1 PROBLEM SOLVING VERSUS PROBLEM POSING

1.0 PROBLEM SOLVING IN MATHEMATICS 1.1 Problem Solving How to Solve It: A great discovery solves a great problem but there is a grain of discovery in the solution of any problem. Your problem may be modest; but if it challenges your curiosity and brings into play your inventive facilities, and if you solve it by your own means, you may experience the tension and enjoy the triumph of discovery.

My early problem-solving courses focused on problems amenable to solutions by Polyatype heuristics: draw a diagram, examine special cases or analogies, specialize, generalize, and so on. Over the years the courses evolved to the point where they focused less on heuristics per se and more on introducing students to fundamental ideas: the importance of mathematical reasoning and proof..., for example, and of sustained mathematical investigations (where my problems served as starting points for serious explorations, rather than tasks to be completed). a) c)
