Análise do impacto do ensino da trigonometria na educação básica, com ênfase nos alunos do 2º ano do ensino médio de uma escola da cidade de Maceió/AL

Abstract

The present work aims to demonstrate how the teaching of trigonometric relations in the right triangle is built with a dynamic and participatory teaching of the student, under the application of the Van Hiele model in the 2nd grade of High School in a private school in the city of Maceió/AL. The study will survey 11 students about the teaching of trigonometry in the right triangle, presenting the level of understanding that the student brought from Elementary School. Taking into account aspects of the knowledge that the student already has and how this knowledge will be useful in the construction of the teaching-learning process of the content in question. For this, aspects of the Theory of Meaningful Learning and the Theory of Conceptual Fields of Vergnaud were presented, in addition to raising the importance of using software such as Geogebra and ICTs during teaching. It is also worth mentioning the roles that must be played by the teacher and student, the teacher assuming his place and mediation between knowledge to be built and knowledge already absorbed by the student, and the student as an active part in his teaching-learning process. It is concluded that the teacher has the potential to change the way of teaching, ensuring better student learning, the right stimuli develops the student and leads to his maximum potential.
