A Atenção Voluntária na Construção de Conceitos Trigonométricos em Ambientes de Geometria Dinâmica

Abstract

This article presents the results of the project, obtained through didactic sequences applications. The objective was to investigate the voluntary attention span of students when subjected to Dynamic Geometry Environment (GDE) in the exploration of trigonometric concepts. To carry out the didactic sequences was used GeoGebra software, a free Dynamic Geometry Environment software that allows the identification of algebraic and geometric concepts simultaneously in an interactive interface and simples. The methodology used, regarding the approach of the problem, was defined as qualitative, regarding the objectives of exploratory form and as for the research technique, case study Para support the research used the Socio-Historical theory of Vygotsky, and to address the semiotic issues was based on the theory of Duval. From the implementation of the project highlighted the importance of using these environments to obtain the voluntary attention of students in the trigonometric concepts construction process.This article presents the results of the project, obtained through didactic sequences applications.
