This Note, reprinted from the Journal of Educational Technology Systems, v. 15, no. 3, 1986-1987, describes an intelligent tutor for basic algebra. A main goal of the project is to develop a computer tutoring system with skills and knowledge approximating those of a high-quality human tutor. In particular, it is exploring novel learning opportunities that can be made available to students for the first time by exploiting the reactive capabilities of such intelligent tutors. In this context, the authors focus on the role of an algebra expert system embedded in the tutor. They discuss how it can be used to help students learn several nontraditional types of skills and knowledge in the context of algebra, including goal-directed reasoning skills and debugging techniques.
