Abstract

This paper discusses an investigation on Didactic Mediations in a situation specially built for the collaborative learning of the concept of reflection symmetry within a Dynamic Geometry software shared online. CSCL (Computer Supported Collaborative Learning), concepts of axial reflection and on learning reflection symmetry were used to construct the situation. The methodology consisted of the design of situations and experimentation with three mathematic teachers in-service training and a teacher Mediator Faculty. The chat and interactions within geometry objects were treated with a Content Analysis. Results reveal a script of activities that starts with an individual interaction with the problem, passes a session of cooperation and finish with collaborative activities in which learners take responsibility of the didactic mediations. Observation of action of the colleague or teacher in geometry environment proved to be essential to the mediation.
