"Educational Evaluation and Measurement" answer

? Fifth jobs

? I. Glossary title

1, school achievement test - is the determination of the level of development of knowledge and skills of the individual after a stage of learning or training.

2, scale - is a measurement tool that attempts to determine subjective, sometimes quantitative measurement program abstract concept, characteristic variable of things may be different rules assigned numbers, thus forming different levels of measurement measurement scale, also known as the measurement scale.

3, percentile rank -? It is the most widely exported score. A raw score percentile rank refers to a group of test scores, the score is lower than the percentage of the number of scores. That is, if the test is divided into one hundred groups of grades, the number of each level is occupied by subjects percentile rank.

4, the test groups - the same master sample can be measured at the same time a number of test subjects.

Second, the short answer questions

1, the structure and characteristics of the meanings of validity.

?? A: refers to the degree construct validity is actually measured to a test to be measured and the characteristics of the theoretical structure, or it refers to a certain extent able to explain test scores structure or trait of Psychology.

?? Features: 1) size of construct validity depends primarily on the psychological traits presupposed theory.

?? 2) When the actual measured data can not confirm our hypotheses, it does not necessarily indicate that the construct validity of the test is not high, because there are no established theoretical assumptions that may occur, or the assumptions for the experimental design is not suitable inspection and so on.

? 3) Construct validity is by what measure, what evidence does not measure the accumulated give determined.

2, psychological and educational measurement functions.

? Answer: mainly in two in.

???? (a), theoretical research function. (1) to collect research data. (2) establish and test hypotheses. (3) experimental groups.

???? (b), practical applications. (1) selection of personnel. (2) personnel placement. (3) psychological diagnosis. (4) evaluation is described. (5) counseling.

3, the empirical method of determining validity.

?? A: (1) correlation method. One common method of estimating the number of correlation is calculated and measured efficiency test scores.

??? (2) distinction method. The idea is to take the test after, make them work for some time, and then divided into two groups according to the quality of work performance.

???? (3) shooting. When used as a choice quiz decisions, decisions being hit rate and overall hit rate test is a good indicator of effectiveness.

4, how to understand the relative degree of distinction.

? A: discrimination of relativity usually associated with the following aspects.

???? (1) different calculation methods, the resulting regions of different value.

???? Size (2) Effect size sample size discrimination correlation values.

??? (3) Effects of the standard packet discrimination index value (D).

???? (4) Effect of degree of homogeneity by the present sample value magnitude discrimination.

Third, the essay questions

1. Determine the norm group what issues should pay attention to.

? A: OK norm groups note the following six areas:

?? limit (1) constituting the population must be clear and must clearly illustrate the nature and characteristics of the population to be measured;

??? (2) must be a community norm of the measured representative sample of the population, to overcome the bias of sampling, using statistical sampling;

??? (3) the sampling process must be described in detail and clear in order to avoid misuse or misinterpretation of test;

??? (4) sample size should be appropriate, other things being equal, the larger the sample, the better, but it should also consider the human and material factors;

??? (5) Note norm groups of timing, must be, to be revised and updated regularly during the past;

??? (6) Note that the specific binding norm generally the norm, to obtain the maximum amount of information.

2, aptitude tests generated background.

? A: (1) support the theory

?????? In theory psychometric intelligence, the g factor proposed by Spearman given adequate attention and generally accepted, but on the substance of theoretical research and intellectual controversy has not stopped. The last general intelligence factor is subdivided into a number of basic capacity factor. Factor analysis of intelligence played a decisive role in the theory of the structure of the development process, it makes the targeted capacity factor measurement possible.

Pushing ????? (2) Practice

?????? To come to explain individual differences in the ability to be more precise sense, traditional intelligence tests is clearly not enough. With the development of society, school and professional career choices and job counseling, management and scientific personnel work becoming more common. For each person, they want to study or employment in the face of choice, a clear understanding of the extent of their own advantages and disadvantages in terms of the ability of different factors, which can determine the most effective direction of their development. All these decision-making process, the ability of the test will be one of the most important aids.

???? Since the pressing social need to be able to identify and determine the inter-individual and individual differences in the ability of different, but at that time the existing ability test - intelligence tests can not meet this requirement, at the same time, factor analysis and the general intelligence Category ability to distinguish a variety of different factors in the letter Yun is made possible aptitude test came into being. In 1941, Sutton in his theory of intelligence support, the preparation and publication of the first aptitude test battery of tests - basic mental ability test (PMA).
