An evaluation agent that simulates students’ behavior in Intelligent Tutoring Systems Maria Virvou, Konstantinos Manos, George Katsiwnis Department of Informatics University of Piraeus
Introduction • Risk – Free Evaluation!
Evaluation Agent’s Reasoning • Purpose: Simulate a student in an ITS • Needed Material: A student’s digital image • Temperamental Model: Student’s reaction in the VR-Environment of the ITS • Cognitive Model: Student’s mental capabilities and knowledge level of the domain
Temperamental Model • The student’s behavior is related to the way s/he plays the educational game in the virtual world • In the game, one must fight one’s way through using one’s knowledge
Temperamental Data • The way a user walks around the virtual world • Familiarity with the computer • Time to answer a question (speed) • Pausing time after response (surprise) • Corrections before answer (certainty) • Unclear mouse moves (concentration) • Determination Speed + Certainty
Cognitive Model • The level of student’s knowledge • The student’s retention capabilities • Cause of error(typographic,spelling…) • Ebbinghaus Forgetting Model

Conclusions • Both Temperamental and Cognitive data are used to simulate students • 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
