COACH: A tutor based on active schemas
Donald R. Gentner · Computational Intelligence · 1986
The Coach system, a computer simulation of a human tutor, was constructed with the goal of obtaining a better understanding of how a tutor interprets the student's behavior, diagnoses difficulties, and gives advice. Coach gives advice to a student who is learning a simple computer programming language. Its intelligence is based on a hierarchy of active schemas that represent the tutor's general concepts and on more specific information represented in a semantic network. The coordination of conceptually guided and data‐driven processing enables the Coach system to interpret student behavior, recognize errors, and give advice to the student.
