Trigonometria em ação para o ensino fundamental: uma abordagem aplicada que facilita a compreensão das relações trigonométricas básica

Abstract

This article discusses an experiment in teaching Trigonometry, developed with the goal of engaging students in the search for associations of some mathematical models to practical situations. Possessing central theme trigonometry in action for primary education: an applied approach that facilitates the understanding of the basic Trigonometric relations. Trigonometry is the mathematical content of paramount importance to the student because it has great relevance within the studies related to mathematical principles. Given this factor, we made a case study in the School of Education State Center Lucas Coelho, located in Benedito Leite, Maranhão state, in a class of 9th grade of elementary school along with the mathematics teacher of that school, where we used some decisive and able to revert a picture of disinterest of most of the students on Trigonometry mechanisms. The first step was the historical work, the concepts and basics of content, such as sine, cosine and tangent in right-angled triangle, and its applications in everyday life through practical activities outside the classroom. This case study sought to describe the use of methodological actions that incorporate experiments and measuring instruments can contribute to the learning of trigonometry from the perspective of study. At the end of the survey it was noticed that the classes are of great value to the process of teaching and learning, since the vast majority of students stated that they had an easier time understanding the content and make resolving issues after the practice session
