An Object-Oriented Shell for Intelligent Tutoring Lessons

Many important issues in design and implementation of ITS some functionality focuses on the way inter-object connections are represented, manipulated, and stored in the computer. However, the advancement of AI methods and techniques makes understanding of ITS 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 ITS and the educational staff is constantly widening. Acquiring and encoding this large amount of knowledge is difficult and time-consuming. We have been searching for efficient ways to do these knowledge engineering tasks. This paper describes our efforts toward developing uniform data and control structures that can be used by a wide circle of authors, e.g., domain experts, teachers, curriculum developers, etc., who are involved in the building of ITS.
