Computerized Adaptive Measurement of Achievement and Ability.
Abstract
This research program was designed to investigate the applications of item response theory (IRT) and computerized adaptive testing to the unique problems of the measurement of ability and the measurement of achievement. Specific objectives relevant to these two areas were as follows: (1) to study the relative efficiency of various approaches to intersubtest branching in achievement test batteries; (2) to investigate the dimensionality of measured achievement over time; (3) to study the applicability of IRT models to the problem of mastery testing and to compare models for adaptive mastery testing with other approaches to the improvement of mastery decisions and/or reduction in test length in mastery testing; (4) to explicate the concept of Adaptive Self-Referenced Testing and to examine its applicability to the achievement testing problem; (5) to evaluate the performance of adaptive testing strategies under conditions which more reasonably represent the conditions under which these strategies might be used, and to examine the performance of adaptive testing strategies in live testing; and (6) to evaluate the utility for adaptive testing of response modes and test item formats usable in adaptive ability testing. The research utilized a combination of monte carlo simulation studies and live-testing studies.
