Modeling the teaching consultant

Abstract

A model of a teaching consultant is presented. The teaching consultant, an extension of the concept of a computer coach, is concerned with filling gaps in a student's knowledge base relative to a specific application. The student model used by the consultant is stored in the form of a prerequisite network, which maintains nodes of information that are connected so that prerequisite information may be readily accessed. The Teaching Consultant Model is being used as the basis for an intelligent tutoring system serving as a programming consultant for novice programmers.
