As part of a larger program to determine which Navy skills can be learned by lower aptitude personnel, and which methods and techniques would be most effective, an experimental course in printed circuit board soldering was given to 186 Group IV students in 13 classes. Two different training approaches--one stressing instructor guidance and the other featuring a film viewer device--were evaluated. Data were obtained using questionnaires and both performance and paper and pencil tests. Group IV soldering efficiency was compared with that of experienced Navy technicians. In addition, tests measuring transfer of skills learned in the course were constructed and administered to selected classes. Major findings were: (1) Group IV personnel succeeded in learning the rather exacting skills required, but needed a much longer training period than other personnel; (2) the film viewer approach proved to be an effective alternative to conventional methods, and was preferred by the Group IV trainees. Recommendations for implementation of findings were made, and research projects--both current and planned--were briefly discussed. (Two references and ten tables and figures are included.) (Author/LY)
