    Abstrae!: In this study we explored secondary mathenzatics teachers 1 didactical deveopment of the quadratic function. This was done by analyzing a series of conceptual maps that they produced while working in groups in a teacher training program that induced them to produce three types of analysis of the mathematics subject matter: canten/, instruction and cognitive. These maps were codified using a series of a/tributes designed to describe some Aspects of their didactical knowledge. The analysis of this informal ion shows that a teacher training program, based on the didactical analysis ideas, in which teacher's work in groups, interacting with researchers and peers in arder to contras! their work, can have an impact on their visions o( the mathematics canten!.
