Energia no Ensino Médio: Com a palavra os autores dos livros didáticos do PNLD

Abstract

This research analyzed the approach of energy content in books of high school physics. Eight were selected and analyzed physics books referring to the classes of the first year of high school, approved in the National Textbook Program (PNLD) 2018.In order to be able to perform the analysis it was necessary to highlight some important topics that should generally be addressed in the energy content. Therefore, in each book a data collection was made related to such content, such as: exact definition of energy, open definition, kinetic energy, proposed problems etc.Therefore, the didactic analysis was carried out with the aid of theoretical foundations and through comparison with each other. Through these, it was observed that these books have advantages and disadvantages, but in general are suitable for teaching and learning practices, as they are quality materials for and meet the national parameters established for this level of education.It is important to point out that there are among these books works that give more or less emphasis on certain contents within the theme analyzed, books also differ by the way they address problems. However, it is interesting to note that these authors different methodologies to address this extremely important content, because it allows the teacher to choose the book that most identifies himself to assist in your classes.
