Bayesian Adaptation during Computer-Based Tests and Computer-Guided Practice Exercises.
Peer reviewed Peer reviewed
Frick, Theodore W. – Journal of Educational Computing Research, 1989
Demonstrates how Bayesian reasoning can be used to adjust the length of computer-guided practice exercises and computer-based tests to help make mastery or nonmastery decisions. Individualization of instruction is discussed, and the results of an empirical study that used the sequential probability ratio test (SPRT) are presented. (25 references)…

Computerized Adaptive Mastery Tests as Expert Systems.
Peer reviewed Peer reviewed
Frick, Theodore W. – Journal of Educational Computing Research, 1992
Discussion of expert systems and computerized adaptive tests describes two versions of EXSPRT, a new approach that combines uncertain inference in expert systems with sequential probability ratio test (SPRT) stopping rules. Results of two studies comparing EXSPRT to adaptive mastery testing based on item response theory and SPRT approaches are…
