Two questions are dealt with: (1) Can those strategies or behaviors which enable experts to solve problems well be characterized, and (2) Can students be trained to use such strategies? A problem-solving course for college students is described and the model on which the course is based is outlined in an attempt to answer these questions. The five-step model provides a guide to the problem-solving process. The stages are analysis, design, exploration, implementation, and verification. Pretest to posttest comparisons indicate that the students became more fluent at generating plausible approaches to problems. (MP)
