It often happens that software for teaching mathematics is built on data - processing models, leaving implicit the learning models that arise from the usage of the tool and that could have helped to its conception. In the back and forth game between designers and users, if the new possibilities of joint development enable the software refinement according to educational needs, it promotes as well the adaptation to human behavior already used by the tool. It is not so much in represented mathematics where we should search for learning models, but it is by turning to the interactions of the one which actions “question” software medium that “answers back”. Considering student’s conceptions and the mathematical working space that emerge from real or potential interactions, our purpose aims to put on display the mathematical work generated by the use of the tridimensional dynamic geometry software GeoGebra 3D.
