Intelligent physiologic modeling: an application of knowledge based systems technology to medical education

This article describes the design and implementation of a knowledge-based physiologic modeling system (KPBMS) and a preliminary evaluation of its use as a learning resource within the context of an experimental medical curriculum--the Harvard New Pathway. KBPMS possesses combined numeric and qualitative simulation capabilities and can provide explanations of its knowledge and behavior. It has been implemented on a microcomputer with a user interface incorporating interactive graphics. The preliminary evaluation of KBPMS is based on anecdotal data which suggests that the system might have pedagogic potential. Much work remains to be done in enhancing and further evaluating KBPMS.
