Análise de textos de divulgação científica sobre questões ambientais em livros didáticos de ciências da natureza e suas tecnologias

Abstract

In this study, we seek to analyze the inclusion of popular science texts on environmental issues in natural science and technology textbooks, adopted in the National Textbook Program (PNLD) of 2021. This work is part of the undergraduate course in chemistry, belonging to the Federal University of the Southern Border (UFFS). In this study, the popular science texts have environmental issues as their central theme. This choice was made due to the growing need to discuss environmental issues in society, the consequences of which are already felt more and more intensely. In the first part of our analysis, we characterize the way in which popular science texts are incorporated into textbooks. In a second moment, we carry out a deeper analysis of some of these texts, highlighting, for example, the emphasis given to the topics addressed from the theme "climate change", as well as the context of their inclusion in the units and chapters of the books. The research problem revolves around how popular science texts on environmental issues circulate in natural science and technology textbooks and what the implications of these texts are for the development of environmental themes, specifically climate change, within the school context. Therefore, during the analysis, we identified several relevant themes, such as deforestation, fires, ocean acidity, species extinction, climate change, the struggle of indigenous peoples for their territories, soil and water pollution, use of pesticides and preservation of Brazilian biomes, among others. Based on the results obtained, we can infer that such texts circulate in different forms in the books, including exercises, tables, illustrations, boxes and other strategies. In addition, these insertions present a variety of sources that can help teachers promote discussions on environmental themes in the classroom.
