The National Board of Medical Examiners uses the Rasch model to calibrate test items, maintain item banks, equate scores, and monitor the consistency of examiner item response patterns. The model is also being used in the study of patient management problems examinations, standard-setting, and computer-based examinations. (Author/BS)

The effects of violating four item construction principles were examined to assess the validity of the principles and the importance of students' test wiseness. While flawed items were significantly less difficult than sound items, differences in item discrimination, test reliability, and concurrent validity were not observed. (Author/BW)

As a preliminary step in customizing the Stanford Achievement Test, a study was made to compare the test items at each level with the curriculum objectives of a Florida school district, classifying them as either matching, above or below grade level, or unmatching. Results are shown in table form. (TE)

In a comparison of mathematical abilities of boys and girls, after allowing for school effects, boys are seen to excel on problems involving scale or measurement, probability, and space-time relationships. Possible explanations for the observed differences are made. (Author/AV)

Where estimation of abilities in the lower half of the ability distribution for the Raven Progressive Matrices is important, or an increase in accuracy of ability estimation is needed, the multiple category latent trait estimation provides a rational procedure for realizing gains in accuracy from the use of information in wrong responses.…

Universal design of assessment has been an important step forward in making tests more accessible to students with disabilities. An issue affecting the universal design approach is the need to review individual items, potentially hundreds of them. Ideally, there would be a statistical procedure available that would first identify items that are…

The effect of an environmental field trip on student learning in one middle school in the mid-Atlantic region of the United States was examined. An experimental one-group pretest-posttest group design was implemented on a sample of 579 students which comprised 12 groups. Although a t-test for dependent samples indicated that less than half of the…

Reviewers analyzed the alignment of assessments and standards in mathematics and science from four states at a four-day institute conducted June 29 through July 2, 1998. Six reviewers compared the match between assessment items and standards in mathematics and seven compared the match in science. Data from these analyses were processed and used to…

This book draws on the analysis of national curriculum test data from more than 600 children of 10-11 and 13-14 years of age, as well as in-depth interviews with 250 of these students, as they attempt to solve test problems, in order to explore the nature of the difficulties children experience with realistic items. It is shown, by comparing test…

The purposes of this study were to test the validity of the item-pair dipolarity assumption, to change the format to avoid bipolar item pairing should the assumption prove untenable, establish a more definitive factor structure and explore its validity by relating it to other personality variables. (Author/RK)

Error in assessing learning aptitude inheres much more in the users of the tests than in the tests themselves. Assumptions fundamental to such assessment are considered. It is particularly important that the tester constantly be sensitive to the nature of the relaionship between the psychological demands of test items or tests and the learning…

Support for the concurrent validity of the scale was given when four indicators of direct dating experience were found to be significantly related to the scale scores. (Author)

This study confirmed the practical benefits of three-choice items. (Author)
