O uso de atividades experimentais de demonstração para a aprendizagem de eletromagnetismo

This research aimed to verify if the use of experimental demonstration activities through an approach that employed discursive patterns that provided social interaction in the classroom, provided the students motivation to participate in activities and learn the worked contents. The students of this research were twenty four in a Guaratinguetá's school, aged between 19 and 24 years. The instruments of analysis were transcripts of conversations that occurred between student / teacher and student / student and also the studes s answers to a evaluative questionnaire. In order to support this analysis, we used the Vygotsky Social Historical theory . The results showed that the use of demonstration activities, following an approach that used discursive patterns that enabled the social interaction between teacher and students and among students, motivated students to learn the worked contents

Pluralismo metodológico e aprendizagem dos alunos no ensino fundamental

Over the years is a significant number of researchers consider constructivism as a methodology above the rest and that can be applied to any educational context, and is therefore the ideal methodology in the present moment. However, as opposed to this idea, there is a growing body of research that consider the methodological pluralism how best to teach in class, precisely because it is not just one, but several methodological practices which vary according to the educational needs of students. This exhibit features four lessons presented to students of 6th and 8th grade of elementary school II, two lessons using experimental activities, a lesson using Demo activity and a lesson using texts textbooks. In all four lessons there was a collection of data on students' understanding about the physical concepts covered by each of the above four lessons either through questionnaires, video recording, and more. Based on Vygotsky's theory of social interaction and constructs Wertsch (1984), this article raises important discussions about the advantages and disadvantages of these three methodologies within the pluralistic proposal

Ensino de lutas e educação física escolar: o caso do currículo de educação física do estado de São Paulo

O atual cenário do ensino da Educação Física no Brasil caracteriza-se como um complexo campo de conflitos, no qual emergem e embrenham-se diferentes proposições teórico-metodológicas, originadas desde meados da década de 1980 no processo histórico de emancipação, superação e ressignificação da Educação Física. Tais concepções, em contraposição ao criticado e tradicional ensino técnico-esportivista, propõe que na escola os conteúdos abordados deveriam propiciar a apropriação crítica e autônoma das diversas manifestações da Cultura de Movimento. Sendo assim, cabe analisar como os professores, autores e não meros aplicadores, lidam com mudanças curriculares. É primordial analisar criticamente as práticas pedagógicas dos professores que vivenciam e implementam tais mudanças curriculares. O objetivo desta pesquisa foi investigar como se caracteriza a relação saberes docentes-ensino de lutas entre professores da rede pública estadual de São Paulo, no cenário de implementação do currículo oficial de Educação Física. Foi realizado um estudo de natureza qualitativa; os dados foram coletados por meio de entrevistas semi-estruturadas com professores e professoras atuantes na rede pública. Os resultados evidenciaram que o déficit na formação inicial dos professores, contribuiu para o trato pedagógico superficial do conteúdo lutas em suas aulas. Com isso, dificultando o desenvolvimento do conhecimento pedagógico do conteúdo dos docentes, que atribuem sua principal fonte de conhecimentos sobre o tema a recortes oriundos da influência midiática e da proposição de atividades a partir do Currículo de Educação Física do Estado de São Paulo. Percebemos aqui, a importância da construção do conhecimento pedagógico do conteúdo, para o desenvolvimento da base de conhecimentos do educador. Acreditamos, conforme Shulman, que é de suma importância que o professor/a domine uma base de...

Genome-wide association study and ancestral origins of the slick-hair coat in tropically adapted cattle

The slick hair coat (SLICK) is a dominantly inherited trait typically associated with tropically adapted cattle that are from Criollo descent through Spanish colonization of cattle into the New World. The trait is of interest relative to climate change, due to its association with improved thermo-tolerance and subsequent increased productivity. Previous studies localized the SLICK locus to a 4 cM region on chromosome (BTA) 20 and identified signatures of selection in this region derived from Senepol cattle. The current study compares three slick-haired Criollo-derived breeds including Senepol, Carora, and Romosinuano and three additional slick-haired cross-bred lineages to non-slick ancestral breeds. Genome-wide association (GWA), haplotype analysis, signatures of selection, runs of homozygosity (ROH), and identity by state (IBS) calculations were used to identify a 0.8 Mb (37.7-38.5 Mb) consensus region for the SLICK locus on BTA20 in which contains SKP2 and SPEF2 as possible candidate genes. Three specific haplotype patterns are identified in slick individuals, all with zero frequency in non-slick individuals. Admixture analysis identified common genetic patterns between the three slick breeds at the SLICK locus. Principal component analysis (PCA) and admixture results show Senepol and Romosinuano sharing a higher degree of genetic similarity to one another with a much lesser degree of similarity to Carora. Variation in GWA, haplotype analysis, and IBS calculations with accompanying population structure information supports potentially two mutations, one common to Senepol and Romosinuano and another in Carora, effecting genes contained within our refined location for the SLICK locus.

A new heterologous fibrin sealant as a scaffold to cartilage repair - experimental study and preliminary results

Autologous fibrin gel is commonly used as a scaffold for filling defects in articular cartilage. This biomaterial can also be used as a sealant to control small hemorrhages and is especially helpful in situations where tissue reparation capacity is limited. In particular, fibrin can act as a scaffold for various cell types because it can accommodate cell migration, differentiation, and proliferation. Despite knowledge of the advantages of this biomaterial and mastery of the techniques required for its application, the durability of several types of sealant at the site of injury remains questionable. Due to the importance of such data for evaluating the quality and efficiency of fibrin gel formulations on its use as a scaffold, this study sought to analyze the heterologous fibrin sealant developed from the venom of Crotalus durissus terrificus using studies in ovine experimental models. The fibrin gel developed from the venom of this snake was shown to act as a safe, stable, and durable scaffold for up to seven days, without causing adverse side effects. Fibrin gel produced from the venom of the Crotalus durissus terrificus snake possesses many clinical and surgical uses. It presents the potential to be used as a biomaterial to help repair skin lesions or control bleeding, and it may also be used as a scaffold when applied together with various cell types. The intralesional use of the fibrin gel from the venom of this snake may improve surgical and clinical treatments in addition to being inexpensive and adequately consistent, durable, and stable. The new heterologous fibrin sealant is a scaffold candidate to cartilage repair in this study.
