Abordagens do conteúdo movimentação dos corpos em livros didáticos no 1° ano do ensino médio

Abstract

The movement of bodies is a fundamental topic for understanding various phenomena studied in Physics, being essential, mainly for understanding the basic principles of Kinematics and Dynamics in the description of the principles that govern the movement of objects in space. This work aims to analyze the approaches to the topic of body movement in textbooks used in the first year of high school, making a comparison between the 2018 National Textbook Plan, prior to the high school reform, and the same 2021 plan, post highschool reform. The bibliographical research was carried out through the analysis of textbooks suggested in the National Textbook Plan 2018 and 2021 widely used in schools in the periods before and after the secondary education reform. Considering different publishers, the sections and chapters related to the movement of bodies were examined, taking into account the organization of the content, the examples and exercises proposed, in addition to the theoretical and practical approaches, as well as their interdisciplinary relationships and with everyday situations. The analysis of the approaches present in textbooks was necessary to identify the way in which this content is presented to students in the first year of high school. To make it possible to verify the changes in the textbooks resulting from the reduction in the workload of Physics subject, caused by the reform of secondary education, the negative consequences generated by such changes were also observed, noting that the books, post reform, analyzed they appear to be superficial in their approaches to the content of body movement.
