THE PROBLEM SOLVING MAP METHOD: A TOOL FOR MATHEMATICAL PROBLEM SOLVING

This research paper focuses on how a novel problem solving strategy, the problem solving map (PSM) method, was taught to pupils and how they learn and use it in practice. The intention of the PSM method is to support pupils in looking for the route toward the solution. Teaching intervention was carried out during a period of six weeks. The PSM method was used in teaching the experimental group in fifteen lessons during normal school days at grade 6. The experimental group (n=17) and the control group (n=35) took part in a pre-test, post-test and 18 months later in a delayed test. The results of the tests indicated that the PSM method could be useful for teaching and learning mathematical problem solving.
