Contributions of the U.S. Army Research Institute to the Training Technology Field Activity-Aberdeen.

摘要

This report summarizes ARI's efforts to develop training guidelines for improved acquisition, retention, and transfer of vehicle maintenance skills. The need for such guidelines has been documented in 10 major studies since 1964, including 4 by ARI. The results of these studies are also summarized. The studies show that performance failure rates for diagnostic, remove/replace, and adjustment tasks are very high for both novice and experienced vehicle repairers. For example, the false removal rate (good parts mistakenly removed) is about 42% of all removals. The results of the Training Technology Field Activity (TTFA) projects summarized include various recommendations and guidelines for improving the training of vehicle repairers. One set of recommendations, for example, suggested ways to immediately improve the 63W10 course at the Ordnance School. The recommendations emerged from an onsite review of the entire 16-week course given to 63W10s at Aberdeen. One set of guidelines dealt with how to produce effective vugraphs for classroom instruction. Another set derived from a review of scientific literature on training provided general principles on how to develop effective instruction principles. These results can provide a partial springboard for future research, development, and training technology transfer under a continuing TTFA program at the Ordnance school.
