GeoGebra e o estudo das funções trigonométricas no Ensino Médio

Abstract

We present a research which investigates the GeoGebra software capabilities as technological instrument conducive to learning of the trigonometric functions in high school, from the graphical representations of these functions. It is a survey characterized by a qualitative approach in which a didactic sequence of activities was used, with tasks at a level of growing demand. Each of this research execution phase is supported by the theoretical assumptions of the Didactic Engineering methodology used in research involving an experimental part. The arguments arising from the analysis are based on the Anthropological Theory of Didactic. For the development of digital educational resources for teaching trigonometry, which will apply to a group of high school students, used the GeoGebra software. Related to research, educational product offered here brings together the applied tasks and with guidance for using it in the classroom.
