PARFOR e a formação inicial dos professores: um estudo sobre a confiança, as atitudes e as estratégias em relação à resolução de problemas

The mathematical problem solving is very important in the student's school career, leading him to develop his creativity and self-confidence. The way the teacher explains specific content may interfere in the student learning. Some researches show that the teacher trust and his problem solving rapport lead to a more satisfying job. This research focused on students of the course PARFOR at UNESP Bauru. This work was performed in order to investigate the affinity, trust and attitudes toward mathematical problem solving, the performance from who have positive and negative attitudes and the results that may be generated during class

O uso da aprendizagem baseada em problemas e a atuação docente

Recent national education policy documents have emphasized the importance of methodologies and problem-centered learning processes. The purpose of this article is to promote reflection on the problem-based learning (PBL) understood as a methodology that favors learning processes and the active role of students. PBL emerged in undergraduate medical and has been gaining ground not only in higher education but also in basic education. This conception of teaching-learning breaks with the traditional relationship teacher-student- knowledge, introducing new dynamics of relationships between subjects and those with knowledge. From this perspective the educational performance turns and brings new challenges to the teacher.

Numerical analysis of a modified evacuated tubes solar collector

The need for renewable energy sources, facing the consequences of Climate Change, results in growing investment for solar collectors’ use. Research in this field has accompanied this expansion and evacuated tube solar collector stands as an important study focus. Thus, several works have been published for representing the stratification of the fluid inside the tubes and the reservoir, as well as analytical modeling for the heat flow problem. Based on recent publications, this paper proposes the study of solar water heating with evacuated tubes, their operation characteristics and operating parameters. To develop this work, a computational tool will be used - in this case, the application of computational fluid dynamics (CFD) software. In possession of the implemented model, a numerical simulation will be performed to evaluate the behavior of the fluid within this solar collector and possible improvements to be applied in the model.

Os saberes da Educação Física nas perspectivas dos alunos: panorama da literatura e uma proposta de investigação a partir da 'teoria da relação com o saber'

The lack of interest and motivation, and the self-exclusion from Physical Education classes by Secondary and High School students is pointed out in the specific literature as a pedagogical problem for that discipline. Most studies dealing with the issue present only descriptive data, gathered from the quantification of responses given by students to questionnaires, and they lack a more consistent theoretical framework for both the generation of data as to its interpretation. The objectives of this article are: (i) to present an overview of published studies that address the perspectives of students in relation to their Physical Education classes at school, in terms of attitudes, opinions, tastes, motivation, and development; and (ii) to propose theoretical foundation and methodological guidelines for one future field based research that allows better understanding on how Secondary and High School students’ relationship to school Physical Education knowledge occurs, in order to contribute for advances regarding the results and conclusions on such thematics. We suggest that the definition of the research problem, the generation and interpretation of the data must take as reference the "theory of the notion of the relationship to knowledge", by Bernard Charlot, for whom the school knowledge must be understood in its relations with learning beings. The methodological direction should be guided by "qualitative research" general parameters in Education, using questionnaires and semi-structured interviews with students. Hopefully, in this way, indicators informed by research might contribute to improving the quality of teaching in lessons, in order to provide the students with opportunities for meaningful learning.

Contribuição à mudança curricular na graduação da Faculdade de Medicina de Botucatu

Descreve-se a inovação pedagógica de dois casos na graduação médica: uma matéria denominada Saúde Coletiva III, com (Administração, Ciências Sociais, Epidemiologia, Ética e Nutrição em Saúde Publica) e a disciplina de Semiologia Pediátrica. Para descrição e avaliação dos casos, utilizaram-se métodos qualitativos. A Saúde Coletiva III foi organizada por núcleos temáticos: Problemas em Saúde Publica; Nutrição em Saúde Publica; Planejamento em Saúde. O modelo de ensino centrou-se na problematização de situações vivenciadas na prática da Saúde Publica, trabalhando-se em centros, serviços e organizações de saúde. A Semiologia Pediátrica privilegiou a atenção integral à saúde da criança. O modelo de ensino centrou-se na aprendizagem baseada em problemas e no aprendizado prático da semiologia pediátrica em diferentes cenários, enfatizando-se o ensino ambulatorial. Privilegiou-se o trabalho em pequenos grupos, com a orientação docente. A principal missão voltou-se à utilização de estratégias que valorizassem o ensino centrado no estudante e sua capacidade de construir conhecimento com autonomia. No caso da Pediatria, avançou-se rumo a Medicina Integral, com enfoque amplo do modelo de atenção à criança. A Saúde Coletiva aproximou-se da Medicina Comunitária problematizando situações concretas no SUS e na atenção primária. O estudo mostra a possibilidade de inovação no ensino, e podendo contribuir para a mudança institucional.

A comparison of patient satisfaction between treatment with conventional complete dentures and overdentures in the elderly: a literature review

Background:It has been stated that mandibular overdentures are more satisfactory than conventional dentures, but problems relating to the use of retrospective ratings, lack of control group and sequential provision of treatment may compromise the findings.Objective:To establish a comparison between treatment with conventional complete dentures and implant-retained overdentures in elderly patients by conducting a literature review.Materials and methods:A search of English language peer-review literature was completed using Medline up to 2008 focusing on evidence-based research. Randomised clinical trials (RCTs) and longitudinal prospective studies were favoured in the review, using a general hierarchical classification. Articles that did not focus exclusively on the comparison of patient satisfaction between complete dentures and overdentures were excluded from further evaluation. The last search was conducted in February 2008. Key terms included quality of life, patient satisfaction, edentulism, complete denture and overdenture.Results:Among the 90 articles found in the initial search, 27 met the inclusion criteria. This included 18 RCTs and eight prospective and one cohort study. Most of the articles stated superiority of the mandibular implant-retained overdenture therapy over the conventional complete denture regarding patient satisfaction and quality of life.Conclusion:Even with implant treatment presenting higher patient satisfaction and improvement of quality of life, it was not possible to establish a direct comparison between the studies due to differences in adopted methodologies.

Global analysis of the post-SNO solar neutrino data for standard and nonstandard oscillation mechanisms

What can we learn from solar neutrino observations? Is there any solution to the solar neutrino anomaly which is favored by the present experimental panorama? After SNO results, is it possible to affirm that neutrinos have mass? In order to answer such questions we analyze the current available data from the solar neutrino experiments, including the recent SNO result, in view of many acceptable solutions to the solar neutrino problem based on different conversion mechanisms, for the first time using the same statistical procedure. This allows us to do a direct comparison of the goodness of the fit among different solutions, from which we can discuss and conclude on the current status of each proposed dynamical mechanism. These solutions are based on different assumptions: (a) neutrino mass and mixing, (b) a nonvanishing neutrino magnetic moment, (c) the existence of nonstandard flavor-changing and nonuniversal neutrino interactions, and (d) a tiny violation of the equivalence principle. We investigate the quality of the fit provided by each one of these solutions not only to the total rate measured by all the solar neutrino experiments but also to the recoil electron energy spectrum measured at different zenith angles by the Super-Kamiokande Collaboration. We conclude that several nonstandard neutrino flavor conversion mechanisms provide a very good fit to the experimental data which is comparable with (or even slightly better than) the most famous solution to the solar neutrino anomaly based on the neutrino oscillation induced by mass.

Pesquisa educacional com base nas artes: pensando a educação dos professores como experiência estética

Neste artigo, o autor descreve dois estudos, realizados com professores, nos quais objetos de arte são usados como dispositivos deflagradores de reflexão compartilhada. Teoricamente fundamentado em uma nova modalidade de investigação qualitativa no campo da Educação - a Pesquisa Educacional com Base nas Artes (PEBA) -, ele discute particularidades do funcionamento e do papel dessa modalidade de pesquisa no desenvolvimento profissional docente, as diferentes naturezas dos dois objetos de arte utilizados (a fotografia e o espetáculo teatral) e aponta para duas principais vertentes dessa modalidade de pesquisa - a vertente de produção de significados, pela qual o educador de professores e os participantes da pesquisa compartilham e constroem significados ao entrarem em contato com um objeto de arte previamente pronto e confeccionado por um artista profissional; e a vertente representacional, pela qual os professores e educadores participantes constroem, individualmente ou de forma compartilhada, um determinado objeto de arte que reflita e expresse suas representações do mundo da docência. Por fim, o artigo sugere que a PEBA, além de estabelecer contextos reflexivos nos quais alunos e professores têm oportunidades de desvelar a experiência estética, instaura relações alternativas dos participantes com o conhecimento e com a prática pedagógica, evidenciando sua importância social e suas forças revitalizadoras.
