The teaching of trigonometry using the Geogebra software as a teaching - Learning tool

Abstract

Researches have been revealing the great technological advancement and its potential in all fields and how its use can cause good results in the educational area. It is noted that technology is a great ally of all people and one of the points highlighted in this work is the use of technological means to use them as tools in the teaching-learning process. Therefore, this research was developed as an alternative for the teaching of Trigonometric Functions, specifically Sine and Cosine, using a  free software to improve the graphic visualization of the functions, the understanding and the interest of students in the subject. This computational resource provides students and teachers with another environment in which learning can be stimulated, through the union of computer resources directed to the teaching of mathematics. Thus, this work aims to analyze how much Geogebra can contribute to the teaching of trigonometric functions, exploring their variations in relation to the resources that the software has. The work was developed in two classes of the second year of high school at the Federal Institute of Northern Minas Gerais, Salinas Campus. In the research, activities were developed on the variations of the sine and cosine functions. One class developed the activities using only basic school materials for mathematical study and in the other, the Geogebra software was used  as a tool, in order to improve visualization and understand variations. The results of the activities revealed that the Geogebra software  presents itself as an important educational tool in the visualization, understanding of the elements, concepts and their variations. Therefore, this teaching methodology presented us with the benefits of the technique in favor of mathematics education, using a  specific software to contribute to the student teaching-learning process.
