GeoGebra no ensino de geometria para os anos iniciais do ensino fundamental na perspectiva da BNCC: contribuições de uma formação continuada

Abstract

This research was carried out as part of the Professional Master's Program in Science and Technology Education at the Federal Technological University of Paraná, Ponta Grossa Campus, with the general objective of analyzing the contributions that an online continuing education course in the field of Mathematics could bring to elementary school teachers regarding the use of GeoGebra in Geometry teaching. To achieve this, the specific objectives were to investigate teachers' prior knowledge regarding the use of digital technologies in their pedagogical practices, develop an online continuing education course to support teachers in using GeoGebra for Geometry instruction, analyze the contributions of online continuing education for teachers in the early years of elementary school who teach Mathematics, and finally, create an educational product based on video lessons produced by the researcher, improving the continuing education course based on experiences with Basic Education teachers. In terms of its nature, this research is applied since its main characteristic is the practical application of knowledge. In terms of its focus, this research is qualitative and interpretative. Data collection took place in two stages and involved a semi-open questionnaire made available through an electronic form to the participants, as well as audio and video recordings of the continuing education sessions. The analysis was conducted with an interpretative focus, relying on the proposed theoretical and methodological framework. The research revealed that more than 70% of the participants did not have subjects related to the use of digital technologies for teaching Geometry in their initial education. Just over half did not have this opportunity in continuing education moments either. However, when offered this training, all of them expressed their interest in participating. The analysis showed that continuing education contributed to teachers' knowledge of dynamic geometry software, making them feel more prepared and confident in using this resource in Geometry teaching.
