Authoring web-based tutoring systems with WETAS
Brent Martin, Antonija Mitrović · 2003
Constraint-based modelling (CBM) is a student modelling technique for intelligent tutoring systems (ITS) that is especially suited to complex, open-ended domains. It is easier to build tutors in such domains using CBM than other common approaches. The authors present WETAS (Web-Enabled Tutor Authoring System), a tutoring engine that facilitates the rapid implementation of ITS in new domains using CBM. They describe the architecture of WETAS and give examples of two domains they have implemented. They also present the results of an evaluation of a tutoring system built using WETAS in a New Zealand school.
