The Kuder Richardson-20 Formula is shown to be a special case, where each examinee is given sufficient time to answer each item, of a more general formula where each examinee may not be allowed the necessary time. The formula is extended to allow two scores, knowledge and speed, to be extracted from each examinees test score. Using a sample of 82…

A strategy for comparing two sets of results (one based upon early childhood recollections (ECR) and another upon video taped (VT) group behavior) from the Perceptual Characteristics Rating Scale was developed. The null distribution of the mean deviation was estimated by randomly matching an ECR response vector with a VT response vector. To…

The model developed by the Computer Based Project for the Evaluation of Media for the Handicapped in Syracuse, New York to evaluate the use of captioned films for the deaf with mentally handicapped and emotionally disturbed children is briefly described, followed by a review of recent research conducted by the project staff. Among the areas which…

This study extends previous research done on the impulsivity-reflection dimension whereby it was determined that children who are impulsive tend to report the first response that occurs to them, while reflective children delay before answering (considering the alternative solutions to problems with high response uncertainty); and that…

The effects of providing immediate knowledge of results (KR) and adaptive testing on test anxiety and test-taking motivation were investigated. Also studied was the accuracy of student perceptions of the difficulty of adaptive and conventional tests administered with or without immediate knowledge of results. Testees were 350 college students…

To determine whether placement of items on a teacher rating scale affects the factor structure underlying the scale and to determine whether changing the item format alters the ratings given, a 12-item, high-inference student rating scale was developed containing two global items pertaining to overall teacher effectiveness and 10 evaluative items…

The basic theory that the teacher style required for effective learning in the classroom is contingent on the favorableness of the group situation was tested in a controlled experiment. Eight groups of eighth-grade boys were assigned to two teachers, four groups for each. Two hypotheses were under examination: (1) A task-oriented teacher will be…

The proportionality model assumes that total testing time is proportional to the number of test items and the number of options per multiple choice test item. This assumption was examined, using test items having from two to five options. The model was not supported. (Author/GDC)

Using both the Behaviorally Anchored Rating Scales (BARS) and the Purdue University Scales, 727 undergraduates rated 32 instructors. The BARS had less halo effect, more leniency error, and lower interrater reliability. Both formats were valid. The two tests did not differ in rate discrimination or susceptibility to rating bias.

The relationship between anxiety and learning was examined within the context of drive theory and trait-state anxiety theory. Results indicated that trait anxiety had a causal influence on state anxiety and on test performance. The possibility of a reciprocal relationship between state anxiety and performance was suggested. (Author/BH)

The accuracy of estimation of the subjects' latent ability maintained by tailoring for each testee the order of item presentation and the border of item dichotomization was compared to the information provided by the original graded test items. (RC)

Effects of an applicant's information management strategy while responding to a job application item requesting illegal candidate information and moderating effects of applicant sex and position were studied for 12 hypothetical school job applicants with 108 graduate student raters. The interactions of strategy, sex, and position have important…

Over the last 15 years or so, research into measurement error has begun to consider not just whether the test items fit, but whether the people who answer the items fit. Attempts to systematically identify people who do not fit the typical pattern have led to several "person-fit statistics." This digest describes the need for such…

This study investigated the differences in disordered eating behaviors and attitudes in Japanese and American college students. The results of a 2X2 Anova revealed a significant nationality difference. American students reported more disordered eating symptoms than Japanese students (p<.01). This may be due to a convergence of biological,…

The Maryland School Performance Assessment Program (MSPAP) is a relatively new, statewide performance assessment of students in grades 3, 5, and 8. When first administered in May of 1991, the MSPAP included a battery of performance assessment tasks designed to generate written or drawn responses to reading texts. This study evaluated selected…
