Classroom use of personal computers in medical education: a practical approach.

Classroom lectures in medical schools have traditionally employed a blackboard and slides. We have developed a compact, durable, and relatively low-priced system for computer-assisted instruction which introduces audiovisual material in a random-access manner. When this system was used in the classroom to provide flexible, clinical simulations, it promoted a high level of audience-instructor interaction and facilitated problem-based learning. The system has been used successfully in lectures in our medical school, at other medical schools, at community hospitals and at national scientific meetings.
