This work presents a model for student knowledge diagnosis that can be used in ITSs for student model update. The diagnosis is accomplished through Computerized Adaptive Testing (CAT). CATs are assessment tools with theoretical background. They use an underlying psychometric theory, the Item Response Theory (IRT), for question selection, student knowledge estimation and test finalization. In principle,...
In a computer-adaptive test (CAT), learners are not usually allowed to revise previously entered responses.

Findings from this study showed that the ability to modify previously...
