Formalising tutoring strategy selection in multimedia tutoring systems

摘要

Variation in tutoring strategy plays an important part in tutoring systems. The potential for providing adaptive tutoring depends initially on having a range of tutoring strategies to select from. However, in order to react effectively to the student's needs, the system not only has to be able to offer different tutoring strategies, but to choose intelligently among them and determine which is best for an individual student at a particular moment. This paper contributes a model that formalises the process of tutoring strategy selection in tutoring systems, and shows how this is deployed in a multimedia tutoring system. The evaluation of the resulting system reveals the benefits of this model in practice.
