Control knowledge and pedagogical aspects of the GET-BITS model

Abstract

The difficulty of designing and developing more useable and costeffective intelligent tutoring systems (ITSs) has caused the realization of some new approaches in that field, the realization of intelligent tutoring shells - authoring tools. Our starting point and perspective on developing ITSs shell is motivated by issues of pragmatics and usability. The paper describes pedagogical aspects and the control knowledge of the component based model of intelligent tutoring systems, called GET-BITS. The focus is on class hierarchies and design of classes for representing the pedagogical and the control knowledge in the GET-BITS model_ Distinction has been made between different modes of operation of the pedagogical module in an intelligent tutoring system (teaching, examination, and consulting), resulting in the necessity for the class hierarchies to reflect specific pedagogical knowledge structure.
