Multi-application player modelling and instruction provided by a knowledge-based authoring tool for educational games

This paper is about an authoring tool for Intelligent Tutoring Systems (ITS) that generates virtual reality educational games. The ITS common practice of modelling the student has been expanded to include characteristics of players such as their level of game-playing competence irrespective of the domain of the educational game. Such characteristics are domain-independent and they may affect the overall performance of a student-player. Domain-independent player characteristics are kept in user models separately from domain-dependent characteristics such as the level of knowledge of a student in a particular domain. In this way, domain-independent features may be used for modelling an individual student across many application domains and adapt advice accordingly.
