Biologia molecular: análise de conteúdos em livros didáticos de ciências da natureza do ensino médio

Abstract

This study analyzed the approach to Molecular Biology content in Natural Sciences textbooks for the 1st to 3rd years of High School, focusing on the Multiversos collection by Editora FTD, approved by the PNLD 2021. Given the growing relevance of Molecular Biology in the scientific field, it is essential to evaluate whether the teaching of this content in basic education is carried out effectively and aligned with the guidelines of the Common National Curricular Base (BNCC). The objective was to verify whether the textbooks met criteria such as interdisciplinarity, adequate graphic representations, scientific updates, contextualization, and historicity. The methodology consisted of content analysis based on Bardin's principles, applied to the six books in the collection. The results indicated efforts to integrate content in an interdisciplinary manner but revealed inconsistencies in the uniformity of graphic representations and scientific updates. Furthermore, the contextualization and historicity of the concepts were addressed in a limited way. It is concluded that, although the analyzed materials provided a solid initial foundation, there is room for significant improvements, essential for delivering a more critical scientific education aligned with the contemporary needs of High School.
