The present studies were undertaken to examine the effects of manipulating delay-interval task (Study 1) and timing of feedback (Study 2) on acquisition and retention. Participants completed a 100-item cumulative final examination, which included 50 items from each laboratory examination, plus 50 entirely new items. Acquisition and retention were…

Computerized adaptive tests (CATs) make it possible to estimate the ability of each student during the testing process. The computer presents items to students at the appropriate level, and students take different versions of the same test. Computerized testing increases the flexibility of test management in that: (1) tests are given on demand and…

A computerized adaptive test (CAT) based on the nominal response model (NR CAT) was implemented, and the performance of the NR CAT and a CAT based on the three-parameter logistic model was compared. The NR CAT produced trait estimates comparable to those of the three-parameter test. (SLD)

This paper demonstrates that an electronic tutoring program can collect data that enables a far more reliable assessment of students' skills than a standard examination. Socratic electronic homework tutor, CyberTutor can integrate effectively instruction and assessment. CyberTutor assessment has about 62 times less variance due to random test…

The goals, principles, and methods of an individualized educational assessment are described as implemented in a 12th-grade science assessment instrument undergoing field trials in Ohio. Pilot tests were planned for December 1990 and March and April 1991. The assessment design incorporates the duplex design of R. D. Bock and R. J. Mislevy (1988)…
