A Model of Acquiring Problem Solving Expertise
This is a shortened version of a paper describing a computational model of acquiring problem solving expertise through a combination of instruction, analogical reasoning between similar problem types, and problem solving experience. In keeping with psychological studies of problem solving, expertise is defined as the possession of problem schemata which associate solution strategies with problem descriptions, supported by a specialized conceptual vocabulary for describing problems. Problem solving is described as a process of problem understanding which makes liberal use of analogical reasoning in an effort to “connect” novel problems to known solution strategies. Problem schemata and the conceptual vocabulary of which they are constructed are learned in a manner which is incremental, pragmatic, and strongly connected to existing knowledge sources.
