The Component Based Model of the Control Knowledge in an Intelligent Tutoring Shell

Issues of pragmatics and usability motivate our starting point and perspective on developing Intelligent Tutoring Systems tool. 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 application of the component based software design methodology for realizing and arranging designing the knowledge bases and manipulating their contents for intelligent tutoring. The component based model of ITSs knowledge bases has been developed, and the concept of the control i.e. action knowledge is
