Computer-assisted instruction in health education: a pilot study.

This pilot study examined the effectiveness of computer-assisted instruction (CAI) in health education. Students were exposed to four PLATO (CAI mechanism) lessons and were pre- and post-tested via a cognitive examination. These results were compared to results of those students in a control group. Students in the experimental group completed evaluation questionnaires for each lesson. In addition, a cost-effectiveness study was computed for utilizing PLATO. Results indicated that (1) students enrolled in the PLATO course learned as much as the students in the Traditional course, (2) the time devoted to teaching didactic information may be reduced by a least 50 per cent, (3) students tend to prefer the use of CAI to the lecture method, and (4) departments of instruction are able to expand courses to meet the needs of those students unable to previously enroll in these classes, at no additional cost to the department of the university.
