Mathematics teachers' learning about joint work as a pedagogical practice: a praxis involving investigations with the GeoGebra software for teaching geometry
This report presents the advances of doctoral research, whose object of study is the learning of mathematics teachers about joint work as a pedagogical practice, involving investigations with the GeoGebra software, aiming at teaching geometry in the Middle School. From questioning how teachers manifest such learning in a process of continued training based on praxis, the research adopts the theoretical perspective of learning, provided by the theory of objectification, to analyze this phenomenon as the result of processes of objectification and subjectivation . Because the thesis that will result from this research is written in multipaper format, this report is divided into three parts. The first part, dedicated to the introduction, brings to light the initial concerns that motivated the investigation, the presentation of the object of study, the guiding question and the objectives to be achieved and the established methodology. In turn, the second part, composed of the chapters of the thesis, presents the first article published within the scope of the research, which systematically describes the study's literature review. Finally, the third part provides a prospective summary of the actions that will eventually be carried out to continue the research and, therefore, answer the guiding question and achieve the established objectives. Regarding the methodological aspects of the research, the recurrence of the dialectical-materialist method stands out, with the aim of monitoring, capturing and revealing the learning of five teachers who teach mathematics in a public school in the State of São Paulo, who voluntarily participated in a training process developed methodologically as a training experiment, and whose design was conceived based on the consideration of methodological references, provided by the theory of objectification, for the configuration of teaching-learning activities. Thus, the object, objectives and tasks of the activities developed in the training process are described, the way in which these activities were conducted as complex and dynamic systems and the way in which the research data were produced in the aforementioned context.
