Open learning hypermedia, student modeling, meta cognitive skills.


In this paper we discuss the importance of incorporating into adaptive hypermedia a student model that can assess the effectiveness of a learner's exploratory behavior. We describe the details of the student model in the Adaptive Coach for Exploration (ACE), an open learning hypermedia for mathematical functions. Based on our experience of having evaluated the model with human subjects, we describe the factors such a model should incorporate to effectively provide adaptive guidance to learning through exploration for those students who cannot explore adequately on their own. We discuss how, in addition to domain dependent elements (e.g., coverage of relevant domain concepts and prior knowledge), these factors include domain independent meta-cognitive skills such as self-explanation and self-monitoring.
