The present project continuous work began under a previous project, Knowledge-based revision of cognitive procedures in response to changing task demands Toward a theory of the nature and function of principled knowledge. In the course of the previous project, a theory of skill acquisition was developed. The basic principles of this theory are that 1 skill acquisition consists of encoding the results of problem solving for future use, and 2 that skill acquisition consists of the correction of errors, where an error is defined as a contradiction between the outcomes of problem solving steps and prior domain knowledge. The theory was embodied in a simulation model called the Heuristic Searcher HS. The HS model was used to clarify various phenomena in the learning of elementary arithmetic.
