TOOLS FOR FOSTERING AND GUIDING THE STATISTICS TEACHERS' REFLECTION ON THEIR OWN PRACTICE

摘要

Teachers need to reflect on their own mathematical practices and on the teaching and learning processes experienced to acquire and adapt their didactical knowledge. Nevertheless, this didactical analysis and reflection requires of the mastering and application of adequate conceptual and methodological tools. In this paper we present a model for the statistical and didactical training of teachers that has resulted from our experience as mathematics educator, and is based on the application of the "onto-semiotic approach" to mathematical knowledge and instruction. We also apply a set of "guidelines for didactical analysis", based on our theoretical framework, to design, implement and assess a teaching and learning process about statistics with a group of student teachers.
