Análise das contribuições de um estudo de caso abordando controvérsias históricas para as discussões sobre natureza da ciência na formação inicial de professores de química

Abstract

Many researches in the field of chemistry teaching point out the importance of including the history of science in scientific disciplines. Certainly, the teaching of the history of science not only helps in understanding about science and its development, but also the way students will express themselves, exposing their opinions. Thus, this paper aims to analyze the contributions of a case study containing historical controversies on the theory of valence for discussions about the nature of science. For that, a case study containing a historical controversy on the development of valence theory was applied in a History of Chemistry class of the UFRPE / UAST Chemistry undergraduate course. In addition to the case study, which was filmed, in order to analyze the discussions carried out by the licensees, an initial and final questionnaire was also applied in order to verify the students' knowledge. The results indicate that the case study favored some discussions about the nature of science to emerge during case discussions, which indicates the historical case study as a good strategy for discussions about science.
