Perspectivas sobre o ensino de geometria plana com livros geogebra em uma formação de professores

Abstract

This research investigates which contributions the GeoGebra book tool can bring to the teaching of Plane Geometry concepts in the continuing education of mathematics teachers. For this, an online workshop was carried out, through the Moodle environment of the Federal University of Santa Maria (UFSM), with the participation of Basic Education teachers and/or in continuing education, academics from the Graduate Program in Mathematics Education and Physics Teaching (PPGEMEF). Tasks were carried out with different approaches to geometric concepts in which the importance of organization in the construction process in GeoGebra and its reflection in the teaching of Geometry was emphasized. The instruments used in the investigation were: the questionnaire, the recording of the synchronous meeting, the task files and the discussion forum. The research performed has a qualitative approach and used Content Analysis to categorize the data obtained. Through the analysis carried out, it was concluded that the geometric concepts chosen for the productions varied around polygons and the existence of constructions in the GeoGebra books of the participants that contemplated the concept of visualization, facilitating the process of abstraction of the geometric concepts. Through the forum, in which the books were shared, the comments were permeated by observations, suggestions and praise. In this way, when analyzing the creations of the workshop participants, a plurality of materials is obtained, which, from their speeches, can bring about changes in their practice, especially when teaching Plane Geometry.
