Previous issue date: 2010-02-25 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This paper aimed to study the Emancipation category in selected works of Paulo Freire as a subsidy to a proposal for sexual education. The study investigated which contributions on previously selected works could contribute to the construction of an emancipatory sexual education project, and willingness to cooperate with the teachers in their educational practices, so that may result in processing actions of social reality, seeking to be more of citizenship for all. Initially the emancipation category was carefully framed to emphasize and understand their field of action in the construction of an emancipatory education process, recognizing it as well as a fundamental approach to sexual education that is the basis of this research beyond the dialectic s category, in view of historical and dialectical materialism. The meanings of the emancipation category were formed by indicators such as humanization and liberty, which unveiled in Be More Support category. Associated with these indicators were found Utopia and social transformation indicators that unveiled in the radicalization Support category. Awareness and Word complete the basis of indicators, unveiled in the Dialogue Support category. The indicators have been intertwined roots in the deep texts studied in works of Paulo Freire that emerged vigorously supported by its meanings of the Support category when unveiled, and this triad in turn, when interwoven and strengthened, motivated the establishment of the emancipation category and those are fundamental elements to subsidy the intentional sexual education process / O trabalho teve como objetivo o Estudo da Categoria Emancipação em Obras de Paulo Freire como subsídio a uma proposta de Educação Sexual. Investigou quais as obras previamente selecionadas do referido autor que podem contribuir na perspectiva da construção de um projeto de educação sexual emancipatória, e com a intenção de colaborar com os professores e professoras em suas práticas educacionais para que as mesmas possam resultar em ações transformadoras da realidade social, na busca de cidadania para todos. Inicialmente a categoria emancipação foi minuciosamente esquadrinhada para entender e enfatizar o seu campo de ação na construção de um processo de educação emancipatório, reconhecendo-a também como parte fundamental da abordagem de educação sexual que é base da presente pesquisa, além da categoria da dialética, na perspectiva do materialismo histórico-dialético. Os significados da categoria emancipação foram se constituindo por meio dos indicadores como a Humanização, a Liberdade, que se desvelaram na Categoria de Suporte Ser Mais. Associados a esses indicadores foram encontrados os indicadores Utopia e Transformação Social que se desvelaram na Categoria de Suporte Radicalização. E completando a base de indicadores a Conscientização e a Palavra que se revelaram na Categoria de Suporte Diálogo. Os indicadores foram as raízes entremeadas nas profundezas dos textos estudados, em obras de Paulo Freire que, ao serem desvelados, emergiram e sustentaram vigorosamente com suas significações as Categorias de Suporte e esta tríade, por sua vez, ao se entrelaçar fundamentou a constituição da categoria emancipação e são elementos fundamentais para subsidiar processos intencionais de educação sexual

Avaliação da política pública "Programa Mais Educação" em escolas de ensino fundamental da rede estadual de ensino do Rio Grande do Sul / Evaluation of the public policy “Programa Mais Educação” (More Education Program) in elementary public schools, in Rio Grande do Sul state : the effects on the quality of education and on elementary school fundingMosna, Rosa Maria Pinheiro January 2014 (has links)
Esta tese se insere no campo da avaliação de política pública e com esse escopo faz a avaliação da implementação da política do governo federal denominada “Programa Mais Educação” que se propõe a ser um indutor da ampliação da jornada escolar na perspectiva da educação integral. Trata-se de uma pesquisa de caráter qualitativo que teve como objetivo geral avaliar processos de implementação e impactos do Programa na qualidade da educação e no financiamento do ensino fundamental em escolas da rede estadual de ensino do Rio Grande do Sul. Nos aspectos teóricos, o estudo apresenta um breve histórico da política pública enquanto campo de conhecimento e aspectos legais e conceituais de política pública e de avaliação de política. Como referencial metodológico foi utilizado o modelo analítico do ciclo de política de Stephen Ball e Richard Bowe, por ser uma abordagem que propicia a investigação das políticas como um processo contínuo, bem como pela sua preocupação com os efeitos das políticas. Quanto ao viés avaliativo, foram utilizadas, em especial, as orientações metodológicas de textos de Sonia Draibe e de Marta Arretche, em análises que contemplaram quatro dimensões e suas inter-relações: gestão; relação escola/comunidade; cognitiva/pedagógica; financeira. Como o Programa teve seu início em 2008, nas regiões metropolitanas, esse foi o critério de seleção das escolas para a realização da pesquisa empírica. Foram 49 escolas estaduais contempladas em 2008, localizadas nos municípios de Porto Alegre, Canoas, Gravataí e Viamão. Dessas 49 escolas foram selecionadas onze escolas como amostra para estudo mais aprofundado. No desenvolvimento da tese foi realizado um resgate sucinto das diferentes matrizes filosóficas, ideológicas e políticas do conceito de educação integral, especialmente nas vertentes libertária e liberal, que deram suporte à maioria das experiências de tempo integral que também são apresentadas. Também são caracterizados o Programa Mais Educação – seus objetivos, finalidades, marco teórico – e a política de financiamento da educação, cuja ênfase foi a insuficiência de recursos para cobrir as demandas educativas contemporâneas num contexto de garantia de direitos e o financiamento do Programa na sua relação com os demais recursos recebidos pelas escolas. Além do crescimento expressivo e acelerado do Programa, os achados do estudo indicam um alto grau de satisfação dos beneficiários e dos implementadores, que permite dizer que o Programa tem efetividade social e, de certa maneira, também, tem efetividade institucional, embora, para atingir os objetivos, num grau maior, precise de ajustes, pois ainda não ocorreram as mudanças curriculares que o Programa propõe. A implementação não vem seguindo as orientações dos documentos oficiais, mas alguns documentos apresentam falta de clareza. Os desencontros de finalidades e objetivos identificados se devem à ausência um currículo integral e integrado; à resistência dos docentes em relação aos oficineiros; ao viés reducionista atribuído ao Programa; à falta de regularidade do oferecimento das oficinas; à infrequência e à ausência de acompanhamento sistemático pela mantenedora e de proposta de formação continuada na perspectiva da educação integral para as escolas. / This thesis is in the field of public policies evaluation and, based on that, it evaluates the implementation of the federal government program called “More Education Program” (Programa Mais Educação), which intends to lead to an extension of the school day, on the integral education perspective. It is a qualitative research which has had, as its general goal, to evaluate the program implementation processes and its impact on the quality of education and on the funding of Elementary School, in public schools in Rio Grande do Sul. As for theoretical aspects, the study presents a brief background of the public policy, as a knowledge area and legal and conceptual issues of public policy and policy evaluation. The methodological reference was Stephen Ball and Richard Bowe´s Policy Cycle analytical model. The choice is justified for it is an approach that allows the investigation of policies as a continuous process, as well as its concerns about policies effects. Regarding the evaluative perspective, methodological orientations texts by Sonia Draibe and Marta Arretche have been used in analysis which covered four dimensions and their inter-relations: management; school/community relations; cognitive/pedagogical; financial. Once the Program started in 2008, in the metropolitan regions, those were the criteria for selecting the schools for the empirical research. Forty nine state schools in Porto Alegre, Canoas and Gravataí were accessed. Eleven, out of the forty nine schools, were selected as a sample for deeper studies. During the thesis development there was a brief recovery of the different philosophical, ideological and political matrices of integral education concept, especially in the libertarian and liberal aspects, which supported most of full time experiences, also presented. The Programa Mais Educação – its objectives, purposes, theoretical background is described, as well as the education funding policy, whose emphasis was the resources constraint to afford the contemporary educational demands in a way in which rights are guaranteed, and the Program funding towards other resources received by the schools. Besides the Program´s meaningful and fast growth, findings show a high degree of satisfaction among beneficiaries and implementers. This demonstrates the Program has social effectiveness and, in a way, institutional effectiveness, although, in order to achieve the goals, in a higher degree, it needs some adjustments, once the curricular changes proposed by the Program haven´t happened, yet. The implementation hasn´t been following official documents orientations but some of the documents are not clear enough. The discrepancy between the purposes and the identified goals are due to the lack of a full and integrated curriculum; the educational staff resistance to the workshops instructors; the reductionist characteristic attributed to the Program; the lack of regularity in the workshop offers; the infrequency and lack of systematic follow-up by the government and a proposal of continued education on schools integral education perspective.

Previous issue date: 2015-09-25 / FACEPE / O presente trabalho insere-se nos debates nacionais sobre a atual política de educação (em tempo) integral, mais especificamente, o Programa Mais Educação implementado desde 2007 pelo Governo de Luiz Inácio Lula da Silva. Tendo por objetivo identificar e delimitar as concepções de educação integral e juventude a partir da análise crítica do discurso oficial e dos discursos de seus agentes envolvidos, a presente pesquisa constituiu sua revisão bibliográfica direcionada à composição das categorias teóricas: Política Pública, Juventude e Educação Integral, as quais têm sido trabalhadas por autores vinculados a uma perspectiva histórico-crítica. A metodologia se amparou numa abordagem qualitativa integrada ao método de Análise Crítica do Discurso (FAIRCLOUGH, 2001), e a coleta de dados envolveu entrevistas semiestruturadas com os agentes executores da educação integral, pertencentes à rede pública de ensino do município do Ipojuca (PE), e jovens nela inseridos. Além das entrevistas, os trabalhos de campo envolveram o levantamento de dados por meio do uso da técnica de Grupo Focal junto a um grupo de seis jovens, bem como o exame de documentos coletados na Secretaria de Educação municipal e no Ministério da Educação. A análise dos dados veio indicando que o Programa Mais Educação faz parte de um conjunto de programas que concebe a política de juventude como políticas sociais setoriais dirigidas a determinadas realidades e “tipos” de jovens considerados em situação de risco e vulnerabilidade social. O discurso que toma a juventude como um conjunto social repleto de perfis e traços juvenis diversificados não se evidenciou como discurso hegemônico presente nos contextos de produção, distribuição e consumo dessa política. As contradições encontradas no discurso sobre a concepção de juventude expressou uma tentativa de equilibrar o jovem na condição de sujeito portador de problemas, sendo vulnerável sócio-biologicamente, com outro discurso que convida os professores a compreenderem este grupo social como agentes de sua própria história, isto é, não podendo mais ser considerado como um grupo etário homogêneo. Do mesmo modo, a concepção de educação integral presente nele carregou contradições quando veio ressignificando o escolanovismo liberal dentro do contexto das políticas neoliberais refletidas nos processos de ampliação das funções da escola, nas parcerias público-privadas, na inclusão de territórios educativos para além do espaço escolar, dentre outros. Os jovens envolvidos expressaram as dificuldades e os benefícios do PME levando-nos a indicar uma reorientação dessa política com fomento de ações na direção de um trabalho pedagógico coletivo com os jovens e não apenas para eles. / This work is part of the national debate on the current education policy (in time) full, more specifically, the More Education Program implemented since 2007 by the government of Luiz Inácio Lula da Silva. With the objective to identify and delineate the concepts of comprehensive education and youth from the critical analysis of the official discourse and the discourse of its agents involved, this research constituted a literature review directed the composition of theoretical categories: Public Policy, Youth and Integral Education, which they have been worked by authors linked to a historical and critical perspective. The methodology we relied on an integrated approach to qualitative method of Critical Discourse Analysis (FAIRCLOUGH, 2001), and data collection involved semi-structured interviews with the executing agents of integral education, belonging to public schools in the municipality of Ipojuca (PE) and young inserted in it. Besides the interviews, field work involved data collection through the use of focus group technique with a group of six young as well as the examination of documents collected in the Department of Municipal Education and the Ministry of Education. Data analysis came indicating that the More Education Program is part of a set of programs that conceives youth policy as sectoral social policies directed to certain realities and "types" of young people considered in a situation of risk and social vulnerability. The discourse that takes youth as a social group full of profiles and diversified juvenile traits there was no evidence as hegemonic discourse present in contexts of production, distribution and consumption of that policy. The contradictions within the speech on youth conception expressed an attempt to balance the young provided subjects with problems, being vulnerable socio-biologically with another speech that invites teachers to understand this social group as agents of their own history, that It is, can no longer be considered as a homogeneous age group. Similarly, the concept of comprehensive education this it bore contradictions when it came giving new meaning to the liberal New School in the context of neoliberal policies reflected in the expansion process of school functions, in public-private partnerships, including educational territories beyond space school, among others. The young people involved have expressed the difficulties and benefits of SMEs leading us to indicate a reorientation of the policy with development actions toward a collective pedagogical work with young people and not just for them.

Previous issue date: 2016-08-26 / How can an ethnic identity that has been wiped out, numbed, silenced by colonization process
be identified? In the case of the Chiquitano in the Portal do Encantado-MT, who had positioned
themselves as indigenous people to have the right to remain in their territory, the first
strategy was to trigger the mother tongue which had taken refuge in the memory of their
elders. Thus, the focus of this thesis is to present how, through “memory bilingualism” , this
people could trigger an interactive process of resistance, cultural and political positioning of
identity assertion. An identity that those who remembered (the elders) were able to
reconstruct, given the common unitary point (belonging) of representation and impulsion to
the experience of traditional knowledge. This knowledge, inherited from a common past,
provoked/articulated/triggered a fight in view of the hegemony imposed by the settlers and
their ways of homogenization of knowledge, culture and life. Hence, based on the results of
this study, which entangles decolonial authors and authors who treat the language as
discourse, it is possible to state that the Chiquitano, when triggered the mother tongue which
was stored in their memory, could reach the dwelling for their being and gradually establish a
decolonial process, identifying their identity and their place of belonging. That’s because,
collectively, they acted and promoted the interaction of different generations of people.
Through reflection, they found themselves, creating themselves and their “new” world. By
demanding their own school, they produced science. Giving value to the ancestral knowledge,
they defined the curriculum and pedagogic practices. In this way, they recorded their culture,
which was dormant in the language memory. They produced an authorial and coping
pedagogy. The valorization of their knowledge and their being created the possibilities for
fighting the dominant power. Memory bilingualism was the guiding basis for the training of
teachers and their pedagogic practices, as well as for the assertion of an identity. Everything
together, provided the resurgence of a “being more” (FREIRE, 2014) and led the sociocultural
vitalization of the Chiquitano do Brasil in the Portal de Encantado-MT. / Cómo marcar una identidad étnica apagada, dormida, silenciada a causa del proceso
colonizador? En el caso de los Chiquitano del Portal do Encantado-MT, que necesitaron
posicionarse como indígenas para tener el derecho de permanecer en su territorio, la primera
estrategia fue accionar la lengua materna que estaba refugiada en la memoria de los
ancianos. Es de eso que trata esta tesis, al presentar cómo, a través del “bilingüismo de
memoria” ese pueblo consiguió desarrollar un proceso interactivo de resistencia,
posicionamiento cultural y político de afirmación de la identidad. Esta, por su vez, se dio a
través de los ancianos que recordaban la lengua dado el punto de unidad (pertenencia) común
de representación y de impulsión para la vivencia de los saberes tradicionales. Esos saberes,
heredados de un pasado común, provocaron/articularon/accionaron una lucha en contra de la
hegemonía impuesta por el colonizador y sus formas de homogenización del conocimiento, de
la cultura y de la vida, De esta manera, con base en los resultados de este estudio, que articula autores decoloniales y autores que tratan de la lengua como discurso, es posible
afirmar que los Chiquitano, al accionar la lengua materna que estaba guardada en su
memoria, lograron llegar a la morada de su ser y paulatinamente establecer un proceso
decolonial, demarcando su identidad y su lugar de pertenencia. Eso porque, colectivamente,
actuaron y promovieron la interacción de las diferentes generaciones del pueblo.
Reflexionando, fueron reencontrándose, constituyéndose a sí mismos y a su “nuevo” mundo.
Con la solicitud de una escuela propia para ellos, produjeron ciencia. Valorando el
conocimiento ancestral, definieron el currículo y las prácticas pedagógicas. Registraron, así, su
cultura, que estaba dormida en la memoria de la lengua. Produjeron una pedagogía autoral y
de enfrentamiento. La valoración de su saber y de su ser creó las posibilidades de lucha frente
al poder dominante. El bilingüismo de memoria fue la base orientadora para la formación de
los profesores y de sus prácticas pedagógicas, así como para la formación de una identidad.
Todo eso, en conjunto, propició el resurgimiento de un “ser más” (FREIRE, 2014) y provocó la
vitalización sociocultural de los Chiquitano de Brasil en el Portal do Encantado- MT. / Como marcar uma identidade étnica apagada, adormecida, silenciada em virtude do processo colonizador? No caso dos Chiquitano do Portal do Encantado-MT, que tiveram de se posicionar como indígenas para terem o direito de permanecer em seu território, a primeira estratégia foi acionar a língua materna que estava refugiada na memória dos mais velhos. E é disso que esta tese trata, ao apresentar como, por meio do “bilinguismo de memória” , esse povo conseguiu desencadear um processo interativo de resistência, posicionamento cultural e político de afirmação da identidade. Identidade essa que os lembradores (anciãos) puderam
reconstituir, dado o ponto unitário (pertencimento) comum de representação e de impulsão
para a vivência dos saberes tradicionais. Esses saberes, herdados de um passado comum,
provocaram/articularam/acionaram uma luta em face da hegemonia imposta pelo colonizador
e suas formas de homogeneização do conhecimento, da cultura e da vida. Assim, com base
nos resultados deste estudo, que enreda autores decoloniais e autores que tratam a língua
como discurso, é possível afirmar que os Chiquitano, ao acionarem a língua materna que
estava guardada em sua memória, puderam chegar à morada do seu ser e gradativamente
estabelecer um processo decolonial, demarcando sua identidade e seu lugar de
pertencimento. Isso porque, coletivamente, agiram e promoveram a interação das diferentes
gerações do povo. Refletindo, foram se reencontrando, constituindo-se a si mesmos e o seu
“novo” mundo. Ao demandarem uma escola própria para eles, produziram ciência.
Valorizando o conhecimento ancestral, definiram o currículo e as práticas pedagógicas.
Registraram, assim, a sua cultura, que estava adormecida na memória da língua. Produziram
uma pedagogia autoral e de enfrentamento. A valorização do seu saber e do seu ser criou as
possibilidades de luta diante do poder dominante. O bilinguismo de memória foi a base
orientadora para a formação dos professores e para a fundamentação de suas práticas
pedagógicas, assim como para a afirmação de uma identidade. Tudo isso, associado,
propiciou o ressurgimento de um “ser mais” (FREIRE, 2014) e provocou a vitalização
sociocultural dos Chiquitano do Brasil no Portal de Encantado-MT.

Previous issue date: 2016-05-06 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / To provide an education that can form critical citizens, active and transformers of society, far from being a contemporary challenge, it permeates debates and inspires educational theories long ago. One of the proposals to contribute to the achievement of this goal is the expansion of the school day. Although the debates on the subject can refer to an idea of recent and innovative proposal, in Brazil, experiences with full-time education focused for less economically favored social classes are realities for at least five decades. During this period, there were beginnings and closures cycles with these experiences. However, although there are several debates between advocates and opponents of this educational policy, there are not so many researches that address the impacts of these activities for teachers and students involved in these proposals. Through research that discusses and reflects on expansion programs of the school day, it is expected to be possible to ascertain whether the practice performed contributes to the goals proposed for the program. In this sense, through this study, it is intended to determine whether the activities in the area of environmental education, linked to programs of expansion of the school day in state schools of Cascavel-PR, contribute to the achievement of the main objective of the journey expansion programs school: reduce educational inequalities (BRAZIL, 2010). Therefore, Scientific Literacy indicators will be used to enable verifying the level of scientific literacy of students in the subjects addressed in the extracurricular activities they are enrolled. Analysis of the legislation was made which regulates the expansion of the school day, in the proposals of activities in the field of environmental education and also interviews with teachers and students involved in the activities. The different stages of the research show that some gaps in the legislation that regulates the extracurricular activities can negatively impact the development and results of the activities. Among the five analyzed activities, it was possible to realize the contribution of only one for Scientific Literacy of the students. It is noticed that there is still a long way to go in order that the extracurricular activities, at least in most cases, contribute to student learning and, consequently, for education. / Proporcionar uma educação que possa formar cidadãos críticos, atuantes e transformadores da sociedade, longe de ser um desafio contemporâneo, há muito permeia debates e inspiram teorias educacionais. Uma das propostas que visam a contribuir para o alcance desse objetivo é a ampliação da jornada escolar. Embora os debates acerca do tema possam remeter a uma ideia de proposta recente e inovadora, no Brasil, experiências com o ensino em tempo integral voltado para classes sociais menos favorecidas economicamente são realidades há pelo menos cinco décadas. Nesse período, houve inícios e encerramentos de ciclos com essas experiências. No entanto, embora haja vários debates entre os defensores e opositores dessa política educacional, não há muitas pesquisas que contemplem os impactos dessas atividades para professores e alunos envolvidos nessas propostas. Através de pesquisas que discutam e reflitam sobre programas de ampliação da jornada escolar, espera-se ser possível verificar se a prática realizada contribui para os objetivos propostos para o programa. Neste sentido, através da presente pesquisa, pretendeu-se verificar se as atividades na área de Educação Ambiental, vinculadas aos programas de ampliação de jornada escolar nas escolas estaduais de Cascavel-PR, contribuem para o alcance do principal objetivo dos programas de ampliação da jornada escolar: diminuir as desigualdades educacionais (BRASIL, 2010). Para tanto, os indicadores da Alfabetização Científica serão utilizados para possibilitar verificar o nível da Alfabetização Científica dos alunos nos temas abordados nas atividades em contraturno em que estão matriculados. Foram realizadas análises da legislação que regulamenta a ampliação da jornada escolar, nas propostas das atividades na área de Educação Ambiental e também entrevistas com professores e alunos envolvidos nas atividades. As diferentes etapas da pesquisa mostraram que algumas lacunas na legislação que regulamenta as atividades em contraturno podem impactar de forma negativa o desenvolvimento e resultados das atividades. Dentre as cinco atividades analisadas, foi possível perceber a contribuição de apenas uma para a Alfabetização Científica dos alunos. Percebe-se que ainda há um longo caminho a ser percorrido para que as atividades contraturno, pelo menos em sua maioria, contribuam para aprendizagem dos alunos e, consequentemente, para a Educação

Previous issue date: 2017-11-27 / A presente dissertação foi desenvolvida no âmbito do Mestrado Profissional do Programa de Pós-Graduação em Gestão e Avaliação da Educação Pública (PPGP), do Centro de Políticas Públicas e Avaliação da Educação da Universidade Federal de Juiz de Fora (CAEd/UFJF). O caso de gestão a ser estudado discutiu as dificuldades na implementação do Projeto de Educação Integral, em uma escola na cidade de Ribeirão das Neves/MG. Diante disso, a pergunta norteadora desse estudo de caso é: “quais os desafios para implementação do Projeto de Educação Integral na Escola Estadual Pedro Bandeira?”. A hipótese, ora defendida, é a de que as dificuldades de implementação do Projeto de Educação Integral vivenciadas pela Escola Estadual Pedro Bandeira estão relacionadas a problemas na organização do Projeto e em sua implementação, mais especificamente no repasse de recursos financeiros, por parte do Governo Federal. Além disso, as dificuldades também estão relacionadas à ausência de um planejamento da gestão da escola, que seja capaz de lidar com essas dificuldades, como a ausência de um supervisor pedagógico exclusivo para as turmas de Educação Integral e a falta de capacitação dos docentes para ministrar as oficinas previstas pelo projeto. Na tentativa de responder a essa questão, o objetivo geral desse estudo está pautado na descrição, análise e proposição de ações para os problemas apresentados na implementação do Projeto de Educação Integral na Escola Estadual Pedro Bandeira. Já os objetivos específicos definidos foram: i) descrever o Projeto de Educação Integral na Escola Estadual Pedro Bandeira; ii) analisar os problemas que vem dificultando a implementação das ações do projeto de Educação Integral nesta escola e, iii) propor ações que levem a escola analisada a minimizar os problemas na implementação do Projeto de Educação Integral. Para tanto, utilizamos, como metodologia, a pesquisa qualitativa, e como instrumentos a entrevista com os atores envolvidos com a iniciativa. A análise contou com o embasamento teórico de autores como: Moll (2012), que analisa o direito a outros tempos e espaços educativos; Luck (2009; 2010), com reflexões sobre os desafios da liderança nas escolas; Ball (2001), com análises sobre políticas públicas; e Mainardes (2006) e Cóssio (2010), com a abordagem dos ciclos de Políticas. Ainda, Silva (2013), que aborda o papel da Educação Integral; Felix (2012), Pimenta (1991), Rangel e Ferreira (2008) e Muribeca (2002), autores que abordam a formação profissional; Draibe (2001), com reflexões sobre a capacitação; e Vieira (2002), refletindo sobre o trabalho com as oficinas. A análise desse estudo de caso nos permitiu a elaboração de um Plano de Ação Educacional (PAE) que busca minimizar os problemas encontrados na implementação do Projeto de Educação Integral na Escola Estadual Pedro Bandeira. / This dissertation was developed under the Professional Master's Program of the Graduate Program in Management and Evaluation of Public Education (PPGP), the Center for Public Policies and Education Evaluation of the Federal University of Juiz de Fora (CAEd / UFJF). The management case to be studied discussed the difficulties in implementing the Integral Education Project, in a school in the city of Ribeirão das Neves / MG. Faced with this, the guiding question of this case study is: "What are the challenges for the implementation of the Integral Education Project at the Pedro Bandeira State School?". The hypothesis defended here is that the difficulties of implementing the Integral Education Project experienced by the Pedro Bandeira State School are related to problems in the organization of the Project and its implementation, more specifically in the transfer of financial resources, by the Government Federal. In addition, the difficulties are also related to the lack of school management planning that is capable of dealing with these difficulties, such as the absence of an exclusive pedagogical supervisor for Integral Education classes and the lack of capacity of teachers to minister the workshops planned by the project. In an attempt to answer this question, the general objective of this study is based on the description, analysis and proposition of actions for the problems presented in the implementation of the Integral Education Project at the Pedro Bandeira State School. The specific objectives defined were: i) to describe the Integral Education Project at the Pedro Bandeira State School; ii) analyze the problems that are making it difficult to implement the actions of the Integral Education project in this school; and iii) propose actions that lead the school analyzed to minimize the problems in the implementation of the Integral Education Project. For that, we used, as methodology, the qualitative research, and as instruments the interview with the actors involved with the initiative. The analysis relied on the theoretical basis of authors such as: Moll (2012), which analyzes the right to other times and educational spaces; Luck (2009; 2010), reflecting on the challenges of leadership in schools; Ball (2001), with analyzes on public policies; and Mainardes (2006) and Cósio (2010), with the approach of the cycles of Policies. Still, Silva (2013), which addresses the role of Integral Education; Felix (2012), Pimenta (1991), Rangel and Ferreira (2008) and Muribeca (2002), authors who approach vocational training; Draibe (2001), with reflections on training; and Vieira (2002), reflecting on the work with the workshops. We found that the analysis of this study allowed us to elaborate an Educational Action Plan that seeks to minimize the problems encountered in the implementation of the Integral Education Project at the Pedro Bandeira State School.

Processus identitaires personnels et professionnels et trajectoire migratoire chez des médecins diplômés à l'étranger : une étude exploratoire en France et au Brésil / Personal and professional identity processes and migratory trajectory among foreign doctors : exploratory research in France and BrazilBaraud, Marie 04 February 2016 (has links)
Cette recherche vise à mettre en évidence les transformations des processus identitaires intervenant chez des médecins diplômés à l’étranger et exerçant en France et au Brésil. Nous avons appuyé notre travail sur une approche dynamique et adaptative de l’identité personnelle, en particulier à travers l’identité dialogique et l’identité narrative. De plus, dans la mesure où ce travail fait intervenir de manière importante le contexte professionnel, il nous semblait pertinent de faire intervenir aussi la question de l’identité professionnelle et de ses liens avec la reconnaissance. Enfin, l’interculturalité étant centrale dans cette problématique, nous avons choisi de l’aborder sous l’angle de l’identité interculturelle et de l’interculturation. L’objectif de cette recherche est de caractériser les processus identitaires présents chez médecins diplômés à l’étranger, confrontés à une situation de diversité culturelle dont la gestion a des rapports importants avec leurs processus identitaires personnels et professionnels. En particulier, nous cherchons à comprendre les processus psychiques permettant au sujet de donner sens à son expérience migratoire afin de se l’approprier et d’engager une transformation de son identité. Nous travaillerons également sur les obstacles rencontrés par les sujets et à établir la place de la reconnaissance au sein de ces différents processus. Enfin, l’analyse des données contribue à démontrer les processus d’influence mutuelle intervenant entre l’appartenance culturelle et le contexte d’activité professionnelle. Quatre méthodes de construction et d’analyse des données ont été combinées afin de répondre à ce questionnement. Dans un premier temps, nous avons réalisé un questionnaire visant à caractériser notre population et à recenser les facteurs déclencheurs d’une migration. Ensuite, nous avons conduit des entretiens de type biographique afin d’amener le sujet à « se raconter », à mettre en récit sa trajectoire personnelle, en rapport avec des aspects identitaires. Puis, en fin d’entretien, nous avons proposé aux sujets de visionner un ensemble d’extraits vidéo issus d’un documentaire et de deux reportages afin de les confronter à plusieurs points de vue et situations en vue de faire émerger une réflexion sur leur vécu. Enfin, nous avons effectué une analyse documentaire d’un ensemble d’articles de presse. 89 médecins ont répondu au questionnaire, 43 en France et 46 au Brésil. Huit récits de vie ont été menés en France avec des sujets âgés de 36 à 71 ans, trois femmes et cinq hommes parmi lesquels deux avaient obtenu leur diplôme dans un pays de l’UE et six hors de l’UE. Nous avons également analysé un corpus de 25 articles de presse et trois reportages télévisés. L’influence de la reconnaissance du diplôme sur la trajectoire et les processus identitaires de ces sujets ainsi que l’importance de la langue, du genre et du projet migratoire sur ces processus ont été clarifiés par l’analyse de l’ensemble des données. L’analyse des trajectoires personnelles, professionnelles et migratoires des sujets qui ont participé à cette recherche présente l’impact d’un ensemble de facteurs culturels, sociaux et institutionnels sur des événements biographiques — individuels. Ces deux dimensions — l’individuel et le culturel - se trouvent en constant dialogue et en constante co-évolution pour rendre chaque trajectoire unique et semblable, processus centrale à la formation de l’identité de chaque individu. / This research aims at investigating the changes that occur within the identity processes of physicians with a foreign diploma working in France and Brazil. Our work is based on a dynamic and adaptive approach of personal identity, specifically through the concept of dialogical self but also through the narrative identity approach. Since we also focus importantly on what happens in the professional environment, we also used theories related to professional identity and its relations with recognition. Finally, since the intercultural question is central in this research, we have chosen to include the intercultural identity theory and the concept of interculturation. This research aims at identifying and understanding the identity processes presented by medical doctors confronted to a changing cultural and professional context. We specifically intend to understand the psychological processes which allow the subject to give a meaning to his experience and make it his to start a transformation of his identity. We also focus on the obstacles the subject has to deal with, in particular regarding recognition. Finally, we intend to show the processes of mutual influence occurring between cultural belonging and professional context. We have crossed four methods to build and analyze our data. At first, we have used a questionnaire to characterized our population from a socio-demographic point of view and reunite all the factors which explain their migration. Then, we have conducted eight biographical interviews to encourage the subject to build a self-narrative. In the last phase of the interview, the have subjects have been shown four short videos from three documentaries to confront them to different points of view and situations and have them reflect on their own experience. We also included a documentary analysis using press articles regarding the Brazilian context. We obtained 89 answers to the questionnaire, 43 in France and 46 in Brazil. We conducted 8 narrative interviews, with physicians aged between 36 and 71, 3 women and 5 men, among which 2 had a European Union diploma and 6 had a diploma from outside the UE. Our analysis has shown that the validation of the diploma has a great impact on each individual’s recognition and identity related processes. This recognition aspects are also mediated by factors such as gender, language and cultural through dialogical relationships involving the subject.

Prototypage virtuel incrémental des actionneurs électromécanique pour la synchronisation en position / Incremental Virtual Prototyping of Electromechanical Actuators for Position SynchronizationFu, Jian 06 July 2016 (has links)
Dans le domaine de l'aéronautique, les concepts basés sur l’usage étendu de l'électricité dans les aéronefs plus électriques (MEA) et même tout électriques (AEA) font appel à des actionneurs électromécaniques (EMA) en replacement des actionneurs servo-hydrauliques conventionnels (HSA). Lorsque les EMA sont utilisés pour des applications d'actionnement critique comme les commandes de vol, certains problèmes spécifiques liés à l’équilibre thermique, l'inertie réfléchie, le mouvement parasite dû aux élasticités structurelles, la réponse aux fautes (grippage et rupture) et la synchronisation d’EMA actifs sur charges indépendantes ne peuvent être ignorés. La simulation apporte un support indéniable à la conception pour l’évaluation et la validation des concepts. A cet effet, il est nécessaire de développer des prototypes virtuels des EMA avec une vision système et de façon structurée pour répondre aux besoins des ingénieurs. Malheureusement, les phénomènes physiques qui apparaissent dans les EMA sont multidisciplinaires, couplés et fortement non linéaires. De nombreux logiciels commerciaux de simulation système multi-domaines sont désormais disponibles. Cependant, le processus de modélisation et les besoins des ingénieurs sont rarement pris en compte selon une vision globale, en raison du manque d'approches scientifiques pour la définition d’architectures, la modélisation incrémentale et l’amélioration de l’implémentation numérique des modèles. Dans cette thèse, le prototypage virtuel de l'EMA est adressé en utilisant le formalisme Bond-Graph. De nouvelles approches sont proposées pour permettre la modélisation incrémentale de l'EMA en vue de fournir des modèles pour la synthèse de la commande, l’évaluation de la consommation d'énergie, l'analyse thermique, le calcul des forces de réaction, la simulation de la pollution du réseau d'alimentation électrique, la réponse aux fautes et l'influence de la température. L’intérêt des modèles proposés est illustré sur l’exemple de la synchronisation de position de deux EMA actionnant des charges indépendantes. / In the aerospace field, the concepts based on extended use of electricity in “More Electric Aircraft” (MEA) and even “All Electric Aircraft” (AEA), involve electromechanical actuators (EMAs) to replace conventional hydraulic servo actuators (HSAs). When EMAs are used for safety-critical actuation applications like flight controls, some specific issues related to thermal balance, reflected inertia, parasitic motion due to compliance, response to failure (jamming and free-run) and synchronization of EMAs driving independent loads cannot be ignored. The simulation-aided design process can efficiently support the assessment and validation of the concepts fixing these issues. For that, virtual prototypes of EMAs at system-level have to be developed in a structured way that meets the engineers’ needs. Unfortunately, the physical effects governing the EMAs behavior are multidisciplinary, coupled and highly nonlinear. Although numerous multi-domain and system-level simulation packages are now available in the market of simulation software, the modelling process and the engineers’ needs are rarely addressed as a whole because of lack of scientific approaches for model-based architecting, multi-purpose incremental modelling and model implementation for efficient numerical simulation. In this thesis, the virtual prototyping of EMAs is addressed using the Bond-Graph formalism. New approaches are proposed to enable incremental modelling of EMAs that provides models supporting control design, energy consumption and thermal analysis, calculation of reaction forces, power network pollution simulation, prediction of response to faults and influence of temperature. The case of preliminary design of EMAs position synchronization is used to highlight the interests and advantages of the proposed process and models of EMAs.

Rectifier And Inverter System For Driving Axial Flux BLDC Motors In More Electric Aircraft ApplicationDe, Sukumar 01 1900 (has links) (PDF)
In the past two decades the core aircraft technology is going through a drastic change. The traditional technologies that is almost half a century old, is going through a complete revamp. In the new “More Electric Aircraft” technology many mechanical, pneumatic and hydraulic systems are being replaced by electrical and power electronic systems. Airbus-A380, Boeing B-787 are the pioneers in the family of these new breed of aircrafts. As the aircraft technology is moving towards “More Electric”, more and more electric motors and motor controllers are being used in new aircrafts. Number of electric motor drive systems has increased by about ten times in more electric aircrafts compared to traditional aircrafts. Weight of any electric component that goes into aircraft needs to be low to reduce the overall weight of aircraft so as to improve the fuel efficiency of the aircraft. Hence there is an increased need to reduce weight of motors and motor controllers in commercial aircraft.
High speed ironless axial flux permanent magnet brushless dc motors are becoming popular in the new more-electric aircrafts because of their ability to meet the demand of light weight, high power density, high efficiency and high reliability. However, these motors come with very low inductance, which poses a big challenge to the motor controllers in controlling the ripple current in motor windings. Multilevel inverters can solve this problem. Three-level inverters are proposed in this thesis for driving axial flux BLDC motors in aircraft. Majority of the motors in new more electric aircrafts are in the power range of 2kW to 20kW, while a few motor applications being in the range of 100kW to 150kW. Motor controllers in these applications run from 270Vdc or 540Vdc bus which is the standard in new more electric aircraft architecture.
Multilevel Inverter is popular in the industry for high power and high voltage applications, where high-voltage power switching devices like IGBT, GTO are popularly used. However multilevel inverters have not been tried in the low power range which is appropriate for aircraft applications. A detail analysis of practical feasibility of constructing three-level inverter in lower power and voltage level is presented in this thesis. Analysis is presented that verify the advantages of driving low voltage and low power (300Vdc to 600Vdc and less than 100kW) motors with multilevel inverters. Practical considerations for design of MOSFET based three-level inverter are investigated and topological modifications are suggested. The effect of clamping diodes in the diode clamped multilevel inverters play an important role in determining its efficiency. SiC diodes are proposed to be used as clamping diodes. Further, it is realised that power loss introduced by reverse recovery of MOSFET body diode prohibits use of MOSFET in hard switched inverter legs. Hence, a technique of avoiding the reverse recovery losses of MOSFET body diode in three-level NPC inverter is conceived. The use of proposed multilevel inverter topology enables operation at high switching frequency without sacrificing efficiency. High switching frequency of operation reduces the output filter requirement, which in turn helps reducing size of the inverter. In this research work elaborate trade-off analysis is done to quantify the suitability of multilevel inverters in the low power applications.
For successful operation of three-level NPC inverter in aircraft electrical system, it is important for the DC bus structure in aircraft electric primary distribution system to be compatible to drive NPC inverters. Hence a detail study of AC to DC power conversion system as applied to commercial aircraft electrical system is done. Multi-pulse rectifiers using autotransformers are used in aircrafts. Investigation is done to improve these rectifiers for future aircrafts, such that they can support new technologies of future generation motor controllers. A new 24-pulse isolated transformer rectifier topology is proposed. From two 15º displaced 6-phase systems feeding two 12-pulse rectifiers that are series connected, a 24-pulse rectifier topology is obtained. Though, windings of each 12-pulse rectifiers are isolated from primary, the 6-phase generation is done without any isolation of the transformer windings. The new 24-pulse transformer topology has lower VA rating compared to standard 12-pulse rectifiers. Though the new 24-pulse transformer-rectifier solution is robust and simple, it adds to the weight of the overall system, as compared to the present architecture as the proposed topology uses isolated transformer. Non-isolated autotransformer cannot provide split voltage at the dc-link that creates a stable mid-point voltage as required by the three-level NPC inverter. Hence, a new front-end AC-DC power conversion system with switched capacitor is conceived that can support motor controllers driven by three-level inverters. Laboratory experimental results are presented to validate the new proposed topology. In this proposed topology, the inverter dc-link voltage is double the input dc-link voltage.
An intense research work is performed to understand the operation of Trapezoidal Back EMF BLDC motor driven by three-Level NPC inverter. Operation of BLDC motor from three-Level inverter is primarily advantageous for low inductance motors, like ironless axial flux motors. For low inductance BLDC motor, very high switching frequency is required to limit the magnitude of ripple current in motor winding. Three-level inverters help limiting the magnitude of motor ripple current without increasing the switching frequency to very high value. Further, it is analysed that dc link mid-point current in three-level NPC inverter for driving trapezoidal BLDC motor has a zero average current with fundamental frequency same as switching frequency. Because of this, trapezoidal BLDC motors can easily be operated from three-level NPC inverter without any special attention given to mid-point voltage unbalance. One non-ideal condition arrives in practical implementation of the inverter that leads to non-zero average mid point current. Unequal gate drive dead time delays from one leg to other leg of inverter introduce dc-link mid-point voltage unbalance. For the motoring mode operation of trapezoidal BLDC motor drive, simple gate drive logic is researched that eliminates need of the gate drive dead-time, and hence solves the mid-point voltage unbalance issue. Simple closed loop control scheme for mid-point voltage balancing also is also proposed. This control scheme may be used in applications where very precise control of speed and torque ripple is warranted.
All the investigations reported in this thesis are simulated extensively on MATHCAD and MATLAB platform using SIMULINK toolbox. A laboratory experimental set-up of three-Level inverter driving axial flux BLDC motor is built. The three-level inverter, operating from 300Vdc bus is built using 500V MOSFETs and 600V SiC diodes. All the control schemes are implemented digitally on digital signal processor TMS320F2812 DSP platform and GAL22V10B platforms. Experimental results are collected to validate the theoretical propositions made in the present research work.
At the end, in chapter 5, some future works are proposed. A new external voltage balance circuit is proposed where the inverter dc-link voltage is same as the input dc-link voltage. This topology is based on the resonant converter principle and uses a lighter resonant inductor than prior arts available in literature. Detail simulation and experimentation of this topology may be carried out to validate the industrial benefits of this circuit. It is also thought that current source inverters may work as an alternative to voltage source inverters for driving BLDC motors. Current source inverters eliminate use of bulky DC-link capacitors. Long term reliability of current source inverters is higher than voltage source inverters due to the absence of possibility of shoot-through. Further, in voltage source inverters, the voltage at the motor terminal is limited by the source voltage (dc-link voltage). This issue is eliminated in current source inverters. An interface circuit is conceived to reduce the size of dc-link inductors in current source inverters, pending detail analysis and experimental verification. The interface circuit bases its fundamentals on the principles of operation of multilevel inverters for BLDC motors that is presented in this thesis.
