โœฆ Synopsis

The task of modelling a student's problem solving is intrinsically one of induction. In this paper, a further instance of induction formulated as a search is reported. A formulation of this search problem which 'contains' the Combinatorics is discussed at some length ; and several heuristics which further reduce the size of the space defined by the domain ' s rules and mal-rules are presented.

The Production Rule representation of (some) arithmetic operators is given, and the behaviour of generated models with examples is included. The paper concludes with a review of the basic assumptions made by the Modelling System, LMS, and suggestions for some extensions.

In this study a two-sample, pre/posttest, quasi-experimental design was used to investigate the effect of explicit problem-solving instruction on high school students' conceptual understanding of physics. Eight physics classes, with a total of 145 students, were randomly assigned to either a treatme
