The philosophy and activities of the Mathematical Problem Solving Project (MPSP) are described. The main focus is on the research and development efforts, especially the attempt to develop a conceptual framework for problem solving through the creation of an appropriate model. An extensive discussion of models of problem solving is included. Four…

This literature review focuses on determining the psychological variables related to problem solving and presents arguments for self-correcting manipulatives as a media for teaching problem solving. Ten traits are considered: attitude, debilitating anxiety, self-concept, orderliness, set, confidence, impulsive/reflective thinking, concentration…

The papers contained in this document were originally presented at the May 1978 conference on Modeling Mathematical Cognitive Development sponsored by the Models of Learning Mathematics Working Group of the Georgia Center for the Study of Learning and Teaching Mathematics. Most have been revised to reflect comments and suggestions made at the…
