O objetivo do presente estudo foi investigar como os docentes da área de Ciências Naturais concebem o conceito de interdisciplinaridade e de que forma desenvolveriam um trabalho interdisciplinar a partir de um tema comum sugerido: o Efeito Estufa. Através de questionários dissertativos, os professores-alunos participantes de um projeto de formação em serviço (Pró-Ciências), expressaram suas concepções iniciais a respeito do tema. A análise das respostas obtidas levou-nos às seguintes conclusões: os professores entrevistados têm apenas concepções rudimentares de interdisciplinaridade e confundem este conceito com o de multidisciplinaridade. Afirmam que é possível trabalhar o conceito de Efeito Estufa de maneira interdisciplinar, mas não indicam metodologias adequadas para fazê-lo, devido à carência conceitual apontada anteriormente.

Meaningful learning occurs when new knowledge to be aggregated are grounded in other students already possess. In preparing didactic sequences for teaching concepts, one should take into account these concepts and knowledge to produce more effective and lasting learning, and build new concepts that will become subsumes for subsequent learning. This research was developed in a subproject linked to institutional Scholarship Program Initiation to Teaching (PIBID) of a Universidade Estadual Paulista. The proposal is based on the articulation of the Public School and the University, strengthening the initial training of undergraduates, and continued teacher network, improving the quality of education. The proposed work is based on interdisciplinary research and teaching by investigation. Undergraduates in Biology, Physics, Mathematics and Chemistry jointly propose interdisciplinary teaching activities and investigative applied to high school students of Public School partner. To survey the views of these students on the theme Water, they were asked to draw up an essay entitled "The importance of water", with the aim of organizing information for planning a teaching strategy that articulates the disciplines of training of undergraduates. In this paper we present a qualitative analysis of these essays, performed based on content analysis. The analysis allowed to identify existing concepts in students' cognitive structure and classify them into adequate and inadequate compared to scientifically accepted concepts. Several misconceptions were raised indicating the need to produce didactic sequences that in addition to working the concepts presented in the curriculum of disciplines take into consideration the possibility of more meaningful learning. This research produced the elucidation of existing concepts, indicating where deficiencies were larger. One major contribution was the realization that concepts that may be considered by teachers as simple and already acquired by the students often come so misguided in their explanations. From the results obtained, integrated activities have been planned and implemented, and more relevant to the needs of students aiming to recover and enrich the knowledge they possessed, encouraging the use of scientific concepts and their application to daily living situations.

The theory contemporary in the field of early children education, as well the legal discourse and official texts valid in our country point to the need for systematization of proposals pedagogic / curriculum in institutions, built and carried out by subjects that act as factor of assurance care quality. Quest us about what knowledge are required to teachers in developing a proposed curriculum for children education. Defined as an object of study, the knowledge teachers necessary for the development of a proposed curriculum for children education. As goals, assume: investigate teachers knowledge necessary for the development of a proposed curriculum in a Public Institution for children education and contribute to the (new) meaning on the part of teachers, knowledge needed to build a proposed curriculum for children education. Assuming the principles of the paradigm of qualitative research, we have developed a research institution of a children education Network Public Hall of Ceará-Mirim-RN, which serves children of four and five years old (preschool) with the participation of 17 teachers and two supervisory (teachers) that institution - subject of our research. Therefore, we have adopted the principles of action research, according to which the knowledge gained through research should build so shared / dialogue in the relationship between researcher and participants, what is the implementation of an effective action formative. As the search procedures developed observations no-teaching participants in the meetings and activities of the classroom; semi-structured interviews (individual and collective) with teachers and supervisors; analysis of school documents and participant observation in the seminars of studies reflective. The latter is implemented as key moments of speech and thought, and finally to (new) meaning of knowledge, the subject of the research-action. For these knowledge, the systematization of the register built was developed based on the principles of analysis of Content that guided us to the definition of two categories 1) knowledge teachers concerning conceptions of curriculum / proposed curriculum and 2) knowledge teachers concerning specifics of children education. From these were built subs representing thematings more specific and significant, among the many that emerged in the analysis: 1.1) Definitions of curriculum and curriculum proposal; 1.2) The subjects makers / implementing a curriculum / proposed curriculum; 1.3) elements constituting a curriculum / proposed curriculum for children education and 2.1) Functions of children education and conception of child; 2.2) The space of the play in the organization of routine. Under the intervention could significant advances with regard to (new) meaning of such knowledge from the subjects, with major disruptions to their original designs. These are presented and reflected in this work. In front of this movement, transformation, made the need for a permanent work in the context of the institution of in-service training, or mediated by pedagogical coordinator or other to assume this role with teachers, in order to provide the development and effectiveness of proposed curriculum consistent and contextualized in practice effective with the children concrete envisage the service to their specificities and a quality education

This piece of work has investigated the alternative conceptions shown by students of secondary school, concerned to the concepts of warmth and temperature, aiming the elaboration and application of a learning strategy as of the diagnose risen from the conceptions present in students. The learning strategy was built up by a sequence of activities that involve History of Science and experiments, put in a course that had as a base the proposal of the Group of Redevelopment of Physics Teaching (GREF). We have used as the conductor wire of our research the development of thermo dynamics since the development of the first thermo machines, passing by the Industrial Revolution and the evolution of concepts of warmth and temperature. The learning strategy was applied to a group of second grade of secondary school in a public school in Mossoró (RN). By doing these activities we tried to become the concepts, which are part of thermo dynamics, more meaningful to the students. We have estimated that the application of the strategy has represented some profits to the students of the group, concerning to learning of laws and concepts of thermo dynamics (specifically the concepts of warmth and temperature), as well as what it is referred to the overcoming of its initial conceptions

We report here some outcomes of a research related to a didactical experience aiming to integrate the History of Science to the Physics Teaching, taking as background the historical development of the gravitational attraction. The research, of qualitative approach, is a case study and it was carried out in a sample of eleven students belonging to an undergraduate physics program (called licenciatura in Brazil) designed to from High School physics teachers in a São Paulo State Public University. We tried initially to reveal prospective teachers’ conceptions in order to provide a prepare that was used to guide the activities from the reality’s diagnosis. The aim was to promote discussions on the existence and persistence of alternative conceptions, on the historical evolution of the subject gravitational attraction, through readings and debates of texts contemplating recent subjects on the Science Education research, in order to generate dissatisfaction with traditional teaching models. The future High School physics teachers were asked to construct their own teaching proposal, through the development, in real situations, in a High School, of a minicourse based on: debates and synthesis developed in University classroom, the History of the Science and the student’s alternative conceptions. In this paper we will analyze future teachers’ alternative conceptions, the development of the course proposed, and details of the mini-courses taught by the prospective teachers in real situations, among High School students, its coherence and the posture changes observed in them.

Neste artigo, vamos apresentar o desenvolvimento histórico dos conceitos dos potenciais vetor e quântico formulados, respectivamente, por Maxwell e Bohm. Em suas concepções iniciais, eles foram considerados apenas como um artifício matemático. Contudo, enquanto o potencial vetor já apresenta uma grande evidência experimental (efeito Aharonov-Bohm) sobre a sua interpretação física, o potencial quântico ainda aguarda a sua, muito embora esse efeito e alguns resultados teóricos sinalizem a sua existência física. Este artigo já foi publicado na revista MensAgitat vol.1(2),pp.93- 108(2006) da Academia Roraimense e Paraense de Ciências. Está sendo publicado novamente como e-print no IFUSP para que ele tenha uma divulgação mais ampla e mais ágil pela internet.

This article is about a study about the training needs for teachers of elementary school in the field of Geography. It is our objective to grasp their conceptions of training needs and reflect about their formative needs to teach geography. We consider the training as reflective process that involves the movement of changes and improvement beyond of formal learning, considering its numerous dimensions. We reflected about formative needs in light of the readings of Rodrigues Esteves (1993), Silva (2000), Roberts (2006), Vieira (2010). The discussions about conceptions were based on Ferreira (2007). The empirical reference constitutes to a private school in the city of Ceará-Mirim/RN, SECAT Centro de Ensino. The social subjects of our research are five teachers who work in the initial years of elementary school. We resorted a survey (auto) biographical, based on the studies of Passeggi (2011), Delory (2008), Bertaux (2010) e Josso (2010), since it is our intention to turn to the historicity of the subject and the learning, recognizing the links between him and the world and the experiences based on for learning and adult training. As technical and methodological procedure we will use the Training Narratives, whose application allows the understanding of memories and stories of schooling teachers, since are reported events occurred during the development of the individual through seminars Biographical. We observed on the narratives constructed by the teachers the absence assignments of meanings to a reworking of the theoretical formative needs and questions of its organizing principles. However, we notice the teachers were able to develop senses and means to conceive the phenomenon in study, in a descriptive way, through articulated enunciations, including aspects and opportunities linked to their teaching practices and future formative prospects. Regarding School Geography, we based our studies in the reflections of Smith Junior (1994, 2000), Tonini (2003), Vesentini (2004) and Vlach (1991), among others. We verified that the needs evidenced by the teachers to teach geography were constructed from the contexts of their teaching practices present in their school and professional trajectories. Therefore, we noticed the need for formal pedagogical qualification so that we can conceive the phenomenon in study beyond its descriptive character, understanding that it is necessary to point out reflections and questions about the dynamics of production of global capital, which conveys its interests in the contexts that often emerge formative needs of the educational system

Compreendendo que é essencial aos professores à reflexão sobre a própria prática como estratégia de desenvolvimento profissional, este trabalho investigou as concepções de quatro professoras das séries iniciais do Ensino Fundamental da Escola de Aplicação da Universidade Federal do Pará acerca do ensino e da aprendizagem de Ciências Naturais, bem como a importância que atribuem ao estudo da disciplina nesta etapa da escolarização. Trata-se de uma pesquisa de natureza qualitativa. Visou aproximar ao máximo da realidade e, ao mesmo tempo, dar voz aos sujeitos, entendendo as subjetividades como elementos essenciais à reflexão das práticas educativas. A coleta de dados foi realizada por meio de entrevistas semi-estruturadas e questionário de explicitação, complementar às entrevistas, tratando questões relativas à História de Vida, Escolha e Identidade Profissional e Concepções e Práticas no ensino de Ciências Naturais. Na análise dos dados, foram utilizados referenciais teóricos que subsidiassem a interpretação dos dados e atendessem ao aos objetivos da pesquisa. Foram sistematizados estudos e reflexões sobre: a evolução do conhecimento científico; a história do ensino de Ciências no Brasil; as reformas educacionais e o ensino de Ciências e os modelos didáticos e o ensino de Ciências. O estudo sobre modelos didático é uma produção do Grupo de Pesquisa Investigação e Renovação Escolar, da Espanha, que emprega o conceito de modelo didático na análise do ensino e da formação de professores. Da prática das professoras, foram identificados os modelos didáticos presentes em seus processos de formação docentes, bem como os subjacentes às concepções e práticas no ensino de Ciências nas séries iniciais. Os resultados apontam que, no processo de escolarização e formação profissional, as professoras foram submetidas aos modelos de ensino tradicional e técnico e elas questionam a própria formação acadêmica, em relação às competências necessárias para o exercício da profissão, embora avaliem que tal situação pode ser superada pela formação continuada. Com relação aos modelos didáticos presentes nas concepções e práticas das professoras de Ciências, concluiu-se que não existe um modelo predominante. Dos relatos das professoras, percebeu-se um conjunto de idéias e ações que se aproximam ora de um modelo didático ora de outro, evidenciando que não há um perfil único, que caracterize apenas um modelo didático, mas coexistem concepções relacionadas aos quatro modelos, delineando um modelo de ensino eclético. O que sugere uma transição das concepções das professores sobre a educação e sobre ensino de Ciências. Isso pode caracterizar um processo de desenvolvimento profissional, já que as professoras, apesar das dificuldades para o exercício da docência em Ciências, se mostraram acessíveis às mudanças e inovações.

O estudo apresentou como objetivo geral compreender o Ensino de Ciências Naturais em escolas públicas da região metropolitana de Belém, a partir das concepções e das práticas pedagógicas dos docentes em formação pelo PARFOR que atuam nos anos iniciais do Ensino Fundamental. Os objetivos específicos se resumem em analisar as concepções de ciências naturais dos docentes em formação que atuam nos anos iniciais; descrever as práticas pedagógicas que são adotadas pelos docentes ao ensinarem Ciências Naturais e avaliar se há influência dos Parâmetros Curriculares Nacionais de Ciências Naturais na concepção e na prática pedagógica adotadas por estes professores em formação (que são alunos do PARFOR/UFPA). Como objeto de estudo, centrou-se no Ensino de Ciências em escolas públicas da região metropolitana de Belém, a partir da perspectiva dos docentes em formação no curso de Pedagogia da UFPA. Trata-se de uma pesquisa de caráter qualitativo. A técnica de coleta de dados foi feita por meio de análise documental e de campo, cuja amostra composta por 20 professores da rede pública de ensino que atualmente estão em formação pelo PARFOR no Curso de Licenciatura em Pedagogia do Campus de Belém-Pa. Na coleta de dados, utilizou-se documentos oficiais como os PCN de Ciências Naturais, Relatório de Gestão PARFOR/UFPA e o Projeto Político Pedagógico do Curso de Pedagogia/PARFOR. Aplicou-se um questionário com perguntas abertas e fechadas para investigar as variáveis: socioeconômica, formação profissional, mercado de trabalho, concepções de ciências e práticas pedagógicas. Adotou-se a análise de dados de conteúdo. Por fim, nas considerações finais discorreu-se sobre os aspectos centrais e relevantes da pesquisa, apresentando os resultados e análises mais significativos. O lócus da pesquisa ocorreu no Instituto de Ciências da Educação – Faculdade de Educação – Campus Silveira Neto – Belém-Pará- Brasil. Acredita-se que esse estudo subsidiará outras pesquisas sobre o Ensino de Ciências nos anos iniciais, pois nas bases de dados dos eventos e revistas indexadas da área em questão, ainda não existe nenhum trabalho que reporte a esta temática aqui no estado do Pará. Poderá, também, servir como fonte de pesquisa para outros estudos que surgirem na linha de Educação: Currículo, Epistemologia e História.
