In this study, we present some reflections on a work in classrooms of eigth grade, done by a class of Biological Sciences, specifically in the disciplines of Methodology and Instrumentation for the Science Teaching. The main goal is to create opportunities for future teachers to experience daily life in a public school, developing an intervention in a didactic discursive perspective in STS education. Thus, our references have been based on analysis of speech and functioning of language in science and technology classes. We presented and discussed some results over the initial education of science teachers and the relevance of thematic approach for the construction of social-cultural and environmental meanings of the contextualized scientific knowledge.
