Contribuições do GeoGebra para o ensino de geometria plana com alunos do 8º ano do ensino fundamental

Abstract

Geogebra software is a technological advancement capable of facilitating the process of teaching plane geometry. The methodological resource used was bibliographic research, based on quantitative and qualitative methods. The public, subjects of the research were 8th grade elementary school students. The theme chosen for this work is justified by the need to insert technology in the classroom as a teaching strategy, in this case the GeoGebra software, as a methodological approach to teaching Mathematics, in this case plane geometry. The main objective was to investigate the contributions of Geogebra in teaching plane geometry to 8th grade elementary school students. The work is divided into three chapters. The first chapter conceptualizes the Geogebra software and its use in the classroom, highlighting the importance of the teacher encouraging students to use this teaching resource. The second chapter highlights the construction of angles of 30°, 45° and 60° using the software. Finally, the third and last chapter presents triangles and their construction through Geogebra. The field research was carried out in a municipal school, which was based on the practical use of technological resources in public school classrooms. In fact, the choice of introducing fundamental concepts through the examples presented in the work brought positive results for student learning.
