Programa de Pós-Graduação em Educação em Ciências e Matemáticas.https://repositorio.ufpa.br/handle/2011/3123This is about an investigation of a study procedure between similar images made by a research community, in a high school class from the public state branch in the outskirts of the city of Belém, seeking to answer if the activities developed by students in classroom characterize a mathematical activity in view of the didactic transposition theory by Yves Chevallard. This is accomplished through collaborative activities that try to identify the flow of mathematical knowledge evoked by students while building a concept of similarity. The research is of a qualitative nature with an ethnographic approach, adapted to education according to Lüdke and André. Analysis show that accomplished activities promote a mathematical action, therefore mathematical activity through the knowledge raised and the links established upon construction of comprehensive models of the concept of similarity by students. Difficulties are outlined as important elements identifying knowledge and their links, such as the research community collaboration eases the studying process.porAcesso AbertoGeometria euclidianaMatemáticaEnsino médioTransposição didáticaCurrículoBelém - PAPará - EstadoAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS HUMANAS::EDUCACAOCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA
