Textos de divulgação científica em livros didáticos de ciências: uma análise à luz da teoria da transposição didática

Abstract

The science textbook has been representing, over the years, an instrument of strong representation in the school environment, with the promotion of scientific education from elementary school. Because of this representativeness, research has been carried out in the last decades, resulting in several criticisms about the quality of the textbook. Faced with the social and cultural reality in which each student lives, aiming to bring scientific knowledge to the lay public, changes were proposed in the textbook, one of them being the incorporation of TDC (text of scientific dissemination), with the aim of bringing the Students to the process of learning science. The present work presents an analysis about the relationship between the TDC and its correspondence with didactic texts present in science textbooks. The data collection was based on the websites of the Ministry of Education - MEC, the National Institute of Studies and Research in Education - INEP and the Guide to the Science Didactic Book - final series - 2014, regarding the distribution of textbooks in Municipality of Foz do Iguaçu / PR. This research identified the texts of scientific dissemination of two science textbooks for the 7th year of elementary school, among the textbooks most adopted by the teachers of the municipality. In the possession of the book distribution numbers by city, it was possible to verify that the collections most adopted by teachers in public schools in the city of Foz do Iguaçu / Paraná / Brazil were: "Natural Sciences - Learning with everyday life" and "Teláris Project". In order to analyze the texts of scientific dissemination present in the textbook of science, we use as theoretical reference the categories of didactic transposition proposed by Yves Chevallard (2008). As a result of the interaction analysis of the didactic text with the texts of scientific dissemination, from the perspective of didactic transposition, adaptations and modifications were identified in some texts of scientific dissemination incorporated in the didactic book of sciences, contributing in the contextualization of scientific knowledge for the lay public and creating opportunities to make the textbook more attractive to the reader. Therefore, it is important to understand the process of didactic transposition by the authors of textbooks and a greater rigor in the processes of incorporation of these texts, since the TDCs are important didactic resources in the didactic relation between teacher, student and knowledge.
