O problema da matéria escura: astrofísica contemporânea no ensino de física

Abstract

This work presents a research study that investigates how a didactic sequence focused on the presentation and discussion of dark matter in teaching-learning processes in high school physics classes can influence the understanding of some basic physics concepts. To theoretically support this dissertation, the ideas of Gaston Bachelard were used, especially the concepts of epistemological profile and epistemological obstacles. The didactic sequence was applied in a third-year high school class at a public school in Flores da Cunha, Rio Grande do Sul. The analysis of the results led to the development of an improved version of the didactic sequence, resulting in the educational product of this dissertation. The results indicate a significant positive potential for the implementation of the theme of dark matter in discussions at the high school level. [resumo fornecido pelo autor]
