Modeling Students Self-Studies Behaviors
In this work we propose a decision-theoretic approach to Intelligent Tutoring Systems (ITSs) that seeks to alleviate the need for extensive development and hand-tuning in the design of such systems. Given a set of available learning materials, our approach enables the ITS to track the students’ di culties and provide the right material at the right time. We model the learning process as a Partially Observable Markov Decision Process (POMDP), where the hidden information corresponds to the student’s familiarity with each of the topics to be learned. The student’s progress is monitored from his/her performance in di↵erent test exercises and, depending on this performance, the ITS actively determines which type of materials should be provided to the student. We deploy our proposed approach in a learning scenario and compare the ability of our system to model the students’ self-study behaviors of the learning materials. Our initial results show that such behaviors are not trivia...
