Interlocuções entre a alfabetização química do ensino médio e os objetos de conhecimento em livros didáticos das ciências da natureza do PNLD 2021. Orientadora: Dra.

Dissertação (Mestrado em Ensino de Ciências e Matemática) - Centro de Ciências Exatas e da Terra, Universidade Federal do Rio Grande do Norte, Natal, 2025.https://repositorio.ufrn.br/handle/123456789/63887The aim of this research was to investigate how the Natural Sciences textbooks approved in the 2021 National Textbook Plan (PNLD) Guide present the conceptual content and constituent elements that favor the development of Chemical Literacy, considering the reference documents for Basic Education, BNCC and LDB, in the context of the Brazilian High School Reform. To this end, the following research problem was posed: How do the conceptual contents present in textbooks approved by the PNLD 2021, corresponding to the Multiversos Ciências da Natureza collection, which are based on LDB Nº 9.394/1996 and BNCC (Brasil, 2018), influence Chemical Literacy in the state of Rio Grande do Norte? The qualitative study, based on Stake (2011), used Bardin's Content Analysis (2011) as its analytical method, in six volumes of the “Multiversos - Ciências da Natureza” collection. Four main dimensions were adopted for the analysis, based on the literature on Chemical Literacy: i) Aspects of the Nature of Science in Chemistry; ii) Chemistry in Everyday Life; iii) Knowledge of the Nature of Matter; iv) Higher Order Learning Skills (Shwartz et al., 2004, 2005, 2006, 2013). Based on the analysis of the textbooks in the aforementioned collection, 29 chemistry concepts were catalogued, and we found that these dimensions are covered throughout the conceptual content, boxes and complementary sources. Considering our references and the analysis carried out, we conclude that the collection does not provide ample support for the development of Chemical Literacy that stimulates critical analysis and problem solving, which are fundamental for understanding chemical concepts that are intrinsic/present in man's relations with society. In this research, we identified that only two concepts (C8 and C6) of the Chemistry knowledge objects analyzed fully corroborate the process of developing AQ in high school in RN, through the current reform.pt-BRAcesso AbertoAlfabetização químicaLivro didáticoPNLDReforma do ensino médiomasterThesisCIENCIAS EXATAS E DA TERRA::MATEMATICA
