Acesso em: 10 set. 2025.e- 1982-2413https://repositorio.bc.ufg.br//handle/ri/28754This study aimed to present and reflect upon an experience of incorporating the themes encompassed by Law 10.639/03—which mandates the teaching of African and Afro-Brazilian history and culture in basic education—into a teacher training program for Chemistry educators at a state university in the Central-West region of Brazil. More specifically, the focus was on the extraction of blue dye from Indigofera tinctoria, considered as a form of biotechnology originating from western Sudan (Mali). A pedagogical intervention (PI) was developed within a specific mandatory course in the program, targeting students in their seventh semester. The intervention was audio-recorded and subsequently transcribed for later analysis. The investigation was characterized as an action research project, and the data were examined through Conversation Analysis (CA). Our results revealed contradictions in the development of the PI related to discussions on racism; we identified epistemic shifts within the proposal, and we found it possible to discuss chemical concepts alongside topics related to African heritage and African history.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/3.0/us/Lei 10.639/03Formação inicial de docentesCultura africanaCorante azulLaw 10.639/2003Initial training of teachersAfrican cultureBlue dyeArtigo
