Training Maintenance Technicians for Troubleshooting: Two Experiments with Computer Simulations

Abstract
Aviation maintenance trainees participated in two experiments designed to assess the relative effectiveness of traditional instruction versus two types of computer simulation in the context of aircraft power-plant troubleshooting. Simulations ranged in nature from abstract, context-free problems to those involving specific aircraft power plants. Traditional instruction included reading assignments, television programs tailored to aircraft power-plant troubleshooting, and on-line quizzes. The first experiment compared the three training methods, and the second considered a mixture of the two computer simulations versus traditional instruction. The primary conclusion was that an appropriate combination of low- and moderate-fidelity computer simulations can provide sufficient problem-solving experience to be competitive with the more traditional lectureldemonstration form of instruction.
