Da prescrição curricular ao currículo como ação compartilhada: dilemas das tentativas de renovação dos programas de ensino de Matemática no estado de São Paulo pós-64

The present study is the result of joint actions between education, research and outreach that is focused on the training of educators and its implications for the renovation of teaching Mathematics. Its objective is to analyze the attempts to reorganize in mathematics curriculum implemented in the state of São Paulo in the post-64. It makes use of documentary analysis and interviews of teachers for reasons of discussion and conclusions. Situated in the theoretical and methodological context of collaborative research and historical-cultural theory. The research results which shows that mathematical activity is the centrality of the discussion about learning mathematics, which has consequences for the organization, of teaching programs. This is a genesis school thinking that motivates the students to the reconstruction of ideas and thinking a production process in the classroom that considers the conditions of the school, other than the conditions that governs the production of knowledge of mathematical science, which requires thinking about the formation of a teacher epistemologically curious.

Reconstruction of the gravitational wave signal h(t) during the Virgo science runs and independent validation with a photon calibrator

The Virgo detector is a kilometer-scale interferometer for gravitational wave detection located near Pisa (Italy). About 13 months of data were accumulated during four science runs (VSR1, VSR2, VSR3 and VSR4) between May 2007 and September 2011, with increasing sensitivity. In this paper, the method used to reconstruct, in the range 10 Hz-10 kHz, the gravitational wave strain time series h(t) from the detector signals is described. The standard consistency checks of the reconstruction are discussed and used to estimate the systematic uncertainties of the h(t) signal as a function of frequency. Finally, an independent setup, the photon calibrator, is described and used to validate the reconstructed h(t) signal and the associated uncertainties. The systematic uncertainties of the h(t) time series are estimated to be 8% in amplitude. The uncertainty of the phase of h(t) is 50 mrad at 10 Hz with a frequency dependence following a delay of 8 mu s at high frequency. A bias lower than 4 mu s and depending on the sky direction of the GW is also present.

História do desenvolvimento do conceito de força: um estudo visando contribuições para o ensino de física no nível médio

This study presents the results of a study on the development of the concept of force and their possible applications in physics teaching. The historical study has focused on Aristotelian natural philosophy, medieval theories of strength in impressed and on classical Newtonian mechanics. The Newtonian concept of force was also an object lesson of physics analyzed in this study. In this lesson, conducted in a preuniversity course, spontaneous conceptions or alternative conceptions of students about the concept of force proved very entrenched, resulting in studies on the Model Change on Conceptual and epistemological obstacles in view Bachelardian. The theoretical frameworks adopted led us to trace parallels between spontaneous conceptions revealed by the students and some views about the concept of force found in the study of history. The results show that while some old conceptions have been replaced by scientifically Newtonian concept of force, they are still present in the students' ideas and resist to changes even after the study of Newton's laws. Like main result shows that the history of science can be a great ally for the deconstruction of alternative conceptions, particularly when these concepts were previously presented and overcome the course of history of the development of a concept

O modelo atômico de Bohr e as abordagens para seu ensino na escola média

The teaching of modern and contemporary Physics subjects in high school is indispensable and it was already justified by several researchers. Among the subjects which must be taught, there is, for instance, Bohr atomics model. However, as it was noticed in literature review, many didactic materials do not deal with this model adequately, since that they do not take into account Bohr ideas, which involved Planck studies on black-body radiation, Einsten theory for photoelectric effect, Rutherford experiences and atomics model and the empiric results upon the spectrums of chemical elements emission. From that, it is extremely important teaching through approaches which potentialize the learning of the model proposed by Niels Bohr. On the other hand, teachers from high schools cannot have clearness about which approaches can be applied for teaching the mentioned model. Thus, it is presented some possibilities for teaching Bohr atomics model, with examples and justifications for the use of each one. Special treatment was attributed to the teaching from Science History and Philosophy, from the reading of scientific diffusion and original scientific texts, from analogies, from comic strips and from computer simulations.

Desencantamento do mundo e ética na ação pedagógica: reflexões a partir de Max Weber

This article has a theoretical character and presents some of Weber's ideas, with emphasis on those that can supply elements to reflect on the current state of education, more particularly based on his understanding of modernity. Disenchantment of the world is the key concept in his sociology, and is taken as the basis for a reflection about the meaning that science and the teacher can have today. A classic author, Weber's interpretation of the modern world brings to our consideration a variety of themes that influence markedly the thinking and practice of contemporary culture by its concern with understanding human actions and values. By studying the Western process of rationalization, he initiates debates in science, in ethics and, correspondingly, in education, allowing us to expand our comprehension of the meaning, significance, and role of our actions towards knowledge and teaching. The main object of education is to offer students contents that stimulate the freedom of thought. For that, the teacher needs to adopt a non-partisan ethics in the classroom, presenting contents unbiased by her/his political opinions and, if failing to do so, having the honesty to explain what she/he is doing. It is therefore of the utmost importance that the teacher should keep a neutral position, so that in and out of the classroom the students may reflect and question what they see, experiment and decide upon. Only then the conduct of the teacher will be consistent with the process of rationalization of our culture.

Concepciones de futuros profesores de biología, brasileros y portugueses sobre valores eticos de la ciencia

One of the science education objective, based on relationships between science, technology, society and environment (STSE) is, to form citizens capable on evaluating and taking decisions about the scientific advances impact on society and environment. In a two-way perspective, understand relationships between STSE, provides a vision of science as a human construction and therefore fallible, changeable and not neutral. In this study, we present some results from a comparative study on the influence of ethical conceptions of the nature of science, in two groups of future biology teachers, one from Brazil and, another one from Portugal. For data collection we constructed an attitude scale of Likert-type, which was validated mathematically and semantically. Results shows strong influence of social values, as in transgenic products, where the students’ ideas varied according to the ethical discussions more present in each country.

Diversidade religiosa e formação de professores de ciências: uma discussão em Habermas e um caso no ensino de Física

This article brings a discussion of the implications of religious diversity on science education as well as on teacher education. To orientate our discussion, we adopt as framework the ideas of German philosopher Jürgen Habermas on the political relationship that should govern relations between a naturalistic culture and different religious cultures. We also present a research with future teachers of physics, which aimed at investigating the positions taken by the future teachers towards non scientific models presented by students about the origins of the universe. We tried to identify, especially, the expectation of these future teachers would demonstrated about the contributing of the lifting of such models in class by students. We were able to find that most of them believe that the manifestation of these ideas could bring contributions to the discussion in the classroom. We also found that teaching practices based on communication, questioning and dialogue of the undergraduate course done by the prospective teachers has generated an ownership by the undergraduates of these practices and their potential application in other situations and other discussions, including inter-religious.
