Análise didática da astronomia em livros didáticos do ensino médio, aprovados no PNLD 2021

Abstract

Astronomy is the science that deals with understanding how the Universe works. It was born from the fascination of those who observed the skies, enchanted by the precision of events, even before physical studies. Therefore, it is essential that this topic is present in high school Physics textbooks in an accessible way. Thus, the present work aims to provide an analysis of how this science is approached in the textbooks approved in the 2021 National Textbook Program. In view of this, such approaches must be measured and compared with each other, in order to understand how in-depth this theoretical subject is in teaching works. To this end, this proposal is assumed to be bibliographical research, as it requires a documentary analysis. This work is qualitative in nature and is based on content analysis, we are guided by the three phases proposed by Bardin (2006): pre-analysis, exploration of the material and treatment of results, inference and interpretation. The work used the National Textbook Program and the National Common Curricular Base to shape the perspectives of what demand is made for didactic works. Thus, with the results, we discovered that the books have similarities in basic content of the main topic, but also contain differences between them in subjects that are rarely covered.
