On the dynamics of learner models
Ana Paiva, John A. Self, Roger T. Hartley · 1994
. In order for interactive learning environments to enrich and individualize the communication with learners, they use learner models, which can be seen as explicit representations in the system of some characteristics of that particular learner. These explicit learner models are created during the interaction with the learner andbasedon the actions performed byhim or her. The created content of the model will then influence the interaction to be established with that same learner. So, on the one hand, these models are created based on the knowledge interchange between the system and the learner; and, on the other hand, the knowledge interchange between the two may dependon the content of that model. This makes learner modeling a very dynamic process. This dynamic feature of learner models is explored in this document by analyzing the mechanisms of change in learner models and its relation with the behavior of the learner. We define two types of changes: system and learner changes. Fi...
