Uma Proposta de inserção de Cosmologia na Física do Ensino Médio

Abstract

Understanding physics discipline is a challenge for high school students, some find it difficult, others do not identify and dislike. Thus, it is important to seek strategies to change this thinking of students. Academic works show that this thinking is due to the neglect of contents of Contemporary Modern Physics. Often subjects about the emergence of the universe, for example, are minorities in teachers' discourses. So, the present work aimed to propose the insertion of Cosmology topics in the discipline of physics, in classes of the First year of high school of a state school in the municipality of Várzea Branca do Piauí, to do research, if, in fact, it is a good strategy to further arouse the interest of students in the physical world. The SD was developed in five forty-minute classes being taught the following subjects: Big Bang Model, Events after the Singularity, Formation of Galaxies, Expansion of the Universe, Dark Matter and Dark Energy. During the application of the SD, two investigative questionnaires were applied in the first and last class and two evaluative activities as a way of analyzing the evolution of the students during the classes. The results show that DS contributed to significant student learning and that it is a good strategy to improve physics teaching
