O USO DO GEOGEBRA NO ENSINO DE TRIGONOMETRIA: UMA EXPERIÊNCIA COM ALUNOS DO ENSINO MÉDIO

Abstract

http://dx.doi.org/10.5902/2179460X14503This research analyzes if the work with GeoGebra facilitates learning concepts of trigonometry and knowing the perceptions of students about the use of GeoGebra in teaching trigonometry. For this, it makes use of application of assessments and interviews with the students of courses of IFRN. Data analysis shows that, with the use of GeoGebra, students showed more significant learning of several aspects of the behavior of the sine and cosine functions when compared with teaching through lectures with the use of teaching resources more common as book and whiteboard. The students themselves recognized that the use of this software is able to help you better understand the aspects of the behavior of these functions, highlighting the ease of use of GeoGebra and the importance of its use in teaching mathematics. However, for the current and future teachers feel able to work with GeoGebra or any other software, it is essential that the vocational training courses for teachers to develop strategies that ensure effectively the ability to use these tools, the critically and creatively way, and not just another fad that will in no way help improve the teacher’s work and the student’s learning.
