2. A simulated student-player in support of the authoring process in a knowledge-based authoring tool for educational games Maria Virvou, Konstantinos Manos Department of Informatics University of Piraeus

3. Introduction How an agent has been incorporated as an evaluation component into a knowledge-based authoring tool for educational games VR-Integate: Authoring Tool VR-Engage: Intelligent Tutoring System(ITS)

4. VR-Integate Generates ITSs that function as Virtual Reality Games The ITSs include mechanisms such as –Student Modeling –Adaptive Tutoring VR-Games are more –engaging –Motivating

5. VR-Engage An ITS with a Virtual Reality Game front end Students navigate inside a labyrinth trying to collect the “Book of Wisdom” They read new parts of the course’s theory They are tested on the course’s theory

9. Conclusions Feedback for the efficiency of the educational software can be received during the design process Students do not face possible design mistakes of the author, since these can be spotted and corrected beforehand
