Reckase, Mark D.; Hirsch, Thomas M. – 1991
This paper addresses the problem of whether two-dimensional solutions with different apparent meanings and different implied interpretations of the number-correct scale could be produced from the same test data set by simply shifting the orientation of the two-dimensional projection plane. An artificial data set of 3,000 response vectors and a…

Verschaffel, Lieven; And Others – Journal of Educational Psychology, 1992
To test the Lewis and Mayer simulation model (1987) for understanding compare problems, 3 experiments involving 39 college students and 15 third graders used registration of eye movements. Two experiments somewhat support the model, suggesting it holds true only when the task puts cognitive demands on the subject. (SLD)

Spray, Judith A.; Reckase, Mark D. – 1994
The issue of test-item selection in support of decision making in adaptive testing is considered. The number of items needed to make a decision is compared for two approaches: selecting items from an item pool that are most informative at the decision point or selecting items that are most informative at the examinee's ability level. The first…

Miller, Timothy R. – 1991
Two studies were carried out to evaluate the quality of multidimensional item response theory (MIRT) model parameter estimates obtained from the computer program NOHARM. The purpose of the first study was to compute empirical estimates of the standard errors of the parameters. In addition, the parameter estimates were evaluated for bias and the…
