This study applied the mode of on-the-fly assembled multistage adaptive testing to cognitive diagnosis (CD-OMST). Several and several module assembly methods for CD-OMST were proposed and compared in terms of measurement precision, test security, and constrain management. The module assembly methods in the study included the maximum priority index…

Computerized adaptive testing (CAT) and multistage testing (MST) have become two of the most popular modes in large-scale computer-based sequential testing. Though most designs of CAT and MST exhibit strength and weakness in recent large-scale implementations, there is no simple answer to the question of which design is better because different…

The impact of computerized adaptive test (CAT) administration formats on student performance was studied with 645 medical technology students who also took a paper-and-pencil test. Analysis of covariance indicates no significant interactions among test administration formats and provides evidence for adjusting CAT test to more familiar modalities.…

Findings of studies examining the effects of presentation media on item characteristics are reviewed. The effect of medium of presentation independent of adaptive methodology in computer-assisted testing was studied through tests of 763 Marine trainees. Conditions necessary for score equivalence between item presentation media are described. (SLD)

Performance of 156 undergraduate and 48 graduate students on a self-adapted test (SFAT)--students choose the difficulty level of their test items--was compared with performance on a computer-adapted test (CAT). Those taking the SFAT obtained higher ability scores and reported lower posttest state anxiety than did CAT takers. (SLD)
