A prescriptive model of problem-solving performance is described. The aim of the model is to specify explicitly how problems should be described initially in such a form as to facilitate their subsequent solution. According to the model, the process of initial problem description can be decomposed into two successive stages. The first uses general…

Discusses some central ideas emerging from a systematic approach to teaching scientific problem-solving skills. Areas considered include: insights derived from naturalistic studies; effective problem-solving methods; problem-solving procedures; characteristics of the knowledge base (focusing on functional conceptual building blocks, knowledge…

A theoretical model specifying the underlying knowledge and procedures whereby human subjects can generate effective initial descriptions of scientific problems was formulated. The model is prescriptive since it does not necessarily try to simulate the behavior of actual experts nor assume that their performance is optimal. The model, elaborated…

Several central ideas emerging from a systematic approach to teaching problem-solving in the quantitative sciences (chemistry, physics, engineering) are discussed. Areas addressed include: differences between teaching and performance, between naturalistic and effective functioning, and between detailed observations and gross statistical data;…
