Our work aims to discuss the teaching of science in the context of informal education. Thus, we present and analyze the results of an initiative that we have made seeking to interest high school students to study sciences and technology. The Energy shows are activities which are presented in experimental demonstrations of science concepts to middle school students. After the show the students respond to a questionnaire which formed the basis for this study. The results indicate that the achievement of shows have had an impact on students.

In this article, we present results that express the occurrence of narratives researches in the form of theses and dissertations in postgraduate programs in Brazil, from 2000 to 2010 in the Teaching of Science and Mathematics area. We consulted the Student Registration, on the site of the Coordination of Improvement of Higher Education Personnel, through the keywords: narrative research, narrative inquiry and teacher training. Through reading the abstracts, we identified the area of knowledge, the IES and the supervisor. Of the 162 (one hundred, sixty two) academic productions identified, 31 (thirty-one) are in the area of Science and Mathematics teaching. The data obtained point to the existence of groups of studies and research training in the country engaged in narrative research in Mathematics and Science Teaching, in line with teacher training.

Over the past four decades it occurred a great expansion of science education research in Brazil (TEIXEIRA, 2008). Considering the scientific production in the area, descriptive studies, called state of the art are necessary, but little found in Brazilian scientific literature, especially in the field of science education. In this context, this paper identifies and describes the main features and trends of Brazilian research in the field of education in science museums, released in the form of dissertations and thesis, in the period 1970 to 2010. It is a qualitative and quantitative research, which performs a document analysis, in a bibliographical review. We mapped 153 academic researches, mainly in the Rio-São Paulo axis, mostly in the last decade, showing that the area can be characterized as an emerging field in science education.

We present here a qualitative analysis of a sample of papers published in Brazilian science education journals, which expresses researchers discourses related to Astronomy Education. Within this analytical universe, we sought for discursive excerpts about their justifications for the teaching of this subject, which made the basis for the production of a collective discourse, which identity is socially represented by the researchers authors set. Setting up articulations with discourse analysis, the procedures of the collective subject discourse show to be an important methodological tool to answer to the central question of this study: what do the Brazilian researchers assert as justifications for teaching Astronomy? In other words: why teach Astronomy? Outcomes point to the retaking of reflections about the importance of matters like as Astronomy in formal education, catalyzing teachers work innovative articulations.

This study aimed to reflect on the importance of scientific literacy in science education through São Paulo state curriculum analysis in the area of science pointing possibilities for teaching activities that can envision a better quality teaching. It seeks to understand the importance of science education so that students are able to understand and grasp. In this sense the possibility of a marked formative process in scientific literacy goes beyond just reading and writing, she has for you, the expansion of knowledge in science and technology, so there is an understanding and critical questioning of the nature and the world, thus forming critical and aware citizens, given their role in society. For this work was carried out a literature study on this subject the documentary analysis of the proposed curriculum of the state of São Paulo in science and also the presentation of educational experiences that enhance the physical learning with children

The theme of the writing learning in childhood education has conquered space in academic works, which occupy in analyze and understand how this process in contexts of meaning and not more before the mechanics of learning letters. Thus, in this work, it constitutes general objective to investigate whether and how the practice of teaching of oral and written expression in the last year of child education promotes the development of the symbol (sign) in children, so necessary to the learning of writing from inside to outside. The questions that served as the North for the study were the following: the teaching of writing, in the last year of child education, is organized to promote the development of the symbol (sign) in children? Which and how the ratings graphics made by children demarcate the stage of development of their writing? For its implementation, a bibliographic research was performed, using as a theoretical support for the prospect of Psychology socio-historical, especially authors as Vygotsky (1984), Luria (2001), Oliveira (1995) and Mello (2005). In addition to this was performed the empirical research of qualitative approach, according to his purpose. The data were collected by six instruments: systematic observation and direct in the classroom; audio-recording; records in a field diary, annual teaching plan of the school; lesson plan weekly and material produced by children, result of write activities. By means of the analysis of these data, we note that the writing has been worked from outside to inside, as an imposition, practice that opposes the theory of Vygotsky, already that the writing has been tackled in a way mechanical, in contexts not significant, with focused practices to the trace of the letters and copy of words, exclusive to the notion of symbol. This result points to the emergence of changes in education of writing in childhood education, without which becomes inglorious the search for a pedagogy of writing aware and...

O objetivo desse trabalho consiste em investigar as mudanças subjetivas de um estudante durante a realização de uma Oficina de Ciências e articulá-las, por um lado, com os discursos da professora e, por outro, com a dinâmica de funcionamento grupal. Os dados foram coletados numa escola pública do município de Londrina/PR. No total foram realizados quinze encontros, e o instrumento de coleta de dados consistiu na gravação em vídeo. O grupo selecionado para a pesquisa constituiu-se de quatro alunos do II Ciclo (3ª e 4ª séries) do Ensino Fundamental. O referencial teórico utilizado para análise e interpretação dos dados encontra sua base em conceitos psicanalíticos de orientação lacaniana e da dinâmica de grupos. Concluímos considerando alguns aspectos que podem contribuir para a promoção e sustentação da aprendizagem em grupo em situações de ensino, sinalizando para o papel das intervenções do professor no sentido de promover um trabalho colaborativo.

Este artigo tem como objetivo identificar, com base em registros de observações de aulas de ciências no Ensino Fundamental II, em uma escola da rede pública estadual do município de Valinhos, SP, se a prática pedagógica pode criar condições que potencializem ou limitem a exigência conceitual no tratamento do conhecimento. As análises foram feitas por meio da comparação com outros estudos sobre práticas favoráveis à aproximação ao conhecimento científico, desenvolvidos sob a mesma perspectiva teórica a teoria de Basil Bernstein, e, nesse sentido, ficou evidente o quanto a prática pedagógica analisada se distancia do que vem sendo apontado como uma configuração mais adequada, especialmente por não permitir a intervenção dos alunos na determinação dos tempos envolvidos na aprendizagem, e por preservar rigidamente as fronteiras entre os conteúdos científicos, o que acaba criando condições favoráveis à redução do nível de exigência conceitual nas aulas.

Este estudo teve como objetivo caracterizar as concepções e práticas de avaliação de professores portugueses de Ciências Físico-Químicas do ensino básico e conhecer como estes integram a avaliação nas suas aulas no contexto de uma reorganização curricular. Realizaram-se três estudos de caso, em que participaram professores com menos de três anos de serviço. A recolha de dados consistiu na observação naturalista de aulas, entrevistas semiestruturadas e documentos fornecidos pelos participantes. Os resultados evidenciam duas concepções de avaliação das aprendizagens: avaliação da aprendizagem e avaliação para a aprendizagem. Um dos participantes evidencia uma concepção de avaliação da aprendizagem, valorizando uma avaliação de natureza sumativa. Os professores com uma concepção sobre avaliação para a aprendizagem promovem uma avaliação orientada para a melhoria das aprendizagens, valorizando o carácter formativo da avaliação. Relativamente às práticas avaliativas dos três participantes, verificou-se que os critérios de avaliação não são explicitados aos alunos, o feedback é pouco frequente e os alunos têm um papel reduzido no processo de avaliação. Todos os professores demonstram dificuldades na avaliação das competências atitudinais e processuais, sendo que, apenas um dos participantes elabora registos de observação para avaliar estas competências. Os testes constituem o principal instrumento de avaliação nas aulas dos professores participantes neste estudo, o que é coerente com uma concepção de ensino e aprendizagem ainda, marcadamente tradicional.
