A afinidade com a Física: uma análise feita com estudantes da Universidade Federal de Mato Grosso do Sul (UFMS)

The aim of this study is to investigate aspects that influenced students of Physics at the Federal University of Mato Grosso do Sul (UFMS) to choose that course and the influence that their own teachers had on their decision. In order to do that, a questionnaire was prepared and answered by forty-five students of Physics (bachelor's course or teacher's course). In the results we highlighted that those students developed affinities with physics knowledge before choosing the course. The analysis suggests that the teacher, although not predominant in these choices, is an important catalyst, thus influencing students to choose a career in science co-operating.

Análise documental da produção acadêmica sobre o ensino de evolução (1990-2010): caracterizações e proposições

The quantitative and qualitative increasing of researches in Science teaching imposes the periodical mapping need of scientific production about the subject, with a view to identify its own characteristics and tendencies. In this context, researches such as “State of art”, given his executrix character, constitute in modality inquiring that allow us to outline historical scenes for a given area (or subarea) of knowledge. In this light, this work aims to outline the panorama of Brazilian academic production, represented by dissertations and thesis, in evolution teaching between 1990- 2010. The documents susceptible of analysis were raised in three online data basis and its selection happened from the reading of titles, abstracts and key-words with views to identify the dissertations and thesis that truly approached the Evolution Teaching. The found results evidence the predominance of dissertations related to the number of thesis and the concentration of academic production in Evolution Teaching in Brazil south-east region, especially in São Paulo state. In researches trends we verified the prevalence of investigations related to the previous conceptions of students and professors (in all teaching levels) and to teacher training.

Possibilidades e limitações da prática do professor na experiência com a temática energia e desenvolvimento humano no ensino de ciências

Reflections on the Movement STSE, in basic education, have pointed to the introduction of discussions involving the socio-scientific issues, as a way of organization and development of forming processes in science classes. In this sense, the research that we developed sought to bring to physics classes of basic education, the discussions surrounding the relationship between science, technology, society and environment issues related to production and access to electricity and human development. In order to interpret formative aspects of this approach was achieved through a short course. Thus, we discuss in this paper, the discourse of students and a professor of physics who participated in this short course. Therefore, we seek in discourse analysis, reflection on this practice, which has limitations such as lack of recognition of this type of training status by the students as well as possibilities represented by the establishment of training spaces that contribute to the discussion of socio-scientific issues.

O que sabemos sobre a pesquisa brasileira voltada à educação em museus de ciências?

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.

O tratamento de questões sociocientíficas na formação de futuros professores de ciências: possibilidades e desafios nas vozes dos licenciandos

The perspective STSE (Science-Technology-Society-Environment) was recently implemented in the training courses for science teachers in Brazil, and proposes greater coordination of scientific knowledge with subjective questions that constitute the science, enables discussion of the nature of science and its implications for social and environmental issues. The present work aims to contribute to training of science teachers that approximates the current demands of contemporary society. Having as theoretical reasons the implications of STSE Movement in science teaching, we bring some considerations on pedagogical practices of undergraduates in Biological Sciences held within its Supervised. Through content analysis of the speeches of undergraduates, we can identify contributions and limitations that treatment of socio-scientific issues (SSI) revealed in the process, putting to discuss some aspects that are tangent training teachers committed to a contextualized view of science and scientific training. It discusses, among them, the relationship theory and practice in supervised training of future teachers’ conceptions about the implications of the STSE perspective in science teaching and science teacher positioning ahead controversial themes.

Um estudo introdutório da importância da alfabetização científica para o ensino da ciência

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

Experimentação no ensino de química: propostas de realização em busca da aprendizagem significativa

The Experimentation in Science Education is used since the beginning of 19th century and has it origins linked to the laboratory classes realized in the universities. This classes used, and in many cases, still using the Scientific Method initially purposed by Descartes in 18th century for the construction of scientific knowledge. One of the allegations is that the method would be the fast stand the cheapest to generating scientific information, although, it is based on the empiricism-positivism, which considers that all people have the same learning skill and they can start from the same spot. Through this paper, is not intended to contest the scientific methodology, or even its importance in science history, but just try to identify and describe other possibilities in using of the teaching laboratory, which can make the learning easier for a much higher number of students, contemplating different cognitive capabilities and generating a better scientific knowledge learning and its transfer to practical situations in life, besides, they can provide more significant learnings. Over the text, four different purposes will be presented, which depart from the laboratory use for theory evidence, incapable to make students use the learned knowledge outside the school, until that which develops in the students capabilities to scientifically argue about their day to day themes

Cytochrome c-promoted cardiolipin oxidation generates singlet molecular oxygen

The interaction of cytochrome c (cyt c) with cardiolipin (CL) induces protein conformational changes that favor peroxidase activity. This process has been correlated with CL oxidation and the induction of cell death. Here we report evidence demonstrating the generation of singlet molecular oxygen [O-2((1)Delta(g))] by a cyt c-CL complex in a model membrane containing CL. The formation of singlet oxygen was directly evidenced by luminescence measurements at 1270 nm and by chemical trapping experiments. Singlet oxygen generation required cyt c-CL binding and occurred at pH values higher than 6, consistent with lipid-protein interactions involving fully deprotonated CL species and positively charged residues in the protein. Moreover, singlet oxygen formation was specifically observed for tetralinoleoyl CL species and was not observed with monounsaturated and saturated CL species. Our results show that there are at least two mechanisms leading to singlet oxygen formation: one with fast kinetics involving the generation of singlet oxygen directly from CL hydroperoxide decomposition and the other involving CL oxidation. The contribution of the first mechanism was clearly evidenced by the detection of labeled singlet oxygen [O-18(2)((1)Delta(g))] from liposomes supplemented with 18-oxygen-labeled CL hydroperoxides. However quantitative analysis showed that singlet oxygen yield from CL hydroperoxides was minor (<5%) and that most of the singlet oxygen is formed from the second mechanism. Based on these data and previous findings we propose a mechanism of singlet oxygen generation through reactions involving peroxyl radicals (Russell mechanism) and excited triplet carbonyl intermediates (energy transfer mechanism).

OBJETIVO: identificar, entre os cursos de Mestrado Acadêmico dos programas de pós-graduação em enfermagem brasileiros, analisados por ocasião da avaliação trienal (2007-2009) da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, a carga horária informada pelos programas para a formação de mestre. MÉTODO: trata-se de estudo descritivo, quantitativo, documental, com dados coletados em julho de 2010, mediante consulta aos relatórios da citada Coordenação, no quesito "Propostas dos Programas", dos Cadernos de Indicadores, disponíveis na web. RESULTADOS: foram encontradas discrepâncias entre as cargas horárias dos 32 cursos de Mestrado Acadêmico das diversas regiões do Brasil, sendo que a menor carga horária foi de 315 horas e a maior de 1.530 horas. CONCLUSÕES: há necessidade de maior discussão acerca da carga horária necessária à formação das competências e habilidades para o perfil desejado do egresso. O estudo propicia avanços no conhecimento da enfermagem, pois não foram identificadas investigações pregressas que tratem de tal tema. Espera-se que os cursos de Mestrado Acadêmico de enfermagem percebam-se nesse processo e revejam suas decisões pedagógicas, à luz dos novos modelos de formação/capacitação dos profissionais de enfermagem, centrados na ciência, tecnologia e inovação na área.

Análise microscópica de incisões realizadas com três diferentes pontas do laser Erbio YAG

The study analised microscopic wound healing of incision made with Er:YAg laser with three different tips. In six Rattus norvegicus, incision was made with Laser Er-YAG (KeyLaser) using tips 2051, 2055 and 2056. The animals were killed at 7 e 14 and the sites of incision are photographed in this time. The parts containing the incision area were prepared for microscopic analysis, performing sections of 7µm and staining with haematoxylin and eosin. Zone of tissue ablation, zone of thermal necrosis, the presence and character of inflammatory cell infiltrate and wound healing were measured. The 2051 tip produced faster and defined edges of the wound. To create wound 1.30 mm in depth lasers tips required at last five passes within the same line of incision. Microscopic analysis shows no difference with use of three different laser tips
