In order to answer this question, we define the general objective: to analyze how the study of Astronomy, as a mediating element for the introduction of Modern Physics in High School, can favor the teaching and learning of Physics, from the perspective of SAT, in the 3? Series. In order to achieve this purpose, we have drawn up the following specific objectives: to elaborate and evaluate the contribution of a didactic sequence on Electromagnetic Radiation, developed from the perspective of SAT, in the teaching and learning of Physics, in the 3? High School Series; To introduce the study of Modern Physics mediated by Astronomy, with support of didactic sequence on Electromagnetic Radiation, from the perspective of SAT; To evaluate students' performance from the introduction of Modern Physics, mediated by the study of Astronomy, with the support of the Didactic Sequence from the perspective of SAT. From this perspective, it was developed in a senior high school class, in a public school from Santo Antonio de Jesus town, State of Bahia, and entitled "Knowing the Universe Through the Colors". The same had as its central theme Electromagnetic Radiations and constituted both an instrument and product of this research. The activities were designed in a way that would attract students' attention from the curiosity that usually astronomical phenomena cause in those who observe them. At the time they were arranged in ascending order in terms of complexity, and the correlation between them. This research has been prepared under qualitative and quantitative approach, from which have developed a descriptive understanding work of the investigated object. Finally, this study shows a very positive result of the methodology chosen and can say that the Didactic Sequence elaborate contributed to a meaningful learning of concepts covered in Modern Physics, mediated by Astronomy, enabling students to build knowledge that can serve as anchors for future concepts. / Este trabalho consistiu em investigar como a introdu??o da F?sica Moderna no Ensino M?dio, mediado pelo estudo da Astronomia, pode favorecer as pr?ticas de ensino e aprendizagem da F?sica, na perspectiva da Teoria da Aprendizagem Significativa (TAS), a partir do uso de Sequ?ncia Did?tica. Buscando resposta para este questionamento definimos o objetivo geral: analisar como o estudo da Astronomia, enquanto elemento mediador para a introdu??o da F?sica Moderna no Ensino M?dio pode favorecer a pr?tica de ensino e aprendizagem da F?sica, na perspectiva da TAS, na 3? S?rie. Para alcan?ar esse prop?sito tra?amos os seguintes objetivos espec?ficos: elaborar e avaliar a contribui??o de uma sequ?ncia did?tica sobre as Radia??es Eletromagn?ticas, desenvolvida na perspectiva da TAS, no ensino e aprendizado da F?sica, na 3? S?rie do Ensino M?dio; introduzir o estudo da F?sica Moderna mediado pela Astronomia, com suporte de sequ?ncia did?tica sobre Radia??es Eletromagn?ticas, na perspectiva da TAS; avaliar o desempenho dos estudantes a partir da introdu??o da F?sica Moderna, mediado pelo estudo da Astronomia, com o suporte da Sequ?ncia Did?tica na perspectiva da TAS. Nessa perspectiva, foi desenvolvida em uma turma da 3? S?rie do Ensino M?dio, de um Col?gio Estadual do munic?pio de Santo Ant?nio de Jesus, no estado da Bahia, a Sequ?ncia Did?tica intitulada ?Conhecendo o Universo Atrav?s das Cores?, a qual teve como tem?tica central Radia??es Eletromagn?ticas. Esta constituiu-se, simultaneamente, em instrumento e produto da presente pesquisa. As atividades foram pensadas de maneira que atra?ssem aten??o dos alunos, a partir da curiosidade que geralmente os fen?menos astron?micos causam naqueles que os observam. Ao tempo em que foram organizadas de forma ascendente, em termos de complexidade, e primando pela correla??o entre elas. A presente pesquisa foi elaborada sob abordagem quali-quantitativa, a partir da qual desenvolvemos um trabalho descritivo-compreensivo do objeto investigado. As Considera??es Finais evidenciam um resultado muito positivo da metodologia escolhida, podendo dizer que a Sequ?ncia Did?tica elaborada contribuiu para uma aprendizagem significativa dos conceitos abordados da F?sica Moderna, mediados pela Astronomia, possibilitando aos alunos, a constru??o de conhecimentos que poder?o servir de ?ncoras para conceitos futuros.
