Abstract

A model for computer assisted mediation and its application to the field of special education for blind children is presented. The model consists of five elements: the domain model, the student model, the pedagogical model, and the dynamic and static projection of learning. The system, based on stored expert knowledge, guides the child in what he or she is able to do and able to learn. Success is dynamically evaluated in order to constantly adjust the teaching methodology. The system contrasts with previous work by giving the teacher a major role, so that the expert system, the child and the educator form a conceptual triangle. © 1997 Elsevier Science Ltd.
