The friendly intelligent tutoring environment

The advancement of using the Artificial Intelligence (AI) methods and techniques in design Intelligent Tutoring Systems (ITSs) makes understanding them more difficult, so that teachers are less and less prepared to accept these systems. As a result, the gap between researchers in the field of ITSs and the educational community is constantly widening. While ITSs are becoming more common and proving to be increasingly effective, each one must still be built from scratch at a significant cost. Also present ITSs need quite big development environments, huge computing resources and, in consequence, are expensive and hardly portable to personal computers. This paper describes our efforts toward developing uniform data, explanation and control structures that can be used by a wide circle of authors who are involved in building ITSs (e.g., domain experts, teachers, curriculum developers, etc.) that is, the model of the ITSs framework, the GET-BITS model.
