Analysis of Fidelity Requirements for Electronic Equipment Maintenance
Abstract
The purpose of this study was to determined the transfer of training to actual equipment derived from training on modified printed circuit boards with varying numbers of simulated test points represented photographically and in three dimensions. The problem addressed was how much fidelity is required to achieve desired training effects. Subjects in the experimental phases were 99 Navy recruits in Electronic Technician Splice Modules 30 - 34 of the Basic Electricity and Electronics school at Orlando Naval Training Center. Students were classified as high medium or low proficiency based on completion time of the previous self-paced course modules. A three-way analysis of variance design was used for the main independent variables of fidelity (three-dimensional vs two-dimensional boards), three levels of test point availability (100%, 67%, 33%), and three trainee proficiency levels. Three different circuit boards were utilized in the study; and FM Radio First IF Amplifier board, FM Radio Second IF Amplifier board and a Power Supply board. Each had three fault group types. The dependent variables were number of test points probed, time to probe, and number of trips to the learning supervisor before fault localization. The results indicated no significant differences when comparing the experimental treatments to the control group. The control group trained on unmodified boards tended to have an equal or higher number of probes, and equal or more probe time during testing than the students trained on lower fidelity boards. The control group trained on unmodified boards did not have a significantly higher troubleshooting success rate than students trained on modified boards.
