Pesquisa do Estado da Bahia - FAPEB / In this dissertation we present as proposal the teaching of Star Evolution in the discipline sciences for students of the 9th year of elementary school. From this series, students have their first contact with study of the atomic structure, periodic table, chemical reactions, among other topics of physics and chemistry. Using Stellar Evolution, in an interdisciplinary way, we were able to discuss these obligatory contents and, in addition, we present new knowledge such as: the synthesis of chemical elements, nuclear reactions and other topics of Astronomy and Astrophysics. This approach allows students to gain access to modern physics content guided by NCPs, which in turn has been neglected in school curricula. Based on Chevallard's Didactic Transposition Theory, we analyze the aspects that make it possible to adapt the Wise Knowledge, Star Evolution, to the reality of basic education. To do so, we did initially a quantitative survey in textbooks, evaluating how the knowledge related to Astronomy has been presented. The second step was to perform a pre-test to evaluate students' prior knowledge, and then compare them with a post-test. The transposition of these contents indicated that the Star Evolution in conjunction with the science discipline makes learning more playful and meaningful, being a perfectly feasible proposal, as well as showing the results. In addition, we constructed a didactic game, an educational product that can be used as a tool that helps students learn the evolutionary processes of the stars. / Nesta disserta??o apresentamos como proposta o ensino de Evolu??o Estelar na disciplina ci?ncias para alunos do 9? ano do ensino fundamental. A partir desta s?rie, os alunos tem seu primeiro contato com estudo da estrutura at?mica, tabela peri?dica, rea??es qu?micas, entre outros t?picos de f?sica e qu?mica. Usando a Evolu??o Estelar, de um modo interdisciplinar, pudemos discutir estes conte?dos obrigat?rios e, al?m disso, apresentamos novos conhecimentos como: a s?ntese dos elementos qu?micos, rea??es nucleares e outros temas de Astronomia e Astrof?sica. Esta abordagem permite que os alunos tenham acesso a conte?dos de f?sica moderna orientados pelos PCN, que por sua vez, tem sido ainda negligenciado nos curr?culos escolares. Com base na Teoria da Transposi??o Did?tica de Chevallard, analisamos os aspectos que tornam poss?vel adequar o Saber S?bio e a Evolu??o Estelar, ? realidade do ensino b?sico. Para tanto, fizemos inicialmente um levantamento quantitativo em livros did?ticos, avaliando como os Saberes ligados a Astronomia tem sido apresentados. O segundo passo foi a realiza??o de um pr?-teste para avaliarmos o conhecimento pr?vio dos estudantes, e posteriormente compar?-los com um p?s-teste. A transposi??o destes conte?dos indicou que a Evolu??o Estelar em conjunto com a disciplina ci?ncias torna o aprendizado mais l?dico e significativo, sendo uma proposta perfeitamente vi?vel, assim como mostram os resultados. Ademais, constru?mos um jogo did?tico, produto educacional que pode ser usado como ferramenta que auxilie os estudantes no aprendizado dos processos evolutivos das estrelas.
