The Effects of Expert Systems Training versus Content-Based Training on the Troubleshooting Achievement of Onan Corporation Service Personnel. Training and Development Research Center, Project Number Forty-Eight.
Westerdahl, Edward John
This study compared the effectiveness and efficiency of trainees in the Onan small products gasoline course under two training curricula: (1) the control group curriculum was the in-place course on the Emerald generator set; and (2) the experimental group curriculum was essentially the same with the addition of one lesson based on methods used by experts in solving complex troubleshooting problems and some of the procedures that the experts had developed for themselves, and the substitution of a second lesson which added the use of a problem space map. The study focused on ways of presenting material in a cohesive program that would help students understand and troubleshoot electrical/electronic circuits. Both groups received a pretest on the course material and were tested again after the instruction was completed. Results indicated that if novices are given information on troubleshooting methods and how to use them, they will be able to solve a given problem faster than other novices not given this information. It is concluded that further research is necessary to determine whether the troubleshooting knowledge or troubleshooting procedures had more influence on the ability of the experimental group to perform a troubleshooting task. Appendices contain questionnaires, consent forms, achievement tests, treatment outlines, and troubleshooting protocols. (42 references) (DB)
