Abstract
This paper presents results from a study of the non-routine mathematical problem solving employed by 17 preservice teachers. Analysis of task-based interviews led to the
identification of five cognitive phases: engagement, transformation-formulation, implementation, evaluation, and internalisation. Corresponding metacognitive behaviours were associated with each of these cognitive phases. A five-phase model for problemsolving, which incorporates multiple pathways, is described. Since various pathways between the categories are possible, the model accommodates the range of metacognitive approaches used by students.
