Object-Oriented Architecture for Intelligent Tutoring Systems

摘要

This report describes an object oriented architecture for intelligent tutoring systems, oriented around objects that represent the knowledge elements to be taught by the tutor. Each of these knowledge elements, called bites inherits both a knowledge organization describing the kind of knowledge represented and tutoring components that provide the functionality to accomplish standard tutoring tasks like diagnosis, student modeling, and task selection. We illustrate the approach with several tutors implemented at the Learning Research and Development Center.
