Microcomputer-Based Intelligent Tutoring Systems: An Assessment.
Schaffer, John William
Computer-assisted instruction, while familiar to most teachers, has failed to become an effective self-motivating instructional tool. Developments in artificial intelligence, however, have provided new and better tools for exploring human knowledge acquisition and utilization. Expert system technology represents one of the most promising of these developments. Expert systems are computer programs that store human-like knowledge. Methods of expert system design are discussed, as are ways of computing propositional and predicate logic. "Harmony Coach" (written in Turbo Prolog) is an intelligent tutoring system that uses the microcomputer environment (IBM PC, XT, AT) to coach the specific musical tasks of writing tonal harmonic progressions, aiding the student in the creation of an acceptable harmonic sequence based on either an unfigured bass line or on a melody. It also coaches students in part-writing any previously harmonized exercises using the traditional four-part chorale model. The "Coach" is designed around the following premises, most of which are essential to any intelligent tutoring system: it must be based on sound musical precepts; it should operate in a passive role; hardware aspects should be transparent to the end user; it should use artificial intelligence whenever possible; it should embrace knowledge, explanative understanding, and problem-solving abilities; and it must run under normal restrictions of a high-end microcomputer learning environment. These precepts are explored in detail. Strengths and weaknesses of the program are discussed and a 7-item bibliography is included. (GEA)
