Ensinando ângulos com o software Geogebra

Abstract

The present work, called Teaching angles with the GeoGebra software, aimed to investigate the importance of using GeoGebra in the teaching and learning of mathematics, mainly in Plane Geometry, in the study of angles in elementary school. The purpose of using Geogebra is due to the variety of resources it can offer and assist in teaching-learning of mathematical content. The previous assumptions partly justify the choice of the theme. However, the main reason is the possibility of working an abstract content, in this case, an angle with the GeoGebra software, making its teaching interactive and allowing students to learn more significant. With this perspective, we elaborated the research problem – How the use of GeoGebra can help teachers and students in the development of geometric skills in the teaching of Plane Geometry? In the feasibility of answering the problem, the general objective was established – To investigate the importance of using GeoGebra in teaching and learning from an angle in Basic Education. To guide the investigation, specific objectives were formulated: to point out important aspects of GeoGebra for teaching and learning mathematics; highlight advantages and disadvantages in using Geogebra for teaching and learning Mathematics; apply activities involving the construction of angles in GeoGebra and analyze the application of GeoGebra in the development of activities in the classroom. The methodological path for the study began with bibliographical research, software presentation, application and analysis of the angle building activities developed with neighborhood children and relatives, who are in the 6th grade of elementary school. The experience was new to most participants and the results were significant, as participants found it very interesting to learn using the application.
