The context of the current science teaching is also presented. Besides, the following aspects are discussed: the preparation of the eighth grade teachers, their professional needs, the pedagogical practices and the theoreticmethodological difficulties faced by them. Another important issue in Science Teaching, which is also discussed in this dissertation, is the need for an efficient scientific literacy so that the citizen may express value judgment about Science and Technology issues. The data about the context were gathered from questionaires answered by the teachers. In value of this information, lesson plans were elaborated and implemented. The goal was to point out alternatives for the development of a teaching-learning evaluation which would be both pleasant for the teachers in relation to the implemented methodology, end meaningful for the students by adding elements such as: interdisciplinary approach, contextualization and preparation by competences. Furthermore it was carried out a deeper analysis of the Brazilian curriculum references (LDB, DCN, PCN, RCB) and content aspects (concepts, procedures e attitudes) to be executed by that branch of human knowledge, aiming at a really Contextualized Science Teaching, qualified and pleasant for the eighth grade level. It is also presented in this paper the profile or the Professional which teach this level at state public schools in Russas, state of Cear?, Vale do Jaguaribe Region. The efficacy of the lesson plans were also analysed by using evaluation procedures with the eighth grade students of the following schools: CAIC Senador Carlos Jereissati and EEF Manuel Matoso Filho, from which the concepts acquired during the implementation of the classes became evident in the students / O presente trabalho versa sobre a investiga??o e poss?vel interven??o, no contexto atual do ensino de f?sica, em especial o de ?ptica, na oitava s?rie/nono ano/IV Ciclo do Ensino fundamental. Mostramos o contexto do Ensino de Ci?ncias atual bem como, discutimos a forma??o, necessidades profissionais, as pr?ticas pedag?gicas e dificuldades te?rico-metodol?gicas enfrentadas pelos professores desse n?vel. Outra quest?o importante no cen?rio do ensino de ci?ncias, e que discorremos aqui ? a necessidade de Alfabetiza??o Cient?fica efetiva para que o cidad?o possa emitir ju?zo de valor a respeito das quest?es relativas ? ci?ncia e ? tecnologia. Essa disserta??o pretendeu, ainda, partindo do contexto identificado nos question?rios aplicados aos professores, apontar, atrav?s da elabora??o e implementa??o de planos de aula, alternativas para o desenvolvimento de um ensino-aprendizagemavalia??o prazeroso, quanto ?s metodologias implementadas, bem como significativo para o educando, atrav?s da incorpora??o de elementos como: Interdisciplinaridade, contextualiza??o e forma??o por compet?ncias. Aprofundamos, ainda, a an?lise dos referenciais curriculares (LDB, DCN, PCN, RCB) e dos tipos de conte?dos (conceituais, procedimentais e atitudinais) a serem trabalhados por esse ramo do conhecimento humano, visando assim, um ensino das ci?ncias realmente contextualizado, de qualidade e agrad?vel nesse n?vel de ensino. Apresentamos o perfil do Profissional que atua, neste n?vel de ensino, na rede p?blica estadual de ensino da cidade de Russas CE, regi?o do Vale do Jaguaribe. Analisamos tamb?m a efic?cia dos planos de aula atrav?s de procedimentos avaliativos aplicados aos alunos da oitava s?rie das Escolas: CAIC Senador Carlos Jereissati e EEF Manuel Matoso Filho, a partir dos quais evidenciamos os conceitos adquiridos durante a implementa??o das aula
