摘要：O artigo apresenta os resultados de pesquisa do projeto sobre a utilização de ambientes de Geometria Dinâmica (GDE), obtidos por meio de aplicações de sequências didáticas. O objetivo foi investigar o tempo de atenção voluntária dos estudantes quando submetidos aos ambientes de GDE na exploração de conceitos trigonométricos. Para a realização das sequências didáticas foi utilizado o software GeoGebra, um software de Ambiente de Geometria Dinâmica livre que permite a identificação de conceitos algébricos e geométricos simultaneamente em uma interface interativa e simples. A metodologia utilizada, quanto à abordagem do problema, definiu-se como qualitativa, quanto aos objetivos de forma exploratória e quanto à técnica de pesquisa, estudo de caso. Para dar suporte utilizou-se a teoria Sócio-Histórica de Vygotsky, e para tratar das questões semióticas fundamentou-se na teoria de Duval. A partir da aplicação do projeto destacou-se a importância da utilização destes ambientes para a obtenção da atenção voluntária dos estudantes no processo de construção de conceitos trigonométricos.
其他摘要：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.
