Generally, correlation does not suggest cause-effect relationship. 10.Please state the difference between the classroom tests and external tests.Solution:The aim of the classroom test is different from that of the external examination. External examinations are generally concerned with evaluation for the purpose of selection, the classroom test is concerned with evaluation for thepurpose of enabling teachers to increase their own effectiveness by making adjustments in their teaching to enable certain groups of students or individuals in the class to benefit more.11.Make a simple clarification on the Classical True Score Model and enumerate its demerits.Solution:The classical theory is the earliest theory of measurement. The classical theory is also referred to as the classical reliability theory because its major task is to estimate the reliability of the observed scores of a test. That is, it attempts to estimate the strength of the relationship between the observed score and the true score. It is also sometimes referred to as the true score theory because its theoretical derivations are based on a mathematical model known as the true score model. In a testing situation, we first devise a scaling rule to change a set of responses into a numerical observed score. Next we infer that the observed score faithfully reflects a true score. Finally, we infer that the true score truthfully reflects the quantity of a construct, which may or may not exit.Classical True Score Model has the following demerits: 1) the values of commonly used item statistics in test development such as item difficulty and item discrimination depend on the particular examinee samples in which they are obtained; 2) comparisons of examinees on an ability measured by a set of test items comprising a test are limited to situations in which examinees are administered the same (or parallel) test items; 3) one of the fundamental concepts, test reliability, is defined in terms of parallel forms; 4) it provides no basis for determining how an examinee might perform when confronted with a test item; 5) it presumes that the variance of errors of measurement is the same for all examinees.12.Please write five multiple-choice items on some grammatical elements (tense, agreement, etc.).Omitted.13.What is the difference between criterion referenced test and norm referenced test?Solution:Characteristically criterion-referenced tests are devised before the instruction itself is designed. The test must match teaching objectives perfectly, so that any tendency of the teacher to “teach to the test” would be permissible in that attaining objectives would thereby be assured. A criterion or cut-off score is set in advance (usually 80 to 90 percent of the total possible score), and those who do not meet the criterion are required to repeat the course.Students are not evaluated by comparison with the achievement of other students, but instead their achievement is measured with respect to the degree of their learning or mastery of the prespecified content domain.Norm-referenced or standardized tests are quite different from criterion-referenced tests in a number of respects; although, once again, some of the identical items may be used under certain conditions. By definition, a norm-referenced test must have been previously administered to a large sample of people from the target population(e.g., 1,000 or more). Acceptable standards of achievement can only be determined after the test has beendeveloped and administered. Such standards are found by reference to the mean or average score of other students from the same population.14.What is computerized adaptive testing?Solution:Adaptive testing, or computer adaptive testing, is a process of test administration in which test items are selected on the basis of the examinee’s response to previously administered items. Most commonly, such an approach would, for an examinee who experiences success with a given item, result in the purposeful presentation of an item of greaterWith each response, the computer makes a revised estimate of the examinee's ability; each revived estimate becomes more reliable. The test is terminated when the estimate reaches a specified level of reliability. We can say that computerized adaptive testing takes as its theoretical basis the Item Response Theory (IRT) or the latent trait theory, which makes the general assumption that examinee performance on a pool of test items is assumed to depend on a limited number of psychological traits called abilities. 15.What is item difficulty? How to compute item difficulty? Solution:Item difficulty is determined as the proportion of correct responses, signified by the letter “p”. The formula for item difficulty then isNCp r∑=where, p = difficulty, proportion correct,∑C r = the sum of correct responses, N = the number of examinees.16.How are item difficulty, item discriminability represented in item response theory? Solution:The idea of item difficulty as a location index will be examined first. In Figure 1, three item characteristic curves are presented on the same graph. All have the same level of discrimination but differ with respect to difficulty. The lefthand curve represents an easy item because the probability of correct response is high for low-ability examinees and approaches 1 for high-ability examinees. The center curve represents an item of medium difficulty because the probability of correct response is low at the lowest ability levels, around .5 in the middle of the ability scale and near 1 at the highest ability levels. The righthand curve represents a hard item. The probability of correct response is low for most of the ability scale and increases only when the higher ability levels are reached. Even at the highest ability level shown (+3), the probability of correct response is only .8 for the most difficult item.The concept of discrimination is illustrated in Figure 2. This figure contains three item characteristic curves having the same difficulty level but differing with respect to discrimination. The upper curve has a high level of discrimination since the curve is quite steep in the middle where the probability of correct response changes veryrapidly as ability increases. Just a short distance to the left of the middle of the curve, the probability of correct response is much less than .5, and a short distance to the right the probability is much greater than .5. The middle curve represents an item with a moderate level of discrimination. The slope of this curve is much less than the previous curve and the probability of correct response changes less dramatically than the previous curve as the ability level increases. However, the probability of correct response is near zero for the lowest-ability examinees and near 1 for the highest-ability examinees. The third curve represents an item with low discrimination. The curve has a very small slope and the probability of correct response changes slowly over the full range of abilities shown. Even at low ability levels, the probability of correct response is reasonably large, and it increases only slightly when high ability levels are reached.17.What general relationship exists between test reliability and the number of items on the test?Solution:Reliability is affected by the number of items in the test. We can readily understand how it happens that with more items in the test a greater range of scores is possible, and thus examinees are more widely dispersed along the scoring continuum. In this way it can be said that we have greater person separability and less likelihood that examinees would change rank order on repeated administrations of the test.18.What does it mean if we say a correlation coefficient is significant at the p <.05 level?Solution:“P < 0.05” means that based on the test, there is less than a 5% chance that we are wrong in rejecting the null hypothesis. And we are generally safe to say that the two variables under test are correlated.19.What are the sources of measurement errors in language test?Solution:Usually when we administer and score a test, some error of measurement is present. A variety of kinds of measurement error can introduce fluctuations in observed scores and thus reduce reliability. These different kinds of measurement error can be caused from the test-takers’ side, the scorers’ side and the administration of the test. A variety of changes may take place within the test-taker that either will introduce error on repeated administrations or will change the test-taker’s true s core from time one to time two. If true scores change, correlations between repeated sets of observed scores will go down, causing us to underestimate the reliability of the test. Temporary changes in the examinee may introduce measurement error. Influences such as fatigue, sickness, emotional disturbance, and practice effect may cause the examinee's observed score to temporarily deviate from his or her true score, or that score which reflects his or her actual ability. Subjectivity in scoring or mechanical errors in the scoring process may introduce inconsistencies in scores and produce unreliable measurement. These kinds of inconsistencies usually occur within or between the raters themselves. Inconsistencies in the administrative process may introducemeasurement error and thus reduce test reliability. This is most observable in situations where the test is administered to different groups in different locations or on different days, but may also appear within one administration in one location. 20.What is the meaning of measures of dispersion?Solution:Measures of dispersion describe how the data varies or is dispersed (spread out). The two most commonly used measures of dispersion are the range and the standard deviation. Rather than showing how data are similar, they show how data differs (its variation, spread, or dispersion).21.List five common problems at the item writing stage. Provide one example of each problem type and correct the item if necessary.Solution:1. Mixed ResponseItems are sometimes prepared to test a specific skill or competence, but close examination of the response options reveals that the options actually measure ability in skill areas other than those intended. For example: John flowers to the party last night.a) carries C) liftsb) carried d) liftedIt should be better if we have,a) carries C) is carryingb) carried d) has carried2. Length CuesFrequently the longest and most explicit option available is the obvious answer. Consider the following example:In the story, the merchant was unhappy because ita) rained. c) was windy.b) was dark. d) was windy and rainy and he had forgotten his raincoat.3. Nonsense DistractorsFor most purposes, nonsense distractors are to be avoided. Nonsense options have two basic problems. First, they tend to be weak distractors. Second, they frequently have negative “wash-back” on instruction; i.e., the students may learn errors from the examination itself. Consider the following example:They said theya. had gone. c. have went.b. had go. d. had went.Obviously distractors (b), (c), and (d) contain structures that do not occur in grammatically acceptable English for classroom use.4. Trick QuestionsFor some teachers it is always a temptation to include trick quesions on an examination. It is difficult to say whether the teacher's motive is to display cleverness, to embarrass the students for revenge, or merely to ensure test difficulty.The point is that such questions make for both inaccurate measurement and poor pedagogy. Consider the followingWhen is it not appropriate not to be absent from class?a) When you are sick.b) When you are young.c) While class is in session.d) Whenever the teacher is angry.5. Connnon Knowledge ResponsesParticularly when testing the skill of reading comprehension, it may happen that an item may test common knowledge. In this way the correct response may be chosen without comprehension of the reading passage. An example would be the following: We learn from this passage that Napoleon wasa) British c) Polishb) French d) German22.What is the essential difference between scatterplots of low-correlated variables and those of high-correlated variables? Solution:In scatterplots, if the variables are highly correlated, the dots fall very close together in a comparatively narrower or more elongated ellipse than those low-correlated variables.23.Please compute the correlation coefficient of the following item and determine whether it is significant on the level of significance of <.05? And then determine its discriminability.Solution:We compute the Pear son’s Product Moment Correlation coefficient and arrive at r=0.3007. And we do a one-tailed test with p<.05, degree of freedom being 16-1=15. And the critical value is 0.4124. But because r=0.3007<0.4124, the correlation is not statistically significant. So this item lacks a good discriminability.24.In a general proficiency test, mean=95.120, standard deviation=10.858, please compute the z-score, T-score, normal distribution area proportions of the following scores: 120, 108, 100, 95, 83, 71, 61.Solution:Raw score z-score T-score normal distribution area proportion120 2.291 72.91 98.9 108 1.186 61.86 88.22 100 0.449 54.49 67.33 95 -0.011 49.89 49.56 83 -1.116 38.84 13.22 71 -2.221 27.79 1.32 61 -3.142 18.58 0.08。

Generally, correlation does not suggest cause-effect relationship.10.Please state the difference between the classroom tests and external tests.Solution:The aim of the classroom test is different from that of the external examination. External examinations are generally concerned with evaluation for the purpose of selection, the classroom test is concerned with evaluation for thepurpose of enabling teachers to increase their own effectiveness by making adjustments in their teaching to enable certain groups of students or individuals in the class to benefit more.11.Make a simple clarification on the Classical True Score Model and enumerate its demerits.Solution:The classical theory is the earliest theory of measurement. The classical theory is also referred to as the classical reliability theory because its major task is to estimate the reliability of the observed scores of a test. That is, it attempts to estimate the strength of the relationship between the observed score and the true score. It is also sometimes referred to as the true score theory because its theoretical derivations are based on a mathematical model known as the true score model. In a testing situation, we first devise a scaling rule to change a set of responses into a numerical observed score. Next we infer that the observed score faithfully reflects a true score. Finally, we infer that the true score truthfully reflects the quantity of a construct, which may or may not exit.Classical True Score Model has the following demerits: 1) the values of commonly used item statistics in test development such as item difficulty and item discrimination depend on the particular examinee samples in which they are obtained; 2) comparisons of examinees on an ability measured by a set of test items comprising a test are limited to situations in which examinees are administered the same (or parallel) test items; 3) one of the fundamental concepts, test reliability, is defined in terms of parallel forms; 4) it provides no basis for determining how an examinee might perform when confronted with a test item; 5) it presumes that the variance of errors of measurement is the same for all examinees.12.Please write five multiple-choice items on some grammatical elements (tense, agreement, etc.).Omitted.13.What is the difference between criterion referenced test and norm referenced test?Solution:Characteristically criterion-referenced tests are devised before the instruction itself is designed. The test must match teaching objectives perfectly, so that any tendency of the teacher to “teach to the test” would be permissible in that attaining objectives would thereby be assured. A criterion or cut-off score is set in advance (usually 80 to 90 percent of the total possible score), and those who do not meet the criterion are required to repeat the course.Students are not evaluated by comparison with the achievement of other students, but instead their achievement is measured with respect to the degree of their learning or mastery of the prespecified content domain.Norm-referenced or standardized tests are quite different from criterion-referenced tests in a number of respects;although, once again, some of the identical items may be used under certain conditions. By definition, a norm-referenced test must have been previously administered to a large sample of people from the target population(e.g., 1,000 or more). Acceptable standards of achievement can only be determined after the test has beendeveloped and administered. Such standards are found by reference to the mean or average score of other students from the same population.14.What is computerized adaptive testing?Solution:Adaptive testing, or computer adaptive testing, is a process of test administration in which test items are selected on the basis of the examinee’s response to previously administered items. Most commonly, such an approach would, for an examinee who experiences success with a given item, result in the purposeful presentation of an item of greater第 10 页 共 14 页With each response, the computer makes a revised estimate of the examinee's ability; each revived estimate becomes more reliable. The test is terminated when the estimate reaches a specified level of reliability. We can say that computerized adaptive testing takes as its theoretical basis the Item Response Theory (IRT) or the latent trait theory, which makes the general assumption that examinee performance on a pool of test items is assumed to depend on a limited number of psychological traits called abilities. 15.What is item difficulty? How to compute item difficulty? Solution:Item difficulty is determined as the proportion of correct responses, signified by the letter “p”. The formula for item difficulty then isNCp r∑=where, p = difficulty, proportion correct,∑C r = the sum of correct responses, N = the number of examinees.16.How are item difficulty, item discriminability represented in item response theory? Solution:The idea of item difficulty as a location index will be examined first. In Figure 1, three item characteristic curves are presented on the same graph. All have the same level of discrimination but differ with respect to difficulty. The lefthand curve represents an easy item because the probability of correct response is high for low-ability examinees and approaches 1 for high-ability examinees. The center curve represents an item of medium difficulty because the probability of correct response is low at the lowest ability levels, around .5 in the middle of the ability scale and near 1 at the highest ability levels. The righthand curve represents a hard item. The probability of correct response is low for most of the ability scale and increases only when the higher ability levels are reached. Even at the highest ability level shown (+3), the probability of correct response is only .8 for the most difficult item.The concept of discrimination is illustrated in Figure 2. This figure contains three item characteristic curves having the same difficulty level but differing with respect to discrimination. The upper curve has a high level of discrimination since the curve is quite steep in the middle where the probability of correct response changes veryrapidly as ability increases. Just a short distance to the left of the middle of the curve, the probability of correct response is much less than .5, and a short distance to the right the probability is much greater than .5. The middle curve represents an item with a moderate level of discrimination. The slope of this curve is much less than the previous curve and the probability of correct response changes less dramatically than the previous curve as the ability level increases. However, the probability of correct response is near zero for the lowest-ability examinees and near 1 for the highest-ability examinees. The third curve represents an item with low discrimination. The curve has a very small slope and the probability of correct response changes slowly over the full range of abilities shown. Even at low ability levels, the probability of correct response is reasonably large, and it increases only slightly when high ability levels are reached.17.What general relationship exists between test reliability and the number of items on the test?Solution:Reliability is affected by the number of items in the test. We can readily understand how it happens that with more items in the test a greater range of scores is possible, and thus examinees are more widely dispersed along the scoring continuum. In this way it can be said that we have greater person separability and less likelihood that examinees would change rank order on repeated administrations of the test.18.What does it mean if we say a correlation coefficient is significant at the p <.05 level?Solution:“P < 0.05” means that based on the test, there is less than a 5% chance that we are wrong in rejecting the null hypothesis. And we are generally safe to say that the two variables under test are correlated.19.What are the sources of measurement errors in language test?Solution:Usually when we administer and score a test, some error of measurement is present. A variety of kinds of measurement error can introduce fluctuations in observed scores and thus reduce reliability. These different kinds of measurement error can be caused from the test-takers’ side, the scorers’ side and the administration of the test. A variety of changes may take place within the test-taker that either will introduce error on repeated administrations or will change the test-taker’s true s core from time one to time two. If true scores change, correlations between repeated sets of observed scores will go down, causing us to underestimate the reliability of the test. Temporary changes in the examinee may introduce measurement error. Influences such as fatigue, sickness, emotional disturbance, and practice effect may cause the examinee's observed score to temporarily deviate from his or her true score, or that score which reflects his or her actual ability. Subjectivity in scoring or mechanical errors in the scoring process may introduce inconsistencies in scores and produce unreliable measurement. These kinds of inconsistencies usually occur within or between the raters themselves. Inconsistencies in the administrative process may introduce第11 页共14 页measurement error and thus reduce test reliability. This is most observable in situations where the test is administered to different groups in different locations or on different days, but may also appear within one administration in one location.20.What is the meaning of measures of dispersion?Solution:Measures of dispersion describe how the data varies or is dispersed (spread out). The two most commonly used measures of dispersion are the range and the standard deviation. Rather than showing how data are similar, they show how data differs (its variation, spread, or dispersion).21.List five common problems at the item writing stage. Provide one example of each problem type and correct the item if necessary.Solution:1. Mixed ResponseItems are sometimes prepared to test a specific skill or competence, but close examination of the response options reveals that the options actually measure ability in skill areas other than those intended. For example: John flowers to the party last night.a) carries C) liftsb) carried d) liftedIt should be better if we have,a) carries C) is carryingb) carried d) has carried2. Length CuesFrequently the longest and most explicit option available is the obvious answer. Consider the following example:In the story, the merchant was unhappy because ita) rained. c) was windy.b) was dark. d) was windy and rainy and he had forgotten his raincoat.3. Nonsense DistractorsFor most purposes, nonsense distractors are to be avoided. Nonsense options have two basic problems. First, they tend to be weak distractors. Second, they frequently have negative “wash-back” on instruction; i.e., the students may learn errors from the examination itself. Consider the following example:They said theya. had gone. c. have went.b. had go. d. had went.Obviously distractors (b), (c), and (d) contain structures that do not occur in grammatically acceptable English for classroom use.4. Trick QuestionsFor some teachers it is always a temptation to include trick quesions on an examination. It is difficult to say whether the teacher's motive is to display cleverness, to embarrass the students for revenge, or merely to ensure test difficulty.The point is that such questions make for both inaccurate measurement and poor pedagogy. Consider the followingWhen is it not appropriate not to be absent from class?a) When you are sick.b) When you are young.c) While class is in session.d) Whenever the teacher is angry.5. Connnon Knowledge ResponsesParticularly when testing the skill of reading comprehension, it may happen that an item may test common knowledge. In this way the correct response may be chosen without comprehension of the reading passage. An example would be the following:We learn from this passage that Napoleon wasa) British c) Polishb) French d) German22.What is the essential difference between scatterplots of low-correlated variables and those of high-correlated variables?Solution:In scatterplots, if the variables are highly correlated, the dots fall very close together in a comparatively narrower or more elongated ellipse than those low-correlated variables.23.Please compute the correlation coefficient of the following item and determine whether it is significant on the level of significance of <.05? And then determine its discriminability.Solution:We compute the Pear son’s Product Moment Correlation coefficient and arrive at r=0.3007. And we do a one-tailed test with p<.05, degree of freedom being 16-1=15. And the critical value is 0.4124. But because r=0.3007<0.4124, the correlation is not statistically significant. So this item lacks a good discriminability.24.In a general proficiency test, mean=95.120, standard deviation=10.858, please compute the z-score, T-score, normal distribution area proportions of the following scores: 120, 108, 100, 95, 83, 71, 61.Solution:Raw score z-score T-score normal distribution area proportion120 2.291 72.91 98.9 108 1.186 61.86 88.22 100 0.449 54.49 67.33 95 -0.011 49.89 49.56 83 -1.116 38.84 13.22 71 -2.221 27.79 1.32 61 -3.142 18.58 0.08。
