A Cognitive Model of Experts' Algebraic Solving Methods
Cortes, Anibal
International Group for the Psychology of Mathematics Education, Paper presented at the 27th International Group for the Psychology of Mathematics Education Conference Held Jointly with the 25th PME-NA Conference (Honolulu, HI, Jul 13-18, 2003), v2 p253-260
We studied experts' solving methods and analyzed the nature of mathematical knowledge as well as their efficiency in algebraic calculations. We constructed a model of the experts cognitive functioning (notably teachers) in which the observed automatisms were modeled in terms of schemes and instruments. Mathematical justification of transformation rules appeared as the basis of teachers' algebraic competencies. Our research led us to consider the management of mathematical justification as a fundamental teachers' task. [For complete proceedings, see ED500859.]
