Presents methodology for designing and delivering computer-assisted diagnostic tests and discusses two natural applications of this methodology: for testing purposes, and for implementing adaptive computer-assisted learning sequences based on test results. (MBR)

Investigated: (1) immediate and continuing benefits associated with using microcomputer-assisted testing with 42 biology students; (2) types of students benefiting from microcomputer-administered diagnostic testing; and (3) the feasibility of microcomputer-administered diagnostic testing. One finding is that such testing positively influences…

Approaches proposed for educational diagnostic assessment are reviewed and identified as deficit assessment and error analysis. The development of diagnostic instruments may require a reexamination of existing psychometric models and development of alternative ones. The psychometric and content demands of diagnostic assessment all but require test…

The effects of computer-based diagnostic testing on the laboratory achievement of 91 preservice elementary teachers were assessed. These teachers were enrolled in one of four laboratory sections of a general science course. Intact classes were randomly assigned to one of two treatment groups. All students completed the same laboratory activities…

In providing an alternative view to the previous article by Ward (TM 508 880), the author notes problems associated with adaptive testing, diagnostic testing, testing embedded in instruction, and testing through simulations. (BW)

Some of the benefits available from using computers to administer the kinds of tests that are familiar in educational settings are reviewed. Four applications that represent current or near-term enhancements of assessment are discussed: computerized adaptive testing, diagnostic testing, test preparation, and administration of simulations of…

Reports a study to explore student's computational performance on computer-administered testing situations while at the computer. Students from grades 3-6 (n=100) were randomly assigned to treatment order, computer assessment first or paper/pencil assessment first. Significant differences occurred in three areas: completion time, number of mental…

Describes a field test of the "Diagnostic Test of Computational Skills." Examines whether or not a computer can efficiently analyze student answers, previously unidentified computational error patterns and errors related to student use of microcomputers. Concludes that this method can be useful for immediate and accurate diagnostic information.…
