An experimental Basic Electricity and Electronics course (BE/E) utilizing a lock-step, instructor presentation methodology was developed and evaluated at the Service School Command, Great Lakes. The study, directed toward the training of lower mental group, school nonqualified personnel, investigated comparative data on test performance, attitude, and attrition of 50 students in an experimental group matched to a control group within the ongoing individualized BE/E training system. The results revealed significantly reduced attrition within the experimental group, control group, and overall Great Lakes BE/E School with no significant differences in quality of the graduates of the two treatment groups. Attitudinal data was generally positive for both groups and not significantly different. Two factors were concluded to be responsible for the program's success: the focus of management attention to problems of training lower ability individuals in both groups, and the introduction of prestudy sessions into the experimental group. Appendixes (55 pages) include: statistical tables comparing test performance of the two groups, statistical analyses of test and attitudinal questionnaires items, instructor comments on the course, instructional materials readability and student reading ability, the prestudy concept, and cost breakdown for conducting the research.
