摘要:In view of the current challenges of today, teaching Science beyond a content form becomes a growing need. In this sense, it is essential to involve students in the process of Scientific Literacy. In the context of the classroom, Inquiry-Based Science Education (IBSE) is an approach that promotes this process and favors interactions in the classroom, especially when making students develop epistemic practices of this approach. However, studies still emphasize the need to improve it, especially in relation to these practices. Therefore, this article aims to investigate, in the light of the Bakhtinian perspective, the contributions of IBSE's epistemic practices to the Scientific Literacy of students in the Early Years of Elementary School. For this, video recordings of an Investigative Teaching Sequence (ITS) were made with a 3rd year class of Elementary School. To analyze the data, the classes were transcribed and we selected Teaching Episodes. Furthermore, we used a methodological construction based on Bakhtinian thinking. As a result, we highlight the relationships that can be established between interactions, the epistemic practices of teaching by Investigation and elements of Scientific Literacy, both of which usually occur concurrently. In addition, we emphasize the importance of teacher guidance during the investigation so that students take the lead in classes and actively participate in the construction of knowledge. Therefore, it is important to continue research that deepens these relationships and promotes investigations in the classroom, aiming at improving the quality of science teaching.
