Building theories: working in a microworld and writing the mathematical notebook

Abstract : In the framework of a long term teaching experiment we present an Educational approach based on the use of a dynamic geometry software and a symbolic manipulator. Here we present the general ideas of the followed approach focusing on how meanings can originate from phenomenological experience and evolve under the guidance of the teacher. In particular we will focus on meanings related to the ideas of theory, axiom and theorem.
