Utilização do GeoGebra como proposta metodológica para auxiliar alunos da 3ª série do ensino médio na aprendizagem de cônicas

Abstract

Our work is about the use of technologies for Teaching Mathematics, that: GeoGebra. We had as objective to elaborate and analyze a didactic sequence, with the content of conical sections, for students of the 3rd year of High School, through the construction and manipulation of the geometric figures in the featured software. In order to reach our goal, we launched the identification of the theoretical discourses that point to the use of technology in the teaching of Mathematics; We elaborated a didactic sequence with the content of conic sections and analyzed the didactic sequence. A bibliographic research study was carried out, qualitative in terms of its approach and descriptive of its objectives. We searched for 28 authors, 32 works, 11 virtual sites, dated between the years 1992 and 2018. Among the main authors we use Oliveira (2013); Boyer (2010); Brazil (2006) and others. We suggest five lessons involving the content of Conics (parabola, ellipse and hyperbola). We analyze our proposal in strengths and weaknesses. It was conclusive that the study is scientifically pertinent, since there is theoretical reference in favor of the use of technologies in education. As contributions of the study, we emphasize that we reinforce the need to be closer to mathematical software of classroom reality and to encourage mathematical research in conjunction with the dynamic manipulation of its elements. Regarding the possibilities of future studies, it was pointed out the applicability of our didactic suggestions and benchmarking of their results.
