A schema-based model for teaching problem solving. (English)
Zaslavsky, Orit, 23. Conference of the International Group for the Psychology of Mathematics Education (PME-23). Vol. 4. ,. 57-64 (1999).
In this report, we develop a model for teaching mathematical problem solving based on schema knowledge. The model makes extensive use of the graphical representation of problems to enhance students problem-solving schemas. Instruction proceeds through four successive phases: the recognition, interpretation, strategy development, and application. The design extends for about twenty-four teaching periods that spread over ten weeks. The model was field-tested in Grades five and six. The results presented in this report refer to students in Grade 5 and showed significant differences between pre-test and post-test scores in favor of the experimental group. This is an encouraging indication that the model is effective in improving students’ problem solving ability.
