A pilot project examined the effectiveness of computer assisted instruction (CAI) in teaching selected concepts of health and fitness: coronary risk, lifestyle, and nutrition as related to weight control. A convenience sample of 58 students from two Concepts of Health and Fitness classes were randomly assigned to two groups, both of which used Getchell's "Physical Fitness a Way of Life" (1983) as a classroom text. Each group also heard a lecture on lifestyle, using Breslow's and Enstrom's study of health habits and mortality. In addition to the text, the experimental group used three CAI programs, including activities on coronary risk, nutrition as it relates to weight control, and lifestyle. Results indicate that CAI may have had a beneficial effect in the experimental groups' performance on a test on the first textbook chapter, although no significant differences were observed between experimental and control group results on the second and third text chapters. For the first chapter, signficance may result from students spending more time on task, due to the novelty of the CAI format. A 22-item bibliography is included. (LMM)
