Propriedades dos sistemas de numeração: uma sequência didática em uma abordagem histórica

This paper aims to describe the construction and validation of a notebook of activities whose content is a didactic sequence that makes use of the study of ancient numbering systems as compared to the object of our decimal positional numbering system Arabic. This is on the assumption that the comparison with a system different from our own might provide a better understanding of our own numbering system, but also help in the process of arithmetic operations of addition, subtraction and multiplication, since it will force us to think in ways that are not routinely object of our attention. The systems covered in the study were the Egyptian hieroglyphic system of numbering, the numbering system Greek alphabet and Roman numbering system, always compared to our numbering system. The following teachung is presented structured in the form of our activities, so-called exercise set and common tasks around a former same numbering system. In its final stage of preparation, the sequence with the participation of 26 primary school teachers of basic education

Atividades estruturais de equações polinomiais numa abordagem histórica por meio de e-book

The present study investigates how the inter-relationship of the content of polynomial equations works with structured activities and with the history of mathematics through a sequence of activities presented in an e-book, so that the result of this research will proceed will result in a didactic and pedagogic proposal for the teaching of polynomial equations in a historical approach via the reported e-book. Therefore, we have considered in theoretical and methodological assumptions of the History of Mathematics, in structured activities and new technologies with an emphasis on e-book tool. We used as a methodological approach the qualitative research, as our research object adjusts to the objectives of this research mode. As methodological instruments, we used the e-book as a synthesis tool of the sequence of activities to be evaluated, while the questionnaires, semi-structured interviews and participant observation were designed to register and analyze the evaluation made by the research, participants in the structured activities. The processing and analysis of data collected though the questionnaires were organized, classified and quantified in summary tables to facilitate visualization, interpretation, understanding, and analysis of these data. As for participant observation was used to contribute to the qualitative analysis of the quantified data. The interviews were synthetically transcribed and qualitatively analyzed. The analysis ratified our research objectives and contributed to improve, approve and indicate the use of e-book for the teaching of polynomial equations. Thus, we consider that this educational product will bring significant contributions to the teaching of mathematical content, in Basic Education

O processo de constituição histórica das diretrizes curriculares na formação de professores de Educação Física

Os processos históricos que permeiam as diretrizes curriculares possibilitaram enxergar quais são as idéias e as preocupações para com a formação de professores no âmbito da Educação Física. Dentro desse contexto, o objetivo foi averiguar, nas políticas públicas de formação de professor dessa disciplina, como ocorreu o processo de qualificação e certificação, buscando entender as justificativas que orientaram a regulamentação dos normativos legais de 1939 a 2004. Portanto, trata-se de um estudo descritivo, de análise qualitativa, tendo como fonte primária as Diretrizes Curriculares veiculada pela imprensa oficial. As novas Diretrizes Curriculares (Resoluções CNE/CP 01/2002, 02/2002 e 7/2004) apontaram perspectivas na formação de um professor mais qualificado para o seu campo de atuação, priorizando a questão da dimensão política da profissão, das competências e do corpo de conhecimento da área. Embora haja progressos em relação aos normativos anteriores, chama-se atenção para a necessidade de que as propostas em construção façam a mediação entre a proposta atual, o percurso histórico do próprio curso e a relação teoria-prática, visando o equilíbrio na formação. A proposta das novas diretrizes não deixa de evidenciar avanços significativos no horizonte da profissionalidade docente e da identidade profissional docente. da mesma forma, para o leitor ou estudioso atento, não deixa de causar preocupação o excesso de competências técnicas colocadas, passando-se a impressão de que agora o que vale é o primado do saber fazer.

Um lugar (in)existente: o "país" de Mossoró" nas tramas da consciência histórica

This work aims to analyze, on the one hand, how the academy has created the spatial term the country of Mossoró and, on the other hand, is to discover, by the teachers testimony, how the History teaching works with this spatiality. The academic production in Mossoró-RN, particularly during the last two decades of the century XX, focuses on the practices that built a historic memory based on political interests of the Rosado family. Therefore, this work is divided in three chapters. In the first one, we identify how the academic production has created a group of meanings related to the country of Mossoró , because it is a way to realize how this place is seeing and understand. In the second one, there is an explanation about the ideology concepts, that structure meanings created by the academic production, as well as the historic conscience that is used to think about the dynamic of teaching History. In the third, we analyze how teachers, expressing their historic conscience, figure meaning to this country of Mossoró

Educação científica e atividade grupal na perspectiva sócio-histórica

Este trabalho apresenta questões relativas à educação científica e à atividade grupal ou coletiva, na perspectiva da abordagem sócio-histórica do desenvolvimento humano e do ensino científico presente nas obras dos russos L.S. Vigotski e A.N. Leontiev. Fundamentalmente, buscaremos estabelecer essa relação a partir da proposta de Zona de Desenvolvimento Próximo realizada por Vigotski, em que o autor enfatiza o papel da imitação e da cooperação no alcance de novos níveis de desenvolvimento, processo subsidiado pela instrução, tendo como mediação o educador.

Antropologia da doenca e do doente: percepcoes e estrategias de vida dos tuberculosis.
