Enhancing the instructional capabilities of intelligent tutoring systems

Abstract

This paper describes the implementation of a cognitive theory of instruction within an ITS, to enhance its instructional capabilities. The theory has been implemented as an Instructional Delivery Planner (IDP). It is based on learning functions, the psychological processes that enable learning, and teaching and learning strategies, which can activate these processes. IDP embodies a planning approach to instruction and generates individualized delivery plans, which consist of teaching and learning strategies that engage learning functions within the learner. These plans are dynamically adapted in response to new learning or to learning blockages.
