ABSTRACT

This chapter focuses on issues in representing domain knowledge and the effect that the domain knowledge has on the rest of the design of an Intelligent Tutoring System (ITS). The fields of psychology/education/human factors and computer science/AI/software engineering represent two major viewpoints involved in issues of computer-based training and ITSs. An ITS environment has two major components-a human being in the form of the student and a computer system in the form of an intelligent tutor. Cognitive psychologists look at the field of ITSs as a way of performing experiments on human cognition and learning. The term domain knowledge has been used in several ways by the various groups involved with ITSs. Domain knowledge tends to refer to the subject matter material. Declarative knowledge involves issues in representation and refers to the facts, objects, and interrelationships between objects in a domain, whereas the procedural knowledge involves issues in search and how such techniques are used to solve a particular problem.
