Uma abordagem dinâmica e inovadora para o ensino de geometria analítica no Ensino médio

Abstract

In this work, we seek to contribute to the Primary Mathematics Teaching proposing, therefore, a didactic sequence for teaching Analytic Geometry in high school. In it we bring some innovations such as the introduction of the concept of vector, and consequently show the ease afforded by this introduction on solving some classical problems of such content, and the use of a systematic program of Mathematics Dynamics: The Geogebra that will bring greater interactivity between the elements geometric and algebraic, not to mention the dynamics afforded by the use of this program making the lessons more attractive and interesting. For implementing the above objective, previously we analyzed the importance of the changes proposed in this matter, that in accordance with some theories presented in academia, as well as guidelines and recommendations made by the legislation in force in the country, compiled by several scholars in the field . Moreover, as we work with a computer program, soon became necessary to make a brief presentation of the same, but we did it in great detail to make work not too long. As a palliative measure elaborated six videos that serve as support in the use of Geogebra (Appendix D). Prepared to perform this work by classroom lecture on the subject and parallel to this, we have a description of what procedures should be done every time the class by bringing motions for exercises, animation in Geogebra and interventions that can be made by the teacher. In all classes, our main goal is to keep the student involved in the construction of concepts and maintaining a level accessible to most of them, but always raising this level gradually. However, we propose a more diversified thus providing a wider and more accurate diagnosis, it’s grounded in current theoretical and own experience.
