As part of the Army's emphasis on performance-oriented instruction in training centers, a study was conducted to determine the feasibility of using self-paced instruction in a gross motor skills course. The Crawler Tractor Operator Course, a seven-week heavy equipment course conducted at Fort Leonard Wood, Missouri was selected for the study involving approximately 300 trainees. Findings indicate that in the self-pacing system, training managers can (a) train on additional pieces of equipment, if trainees are retained for the full seven weeks; or (b) achieve substantial savings in the time and training costs if the trainees are released for assignment upon their qualification in the crawler tractor operator skills. Other findings from the self-pacing study are: (a) the system permits trainees to proceed through the course at their own rate of learning, (b) the rate of learning correlates moderately with individual predictor scores, (c) the system is readily accepted by the trainees, (d) although instructor workload is heavier, motivation and morale are higher, (e) peer instruction can be used, and (f) the system is more economical and efficient. The self-paced performance tests and questionnaires used to sample trainee and instructor attitudes toward the program are appended. (Author/AJ)
