A inovação pedagógica na aprendizagem de matemática numa perspectiva etnográfica

Objetivou-se conhecer a maneira pela qual vem se desenvolvendo uma prática pedagógica inovadora na aprendizagem de Matemática, na perspectiva da etnoMatemática, que supere o distanciamento entre teoria e prática e contribua diretamente para a construção e apreensão de conceitos matemáticos significativos e aplicáveis coerentemente no cotidiano dos alunos. Utilizou-se para esta pesquisa uma abordagem qualitativa com estudo de caso tipo etnográfico, realizado no Colégio Municipal 11 de Novembro em Nova Russas no Estado do Ceará - Brasil, precisamente no 9º Ano, com uso de diversos instrumentos, tais como: documentos da escola, diário de campo e questionários implementados com o núcleo gestor, professor e alunos, sendo os resultados analisados conforme o discurso dos participantes. No que concerne a inovação pedagógica voltada para o ensino da matemática, a escola analisada já vivenciou um projeto denominado Gestar II. Por meio deste projeto a professora de matemática foi apresentada a novas formas de apresentação do conteúdo, foi estimulada a educação permanente, passou a perceber o aluno como um ser único e a relevância da relação teoria-prática. Em relação aos resultados do núcleo gestor o mesmo descreveu a melhora nos índices dos alunos, como assiduidade e maior aprovação, efeitos obtidos pela implementação de aulas diferenciadas e socialização das atividades. No contexto dos alunos em sua maioria descreveram que o ensino da matemática torna-se mais interessante pela adoção de ferramentas de aprendizagem e da aliança entre teoria e prática. Conclui-se que a inovação pedagógica voltada para o ensino da matemática é um recurso relevante, porem há alguns desafios a serem superados para consolidação destas novas práticas. Esta pesquisa oferece um suporte teórico e científico-prático sobre este assunto para despertar nos interessados a inquietação pelo tema, principalmente, a vontade incessante de transformar a educação da atualidade.

...Em busca da realidade... : a experiência da etnicidade dos Eleotérios (Catu/RN)

The south region of the Rio Grande do Norte has been historically recognized as a place of old indian villages. Inhabitants of the edges of the Catu River, border between the cities of Canguaretama and Goianinha, the Eleotérios in the threshold of 21st century had passed to be seen and self recognized as "remaining indians" of the RN. Their ethnic mobilizations, when becoming public had placed to the intellectual and political fields an old question to be reflected on: the asseverations concerning the "indian disappearing" in the State. This item brings with it other implications. Accessed by a para-oficial indigenism, the Eleotérios had started to establish political relations with the Potiguara indians of the Baía da Traição/PB and the Indian Movement, feeling stimulated to produce and to reproduce forms of social differentiation. In this context, this research is worried about elucidating the process of construction of the ethnicity among the Eleotérios, percepted from the social relations and politics kept with the amplest society, into a particular historical situation involving sugar cane fields owners, proprietaries, militants, researchers, ambiental agencies. The effects of these political and social relations had been extended, making Eleotérios appear to the society as susceptible social actors to the specific policies for the aboriginal populations

Análise das interpretações do governo Evo Morales: o legado histórico e o poder nacional-indígena

This work aims to analyze the interpretations about Evo Morales' government in Bolivia. For such, it proposes a theoretical reclaim of Marxism in Latin America, as well as of Bolivian political history since the 1952 Revolution, going through the crisis in Pacted Democracy intensified in the five-year conjuncture of struggles started in 2000 up to the election and reelection of Morales. It departs from an empirical prior conjecture taken from a qualitative analysis and a broad literature review to analyze the different interpretations of the Bolivian political process from Marxist theoretical matrices. After this historical recovery and this reading of contemporary Bolivia, it concludes with a consideration about the formation of a possible new block of power in the country, with the retaking of nationalism and Indianism as revolutionary reasons

Saberes e práticas etnomatemáticas na carcinicultura: o caso da Vila de Rego Moleiro-RN

This study addresses issues related to the mathematical knowledge and practices of the workers of carcinoculture (shrimp farming), associating such knowledge and practices to the conceptual aspects and the academic mathematical language. Our central aim was to investigate and discuss such knowledge and practices in order to contribute towards having the members of this group reflect upon their own working practices. The investigation took as reference the ethnographic research approach during observations and interviews, as well as the analysis and interpretation of the existing cultural aspects on the use of Mathematics in the shrimp farmers daily activities, thus composing the four chapters of this dissertation. Initially, the local-regional context was set in the area where the workers of the shrimp farm reside, also describing our methodological options. After that, the kind of work that was carried out is explained through a brief history of the shrimp-farming activity, including a short discussion on the environmental impacts that result as a consequence of shrimp-farming. We then discuss some theoretical and practical aspects of the Ethnomathematics while field of study and research. At that moment, we make a reflection upon the different kinds of Mathematics, especially stressing the kind of Mathematics being taught in Schools and that being put to practice by identifiable cultural groups. With that in mind, we show the investigated knowledge and practices e some possible systematizations accomplished during the study. In the end, we point out some conclusive propositions based on the implications of our study towards the development of an educational process within the local communities, considering a possible use of the results and conclusions of this study in the classroom activities

A cultura da produção de farinha: um estudo da matemática nos saberes dessa tradição

This research argues about the mathematical knowledge built in the tradition of the cassava flour production, seeking to analyse these mathematical knowledge in the perspective of the categories of time and measure, built and practiced in the flour production, located in Serra do Navio and Calçoene, in Amapá - Brazil. The following work discuss the identification and the description of the mathematics during the production activities of the flour, where is presented elements related to generation and transmission of the traditional knowledge, which is the basis for maintenance of the tradition of the flour, characterizing the research as an Ethnomathematic study. The methodological procedures highlight ethnographical techniques and elements that characterize the participating observation. The results obtained showed us that the flour workers articulate some length, area and volume measure due to own and traditionally acquired systems, which is apprehended and countersigned by other kind of culturally established system; thus they relativism the measures systems and the official calendars. And it lifts as one of the main proposal that the academic mathematics and the tradition establish knowledge make conjunction of the both knowledge, that is important for a possible reflection and application in the construction of a pedagogical practice in mathematical education, trying to establish points of socio-economic and cultural mark

Objetiva(ação) da medida e contagem do tempo em práticas socioculturais e educativas

This thesis describes and analyzes various processes established and practiced by both groups about the socio-cultural objective (action) the measurement and timing, mobilized some socio-historical practices as the use of the gnômon of the sundial and reading and interpretation of movements celestial constellations in cultural contexts such as indigenous communities and fishermen in the state of Pará, Brazil. The Purpose of the study was to describe and analyze the mobilization of such practices in the socio-historical development of matrices for teaching concepts and skills related to geometric angles, similar triangles, symmetry and proportionality in the training of mathematics teachers. The record of the entire history of investigation into the socio-historical practice, the formative action was based on epistemological assumptions of education ethnomathematics proposed by Vergani (2000, 2007) and Ubiratan D'Ambrosio (1986, 1993, 1996, 2001, 2004) and Alain Bishop conceptions about mathematics enculturation. At the end of the study I present my views on the practices of contributions called socio-cultural and historical for school mathematics, to give meaning to the concept formation and teaching of students, especially the implications of Education Ethnomatematics proposed by Vergani (2000) for training of future teachers of mathematics

Educação matemática, ciência e tradição: tudo no mesmo barco

Les connaissances de la tradition et position de la Science dehors pour un non-hiérarchique dialoguez qui frappe pour les distinguer mais ils sont undésavouer inséparable étant donné les compléments ils composent. Cet essai assume la possibilité de ce roi de dialogue dans un place spéciale: la classe. Sur ce qui vient au connaissance de la tradition, le centre remarquable est pour la construction de bateaux du travail manuel, una pratique culturellement déployé dans la ville d'Abaetetuba, dans le État de Pará, Brésil. En revanche, la Science est concentrée par le le contenu d'école a adopté dans l'Ensino Fundamental (École primaire). La construction du dialogue est faite en utilisant des activités de l'enseignement qui accentuez des aspects géométriques (solide, géométrique, angles et symétries) aussi bien que par information qui implique le tableau, poésie, histoire, géographie et physique - les deux inspiré dans le chiffre de bateau résumé dans un CD-ROM interactif. Les activités ont eu lieu dans D'Escola Ensino Pedro Teixeira Fondamental (Abaetetuba-Pa), avec étudiants du 6e niveau (plus spécifiquement avec un groupe de 13 étudiants) d'août à octobre2004. Ethnomathématiques et transdisciplinarité sont le support théorique sous-jacent du projet. Dans résumé, c'est possible pour dire que l'interaction entre Science et Tradition, à travers activités au-delà lesquelles vont le le contenu a restreint à mathématiques d'école, contribuées à,: identifiez le contenu a appris pas sur dans série antérieure; renouveler le rôle joué par école dans ses fonctions didactique pédagogiques; réduire le isolement entre information passée historique et les étudiants présent culturel; indiquer des obstacles à l'érudition des mathématiques intéresser aux aspects cognitifs et behavioristes; et provoquer un participation affective qui rôle principal à la qualité d'apprendre l'école contenu aussi bien que les connaissances de la tradition

Simetria na dança: vestígios matemáticos na prática da dança esportiva em cadeira de rodas

To investigate in practice of the Wheelchair Dancesport (WDS), the mathematics of the characteristic isometric movements of the dance of ChaChaCha was the generating subject of this study. The subjects and the locus of the research were the athletes dancers of the Associação Baiana de Dança em Cadeira de Rodas (ABDCR). Referred him study aimed at to describe reflections concerning the athletes' practicing dancers of the technical acting Wheelchair Dancesport, using the inherent mathematical knowledge to the isometric movements executed in the ChaChaCha. For that, I stimulated in the athlete dancer the need to be investigating of his/her own practice, motivating him/it to be searching of information that they collaborate with his/her technical refinement, proposing like this roads to make possible his/her growth, while dancer and, also, promoting of their own movements. To reach my objectives I dialogued with some specialists to understand, to the light of their theories as, Espaçonumerática, Sociology of the mathematics, Etnomathematical, Dance and Symmetry, as those spaces they interact with the atmosphere of the Wheelchair Dancesport and that contributions could supply to the study. However, two authors of the Dancesport for walking , Ried e Laird, they brought contributions that aided in the creation of a prototype for the study of isometric movements in practice of the modality promoting the interface between the theory and the practice. The study showed to be possible to navigate still with the Mathematical Education in an universe little known as the one of the Wheelchair Dancesport. And it is in this adapts that propose a more attentive glance to the illustrations executed by the athlete dancer wheelchair and walking , in the dance of the ChaChaCha, verifying and proposing an analysis with focus investigate, looking for mathematical tracks concerning the symmetry that you/they characterize some of their illustrations

Práticas etnomatemáticas no Liceu do Paracuri :a propósito dos ornamentos geométricos da cerâmica

The present study analyzes the ethnomatematics practices presents in the creation of the geometric ornaments of the icoaraciense ceramic, originated and still practiced in the neighborhood of Paracuri, District of Icoaraci, belonging to Belém, capital of the State of Pará/Brasil. The object of our study was centered at the workshops supplied by the artisans master of the School of Arts and Occupations, Master Raimundo Cardoso. Referred school provides to its students, formation at fundamental level as well professional formation, through vocational workshops that help to maintain alive the practice of the icoaraciense ceramic. Our interest of researching that cultural and vocational practice appeared when we got in touch with that School, during the development of activities of a discipline of the degree course of mathematics. In order to reach our objective, we accomplished, initially, a research about the icoaraciense ceramic historic, since the first works with the clay until to the main characteristics of that ceramic. Soon afterwards, we discussed on ethnomatematics, culture, knowledge, cognition and mathematical education. At the end, we analyzed the creation of the geometric ornaments of the icoaraciense ceramic, considering the proportion concepts, symmetry and some geometry notions, that are used by the artisans when they are ornamenting the pieces of that ceramic. We verified that, in spite of the artisans, usually, do not demonstrate to possess a bit of domain on the mathematical concepts that they are working with, for instance, the ones of translaction symmetry, rotation and reflection, they demonstrate full safety in the use of those concepts, as well as the capacity to recognize them, even if in a singular specific and very peculiar way, what opens the possibility of a partnership among mathematics teachers and master-artisans of the archeological ceramic and icoaraciense workshops
