Resumo
This dissertation aims to present a teaching proposal that makes it possible to explore and better understand important aspects of the teaching of Trigonometric Functions, using the educational software GeoGebra. The main question is: What potential does this educational technological tool have to contribute to teaching and learning the concepts of Trigonometric Functions? This issue is relevant since several external assessments (Basic Education Assessment System (SAEB), Diagnostic Learning Assessment (ADA), Goiás Education Assessment System (SAEGO)) carried out in High School in the state of Goiás point out that there is, at national and local level, a gap in the teaching and learning of Mathematics. Thus, it is believed that the use of digital technologies can contribute to making Mathematics teaching more attractive to students. This is a research with a qualitative approach, exploratory and bibliographic, in which activities were developed, initially to improve and understand the software and, subsequently, didactic sequences aimed at students in the 2nd grade of High School, with tasks at an increasing level. requirements related to the Sine, Cosine and Tangent Trigonometric Functions. In the elaboration, the dialogue with didactic books and alternatives was sought to dynamically explore the potential of the software, in order to promote the understanding of both the steps and the content covered, through the suggested constructions. It is believed that the ideas presented here may serve as support for various works and projects related to the teacher's own practice or even students of exact science courses who still have difficulties with the subject. With the proposal, it is expected to add more formative possibilities for the teaching of Mathematics and, in particular, for teaching and learning with the help of digital technologies, especially GeoGebra.
