Abstract
The Pathophysiology Tutor (PPT) is intended to assist students to integrate their knowledge of cardiovascular physiology and to learn to apply it to solve pathophysiology problems using a hypothetico-deductive reasoning process.
While PPT is not yet a "smart tutor", it incorporates a number of features of such programs. It is implemented in Turbo-PROLOG using a rule-based formalism. Tutoring rules are distinct from the cardiovascular knowledge base. The user interface employs menus and simple keystroke entries and output text is obtained from stored text files. The tutoring rules incorporate a primitive student model based on eight years experience using these same pathophysiology problems in small group tutorials.
The lack of natural language inputs has not proven to be a serious limitation, although the inability of generate text outputs does significantly limit the extent to which individualized tutoring can be provided. Nevertheless, the PPT is a valuable first step towards the development of a "smart tutor".
