Assistance Methods of Stalled Students in a Multimedia Tutoring System by using Explanation-Based Learning and a Deductive Database

摘要

The paper describes how to assist stalled students in a multimedia tutoring system. The research on the assistance methods covers various different research fields such as intelligent Computer-Aided Instruction, machine learning on AI, knowledge databases. We will, therefore, evaluate those proposed methods from a viewpoint of the educational effectiveness, implementation feasibility, and performance. Then, we propose to use the explanation-based learning techniques and a deductive database to develop the assistance function. We call this approach the meta-level description methods of education materials. As an example, how to solve a problem of an optimizing economic functions for business is explained by our proposed meta-level description methods of educational materials.
