Student forgetting model: Practical experience

This paper describes student memory model applied during one semester for control of learning activities in Electrical Engineering introductory course. All assignments include tasks of 128 levels of difficulty; transitions between them are controlled by a state machine. For any level achieved by a student in one session, exponential forgetting function is applied. Two different time constants are used for theoretical tests and lab experiments. Recalculation of level, time constant, and floor is applied after any successive session. Students accepted that model quickly and analysis of results showed that it really helped to implement ldquorepetitio est mater studiorumrdquo. In the paper we describe the model in more details and provide analysis of collected data.
