Place et rôle des technologies dans l'enseignement et l'apprentissage du calcul soustractif en CE2 : proposition d'ingénierie / Place and role of technologies In the teaching and the learning of subtraction : engineering suggestion

Rinaldi, Anne-Marie 05 December 2016 (has links)
Notre recherche conduite dans le cadre de la Théorie Anthropologique du Didactique, nous a menée, suite à une étude épistémologique et didactique, à construire une organisation mathématique de référence autour du calcul soustractif. Cet outil théorique permet d’avancer, en analysant différents manuels scolaires de CE1 et de CE2, et des séances de calcul observées dans des classes de CE2, qu’un déficit en éléments technologiques, expliquerait en partie, les difficultés rencontrées par les élèves pour développer de la flexibilité et de l’adaptabilité en calcul mental et pour effectuer un calcul posé en colonne. Par ailleurs, l’évaluation de l’ingénierie que nous avons conçue, en nous appuyant sur L’organisation mathématique de référence et en restant « assez proche » des pratiques des enseignants, montre les effets positifs d’un travail régulier et progressif à partir des écritures arithmétiques sur les apprentissages des élèves. En revanche, les expérimentations permettent de pointer les limites des situations qui mettent en jeu la propriété de conservation des écarts quand celles-ci, n’engagent pas assez l’élève dans une co-construction du savoir. En ce sens, la thèse peut servir d’appui pour poursuivre la recherche engagée sur les conditions de viabilité d’une organisation didactique susceptible de fédérer le calcul mental et le calcul posé / Our research made for the sake of Didactics Anthropological Theory led us, after a didactical epistemological study, to build a mathematical organization of reference around subtractions. This theoretical tool permits us to progress, by analyzing different school books of CE1 and CE2 as well as maths sessions observed in classes of CE2, that a deficiency in technological elements , would explainin part, the difficulties faced by pupils when developing flexibility and adaptability in mental calculation as well as when performing a calculation put in a column. Furthermore, the evaluation of the engineering that we have designed basing ourselves on the reference of mathematical organization and by staying « quite close » to the teachers practices shows the positive effects of a regular and progressive work from the arithmetical writings on the pupils learning. On the other hand, the experiments allow us to point out the limits of the situations that involve the propriety of the conservation of differences when these don’t engage enough the learnerin a co-construction knowledge. In this sense, the thesis can serve as a support to continue the research engaged on the viability conditions of a mathematical organization as well as a didactical organisation susceptible of federationg mental calculation and vertical calculation.

The aesthetics and politics of Ojibwe language revitalization

Uran, Chad Scott 01 December 2012 (has links)
This is an investigation into language ideologies, and the significance of same, among activists working to revitalize the Ojibwe language. Better inclusion of indigenous community members is necessary to spread the Ojibwe language. Improved competence in using--and strategically chging--language ideologies is necessary by language activists. Matters of orthography, storytelling, Elder status, state institutionalization, indigenous leadership, and decolonization reveal underlying ideologies of language, any of which can help or hinder efforts to reverse language shift. This is shown through participant observation in and around an Ojibwe language immersion school in Wisconsin.

DOING JUSTICE: STORIES OF EVERYDAY LIFE IN DISADVANTAGED SCHOOLS AND NEIGHBOURHOODS

Thomson, Patricia Lorna, kimg@deakin.edu.au January 1999 (has links)
I worked as a school administrator in 'disadvantaged schools' for many years. In this study I asked colleagues from sixteen schools in the northern and western suburbs of Adelaide to co - theorise about changes in their neighbourhood, school populations and programs, now that their schools are no longer recognised by policy as 'disadvantaged1. I explore the use of narrative method and arts based approaches by constructing a 'literary' research text that uses conventional sociological forms together with images, poetry and personal stories. I use anthropological and geographical theoretical constructs to look at the changing material, economic, cultural and social landscapes and the mosaic of inequalities in the city of Adelaide. I suggest that this is not a simple binary polarisation, although large numbers of people are similarly positioned by de-industrialisation and the diminishing social wage. After examining the literature on poverty in Australia, I am eventually prepared to call this space class, understanding that this is a sociological metaphor. Through a theorisation of each school as a 'place' within a specific neighbourhood, I look at the similarities and differences across sites. I suggest that 'disadvantaged schools' are similarly positioned as sites for the mediation of social inequalities, and that this can be readily seen in the time consuming 'housework' of discipline and welfare. I indicate how each school is differently able to 'do more with less', because of their unique neighbourhood and its narratives, knowledges, histories, teleologies and people. I show that the common coercive regimes of market devolution, new public management and the 'distributive curriculum' frame the work of teachers, students and administrators in ways that are not conducive to 'doing justice', despite the policy rhetoric of equity and community. I provide evidence that the neoliberal imaginary of context free schooling enshrined in effective schools literatures is Utopian and irrational. I argue that the capacity of the school to 'generate context' is always paradoxically dependent on 'context derived'. I discuss the notion of 'doing justice' and the benefits of 'disadvantaged schools' having a local set of principles that guide their decisions and actions and provide evidence that the school administrator's understandings of 'doing justice' are important. I also suggest that, despite being increasingly isolated and hindered by policy directions, the majority of the sixteen schools continue to work for and with principles of justice and equity, drawing on a range of emotional and intellectual resources and deep, longstanding commitments. I conclude by speculating on the kinds of policy and research agendas that might take account of both the commonalities and differences amongst 'disadvantaged schools', and what might be included in a comprehensive and systematic approach to 'doing justice'.

Place et rôle des grandeurs dans la construction des domaines mathématiques numérique, fonctionnel et géométrique et de leurs interrelations dans l'enseignement au collège en France / The place and role of magnitudes in the development of different mathematics fields numeric, functional and geometric and in their interrelations at school in France

Anwandter-Cuellar, Nathalie 25 May 2012 (has links)
Cette recherche propose d'étudier la place et le rôle des grandeurs dans la construction des différents domaines mathématiques et de leurs interrelations au collège. Elle s'inscrit dans le cadre de la théorie anthropologique du didactique développée par Yves Chevallard. Une analyse épistémologique des savoirs mathématiques relatifs aux grandeurs nous a permis d'examiner les choix institutionnels et leurs effets sur l'enseignement. Nous complétons ce travail par une étude écologique et praxéologique des programmes, et des documents institutionnels actuels pour caractériser les rapports institutionnels aux grandeurs. Une méthodologie du type clinique est mise en œuvre pour analyser le savoir enseigné concernant les grandeurs dans des classes de 6e et 5e en France. Pour cette étude, nous nous sommes inspirés des travaux de Bronner à propos du numérique pour élaborer un outil, le filtre des grandeurs, qui sert à décrire et analyser les pratiques relatives aux grandeurs au collège. Plus particulièrement, nous nous sommes intéressés aux interrelations entre les grandeurs, le fonctionnel et le numérique en prenant le cas de la proportionnalité, et au fonctionnement interne des grandeurs en étudiant l'espèce de grandeur aire.La recherche met en évidence que l'introduction des grandeurs en tant que domaine d'étude dans les programmes du collège de 2005 crée chez les professeurs des difficultés dans l'intégration des nouvelles technologies et théories pour un enseignement adéquat des grandeurs. De plus, elle montre une certaine stabilisation de la place et la fonction des grandeurs dans la construction d'autres domaines mathématiques, mais met en évidence des difficultés au niveau des interrelations entre ces domaines. / This research aims at studying the place and role of magnitudes in the development of different mathematics fields and in their interrelations at school. Our perspective is that of the Anthropological Theory of the Didactic developed by Yves Chevallard. An epistemological analysis of the mathematical knowledge related to magnitudes allowed us to examine certain institutional choices and their impact on teaching. This work is complemented by an ecological and praxeological study of the curricula, school textbooks and corporate documents to characterize the institutions' relations to magnitudes. A clinical type methodology was used to analyze the knowledge concerning magnitudes taught in grade 6 and 7 in France. This study was inspired by Bronner's work about the numeric to develop a tool - a magnitudes filter - which is used to describe and analyze the practices related to magnitudes at school. In particular, this research focused on the interrelations between the magnitudes, the functional and the numeric in the case of proportionality and on the internal functioning of magnitudes in the case of the area magnitude.As a result, this research shows that the introduction of magnitudes as a study domain in school programs of 2005 creates difficulties among professors in integrating new technologies and theories for an adequate teaching of magnitudes. Moreover, it shows a certain stabilization of the place and role of magnitudes in the development of different mathematics fields, but difficulties concerning the interrelations between these areas.

Made available in DSpace on 2016-04-27T16:59:06Z (GMT). No. of bitstreams: 1 Jacinto Ordem.pdf: 1754953 bytes, checksum: 53e18c5b0f3b1f7cb5bdd2f67fb1fc6c (MD5) Previous issue date: 2010-05-27 / Fundação Ford / This study aimed to understand the approach of proof and proving of properties of triangles present in textbooks for the 6th to the 8th series of Mozambique. The properties, the object of study, are the sum of internal angles, the relationship between the external and the internal angle non-adjacent and the relationship of congruence between triangles. Thus, the study sought to answer the following question: How do the texbtbook in use in schools (Mozambique) present the organization of the study about triangles and how they tech this object with a focus on proof and proving. The study was based on the work of Nicolas Balacheff about the processes of validation tests, Raymond Duval works about records of semiotic representations and Yves Chevallard works about the praxeological organization. The research has methodological procedure as the collection and analysis of bibliographic data. The study results showed that in the textbooks examined predominantly pragmatic proof. The authors emphasize the records figural and discursive in natural and symbolic language in these books and they have clear tasks with the technological-theoretical discourse available. But, the study results show that conversions are not adequately explored in the study of triangles and the reconfiguration is not fully exploited to produce arguments that could support intellectual proof / Este estudo teve por objetivo compreender a abordagem da prova e da demonstração de propriedades de triângulos presentes em livros didáticos da 6ª a 8ª séries de Moçambique. As propriedades, objeto de estudo, são a soma dos ângulos internos, a relação entre um ângulo externo e os internos não adjacentes, bem como a relação de congruência entre triângulos. Desse modo, o estudo pretendeu responder à seguinte questão: Como os livros didáticos em uso nas escolas (de Moçambique) apresentam a organização matemática e didática do objeto triângulo, com enfoque na prova e demonstração. O estudo fundamentouse nos trabalhos de Nicolas Balacheff sobre os processos de validação de provas, Raymond Duval sobre os registros de representações semióticas e Yves Chevallard sobre a organização praxeológica. A pesquisa teve como procedimento metodológico a coleta e a análise de dados bibliográficos. Os resultados do estudo mostraram que nos livros didáticos analisados predominam provas pragmáticas. Os autores privilegiam os registros figurais e discursivos em línguas natural e simbólica e apresentam em tais livros tarefas claras com o discurso tecnológico-teórico disponível. Mas, os resultados do estudo mostraram que as conversões não são devidamente exploradas no estudo dos triângulos e a reconfiguração não é aproveitada para produzir argumentos que poderiam fundamentar provas intelectuais

Orientador: Edmundo Antonio Peggion / Resumo: O Instituto Brasileiro de Geografia e Estatística mantêm uma série histórica e coesa dos Censos Demográficos desde 1940, apresentando a cada 10 anos um "retrato do Brasil". A partir dos anos 1980 as comunidades científicas e confessionais tem se interessado pelos resultados deste levantamento quanto ao quesito religião. O IBGE apresenta uma única categoria sobre a religiosidade do recenseado em seu Censo Demográfico, “Qual sua Religião ou culto?”, caso responda-se de forma negativa o respondente será categorizado como Sem Religião. Percebe-se que dentro desta categoria não estão só ateus e agnósticos, mas também pessoas que vivenciam sua vida religiosa de alguma outra forma. Esta pesquisa de mestrado busca encontrar na série histórica da cidade de Araraquara - SP a produção do número destas pessoas. Os desafios teóricos e metodológicos foram e são como lidar com esta população específica tanto do ponto de vista estatístico quanto do ponto de vista empírico. Como preencher o dado númerico de sentido. Para tanto, reconstruímos a mobilidade religiosa da cidade de referência fazendo uma crítica da construção deste número e como narrar esta categoria ao longo do tempo.

Since the 1980s, the scientific and faith-based communities have taken an interest in the results of this survey regarding the religion department. The IBGE presents a single category on the religiosity of the registered in its Demographic Census, "Which is your religion or cult?", if responds in a negative way the respondent will be categorized as Without Religion. One can see that within this category there are not only atheists and agnostics, but also people who experience their religious life in some other way. This master's research seeks to find in the historical series of the city of Araraquara - SP the production of the number of these people. The theoretical and methodological challenges were and are how to deal with this specific population both from a statistical and an empirical point of view. How to fill in the numeric data of sense. To do so, we reconstruct the religious mobility of the city of reference by criticizing the construction of this number and how to narrate this category over time. We sought to build a rapprochement with a place that would congregate these people Without Religion. / Mestre

Orkestrering för ett matematiskt lärande : Praxeologier i matematikundervisning / Orchestration for mathematical learning : Praxeologies in mathematics education

Herbut, Sebastian, Sandström, Nicklas January 2023 (has links)
I den här studien åskådliggörs tre skilda perspektiv på hur undervisning kan planeras ochorganiseras i relation till matematikinnehåll, struktur och yttre resurser. Tidigare forskningbelyser hur lärarens arbete kring planering i stor utsträckning kan vara avgörande förelevernas lärande i matematik. Vidare belyser studien vikten av reflektioner och planering föratt medvetet uppmärksamma eleverna på de kritiska momentana inom matematiken.Skolinspektionens (2020) rapport benämner hur allt färre lärare reflekterar kring sin egenundervisning i syfte att utveckla lärandet. Resultaten pekar på ett liknande fenomen närdeltagarna talar om reflektionens roll för undervisningen. Vidare synliggör studienläromedlets roll för både planeringsarbetet, genomförandet av undervisningen samtreflektionen.

Objetos que ensinam em museus: análise do diorama do Museu de Zoologia da USP na perspectiva da praxeologia / Objects that teach in museums: the analysis of the diorama of USP Zoology Museum in the perspective of the praxeology

Bueno, Juliana Pavani de Paula 17 November 2015 (has links)
Mudanças na economia, na sociedade e no mundo do trabalho deram grande destaque à educação não formal ao longo da segunda metade do século XX, gerando maior valorização dos processos de aprendizagem que se preocupam em aproximar a ciência, a tecnologia, a sociedade e o ambiente. Nesse cenário, uma das questões e desafios que se revelam está em torno do como realizar a socialização do conhecimento científico. De acordo com Marandino (2004), a transformação do conhecimento científico, com fins de ensino e divulgação, pode ser analisada no intuito de compreender a produção de novos saberes nesses processos. Nesse sentido, encontramos na Teoria Antropológica do Didático (TAD), proposta por Chevallard (1991), o referencial teórico que permitiu identificar quais saberes são produzidos pelo museu, por meio de suas ações educativas, e que podem ou não ser observados pelo visitante, por meio de uma Organização Praxeológica (OP). Atualmente, vários meios museográficos são usados na preparação de exposições de museus de ciências e, entre eles, destacam-se os dioramas. O entendimento dos dioramas como objetos didáticos, produzidos com a finalidade de ensino e aprendizagem, implica estudá-los numa perspectiva praxeológica, pois permite visualizar a articulação entre a dimensão prática e a teórica do objeto que está sendo analisado. O estudo da praxeologia em museus foi recentemente desenvolvido e busca, entre outros aspectos, analisar como revelar determinados conhecimentos e objetivos em um espaço, de forma inteligível para diferentes tipos de público. O objetivo deste trabalho foi verificar como os museus ensinam por meio de exposições, em especial, pelo diorama \"Floresta Amazônica\", presente na exposição do Museu de Zoologia da USP. A metodologia desenvolvida incluiu a elaboração de um quadro praxeológico a partir dos dados obtidos por três instrumentos de coleta: documentos sobre a exposição e sobre o diorama; entrevistas com os designers e/ou os responsáveis pela exposição; e por meio da descrição e da observação do diorama. A análise qualitativa dos dados permitiu identificar a teoria e a tecnologia do diorama no contexto de sua exposição e, também, as tarefas e as técnicas propostas. Os resultados obtidos ajudaram a identificar o potencial educativo do diorama e serviram como proposta para desenvolver processos de produção de exposições em museus de ciências. / Changes in the economy, in the society and in the world of work gave great prominence to non-formal education, during the second half of the twentieth century, generating greater appreciation of learning processes, which are concerned to approach the relationship among science, technology, society and environment. In this scenario, one of the issues and challenges that unfold, is around how to perform the socialization of scientific knowledge. According to Marandino (2004), the transformation of scientific knowledge for purposes of education and dissemination, can be analyzed in order to understand the production of new knowledge in these processes. Accordingly, we find in Anthropological Theory of the Didactic (TAD), proposed by Chevallard (1991), the theoretical framework that will identify which knowledge is produced by the museum, through its educational activities, and that they can or can not be observed by the visitor, through a praxeological Organization (OP). Nowadays, several museographic means are used in the preparation of exhibitions, in science museum, and among these, we highlight the dioramas. The understanding of dioramas as didactic objects produced for the purpose of teaching and learning, involves studying them in a praxeological perspective, because it allows to visualize the relationship between the theoretical and the practical dimension of the object being analyzed. The study of praxeology in Museums has been recently developed and it seeks, among other things, to examine how to expose certain knowledge and objectives in a space, in intelligible form for different types of public.The objective of this work was to investigate how museums teach through exhibitions, especially the diorama \"Amazon Forest\" present at the exhibition of the USP Zoology Museum. The methodology included the development of a praxeological framework from the data obtained by three collection tools: documents about the exhibitions and the diorama; interviews with the designers and/or responsible for the exhibition; description and observation of the diorama.The qualitative analysis identified the theory and technology in the context of his exhibition and also the tasks and technical proposed for the diorama.The results allowed us to identify the educational potential of the diorama and they served as a proposal to the development of processes for producing exhibitions in science museums.

Análise combinatória: organizações matemáticas e didáticas nos livros escolares brasileiros no período entre 1895-2009

Pinheiro, Carlos Alberto de Miranda 17 March 2015 (has links)
Made available in DSpace on 2016-04-27T16:57:36Z (GMT). No. of bitstreams: 1 Carlos Alberto de Miranda Pinheiro.pdf: 3726604 bytes, checksum: 7f0acb671f10ca6a3f9af822c2232603 (MD5) Previous issue date: 2015-03-17 / This paper presents the development of a research, which proposed to investigate the knowledge of Combinatorial Analysis studied in the Brazilian schools during 1895 and 2009. This research articulates inside a project called Educação Estatística e Educação Financeira na Escola Básica (Statistical Education and Financial Education in Basic School), linked to the research group PEA-MAT. We analysed some didactic aspects and mathematicians present in seven textbooks used in Brazilian schools during that time, we also had a bibliographical and documental study in presuppositions of content analysis. We wanted to answer the following investigation question:what characteristics of knowledge insertion of Combinatorial Analysis are identified in textbooks during 1895 and 2009? The first phase of content analysis consisted in collecting and studying texts that would inform us what textbooks presented the knowledge of Combinatorial Analysis and some aspects of historical moments of these books, since the foundation of the Pedro II School. With this, we identified that the program of 1895 was the one with more insertion of textbooks and new school contents, before the main educational reforms occurred in the first decades of the XX century. We also tried to identify on the website of the Programa Nacional do Livro Didático (PNLD-Ensino Médio) (National Program of Textbooks-High School) the Mathematic book more used in Belémdo Pará schools, in the first phase of the program, 2004-2009. The second phase of content analysis was the material exploration. In this phase we analysed based on the Anthropological Theory of Didactic, specifically about the praxeological organizations not only mathematical but also didactic, together with the notion of didactic models proposed by Josep Gáscon. Among the results observed, we highlight that while in the first books the focus was only on presentation of formulas deduction, some years later, the task of calculating the values from those formulas was introduced, modifying the approach from theoretical to technical or classic. We can also observe the change in the techniques to calculate the Arrange and the Permutation in the book produced based on the Movement of Modern Mathematics and in a more recent book, approved by the PNLD-Ensino Médio. The tasks and the techniques related to the calculation of numbers of simple combinations will not undergo transformations as time goes by. That is, the praxeological organization identified in the block task/technique/technology/theory changed from a theoretical to a technical approach during the whole period studied / Este trabalho apresenta o desenvolvimento de uma pesquisa que se propôs a investigar os saberes da Análise Combinatória estudada nas escolas brasileiras, no período entre 1895 e 2009. Esta pesquisa articula-se no interior do projeto Educação Estatística e Educação Financeira na Escola Básica , vinculado ao grupo de pesquisa PEA-MAT. Analisamos alguns aspectos didáticos e matemáticos presentes em sete livros didáticos que circularam nas escolas brasileiras, no período em questão, realizando um estudo bibliográfico e documental fundamentado em pressupostos da análise de conteúdo. Buscamos responder à seguinte questão de investigação: que características de inserção dos saberes da Análise Combinatória nos livros didáticos podem ser identificadas no período 1895-2009? A primeira fase da análise de conteúdo consistiu em reunir e estudar textos que nos informassem quais livros escolares apresentavam os saberes da Análise Combinatória e alguns aspectos do momento histórico desses livros, desde a fundação do Colégio Pedro II. Com isso, identificamos que o programa de 1895 foi o que teve a maior inserção de livros didáticos e de novos conteúdos escolares, antes das principais reformas educacionais ocorridas nas primeiras décadas do século XX. Também procuramos identificar no site do Programa Nacional do Livro Didático (PNLD-Ensino Médio) o livro de Matemática mais utilizado nas escolas de Belém do Pará, na primeira fase de implantação desse programa, 2004-2009. A segunda fase da análise de conteúdo foi a exploração do material. Nesta fase foi realizada uma análise à luz da Teoria Antropológica do Didático, especificamente sobre as organizações praxeológica tanto matemáticas como didáticas, juntamente com a noção de modelos didáticos, proposta por JosepGáscon. Entre os resultados observados, destacamos que, enquanto nos primeiros livros o enfoque era apenas a apresentação da dedução das fórmulas, ao longo do tempo foi inserida a tarefa de calcular os valores a partir dessas fórmulas, passando, assim, de uma abordagem puramente teoricista para uma abordagem tecnicista ou clássica. Observa-se, também, uma mudança nas técnicas para calcular o Arranjo e a Permutação no livro produzido à luz das ideias do Movimento de Matemática Moderna e no livro mais recente, aprovado no PNLD-Ensino Médio. As tarefas e as técnicas, relativas ao cálculo do número de combinações simples, não sofreram transformações, ao longo do tempo. Ou seja, a organização praxeológica identificada no bloco tarefa/técnica/tecnologia/teoria passou de uma abordagem teoricista para uma abordagem tecnicista ou clássica ao longo de todo o período estudado
