211	Física das radiações: uma proposta para o Ensino Médio / Radiations physics: a proposal for the High School Wellington Batista de Sousa 14 August 2009 (has links) A sociedade vem questionando os conteúdos presentes no currículo de ciências, quanto ao \"por que\" e \"para que\" ensiná-los. Isso ocorre também dentro do ambiente escolar. Atualmente, o ensino de ciências tem acontecido de maneira bastante desconexa da realidade de nossos alunos, afinal, este ensino não tem apresentado inovações ou trazido temas atualizados para as discussões que ocorrem no ambiente da sala de aula. Apresentamos neste trabalho uma proposta de atualização curricular do ensino de ciências através da inserção de tópicos de Física Moderna e Contemporânea, com base na proposta curricular inserida nos PCNEM e PCNEM+ para a disciplina de Física. Nossa proposta consiste em uma seqüência didática de um curso de Física das Radiações voltado ao Ensino Médio, onde se utilizam as noções de \"marcadores\" e \"marcadores-estruturantes\", desenvolvidas no contexto da teoria da Transposição Didática, para delinear as atividades que acreditamos serem essenciais para que esta nova seqüência de ensino seja exeqüível. / The society has questioned what should be taught in science learning, including both \"why\" and \"what for\" some subjects should be taught. This kind of discussion occurs also inside the educational environment. Presently the science teaching is not connected to the reality of the student, because teaching has not related to scientific innovations, no updated themes are discussed in the classroom. In this work the curricular updating is inserted through the inclusion of Modern and Contemporary Physics topics, as suggested in the PCNEM and PCNEM+. This proposal consists of a didactic sequence of a course on Radiations Physics appropriated to the high school teaching. The concept of \"markers\" and \"structurating-markers\" is discussed within the Didactic Transposition Theory. \"Markers\" are established through the proposed activities, which are supposed to be the essential ones to the learning sequence.
