Utilização do software geogebra no estudo de ângulos

Abstract

This paper presents a proposal for the teaching of Mathematics teachers start to use new technologies to support the teaching of angles, enabling students, through the GeoGebra software, view, explore and reflect on their properties and concept. From a script prepared by the teacher and using the tools available in the program, students will develop the activities. The activities developed with the technological resources that exist in schools, encourage curiosity, self-confidence, autonomy and creative potential, serving as motivators and facilitators of knowledge construction. As a result, one can say that the use of technology can and should be part of the teacher's teaching tools, if used properly. Finally, it is a survey of the results, comparing notes on the evaluations of the group which carried out activities on angles in the classroom and Computer Lab with one that only worked in the classroom. Also, lesson plans are presented, which may enhance the teaching practice in the study of angles.
