Construção e aplicação de uma sequência didática para o ensino de trigonometria usando software geogebra. 2010. 141 f. Dissertação (Mestrado em Ensino de Ciências Naturais e Matemática) - Universidade Federal do Rio Grande do Norte, Natal, 2010.https://repositorio.ufrn.br/jspui/handle/123456789/16068The present study aims to analyze the potentialities and limitations of GeoGebra software on what concerns trigonometry s teaching and learning processes. Taking the present resources of public school from the state of Rio Grande do Norte, the research intends to answer the following question: Could we use the current conditions of public school and the Geogebra software to optimize the trigonometry s learning and teaching processes situation? . To make it a possible to answer the question above, a module of investigative activities was created and applied. The methodological intervention was made among second year High School students from a public school in Natal, RN. The theoretical reference of Mathematics Didactics was taken was a base, adopting the conceptions of Borba and Penteado (2001), Valente (1999) and Zulatto (2002, 2007) about the use of Information Technology (IT) on Mathematics classrooms. In order to create the investigative activities helped us to understand how the students make their constructions and their visual perception through the process of dragging images on the computer screen. Furthermore, the activities done with the GeoGebra software s resources facilitate the resolution of trigonometry situationsapplication/pdfAcesso AbertoEnsino e aprendizagem de trigonometriaAtividades investigativasSoftware geoGebraTrigonometry learning and teaching processesInvestigative activitiesGeoGebra softwaremasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA
