ExploraGraph ©- Improving interfaces to improve adaptive support

Abstract. We will present the adaptive model of the ExploraGraph © Interface and explain how the interface can serve as a mean of communication between learners and an intelligent support system. The goal of the ExploraGraph © research project was to build an environment where both user models, task model and pedagogical model could meet in a productive way. The idea was to offer each user an interface where intentions could be externalized. In it, concepts, activities and course objectives are organized in order to foster understanding, but also to project the user’s model, as in "overlay" systems but in a more expressive way. The system makes the meta-dimensions of the process naturally explicit and functional, bringing the user to learn their use and thus proceed to a higher and reflexive process level. Finally our hypothesis was that if users manipulated the interface at the level of goals and concepts, it would be easier to follow and guide them 1. The ExploraGraph © system was developed as an adaptive support environment. In the ExploraGraph © Editor, graphs of elements are dynamically and intelligentl
