobilise ones language knowledge in the service of communication at relatively normal speed. The quality of speech needs to be judged in terms of the gravity of the errors made or the distance from the target forms or sounds.Strategic competence this is generally thought to refer to an ability to achieve ones communicative purpose through the deployment of a range of coping strategies. Strategic competence includes both achievement strategies and avoidance strategies. Achievement strategies contain overgeneralization/morphological creativity. Learners transfer knowledge of the language system onto lexical it ems that they do not know, for example, saying buyed instead of bought, Speakers also learn approximation learners replace an unknown word with one that is more general or they use exemplification, paraphrasing (use a synonym for the word needed), word coinage (invent a new word for an unknown word), restructuring (use different words to communicate the same message), cooperative strategies (ask for help from the listener) , code switching (take a word or phrase from the common language with the listener in order to be understood) and non-linguistic strategies (use gestures or mime, or point to objects in the surroundings to help to communicate). Avoidance or reduction strategies consist of formal avoidance (avoiding using part of the language system) and functional avoidance (avoiding topical conversation). Strategic competence includes selecting communicative goals and planning and structuring oral production so as to fulfill them.Textual knowledge competent oral interaction invol ves some knowledge of how to manage and structure discourse, for example, through appropriate turn-taking, opening and closing strategies, maintaining coherence in ones contributions and employing appropriate interactional routines such as adjacency pairs.Pragmatic and sociolinguistic knowledge effective communication requires appropriateness and the knowledge of the rules of speaking. A range of speech acts, politeness and indirectness can be used to avoid causing offence.Ways Of Testing SpeakingClark (1979) puts forward a theoretical basis to discriminate three types of speaking tests direct, semi-direct and indirect tests. Indirect tests belong to procommunicative era in language testing, in which the test takers are not actually required to speak. It has been regarded as having the least validity and reliability, while the other two formats are more widely used (OLoughlin, 2001). In this section, the characteristics, advantages and disadvantages of the direct and semi-direct tes t are presented,The Oral Proficiency Interview FormatOne of the earliest and most popular direct speaking test formats, and one that continues to exert a strong influence, is the oral proficiency interview (OPI) developed originally by the FSI (Foreign Service Institute) in the United States in the 1950s and later adopted by other government agencies. It is conducted with individual test-taker by a trained interviewer, who assesses the candidate using a global band scale (OLoughlin, 2001). It typically begins with a warm-up discussion of a few easy questions, such as getting to know each other or talking about the days events. Then the main interaction contains the pre-planned tasks, such as describing or comparing pictures, narrating from a picture series, talking about a pre-announced or examiner-selected topic, or possibly a role-play task or a reverse interview where the examinee asks question of the interviewer (Luoma. 2004). An important example of this type of test is the spe aking component of the International English Language Testing System (IELTS), which is adopted in 105 different countries around the world each year.The Advantage Of An Interview FormatThe oral interview was recognized as the most commonly used speaking test format. Fulcher (2003) suggests that it is partly because the questions used can be standardized, making comparison between test takers easier than when other task types are used. Using this method, the instructor can get a sense of the oral communicative competence of students and can overcome weakness of written exams, because the interview, unlike written exams, is flexible in that the questions can be adapted to each examinees performance, and thus the testers have more controls over what happens in the interaction (Luoma, 200435). It is also relatively easy to train raters and obtain high inter-rater reliability (Fulcher, 2003).The Disadvantage Of An Interview FormatHowever, concern and skepticism exist about whether it is possible to test other competencies or knowledge because of the nature of the discourse that the interview produces (van Lier, 1989).a. Issue of timeFor the instructor, time management can be quite an issue. For instance, using a two-hour period for exams for 20 students means each student is allowed only six minutes for testing. This includes the time needed to enter the room and adjust to the setting. With such a time limit the student and instructor can hardly have any kind of normal real-world conversation.b. Issue of asymmetrical relationshipThe asymmetrical relationship between examiners and candidates elicits a form of inauthentic and limited socio-cultural contexts (van Lier, 1989 Savignon, 1985 Yoffe, 1997). Yoffe (1997) commented on ACTFL (American Council on the Teaching of Foreign Languages) OPI that the tester and the test-taker are clearly not in equal positions (Yofee, 1997).The asymmetry is not specific to the OPI but is inherent in the notion of an interview as an e xchange wherein one person solicits information in order to arrive at a decision while the interlocutor produces what he or she perceives as most valued. The interviewee is, in most cases, acutely aware of the ramifications of the OPI rating and is, consequently, under a great deal of stress.Van Lier (1989) also challenges the validity of OPI in terms of the asymmetry between them because the candidate speaks as to a superior and is unwilling to take the initiative (van Lier, 1989). Under the unequal relationship, the speech discourse, such as turn taking, topic nomination and development, and repair strategies are all substantially different from normal conversational exchanges (see van Lier 1989).c. Issue of interviewer variationGiven the fact that the interviewer has considerable power over the examinee in an interview, concerns have been aroused about the effect of the interlocutor (examiner) on the candidates oral performance. Different interviewers vary in their approaches and attitudes toward the interview. Brown (2003) warns the danger of such variation to fairness. OSullivan (2000) conducts an empirical study that indicated learners perform better when interviewed by a woman, regardless of the sex of the learner. Underhill (198731) expresses his concern on the unscripted flexibility means that there will be a considerable divergence between what different learners say, which makes a test more difficult to assess with consistency and reliability.Testing Speaking In PairsThere has been a shift toward a paired speakers format two assessors examine two candidates at a time. One assessor interacts with the two candidates and rates them on a global scale, while the other does not take part in the interaction and just assessesusing an analytic scale. The paired oral test has been used as part of large-scale, international, standardized oral proficiency tests since the late 1980s (Ildik, 2001). Key English Test (KET), Preliminary English Test (PET), First Cer tificate in English (FCE) and Certificate in Advanced English (CAE) make use of the paired format. In a typical test, the interaction begins with a warm-up, in which the examinees introduce themselves to the interlocutor, followed by two pair interaction task. The talk may involves comparing two photographs by each candidate at first, such as in Cambridge First Certificate (Luoma, 2004), then a two-way collaborative task between the two candidates based on more photographs, artwork or computer graphics, and ends up with a three-way discussion with the two examinees and the interlocutor about a general theme that is related to the earlier discussion.The advantages of the paired interview formatMany researchers claim that the paired format is preferable to OPI. The reasons area. The changed role of the interviewer frees up the instructors in order to pay closer attention to the production of each candidate than if they are participants themselves (Luoma, 2004).b. The reduced asymmetry allows more varied interaction patterns, which elicits a broader sample of discourse and increased turn-takings than were possible in the highly asymmetrical traditional interview (Taylor, 2000).c. The task type based on pair-work will generate a positive washback effect on classroom teaching and learning (Ildiko, 2001). In the case of the instructor following Communicative Language Teaching (CLT) methodology, where pair work may take up a significant portion of a class, it would be appropriate to incorporate similar activities in the exam. In that way the exam itself is much better integrated into the fabric of the course. Students can be tested for performance related to activities done in class. There may also be benefits in regards to student motivation. If students are aware that they will be tested on activities similar to the ones done in class, they may have more incentive to be attentive and use class time effectively.The disadvantages of the paired interview formatThere a re, however, also concerns voiced regarding the paired format.a. Mismatches between peer interactantsThe most frequently raised criticisms against the paired speaking test relate to various forms of mismatches between peer interactants (Fulcher, 2003). Ildiko (2001) points out that when a candidate has to work with an incomprehensible or uncomprehending peer partner, it may negatively influence the candidates performance. As a consequence, in such cases it is quite impossible to make a valid assessment of candidates abilities.b. Lack of familiarity between peer interactantsThe extent to which this testing format actually reduces the level of anxiety of test-takers compared to other test formats remains doubtful (Fulcher, 2003). OSullivan (2002) suggests that the spontaneous support offered by a friend positively reduces anxiety and task performance under experimental conditions. However, the chances are quite high that the examinee will meet with strangers as his or her peer interac tant. It is hard to imagine how these strangers can carry out some naturally flowing conversations. Estrangement, misinterpretation and even breakdown may occur during their talk.c. Lack of control of the discussionProblems are generated if the examiner loses control of the oral task (Luoma, 2004). When the instructions and task materials are not clear enough to facilitate the discussion, the examinees conversation may go astray. Luoma (2004) points out that testers often feel uncertain about what amount of responsibility that they should give to the examinees. Furthermore, examinees do not know what kind of performance will earn them good results without the elicitation of the examiner. When one of the examinees has said too little, the examiner ought to monitor and jump in to give help when necessary.Semi-Direct Speaking TestsThe term semi-direct is employed by Clark (197936) to describe those tests that are characterized by means of tape recordings, printed test booklets, or othe r non-human elicitation procedures, rather than through face-to-face conversation with a live interlocutor. Appearing during 1970s, and being an innovative adaptation of the traditional OPI, the semi-direct method normally follows the general structure of the OPI and makes an audio-recording of the test takers performance which is later rated by one or more trained assessors (Malone, 2000). Examples of the semi-direct type used in the U.S.A. are the simulated oral proficiency interviews (SOPI) and the Test of Spoken English 2000 (TSE) (Ferguson, 2009). Examples in U.K. include the Test in English for Education Purpose (TEEP) and the Oxford-ARELS Examinations (OLoughlin, 2001). Another mode of delivery is testing by telephone as in the PhonePass test (the test mainly consists of reading sentences aloud or repeating sentences), or even video-conferencing (Ferguson, 2009).The Advantages Of The Semi-Direct Test TypeFirst, the semi-direct test is more cost efficient than direct tests, b ecause many candidates can be tested simultaneously in large laboratories and administered by any teacher, language lab technician or aide in a language laboratory where the candidate hears taped questions and has their responses recorded (Malone, 2000).Second, the mode of testing is quite flexible. It provides a practical solution in situations where it is not possible to deliver a direct test (OLoughlin, 2001), and it can be adapted to the desired level of examinee proficiency and to specific examinee age groups, backgrounds, and professions (Malone, 2000).Third, semi-direct testing represents an attempt to standardize the assessment of speaking while retaining the communicative basis of the OPI (Shohamy, 1994). It offers the same quality of interview to all examinees, and all examinees respond to the same questions so as to remove the effect that the human interlocutor will have on the candidate (Malone, 2000). The uniformity of the elicitation procedure greatly increases the rel iability of the test.Some empirical studies (Stansfield, 1991) show high correlations (0. 89- 0. 95) between the direct and semi-direct tests, indicating the two formats can measure the same language abilities and the SOPI can be the equivalent and surrogate of the OPI. However, there are also disadvantages.The Disadvantages Of The Semi-Direct Test TypeFirst, the speaking task in semi-direct oral test is less realistic and more artificial than OPI (Clark, 1979 Underhill, 1987). Examinees use artificial language to respond to tape-recorded questions situations the examinee is not likely to encounter in a real-life setting (Clark, 197938). They may feel stressful while speaking to a microphone rather than to another person, especially if they are not accustomed to the laboratory setting (OLoughlin, 2001).Second, the communicative strategy and speech discourse elicited in these semi-direct SOPIs is quite different from that found in typical face-face interaction being more formal, le ss conversation-like (Shohamy, 1994). Candidates tend to use written language in tape-mediated test, more of a report or narration while, they focus more on interaction and on delivery of meanings in OPI.Third, there are often technical problems that can result in poor quality recordings or even no recording in the SOPI format (Underhill, 1987).In conclusion, one cannot assume any equivalence between a face-to face test and a semi-direct test (Shohamy, 1994). It may be that they are measuring different things, different constructs, so the mode of test delivery should be adopted on the basis of test purpose, accuracy requirement, practicability, and impartiality (Shohamy, 1994). Stansfield (1991) proposes the OPI is more applicable to the placement test and evaluation test of the curriculum, while SOPI is more appropriate for large-scale test with requirement of high reliability.Marking Of Speaking TestMarking and scoring is a challenge in assessing second language oral proficiency.. Since only a few elements of the speaking skill can be scored objectively, human judgments play major roles in assessment. How to establish the valid, reliable, effective marking criteria scales and high quality scoring instruments have always been central to the performance testing of speaking (Luoma, 2004). It is important to have clear, explicit criteria to describe the performance, as it is important for raters to understand and apply these criteria, making it possible to score them consistently and reliably. For these reasons, rating and rating scales have been a central focus of research in the testing of speaking (Ferguson, 2009).Definition Of Rating ScalesA rating scale, also referred to as a scoring rubric or proficiency scale is defined by Davies et al as following (see Fulcher, 2003)consisting of a series of band or levels to which descriptions are attachedproviding an operational definition of the constructs to be measured in the testrequiring training for its effective operationHolistic And Analytic Rating ScalesThere are different types of rating scales used for scoring speech samples. One of the traditional and commonly used distinctions is between holistic and analytic rating scales. Holistic rating scales also are referred to as global rating. With these scales, the rater attempts to match the speech sample with a particular band whose descriptors specify a range of defining characteristics of speech at that level. A single score is given to each speech sample either impressionistically or by being guided by a rating scale to encapsulate all the features of the sample (Bachman Palmer, 1996).Analytic rating scales They consist of separate scales for different aspects of speaking ability (e.g. grammar / vocabulary pronunciation, fluency, interactional management, etc). A score is given for each aspect (or dimension), and the resulting scores may be combined in a variety of ways to produce a composite single overall score. They include detailed guidance to raters, and rich information that they provide on specific strengths and weakness in examinee performance (Fulcher, 2003). Analytic scales are particularly useful for diagnostic purposes and for providing a profile of competence in the different aspects of speaking ability (Ferguson, 2009). The type of scale that is selected for a particular test of speaking will depend upon the purpose of the testValidity And Reliability Of Speaking TestBachman And Palmers Theories On Test UsefulnessThe primary purpose of a language test is to provide a measure that can be interpreted as an indicator of an individuals language ability (Bachman, 1990 Bachman and Palmer, 1996). Bachman and Palmer (1996) propose that test usefulness including six test qualitiesreliability, construct validity, authenticity, interactiveness, impact (washback) and practicality. Their notion of usefulness can be expressed as in Figure2.3Usefulness=Reliability + Construct validity + Authenticity +Interactivene ss + Impact +PracticalityThese qualities are the main criteria used to evaluate a test. Two of the qualities reliability and validity are critical for tests and are sometimes referred to as essential measurement qualities (Bachman Palmer, 199619), because they are the major justification for using test scores as a basis for making inferences or decisions (ibid). The definitions of types of validity and reliability will be presented in this section.Validity And ReliabilityDefining ValidityThe quotation from AERA (American Educational Research Association ) indicatesValidity is the most important consideration in test evaluation. The concept refers to the appropriateness, meaningfulness, and usefulness of the specific inferences made from test scores. Test validation is the process of accumulating evidence to support such inferences. A variety of inferences may be made from scores produced by a given test, and there are many ways of accumulating evidence to support any particular i nference. Validity, however, is a unitary concept. Although evidence may be accumulated in many ways, validity always refers to the degree to which that evidence supports the inferences that are made from the score. The inferences regarding specific uses of a test are validated, not the test itself.(AERA et al., 1985 9)Messick stresses that it is important to note that validity is a matter of degree, not all or none (Mess
