Research Abstract

In this study, we propose a new adaptive diagnostic system to identify mistakes of mathematic skills of university students; it also gives them advices to correct their mistakes. In this method, Bayesian Network is applied to model the structure of testlet items. The method makes it possible to represent paper & pencil test on computerized adaptive test (CAT).
