Interactive Computer-Video Modules for Health Sciences Education

Abstract:

Advances in electronic image recording and computer technologyhave resulted in a remarkable increase in the power and flexibility of interactive computer-video teaching systems. The University of Washington Health Science Videodisc Development Group first demonstrated a laser videodisc controlled by a remote central computer in 1980. Even this rudimentary unit highlighted basic medical informatics principles including: rapid accessibility; a “generic” or multi-purposed format; ease of computer control; and large collections of valid, rigorously reviewed images. Advances in medical informatics have led to the development of the following previously undescribed series of teaching units:

1. The hypertext programs Hypercard, Linkway, and Guide have been used with videodiscs to develop easy-to-use instructional and reference materials. These materials demonstrate the ease with which a computer-naive instructor may develop new programs and the advantage that the intuitive nature of these programs brings to student users.

2. Patient simulations using single and double screens plus pre-defined knowledge structures;

3. Interactive single topic tutorials using preset knowledge structures;

4. A key-word-based disc searching system;

5. Electronic video microscopy;

6. A series of programs developed independently by health science faculty who have purchased multi-purpose videodiscs that demonstrate the flexibility of the multi-purpose or “generic”: collection concept.
