A proposal for the development of geometric models in Preschool Teachers. The case of polygons

Abstract

The development of Mathematical Thinking in preschool kids is essential for them to meet the challenges of their school development; the kind of mathematical experience that they get may determine their future school performance. Unfortunately, in Chile, mathematics nursery teacher training develops in a traditional and also weak form of teaching and learning. This paper shows a viable means of knowledge building in geometry for preschool teachers, in a way that they may replicate with their own students. The research is conducted under the Socioepistemologic theory; graphical argumentation helps in the building of geometric models, in this case, polygons.
