A utilização do software geogebra como ferramenta para o ensino de funções

Abstract

This study aims to investigate the use of software GeoGebra for teaching functions. Currently there is great interest in the use of new technologies in the class room as an additional resource for teaching mathematical content, as these are considered a valuable resource fixation of ideas and knowledge in this area of knowledge. GeoGebra is a software Mathematics, free and dynamic, which can be used in a classroom setting or online, and combines elements of Geometry, Algebra and Calculus. The content of functions was chosen to be a relevant topic to the basic education curriculum and that students have demonstrated great difficulty in solving problems involving graphs, specifically regarding the interpretation and identification of properties. To do so will make the presentation of the software, its history, the structure of GeoGebra and possible applications of their tools give you some instructions and examples. Then we will make a brief history of the key concepts presented, aiming to highlight the importance of the issue and the different ways of approach. At the end of the study, we present suggestions for activities and teaching sequences that can be used in the preparation of lessons on the subject discussed. Our aim is to suggest that the classes for the cited content have a different approach.
