Análise das abordagens didáticas usadas no conteúdo modelos atômicos nos livros aprovados no PNLD 2021

Abstract

Textbooks are extremely important for education in Brazil, as they are a basis for understanding and developing citizenship. With this, the research analyzed the diversification of teaching methods and strategies in Chemistry textbooks approved in the PNLD 2021, with an emphasis on content related to atomic models. The research addressed the relevance of contextualization and interdisciplinarity, highlighting how theoretical concepts were connected to everyday situations and other areas, such as Physics and Biology. The investigation also evaluated the proposed practical activities and the quality of the exercises, highlighting the differences between the books in terms of the depth of the content and its practical application. The analysis revealed that books that prioritized greater contextualization and experimental activities offered a more solid and consistent learning base for the content, while those that presented more superficial theoretical approaches proved to be limiting for a deep understanding of the concepts of atomic models.
