A utilização do Software Geogebra como ferramenta para o ensino de vetores no curso de Licenciatura em Matemática

Abstract

The purpose of this article is to investigate the potential of the GeoGebra Software for teaching vectors in the Mathematics Degree course. To reach this objective, the following paths were traced: to make a description about GeoGebra software; explore semiotic representations of vectors in GeoGebra software and finally analyze the development and perception of students in a didactic sequence using GeoGebra. In order to apply this didactic sequence, a field research was carried out at the Federal Institution located in the south of Piauí, with students from the third module of the Mathematics Degree course, through a pre-questionnaire, a pedagogical intervention and a post-questionnaire. In the Pre-Questionnaire, it was observed that most students had mastered the content that addressed the questions. In the pedagogical intervention, a class with vector content was carried out with the help of GeoGebra software to make an interrelation with the theory of semiotic representation registers. In the Post-Questionnaire, it was observed that students performed well, which shows that they understood the content of vectors. To solve some problems they used the conversion model. During the research it was noticed that the use of the GeoGebra software in the teaching of vectors contributed to the students' learning. Because through it was possible to approach the two models of the Theory of Registers of Semiotic Representation: treatments and conversions
