Abstract

Constraint-Based Modelling (CBM) is a student modelling technique for Intelligent Tutoring Systems (ITS) that is rapidly maturing. We have implemented several tutors using CBM, and demonstrated their suitability to, in particular, open-ended domains. It is easier to build tutors in some domains (e.g. open-ended) using CBM than other common approaches. We present WETAS (Web-Enabled Tutor Authoring System), a tutoring engine that facilitates the rapid implementation of ITS in new domains. We describe the architecture of WETAS, and give examples of two domains we have implemented.
