The question of this work was: how games and manipulative materials are used in mathematics education for deaf children? To answer this and other questions, interviews were conducted with teachers of three deaf education centers. The general objective was to analyze the games and manipulative materials used by math teachers in deaf education in schools of Cascavel and Foz do Iguaçu. To choose the schools the following criteria were used: only schools for the deaf, bilingual schools, schools where teachers use games to teach mathematics to deaf students. First, is presented a historical summary about deaf education and the main approaches: oralism, total communication and bilingualism. The oralist approach defends the teaching of oral speech for the deaf. Total communication defends all types of communication during the educational process of the deaf. Total communication is not recommended, because isn't systematized. In this work the bilingualism is defended. Bilingualism starts with the teaching of the sign language as the first language and of the written form of the portuguese as second language. In order to teach deaf students is necessary to consider that they learn different than listeners. Deaf people need a sensorial education. To address the games and manipulative materials in mathematics education, the theories of Piaget and Vygotsky are adopted. Piaget is the starting point to understand the play and its role in the construction of the number. Vygotsky's theory helps to understand the importance of sign language for a meaningful teaching to the deaf child. We conclude that the games are indispensable in the lives of deaf and hearing children, as they influence the development and the construction of the number. / Esta dissertação aborda os materiais manipuláveis e jogos usados na educação de matemática de crianças surdas. A investigação partiu da seguinte questão: como os jogos e materiais manipuláveis são utilizados no ensino de matemática de crianças surdas? Para responder esta e outras questões, foram realizadas entrevistas com as professoras de três centros de educação de surdos. O objetivo geral foi analisar os jogos e materiais manipuláveis utilizados pelas professoras de matemática em escolas de educação de surdos de Cascavel e Foz do Iguaçu. Para a escolha das escolas foram utilizados os seguintes critérios: escolas somente para surdos, escolas bilíngues, escolas com professores que usam jogos no ensino de matemática para alunos surdos. Primeiramente, o trabalho trata do histórico da educação de surdos e apresenta as três principais abordagens: oralismo, comunicação total e bilinguismo. O oralismo defende que a fala seja ensinada para o surdo. A comunicação total aceita todos os tipos de comunicação. Não é considerada uma abordagem recomendável, por não ser sintetizada. O bilinguismo, aqui defendido, parte do ensino da língua de sinais como primeira língua e o ensino da língua portuguesa como segunda língua na modalidade escrita. Tal abordagem é considerada mais adequada à educação de surdos. É necessário considerar que os surdos aprendem de modo diferente dos ouvintes. Os surdos precisam de uma educação visual. Para abordar os jogos e materiais manipuláveis no ensino de matemática, são adotadas as teorias de Piaget e Vygotsky. Piaget é o ponto de partida para entender o brincar e a construção do número pela criança. A teoria de Vygotsky ajuda a compreender a importância da língua de sinais para que o ensino seja significativo para a criança surda. Conclui-se que os jogos são indispensáveis na vida das crianças surdas e ouvintes, pois influenciam no desenvolvimento e na construção do número.

Vigotski. Compõem o texto um estudo dos argumentos de Vigotski no diálogo com seus contemporâneos, mais particularmente, com A. Adler; uma análise dos modos de apropriação do conceito por autores na atualidade; uma reflexão analítica das ideias de autores que marcaram a história da educação da criança com deficiência no Brasil. Com base nessas discussões, enfoca-se o caso de um aluno com deficiência múltipla inserido no ensino fundamental de uma escola pública brasileira, buscando-se analisar: 1- As (im)possibilidades de desenvolvimento humano produzidas nas relações de ensino; 2- O núcleo conceitual e teórico que ancora o conceito de compensação. 3- As implicações e repercussões do conceito que possam contribuir para políticas e práticas de educação inclusiva. Considera-se a relevância de colocar em discussão a impertinência do termo compensação na possível intersecção com a noção de constituição humana / Abstract: The objective of this work is to discuss the concept of compensation from the formulations of Lev S. Vygotsky. The text comprises: a study of the arguments of Vygotsky in dialogue with his contemporaries, more particularly with A. Adler; an analysis of the modes of appropriation of the concept by authors nowadays; an analytical reflection of the ideas of authors who have marked the history of the education of children with disabilities in Brazil. Based on these discussions, it focuses on the case of a student with multiple disabilities who entered primary education in a Brazilian public school, and seeks to analyze: 1 - The (im)possibilities of human development generated in teaching relationships; 2 - The conceptual and theoretical core that anchors the concept of compensation; 3 - The implications and impact of the concept that can contribute to inclusive education policy and practice. This work also considers the relevance of putting into discussion the irrelevance of the term compensation in possible intersection with the notion of human constitution / Doutorado / Psicologia Educacional / Doutora em Educação

Adota-se como premissa desta pesquisa aplicada obter indícios do desenvolvimento de habilidades de raciocínio lógico-matemático pela aprendizagem em programação em blocos, mediada pela utilização de tecnologias digitais da informação e comunicação. Para tal, realizaram-se capacitações online, com pessoas de diferentes faixas etárias e escolaridade, via ambiente virtual de aprendizagem (AVA) Moodle, configuradas de modo a fomentar as interações entre os participantes utilizando como base as teorias socioculturais. Outrossim, introduziram-se os princípios da computação e pensamento computacional com foco nas ferramentas Code.org e Scratch, consistindo em um ambiente de educação online com múltiplos desafios divididos em etapas e graus de dificuldade. Os resultados indicaram que a proposta teve o principal resultado esperado (melhoria no raciocínio lógico-matemático) fora alcançado. Além disso, houve a percepção positiva de melhora na resolução de problemas do cotidiano, indicando a proposta como promissora para o ensino-aprendizagem do pensamento computacional e da programação em blocos. / It is adopted as a premise of this applied research to get indications of the development of logical-mathematical reasoning abilities by the learning in programming in blocks, mediated by the use of digital technologies of information and communication. To this end, online trainings were carried out, with people of different age groups and schooling, via virtual learning environment (AVA) Moodle, configured in order to foster interactions among participants based on sociocultural theories. In addition, the principles of computation and computational thinking focused on the Code.org and Scratch tools were introduced, consisting of an online education environment with multiple challenges divided into stages and degrees of difficulty. The results indicated that the proposal had the main expected result (improvement in logical-mathematical reasoning). In addition, there was a positive perception of improvement in the resolution of everyday problems, indicating the proposal as promising for the teaching-learning of computational thinking and block programming.

Metallic fuels have an important role to play in "fast breeder" Gen-IV type nuclear reactors, and U-Pu-Zr is one of the prototypical systems. Because of the variability in fuel chemistry during burn-up, it is important to understand the effect of minor actinides and fission products on phase stability. Within this framework, we present a study on phase equilibria in the binary Np-Zr alloy system on which little work has been published. To resolve the contradictory reports on the ordering/ clustering trends of the bcc phase, a thermodynamic study is performed using the CALPHAD method. The calculated Np-Zr phase diagram is consistent with two sets of data: formation enthalpies of the bcc phase that are calculated with ab initio KKR-ASA-CPA electronic-structure method and lattice stabilities of solution phases obtained from first-principles technique. Another important feature in the Np-Zr alloy system is the non-stoichiometric delta-NpZr2 phase that forms in a hexagonal C32 structure similar to the delta-phase in the U-Zr system and the w-phase in pure Zr. An increase in the homogeneity range of the delta-phase when going from Pu to Np and to U is attributed to a lowering of its heat of formation that is caused by an increase in d-band occupation. Two different possibilities for the stability of the delta- and w- phases have been proposed in the present work. Additionally, calculated changes in enthalpy versus temperature are plotted for two alloy compositions of the Np-Zr system to guide future experimental work in resolving important issues in this system. Finally, an ab initio study, implemented with the L(S)DA U formalism, is performed for pure Np that reveals a transition from a non-magnetic to a magnetic state at a critical U parameter.

ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NV / The flight test mission services need higher data rates due to increased system complexity and the need for more accurate, higher rate, and better data acquisition. The existing L or S band frequency spectrum allocation was a limiting factor to meet this increased data rate requirement. The World Radio-communication Conference (WRC 2007) attributed new additional frequency spectrum allocations in the C band for Aeronautical Mobile Telemetry (AMT). The international flight test community has taken this opportunity to immediately take advantage of the new C-band range 5091-5250MHz. This paper presents the multi-band feed product designed by the RF & Antenna Laboratory of ZODIAC DATA SYSTEMS company. This feed is foreseen to be used in prime focus configuration on any diameter parabola dish providing telemetry and tracking channels in three L, S, and C bands. Here, are described the concept and the technology achieved taking into consideration the performance and industrial constraints. Moreover, this contribution focuses on the electromagnetic simulations of radiating elements, the feed network and RF system integration. This paper is structured as follows: firstly, the objectives and the motivation for developing a prime focus feed which works in L, S, C bands are presented. In particular, the market constraints and approach to find the best solution satisfying the feed RF requirements, and mechanical constraints, such as weight, size and cost, are discussed. The second section describes the 5 step development cycle: principle and technology, design of the telemetry channels and tracking function, cohabitation of the different radiating elements, and problems of the channels isolations. The third section discusses the performance achieved using electromagnetic simulations. The fourth section talks about the integration of RF system feed. The paper concludes by discussing future work using the same concept that is applied to other telecommunication or telemetry frequency bands.

Il y a presque trente ans, un des probl??mes les plus difficiles de la physique moderne voyait le jour: la supraconductivit?? ?? haute temp??rature critique dans les cuprates. Depuis, l'hypoth??se nomm??e mod??le Hubbard est rapidement devenu un des candidats les plus prometteurs ?? en d??tenir la solution. Dans ce contexte, ce m??moire pr??sente des travaux de calculs num??riques sur les phases de la mati??re pr??dites par le mod??le de Hubbard. Le projet poursuit notamment deux objectifs. En premier lieu, on consid??re un couplage interplan dans le mod??le, ce qui le rend plus r??aliste que sa version 2D habituelle. Et en deuxi??me lieu, on laisse les phases antiferromagn??tique et supraconductrice coexister avec en plus une autre phase supraconductrice de type pi-triplet. Plus de d??tails sur le contexte et ces deux objectifs sont pr??sent??s au chapitre 1 et le mod??le de Hubbard est d??taill?? au chapitre 2. Pour obtenir des solutions num??riques au mod??le, les m??thodes utilis??es sont la th??orie de champ moyen dynamique sur amas (CDMFT) et l'approximation de l'amas variationnel (VCA). Ces m??thodes ainsi que le formalisme n??cessaire pour les aborder sont pr??sent??s au chapitre trois. Notons qu'on utilise ces m??thodes pour amas avec des m??thodes de diagonalisation exacte qui ne feront pas partie de la discussion. Enfin, le dernier chapitre pr??sente tous les r??sultats obtenus avec ce projet, qui m??nent ?? deux conclusions principales. Premi??rement, le couplage tridimensionnel tel qu'ajout?? n'a pas fait ressortir de tendance nette dans les r??sultats. Cela indique une de deux choses: soit les effets interplans sont n??gligeables dans le mod??le de Hubbard, soit il faudra les inclure d'une fa??on plus compl??te dans le futur. Deuxi??mement, on observe que la phase pi-triplet appara??t lorsqu'il y a coexistence entre l'antiferromagn??tisme et la supraconductivit?? dans le mod??le mais que ces deux derni??res phases se nuisent fortement l'une ?? l'autre, confirmant qu'il y a comp??tition de phases.

Este trabalho é fruto de uma pesquisa de iniciação científica, que analisou as concepções de escola em autores contemporâneos sob a perspectiva da Teoria da Atividade, comparando-as com as ideias pedagógicas contidas nos trabalhos de Vigotski, Leontiev e Luria. No decorrer dessa pesquisa constatou-se que muitas dessas concepções sobre a escola eram perpassadas pela questão da cultura. Portanto, com o objetivo de um estudo aprofundado, selecionamos autores como Bruner e Vigotski porque ambos desenvolveram uma concepção de cultura que traz várias implicações para a Educação Escolar na atualidade. Para analisar a cultura nas obras de Bruner e Vigotski, procedemos inicialmente a uma primeira leitura exploratória por meio da qual apreendemos de suas obras núcleos teóricos conceituais, sejam eles: universo simbólico, narrativa e comunidade cultural, para o primeiro autor; e natureza social do psiquismo, signos ou instrumentos culturais e função psíquica superior, para o segundo autor. Feito isso, realizamos uma análise comparativa dessa concepção e constatamos que Bruner transita em um veio fenomenológico hermenêutico, afirmando premissas da pós-modernidade e do multiculturalismo; enquanto Vigotski em uma vertente materialista histórico-dialética sustenta a ontologia do ser ligado à sua historicidade e às relações sociais. No que tange a análise dialética singular-particular-universal, concluímos que a concepção de cultura entre os dois autores se distancia. Para Bruner essa concepção é focada na particularidade aparente, já Vigotski, entende que a prática humana, na qual se inclui a produção da cultura,... / The objective of this master’s research was to analyze the concept of culture in selected works of the North American psychologist, Jerome Bruner, and of the Soviet psychologist, Lev Semenovich Vigotski, and the implications for school education. This work is the result of scientific initiation research and is an analysis of the concept of school in the writings of contemporary authors, from the perspective of the activity theory, comparing these concepts with the pedagogical ideas in the work of Vigotski, Leontiev and Luria. During the research, it was found that many of these concepts of school are imbued with the issue of culture. In order to carry out an in-depth study, we selected authors like Bruner and Vigotski, as both developed a concept of culture that has various implications for school education today. To analyze the concept of culture in the work of Bruner and Vigotski, we began with an initial exploratory reading through which we grasped the existence in their work of a theoreticalconceptual unity, as follows: symbolic universe, cultural narrative and community in the case of the first author, and the social nature of psychism, signs or cultural instruments, and superior psychic function, in the case of the second author. That done, we carried out a comparative analysis of this conception and found that Bruner follows a hermeneutic phenomenological vein, affirming the premises of postmodernism and multiculturalism, while Vigotski, from a materialistic, historical-dialectic angle, supports the ontology of being linked to his historicity and social relations. With regard to the singular-particular-universal dialectic analysis, we concluded that the conception of culture is distant when comparing these two authors. For Bruner, the conception is focused on particularity, while for Vigotski, it is human practice, including the production of culture, which always contains the ...

Repleto de significados foi incorporado na linguagem, na arte, na religião e na cultura em geral. Seus estudiosos se estendem pela Filosofia (WITTGEINSTEIN, 1958; HUIZINGA, 1991; SCHILLER, 1995), História (ARIÈS, 1978; CAILLOIS, 1958), Teoria da Comunicação (POSTMAN, 1994), Antropologia (GEERTZ, 1989; MALINOWSKI, 1978) e inevitavelmente pela Educação e Psicologia. Embora nos reportemos com freqüência as demais ciências, nosso trabalho se insere numa tradição psicológica. Buscamos nas teorias do psicólogo russo Lev Vygotsky (1896-1934) e do psicanalista inglês Donald Winnicott (1896-1971) uma alternativa para a compreensão do jogo infantil e seu significado na produção da subjetividade. Partimos da apresentação dos autores e suas respectivas biografias intelectuais, detalhando suas concepções de indivíduo, sujeito e meio (social, ambiental e cultural), para em seguida explorarmos conceitualmente zonas de sentido entre suas teorias. Na direção metodológica encaminhamos a discussão a partir da Epistemologia Qualitativa desenvolvida por Gonzalez Rey, criando zonas de sentido entre as concepções de ambiente e jogo infantil. Diante da morte precoce de Vygotsky e a consequente interrupção das suas pesquisas sobre o jogo, buscamos nas teorias dos seus alunos e colaboradores - principalmente Leontiev e Elkonin - os princípios ontogenéticos do jogo infantil complementares à explanação vigotskiana. Defendemos que uma teoria do jogo infantil deve buscar origens nas relações sociais mais primitivas do indivíduo, bem como no uso mais precoce que este faz dos objetos. Tais relações foram amplamente detalhadas por Winnicott na sua teoria dos fenômenos e objetos transicionais e acreditamos que podem ser relevantes para a compreensão do jogo protagonizado, tal qual desenvolvido por Elkonin e Vygotsky / The game is set in one of the oldest human activities. It was full of meanings embedded in language, art, religion, and culture in general. His scholars extend the Philosophy (WITTGEINSTEIN, 1958; HUIZINGA, 1991; SCHILLER, 1995), History (ARIÈS, 1978; CAILLOIS, 1958), Communication Theory (POSTMAN, 1994), Antropology (GEERTZ, 1989; MALINOWSKI, 1978) and inevitably for Education and Psychology. Although we refer frequently to other sciences, our work is part of a psychological tradition. We seek theories of the Russian psychologist Lev Vygotsky (1896-1934) and the English psychoanalyst Donald Winnicott (1896-1971) an alternative to the understanding of children's play and its significance in the production of subjectivity. We start from the presentation of the authors and their intellectual biographies, detailing their conceptions of individual, subject and the environment (social, environmental and cultural), then to conceptually explore areas of meaning between their theories. Following toward a methodological discussion, we discuss the Qualitative Epistemology developed by Gonzalez-Rey, creating zones of meaning between the concepts of environment and children's game. Given the early death of Vygotsky and the consequent disruption of their research into the game, we turn to the theories of his students and collaborators - mostly Leontiev and Elkonin – with the principles ontogenetic children's game, a complementary explanation to Vygotsky’s theory. We argue that a theory of children's play should seek origins in more primitive social relations of the individual as well as the earlier use of objects that he makes. Such relationships have been widely detailed by Winnicott in his theory of phenomena and transitional objects, and we believe may be relevant to understanding the game played in children, as it was developed by Eldkonin and Vygotsky
