This article aims to describe a didactic situation for the teaching of Plane Analytic Geometry that was modeled and based on the Theory of Didactical Situations - TDS with the support of the software GeoGeobra in which the didactic sessions were substantiated in the theoretical model of Instrumental Orchestration - IO. In addition, we investigated the evolutionary indications of teachers' professional knowledge, taking as references authors who take into account the specificity of teaching in mathematics and who recognize the teacher's knowledge and the necessary competences for the incorporation of ICT in schools. As for the nature of the research, it is qualitative with a descriptive design. As for the data collection technique, it is an action research in which the data were collected from observation, questionnaire and video records. The participants were 12 undergraduates in Mathematics from a public University in Amazonas. The study showed that it is possible, with the help of the theoretical model of IO and having the GeoGebra software as the main resource, to apply the dialectics of TDS, promoting not only the logical-deductive development to solve problems of Plane Analytic Geometry but also professional teaching knowledge to teach mathematics.

Keywords : Instrumental orchestration; Didactic situation; Plane Analytic Geometry.
