The discursive production in science classes through the science communication: The case of the use of direct speech

Abstract

This paper presents an investigation about the role of science communication in the discursive production of scientific and technological culture in the classroom. It aims to understand the use of direct speech by the science teacher in formal teaching situations. The work analyses a case in which a science teacher of 9th grade elementary school uses a book of science communication, Billions and Billions written by Carl Sagan, to explain and contextualize scientific notation in a didactic sequence about the micro and macrocosm. The theoretical-methodological framework was based on the contributions of Bakhtin and the circle. The analyzes were based on a qualitative approach, which can be classified as a case study, selected from a set of didactic sequences produced in a specialization course in Science Teaching. The results indicate a hybrid enunciative production that brought together distinct ideological spheres of creation (science communication and science education) to contemplate a specific purpose that was determined by the teacher, in addition to a diversified intertwining between the scientific dissemination discourse and the school scientific discourse.
