Student and instructor models: Two kinds of user model and their interaction in an ITS authoring tool

Abstract

WEAR is a Web-based authoring tool for Intelligent Tutoring Systems in Algebra related domains. Apart from modelling the student which is a common practice in almost all ITSs and ITS authoring tools, WEAR deals also with modelling the other class of its users: the instructors. Student and instructor models in WEAR interact with each other by exchanging information. This is in favour of both classes of WEAR's users, since they are affected by each other in a way similar to the one in a real educational setting. This paper describes the two kinds of user model and the type of information that they exchange. The issues raised in this research may be applied to other authoring t ools by the addition of an instructor modelling component. © Springer-Verlag Berlin Heidelberg 2001.
