História da ciência como estratégia didática no ensino médio: um breve olhar de conteúdos da óptica

From a critique of aspects of the current teaching of physics, we propose in this paper an investigation into the conceptions of Nature of Science (NOS) submitted by students from the high school level, as well as the inclusion of discussions about some elements of NOS, through the History and Philosophy of Science, understanding them as facilitating strategy for more effective learning of Physics and, more specifically, the contents of optics. Based on the historical period corresponding to Greek antiquity to the mid-nineteenth century, built and applied a teaching unit to a high school class at the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) Ipanguaçu campus. Our teaching unit involved the reading and interpretation of texts with historical content, observation and assembling five experimental activities, among other activities. Data analysis occurred through questionnaires investigative applied before and after the completion of the teaching unit, as well as questionnaires for content present in the texts. Although not significant, the results indicated that the application of the teaching unit allowed the (re) construction of some conceptions about NOS targets students present in our work, and contribute to a better learning content and greater optical science approach and its nature

História da ciência, interdisciplinaridade e ensino de física: o problema do demônio de Maxwell

Propomos que uma evolução de idéias científicas seja usada como instrumento de aprendizagem de conteúdos específicos e, em particular, para ressaltar como os conteúdos se articulam entre as disciplinas. Como exemplo, apresentamos um estudo sobre a proposta do demônio de Maxwell e discussões sobre sua exorcização, isto é, um estudo sobre a compreensão da natureza de um ser inteligente que atua dentro de um sistema físico e de como seria essa atuação. Estão envolvidos nesse problema fenômenos relacionados com várias teorias - Termodinâmica, Física Molecular, Mecânica Estatística, Teoria da Informação - dentro das disciplinas de Física, Química, Biologia, Computação. Entre diversas questões epistemológicas e conceituais aí contidas, será enfatizada a questão do objeto limitado de uma eoria científica, isto é, da limitação de seu significado aos fenômenos por ela compreendidos. A delimitação dos fenômenos estudados e as teorias e técnicas caracterizam a compreensão que vai realizar sua emergência concreta nos laboratórios. Essa compreensão vai dar também a possibilidade de atuação interdisciplinar.

História da ciência no ensino de Física: um estudo sobre o ensino de atração gravitacional desenvolvido com futuros professores

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.

Inércia e Natureza da Ciência no Ensino de Física: uma sequência didática centrada no desenvolvimento histórico do conceito de inércia

During the last decades the area of science education has discussed issues related to the inclusion of the History and Philosophy of Science (HFS) in the practice of science teaching. Among the arguments put forward in favour of this approach, it is pointed out the possible enhancement of scientific content learning and the understanding of the nature of Science (NoS). In spite of such considerations, we still have a very small number of research papers reporting results of practical interventions that utilize the historical approach, moreover, there is a lack of teaching materials in this perspective. Our work has sought to contribute to this area with regard to two aspects: on the one hand, with the production of didactic material, by drawing up texts on the history of inertia for graduate students. On the other hand, we investigate whether the arguments mentioned above in relation to the didactic use of HFS sustain themselves, in a particular context. We developed and applied a didactic sequence, using the texts that we built, to teach the concept of inertia and discuss selected contents of NoS. The didactic sequence was applied in two graduate classes, one from a course of Geophysics (BSc.) and another from the Physics (teaching formation), both from the Federal University of Rio Grande do Norte (UFRN). An initial survey exposed that students, even having approached the concept of inertia in basic education, presented conceptions of common sense regarding the relationship between force and motion. The questionnaire also allowed us to identify the existence of elements of concepts considered inadequate as regards to NoS. At the end of our research, our data indicated a greater number of positive hits on the issues concerning the concept of inertia. Regarding the aspects of NoS, we were able to identify, in a few cases, a move towards a more appropriate understanding, however, certain distortions persisted, highlighting the limitations of the approach used

O desenvolvimento de habilidades argumentativas no ensino médio: perspectiva a partir de um minicurso investigativo com base na história da ciência

The performance of investigative activities with lessons in teaching Science and Chemistry has promoted meaningful learning of scientific knowledge. This study aimed to develop the links between higher education for research and skills argumentative, aimed at building the scientific concept on combustion of the candle in a closed container, for students from two classes of 3rd year of high school, two city schools Bauru, São Paulo. We decided to do a short course investigative, to respond argumentative skills which are developed during the minicourse using investigative activities, knowledge from the history and philosophy of science. The results were gathered from analysis of video recordings of episodes of the short course in both the groups, to produce a higher rate of use of argumentative skill, which were classified into categories according to the prior knowledge of the subject, 'factual knowledge' , 'understanding of concepts' and 'reasoning and analysis.' From the information obtained, it was found that both the teachers and the students were consistent in their actions, and that the activity of reasoning is key to learning. Thus, one can realize that knowledge is not acquired all at the same time, each individual depends on the mediation of the teacher in order to reach different design more appropriate teaching and investigative linked with the argument can be the key tool to acquire this knowledge

Investigando a presença da história da ciência em livros didáticos de Química Geral para o ensino superior

This paper aims at analyzing the history of science content of three general chemistry textbooks used in Brazilian universities: the translations of Kotz and Treichel's Chemistry & Chemical Reactivity, Atkins and Jones's Chemical Principles, and Garritz and Chamizo's Química. Results revealed different trends for the inclusion of history of science in chemistry teaching. Kotz & Treichel and Atkins & Jones used history mainly as curiosity and ornament. Garritz & Chamizo adopted the historical approach as one of the organizing axis of their textbook. Nevertheless, the historical content of the three textbooks may be criticized from current historiographical standpoint.

Prototexto, narrativa poética da ciência: uma estratégia de construção do conhecimento e religação de saberes no ensino de física

In this thesis I present the prototexto notion and to I base as a complex system while strategy of knowledge construction and reconexion of you know in physics teaching. Prototexto is a poetic narrative of the science, proposal and used initially as "instrument of creative" learning for students apprentice of science of the medium and technical teaching of the Vitória da Conquista's CEFET-BA, in the period of 1997-2004. Later become pregnant as a strategy of knowledge construction, in the Universidade Estadual da Bahia - UESB, the prototexto notion configures a complement to the mathematical formulation. The proposal of a poetic narrative of the science is that the apprentice of science starts to organize in an aesthetic-literary way your knowledge, dispersed in disciplines, starting from a theme of the physics. The prototexto emerges of my reflections concerning the classic science, identified for Edgar Morin as tends a thought excessively numeric, and that it has been reproduced in physics teaching, in most of the schools, limiting him/it to an order pattern with the mistake absence. They are operations of the prototexto: the poetic language, the pedagogic stamp, the unfinished of the argument, the system character and the apprentice's of science inclusion as subject implicated in the construction of the knowledge. the theoretical foundations are based Morin's proposition of the method as strategy, the beginning of the complementarity of Niels Bohr in conceiving excluding categories as face of a same phenomenon and the conception of creative time of Ilya Prigogine that enunciates the alliance among the nature and the man that it describes her

A história da ciência na formação do professor de física: subsídios para um curso sobre o tema atração gravitacional visando às mudanças de postura na ação docente

O objetivo desta pesquisa foi estudar como a evolução histórica dos modelos de atração entre corpos, tendo como pano de fundo a evolução dos modelos de mundo, pode auxiliar na formação inicial do docente de Física. Para tanto, sugerimos um planejamento de curso sobre o tema atração gravitacional, destinado principalmente a docentes de Física que atuam no ensino médio. O planejamento do curso foi baseado: em dados sobre a evolução dos modelos de mundo, buscando evidenciar como o conceito de atração gravitacional desenvolveu-se historicamente; nas concepções alternativas mais comuns encontradas na literatura, incluindo um breve esboço de noções diagnosticadas em uma amostra de docentes de Física de ensino médio; e em sugestões de leituras de resultados de pesquisas recentes sobre os processos de ensino e aprendizagem de ciências. Pretende-se fornecer aos docentes elementos de reflexão que lhes proporcionem mudanças de postura, através do questionamento da visão de ciência enquanto processo de construção e sobre sua própria prática de ensino. Partindo de resultados recentes da pesquisa em Ensino de Ciências, a metodologia sugerida privilegia o trabalho coletivo, com a realização de debates e sínteses. As atividades mencionadas são acompanhadas de justificativas sobre a escolha do tema e objetivos.
