Enhancing modelling of users’ strategies in exploratory learning through case-base maintenance

Abstract. Exploratory learning allows learners to solve a problem using different strategies. However, only a limited number of these strategies is known in advance and can be introduced by the designer and/or teacher. In previous work we have proposed a case-based knowledge representation, modelling the learner behaviour as simple cases and collection of cases (i.e. strategies). In this paper we enhance this approach through case-base maintenance with mechanisms that identify and store inefficient cases (i.e. cases that pose additional difficulty to the learning process), and enrich the case-base by adding new strategies. Key words: case-based reasoning, case maintenance, exploratory learning environments, user modelling 1
