Uma proposta de ensino das razões trigonométricas no triângulo retângulo com auxílio de material concreto e jogos digitais

Abstract

The challenges of Brazilian public education are well known, however the focus of this research is mathematics education which is a point to be considered, as mathematics has a high rate of failure in public education. In view of this issue, this work seeks a bias of an active methodology that has as main actors the students in search of knowledge with the support of concrete materials, always seeking to make the mathematical subject possible working with the reality of the students in order to awaken the creativity and student interest. But how will the development of this research be? A priori, it will be worked with the mathematical subject: trigonometry in the right triangle with the students of the 9th year of elementary school of the José Gonçalo Pereira school, this subject will be developed with the support of the Trigonometric domino and the Wordwall digital platform, in which both tools work on the concepts of trigonometry in the right triangle, the main focus of this research is to evaluate the engagement of students in the teaching-learning process in front of these methodologies compared to that of the head teacher of the class
