O objetivo deste estudo é buscar compreender aspectos do trabalho experimental no ensino de Física no Brasil no passado, focalizando um instrumento antigo - o tubo de Newton. Considerando que a partir da Reforma Francisco Campos, em 1931, houve uma expansão do ensino secundário brasileiro e um aumento da presença de disciplinas científicas no currículo desse curso, examinamos as recomendações oficiais para o ensino de Física de 1931até 1961, quando foi promulgada a primeira Lei de Diretrizes e Bases da Educação Nacional. Procuramos investigar como o uso do tubo de Newton aparece em livros didáticos de Física para a educação secundária, editados em nosso país, no período delimitado. Em nossas conclusões consideramos que o conhecimento histórico pode ajudar a compreender aspectos relevantes a respeito do papel da experimentação no ensino de Física em nossos dias.

The integration of research in teaching practices assumes increasing importance and complexity in education. One aspect involved in this issue and poorly investigated is the training of teachers for the development of research linked with their practices. In this context, we present a training for research developed on a distance-learning course in the Science Teaching, which involves the design, implementation and analysis of didactic sequences: the Study Guide to the Initiation of the Term Paper (SGITP). Our research goal is to present a training proposal produced from the results collected from a survey of the literature of the area, and to investigate its application and its results in the teachers' continuing education program. Using data extracted from the production of students and tutors, we concluded that SGITP had a good acceptance among them and it was positively evaluated by teachers, in addition to promoting a greater understanding of research.

This paper presents an alternative way of working with the theme of symmetry in the elementary school classroom. The proposal is based on qualitative research developed in the Professional Masters degree program in Science and Mathematics Teaching. We conducted field-work consisting of applying a sequence of activities for students in the seventh grade. The sequence was developed from the perspective of mathematics teaching using problem solving, taking into consideration aspects relevant to the study of geometry, such as intuition and visualization. In carrying out the activities, the dialogues between students and teacher were recorded and later transcribed. For data analysis we used the procedures of phenomenology. When interpreting the data, we observed that the teaching of symmetry using problem-solving enhances learning. We also found that, in an investigative environment, students are able to identify properties, argue about the geometric characteristics, and justify their opinions.

A avaliação educacional pode ser compreendida como um campo da educação e, portanto, marcado por tensões, contradições, interesses, concepções de mundo, de homem, de sociedade e educação. Para alguns estudiosos desta temática, a avaliação transpõe as salas de aulas assumindo também uma posição central na organização e gestão do trabalho pedagógico e de políticas públicas para a educação, além de tornar-se um excelente instrumento de controle dos sujeitos que se encontram na tessitura do processo educativo. Este trabalho intentou traçar algumas percepções sobre a avaliação da aprendizagem no Curso de Graduação em Ciências Biológicas da Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP) - Campus de Rio Claro, através da ótica dos alunos dos anos finais deste Curso. Nesse sentido, buscou-se desenvolver um estudo qualitativo a partir de entrevistas semiestruturada, objetivando identificar as principais concepções e práticas sobre a avaliação da aprendizagem no curso. Os relatos indicam que a prática avaliativa, na maioria dos casos, vem adquirindo fortemente uma função somativa e classificatória, centralizada na memorização e reprodução de informações, ocorrendo quase sempre de maneira externa ao aluno e focada nos resultados da aprendizagem (produto). Pode-se dizer que a nota tem servido ora para ocultar e manter as relações hierárquicas, ora para selecionar aqueles que vão gozar de um incentivo financeiro para o desenvolvimento de outras experiências acadêmicas, resguardando uma lógica meritocrática e seletiva. De modo geral, a prática avaliativa pouco tem contribuído para a (re)organização do trabalho pedagógico pelo professor e para a superação das dificuldades e incompreensões dos alunos. Ainda que, a maioria das vivências tenha adquirido emoções negativas, as experiências mais marcantes se residem naquelas em que o aluno teve maior envolvimento e...

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.

The main objective of this survey is describing signly the metaphor learning resource, with focus on biology education. Our teorical reference is the peircean semiotics, because it means solid heritage to code surveys implicated at science education, it led us to do an explanation about the main lines about that reference, addressed to researchers and lecturers interested in those reasonings. In the description yearned, another objectives appear: demonstrate diferences between metaphor/analogy and pragmatic analogy; to list metaphors, from cell representation analysis, and argue about principals diferences and probable cognitive consequences between the metaphor event in the visual representation and speech sentences. Therefore we analysed the animal cell of a high school first grade studying book – biology – cell biology – used by São Paulo and another state students. The findings demonstrate the undeniable importance of the metaphor as a learning tool in the biology education, and new findings about that, such as its limits in the concept elaboration, gnosiologic consequences for receptioning, the search needs for propositions– pictures between concept relations – in the science speech construction, and other results.

Considering the importance that the discussion of concepts related to genetics has on the society and the necessity to approach science as a dynamic and historical activity, it will be discussed an essential concept to the understanding of biological inheritance: the concept of gene. This way, the article aims to discuss the differents concepts of genes in the history of biology and the relevance of addressing in teaching context this concept in a systemic perception of phenomena. Also, the paper have an analyses of the ideas about the concept of the gene from teachers from two university. The results indicate the presence of different definitions of the gene in the discourse of university teachers, with the predominance of gene concept as a structural, functional and/or informational unit.

We analyzed the National Curriculum for Secondary Schools with respect to the ontological, epistemological, historical, social and conceptual biology. This study aims to bring information and thinking about the inclusion of history and philosophy of biology for secondary education and for teacher training. We performed an analysis of PCNEM, PCNEM+ and Curriculum Guidelines as a whole from established categories. The results indicate a predominance of the ontological view of mechanistic biology. Epistemologically, although acknowledged, the question of scientific method is rarely discussed. The historical approach and social scientific activity and scientific knowledge are recognized by the documents, but an instrumental view prevails. The conceptual aspects are comprehensive and take into account the theories of structural biology. A philosophical discussion on the biology is missing in the parameters, indicating the need for the inclusion of issues related to ideas of determinism, chance and teleology.

In this paper, we analyze the educational importance of teaching Physics in the early grades of elementary school from a teaching experience with students of 5th grade, using five experiments on electricity and magnetism. The theoretical framework used was the socio-historical psychology, especially Vigotski's studies on concept formation. It can be stated that the teaching of Physics and the use of experimental activities in the early grades cannot be simply associated to the teaching of certain scientific concepts, but should be explored bearing in mind the child's development.

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.
