RESUMO

The purpose of this work is the development of a workshop using the GeoGebra for teachers who teach mathematics in elementary education, so that they can develop their own strategies for teaching and learning with the use of this software. Therefore, the work was guided by the following research question: What guidelines are needed for an initial GeoGebras workshop, structured according to Rabardels Instrumental Genesis, enable mathematics teachers of primary school develop their own teaching and learning strategies using this software? The theoretical support searches, through the processes of instrumentation and instrumentalization, an interaction of the subjects participating in the researches with the artifact, in this case, the GeoGebra, so to turn it into an instrument. As research methodology, the Design Experiments was used; its goal is to conduct a formative evaluation to test and refine educational projects. Three workshops were held with mathematics teachers of the public schools of São Paulo, and, at the end of each workshop, the activities were analyzed and proposed changes up for the other, so as to minimize the obstacles, allowing a progressive improvement of the research process. At the end of the study, it is concluded that more important than the activities conducted were the questions made to teachers, leading them to "think about mathematics", creating and testing their hypotheses, facilitating thereby the occurrence of the Rabardels Instrumental Genesis
