Abstract

This paper describes a fully operational intelligent tutoring system which incorporates artificial intelligence techniques to produce a computer aided instruction system for computer configuration and troubleshooting in the domain of education, Much of its logical or infer encing capabilities are derived from human expert in conjunction with uses of simulation models. The system also includes a high tuned structure for allowing students to communicate through a natural language dialogue and colour graphics. Although the system is extremely large, it is sufficiently fast to be exercised in a training or classroom environment. The system goes through three phases: teaching phase, diagnostic phase, and evaluation phase. It is devolped to be a step for improving the quality of education at low cost and to overcome the problems in existing approaches. It is divided into modules, each one contains a collection of PROLOG programs and produces several windows and about 150 colour screens. Students were considered as a model to be a major thrust in the system. Experiments had been carried out to study the effectiveness of the system and the iprovements in the aca- demic achievement of students. Results concluded the positive effect of the system where the experimental groups, which used the computer aided educational expert technique, had significantly greater gains than the control groups, which used traditional techniques, and had poor progress.
