We are developing a computer system to teach medical students and residents the art of listening to the heart for diagnostic clues, known as cardiac auscultation. The Cardiac Auscultation Diagnosis Instruction (CADI) system is designed to teach students both the clinical reasoning needed for effective diagnosis, and the perceptual skills needed for listening to the peculiar sounds of the human heart. Currently, learning auscultation is difficult because it requires students to visualize complex, dynamic structures as they are described by an instructor, and to focus on clinically important sounds in a sonic morass. The CADI environment will provide a realistic setting in which students "learn by doing". Furthermore, the environment will provide support for beginning students while still providing a demanding test for more advanced users. We believe that the computer's multimedia capabilities, together with intelligent tutoring principles grounded in cognitive theory, can help medical students master the challenging skill of auscultation. CADI's design draws on earlier work in case-based reasoning and goal-based scenarios, and their combination in the case-based teaching architecture.
