Análise dos conteúdos de toxicologia nos livros didáticos aprovados pelo Programa Nacional do Livro e do Material Didático 2021

Abstract

Textbooks play an important role in the school environment because they are resources that teachers use most frequently when preparing lessons. So, it is necessary that these books contain didactic proposals that contribute to the teaching process, in a perspective of training for citizenship, since these aspects are around science, education and society. Therefore, approaching the content of toxicology in textbooks, in a clear and objective way, can facilitate a better application of the studied concepts to the students' reality. It is important to carry out research that aims to point out how the authors of these books approached this theme. Therefore, in this study, we aimed to evaluate the presence of toxicology concepts in textbooks approved for high school under the 2021 National Book and Teaching Material Program (PNLD). each) were analyzed looking for descriptors related to toxicology. Subjects that report applications on the areas of toxicology were preferably tables and discussed. The results of this study show that almost all the analyzed books, except volume 3 (collection 1) describe the topic of toxicology in different areas, showing that it is possible to work broadly in the areas of toxicology. In the teaching of Chemistry, as well as in the teaching of other disciplines, the use of different forms of presentation is important to improve the understanding of concepts that are often abstract and difficult to understand. In this way, the PNLD sought to establish an interdisciplinary proposal in the books. Thus, it can be said that the development of students' knowledge of toxicology is mediated by the textbook and, therefore, aspects such as language and contextualization must be evaluated both in the selection and in the experimental use of this didactic resource.
