Procedures are presented for equating simultaneously several tests which have been calibrated by the Rasch Model. Three multiple test equating designs are described. A Full Matrix Design equates each test to all others. A Chain Design links tests sequentially. A Vector Design equates one test to each of the other tests. For each design, the Rasch…

The literature on criterion referenced testing is full of discussions concerning whether classical measurement techniques are appropriate, whether variance is necessary, whether new indices of reliability are needed, and the like. What appears to be lacking, however, is a clear and simple discussion of why the problems occur. This paper suggests…

The purposes of this study were to determine the relationship between item readability and item difficulty in a standardized mathematics achievement test, and to determine if students could raise their mathematics achievement scores if they were given aid in reading items that presented them with reading difficulty. Two hundred third and fourth…

An item analysis of the Stanford Achievement Test performance of about 12,000 students in schools and classes for the hearing impaired is presented. Tables show the percentage of correct answers to each question, as well as a summary of the responses for each sub-test and major categories within some sub-tests. Because the test was developed for…

The objective of the inquiry was to develop a psychological instrument for use in assessing the attitudes held by secondary school and college students. For reliability purposes, it was deemed that a minimum of 30 or more semantic scales, used as individual items would be essential. A seven position ordinal scale was interposed between each pair…

An experimental test for achievement motivation which consists of 100 pictures of imaginary figures called gumpgookies was tested on Head Start children. On each picture, two gumpgookies are presented in a semi-structured situation, each engaged in behaviors that reflect different degrees of motivation to achieve. The child being tested is asked…

Assertive behavior in children is characterized as manipulation and exploration of the environment. Assertive behavior can be nondestructive or destructive. It has been suggested that learning is dependent on assertion and that distortion or inhibition of assertive behavior may restrict or distort the learning process. Fifty Head Start children…

This study analyzes the Object Categorization Test (OCT) and the Picture Categorization Test (PCT) to provide (1) psychometric analysis of the tests, (2) substantive analysis detailing variation in performance level as a function of age, race, class, and sex, and (3) normative data yielding frequencies of various score patterns. Data was taken…

A wealth of instructional information is intrinsic to standardized achievement tests. Most practioners fail to realize the availability or potential of item analysis information or are unable to utilize such information appropriately. Achievement tests have not fully accomplished their purposes if the information derived stops at just test scores…

Empirical results are presented as regards the implementation of a latent-trait psychometric model by means of conditional maximum likelihood estimation. Items are scored polychotomously into varying numbers of nominal categories and the test and item characteristic curves and information functions are examined. It is concluded that scoring items…

Sixty subjects participated in an experiment involving estimation of difficulty of items in a test of reasoning ability. The estimates were to be given both according to conventional conditions of magnitude estimations with a preassigned comparison standard and according to a modified procedure of magnitude estimation where the comparison standard…

This study examined the nature of reading comprehension to determine if the process is best described as a unitary ability or in terms of multiple skills that can be identified and measured. Test items were constructed to measure each of the comprehension skills selected for investigation: (1) remembering word meanings, (2) inferring word meanings…

Five-hundred dichotomously scored response patterns were generated with sequentially independent (SI) items and 500 with dependent (SD) items for each of thirty-six combinations of sampling parameters (i.e., three test lengths, three sample sizes, and four item difficulty distributions). KR-20, KR-21, and Split-Half (S-H) reliabilities were…

Four new methods of item analysis were used to select subsets of items which would yield measures of attitude change. The sample consisted of 263 students at Michigan State University who were tested on the Inventory of Beliefs as freshmen and retested on the same instrument as juniors. Item change scores and total change scores were computed for…

Several samples of Black and White students were drawn from the 1970 PSAT administration in Georgia and studied for item x race interaction on both the verbal and mathematical sections of the test. When subsamples of candidates were drawn from their respective racial groups, matched on mathematical for the study of verbal items and matched on…
