The Component Based Model of the Control Knowledge for Intelligent Tutoring

The difficulty of designing and developing more useable and cost-effective intelligent tutoring systems (ITSs) has caused the realization of some new approaches in that field, the realization of intelligent tutoring shells. Our starting point and perspective on developing ITSs shell is motivated by issues of pragmatics and usability. The advancement of AI methods and techniques makes understanding of ITSs more difficult, so that the teachers are less and less prepared to accept these systems. As a result, the gap between the researchers in the field of ITSs and the educational community is constantly widening. Also, the present ITSs need quite big development environments, huge computing resources and, in consequence, are expensive and hardly portable to personal computers. The paper describes an object-oriented model of control knowledge of the ITS shell in which the end-user (teacher) could make their own ITS lessons, alone.
