Abstract : The influences of the organization of a declarative knowledge base of the development and application of proceduralized knowledge was investigated in a complex troubleshooting domain. Although the two explanatory structures led to similar training performance, the two groups differed significantly in their overall level of performance in subsequent troubleshooting problems. Examination of objective measures of troubleshooting performance and think-aloud protocols indicated the breadth-first declarative knowledge representation fosters the use of mental models during problem solving in training. It also facilities proceduralization of that knowledge into fast and accurate methods for localizing faults. Keywords: Electronics; Army research.
