Concepções sobre a natureza e ensino de ciências: um estudo das interações discursivas em um núcleo de pesquisa em ensino de ciências. Revista Brasileira de Pesquisa em Educação em Ciências, Belo Horizonte, v. 9, n. 1, p. 1-23, jan./abr. 2009.e- 1984-2686http://repositorio.bc.ufg.br/handle/ri/14859The conceptions of teachers about the nature of science can significantly influence the form of teaching and decide questions in classroom. From this perspective, this work seeks to relate the experience of the Chemistry Institute/UFG’s centre of research in Science Teaching (NUPEC) in initial and continuing formation of the science’s teacher. We studied discursive interactions in a discussion about the nature of science. These meetings were recorded in audio and video, transcribed and analyzed following a bakhtinian perspective. The results show assimilation of some aspects of scientific thought and of the relation between science and education. In addition, they reveal social structures (patterns of interaction) that evolve a non linear form and can have macro and microdimensional implications.porAcesso AbertoInvestigação didáticaFormação inicialFormação continuadaContinuadaAnálise de discursoDidactic investigationInitial teacher educationOngoing teacher educationDiscourse analysisArtigo
