Learning to Plan in LISP
Abstract
Protocols have been gathered of the first 30 hours of the learning of LISP. A simulation, GRAPES, has been developed that models the processes by which subjects write LISP functions to meet problem specifications. The GRAPES simulation is a goal-factored production system as specified in the ACT* theory (Anderson, 1983). The results are reported of the simulations of a number of problems and these are compared to the human protocols. GRAPES does simulate the top-down depth-first flow of control exhibited by subjects and produces code very similar to subject code. Special attention is given to modelling student solutions by analogy, how students learn from doing, and how failures of working memory affect the course of problem solving.
