O uso do Geogebra em dispositivos móveis: uma ferramenta prática para o estudo dos vetores

Abstract

Technologies are increasingly present in people's lives and in this context mobile devices have been gaining prominence in society and consequently in the school environment. Aiming to take advantage of the technological potential of these devices used by students outside the classroom, as well as the importance of adding new technologies to the teaching-learning process, the present research had as main objective to present a study on vectors, using as didactic resource the Geogebra software developed for mobile devices. The study was developed with the students of the discipline of Vetorial Calculus and Analytical Geometry, of the Mathematics Degree course of the Federal University of Paraíba / Campus IV, in Rio Tinto - PB, arising from the students' learning difficulties in Respect to the study of vectors. In order to reach the proposed objective, the methodology used was as far as the technical procedures were the bibliographic research and the case study, as far as the objectives were the exploratory and descriptive research and as far as the approach method was used both qualitative and quantitative research. The sample consisted of twent students and the instruments used in the data collection were an activity performed with the aid of Geogebra in mobile devices and a diagnostic questionnaire, containing eleven closed questions. Regarding the results, it was possible to observe activities made with the use of pencil and paper, that the students still feel difficulties in developing the geometric reasoning of the vectors. By developing the same activities in Geogebra, students were able to bridge the algebraic and geometric treatment. At the end of the research, the students considered that the use of mobile devices in the treatment of vectors facilitated a lot of understanding of these concepts and that this methodology could also be used in other disciplines of the Degree in Mathematics.
