Instrumentación de una progresión de estrategias de resolución de problemas por estudiantes para maestro

The aim of this research work is to characterize how future teachers learn to use a progression of multiple-division problem-solving strategies to interpret children’s mathematical thinking. Sixty-one teachers in training participated in a teaching experiment whose purpose was to develop the teaching competence, and to take notice of the use of mathematical thinking by children from primary education when they solve problems of division-measure with fractions. Future teachers’ learning was analyzed using the instrumental approach to characterize how they identified and interpreted the strategies used by children. The results show that teachers in training made three different uses of the progression of strategies: as an artifact, generating instrumental action schemes and implementing the progression of strategies. From these results, we took notice of arising implications for teacher training.
