A tecnologia do motor elétrico para o ensino de eletromagnetismo numa abordagem problematizadora. Revista Brasileira de Ensino de Ciência e Tecnologia, Ponta Grossa, v. 6, n. 3, p. 29-45, set./dez. 2013.e- 1982-873Xhttp://repositorio.bc.ufg.br/handle/ri/16900We discuss the development of dialogical and problem-posing lessons by a technological object in order to investigate its contributions to the teaching of Electromagnetism. Therefore we developed the strategy of the three pedagogical moments: initial problem-posing, knowledge organization and knowledge application. The research was conducted with students of the 3rd year of high school from a private school. This is a qualitative research whose results were obtained from the content analysis of a diary and answers to a questionnaire with open questions. We conclude that the technological object with problem-posing approach mobilizes epistemological curiosity, promotes the dialogue establishment, reveals the applied aspect of scientific knowledge and facilitates conceptual understanding.porAcesso AbertoEquipamento geradorEletromagnetismoProblematizaçãoGenerating equipmentElectromagnetismProblem-posingArtigo10.3895/S1982-873X2013000300003
