The traditional CAI Computer-Assisted Instruction) system depends on the instructors who provide the course material and decide the criteria of evaluation for the students. The advanced versions we have these days have a'reactive learning environment' – where students are actively engaged in their online learning programs. The latter systems employ AI (Artificial Intelligence) tools and techniques to take students' interests and performance factors into account and proceed with tutorial dialogues accordingly. Hence, they are known as AICAI (Artificial Intelligence Computer-Assisted Instruction) System), or simply ICAI for intelligent CAI. Such AICAIs include a domain expert component (which knows all about the topic that is being taught), a student model that can analyze the responses of the learners and decode their knowledge levels as well as misconceptions, and a component which contains information on appropriate teaching strategies in different scenarios.

The main purpose of the research reported here is to show that a new and more powerful type of computer-assisted instruction (CAI), based on extensive application of artificial-intelligence (AI) techniques, is feasible, and to demonstrate some of its major capabilities. A set of computer programs was written and given the name SCHOLAR. Due to its complexity, only the conception and educational aspects of this system (including an actual on-line protocol) are presented in this paper.
