As contribuições do software GeoGebra para o ensino de funções quadráticas em uma turma do 1° ano do ensino médio

Abstract

This work seeks to verify the contributions of technologies in the teaching of mathematics, analyzing the use of the Geogebra software for teaching quadratic functions in a 1st year high school class, having as a problem the students' difficulty in the content of polynomial functions of the 2nd degree. This research was theoretically based on the authors Sanches and Goes (2013). To achieve the proposed objective, we divided this analysis into three stages. First, a verification of the students' learning level was carried out without using Geogebra. In the second moment, the content of quadratic functions was exactly with the use of Geogebra, seeking another point of view for the students that would help in the understanding of the content. Finally, a final learning check was performed. With the present research, it was possible to conclude that the technological tool GeoGebra, when used during classes on quadratic functions, made the content visually attractive and facilitated both student learning and teacher teaching.
