Análise da abordagem de fontes de energia nos livros didáticos de química do ensino médio

Abstract

The textbook is a resource commonly used in the classroom and it is a type of material consisting of contents, proposals and intentions. This study is a qualitative and descriptive research that aimed to analyze, in a document review, the presence of energy sources and their environmental impacts in the Chemistry textbook of High School. For this purpose, 9 books were chosen and the material was analyzed considering the way the energies appear in these books, the associated chemistry content, the type of experimentation and if these energies are renewable or not. Based on the analysis, it is concluded that most of the books present the content in special sections, instead of the main text of chapter and not always the appearances explore basic concepts of chemistry, as chemical reactions involved or the chemical processes impact on nature. Some suggested activities have Interdisciplinarity Among Teachers and instigate problems for student investigation. Furthermore, the apparition of non-renewable energies was higher than the renewable energies. Therefore, it is concluded that the carefully chosen textbook may promote critical Environmental Education, presenting energy sources as a training resource and contributing to comprehension of basic concepts and expanding the preparations of alumns for a conscious action in society.
