La présente recherche collaborative vise à étudier les pratiques de lecture à haute voix d’enseignantes expertes et leur influence sur le développement de l’habileté des élèves du préscolaire à faire des inférences. Plus précisément, nous décrivons les interventions, lors des lectures à haute voix, de quatre enseignantes expertes que nous avons formées pour travailler la compréhension inférentielle et les comparons à celles de deux enseignantes expertes non formées (objectif 1). Puis, nous examinons l’influence de leurs pratiques de lecture à haute voix sur le développement de l’habileté à faire des inférences de leurs élèves (n=92) (objectif 2). Enfin, nous nous intéressons, à titre exploratoire, au potentiel de la recherche collaborative comme voie de développement professionnel des enseignants (objectif 3). Afin d’atteindre nos objectifs, nous avons observé les enseignantes à quatre reprises, lors de lectures d’albums de littérature de jeunesse. Les données obtenues à partir de ces pratiques observées ont été complétées par celles issues des pratiques déclarées des enseignantes pour toute la durée de la recherche (neuf semaines). De plus, nous avons évalué l’habileté à réaliser des inférences des élèves de ces six enseignantes à deux reprises, au début et à la fin de la recherche. Finalement, les enseignantes ont rempli deux questionnaires écrits sur l’impact de cette recherche sur leurs pratiques, l’un à la fin de la recherche et l’autre deux ans après celle-ci. Nos résultats indiquent que si toutes les enseignantes travaillaient les inférences, il existe cependant des différences notables dans leur façon de mener ce travail. Trois des enseignantes formées (enseignantes 1, 2 et 3) ont majoritairement privilégié la co-élaboration du sens des épisodes implicites et se sont montrées très efficaces pour soutenir leurs élèves dans ce travail de construction du sens. L’autre enseignante formée (enseignante 4), en raison d’une appropriation difficile du contenu de la formation, n’est pas parvenue à offrir à ses élèves un étayage adéquat, malgré ses nombreuses tentatives pour les amener à faire des inférences. Les enseignantes non formées (enseignantes 5 et 6) ont, quant à elles, misé plus fréquemment sur la transmission du sens des épisodes implicites et ont également soutenu moins efficacement leurs élèves dans l’élaboration du sens. Ces différences dans la façon de travailler les inférences se sont répercutées sur la progression des élèves entre le début et la fin de la recherche. Ceux des enseignantes 1, 2 et 3 obtiennent des résultats significativement supérieurs à ceux des trois autres enseignantes. Ainsi, il ne suffit pas de travailler les inférences lors des lectures à haute voix pour assurer la progression des élèves. D’autres facteurs revêtent aussi une grande importance : le choix d’oeuvres de qualité, l’engagement des élèves dans les discussions pour co-élaborer le sens et l’étayage adéquat de l’enseignant. Enfin, il semblerait que l’activité réflexive suscitée lors d’une participation à une recherche collaborative et le soutien offert par l’étudiante-chercheuse aient donné aux enseignantes la possibilité d’apporter des changements durables dans leurs pratiques. En ce sens, la recherche collaborative paraît être une voie prometteuse pour contribuer au développement professionnel des enseignants. / This collaborative research is an attempt to study expert teachers' reading aloud practices and their impact on the development of preschool students’ ability to make inferences. First, the interventions of four expert teachers specifically trained to work inferences while reading aloud are described and compared with those of two non trained expert teachers (objective 1). Next, the impact of all teachers’ practices on the development of their students’ ability to make inferences (n=92) is examined (objective 2). Finally, we look into collaborative research as a way to support professional development for teachers (objective 3). In order to attain our objectives, we observed participant teachers four times while they were reading children’s books. Data gathered from those observations were completed with other data provided by the teachers about their practices over a nine-week period. Moreover, the ability of the students to make inferences was assessed twice: once at the beginning and once at the end of the research. Teachers also completed two written questionnaires, one at the beginning and the other 2 years after the end of this research, concerning the impacts of their participation in this research on their practices. While all teachers worked inferences with their students, our results showed that there are significant differences in the way they do it. Three of the trained teachers (number 1, 2, and 3) predominantly put emphasis on co-elaboration of the implicit episodes’ meaning and gave their students appropriate scaffolding. Because she found it difficult to assimilate training contents, the other trained teacher (number 4) failed - not without numerous attempts - to offer the same kind of scaffolding. As for the two non trained teachers (number 5 and 6), they gave preference to the transmission of the implicit episodes’ meaning, and supported their students less efficiently when they tried to elaborate it. The differences in how the work on inferences was done had an impact on students’ progression from the beginning to the end of the research. Three of the trained teachers’ students had significantly superior results in comparison to the others’. Therefore, a specific work on inferences only does not ensure that students will make progress. There are other important contributing factors: choosing quality books, students’ involvement in discussions in order to co-elaborate the text’s meaning, and appropriate scaffolding from the teacher. Finally, according to our results, a participation in a collaborative research, which promotes reflexivity and offers coaching, seems to give the teachers the opportunity to bring about long-term changes in their practices. In consequence, a participation in that type of research appears to contribute to teachers’ professional development.

Secret key generation from reciprocal multi-antenna channels is an interesting alternative to cryptographic key management in wireless systems without infrastructure access. In this work, we study the secret key rate for the basic source model with a MIMO channel. First, we derive an expression for the secret key rate under spatial correlation modelled by the Kronecker model and with spatial precoding at both communication nodes. Next, we analyze the result for uncorrelated antennas to understand the optimal precoding for this special case, which is equal power allocation. Then, the impact of correlation is characterized using Majorization theory. Surprisingly for small SNR, spatial correlation increases the secret key rate. For high SNR, the maximum secret key rate is achieved for uncorrelated antennas. The results indicate that a solid system design for reciprocal MIMO key generation is required to establish the secret key rate gains.

In this Master’s thesis, I document my experience working with members of the W̱SÁNEĆ Nation in their efforts to revitalize the reef net fishery. As part of this research project, I interviewed W̱SÁNEĆ community members, and I created a digital map of reef net fishing locations (SWELSWÁLET). In each of these interviews, different W̱SÁNEĆ community members chose to frame reef net fishing differently, and they highlighted specific and unique “alternative political approaches” toward W̱SÁNEĆ cultural resurgence (Kew & Miller 1999:58-59). Despite these differences, each W̱SÁNEĆ community member that I interviewed believed that reef net fishing is something that “needs to be shared” (XA’LATE, pers. comm., June 14, 2016). In Chapter 1, I explore the variations in what specific W̱SÁNEĆ community members want shared. In Chapters 2 and 3, however, I examine the delicate cultural, political, and legal contexts that have made sharing a complicated process. In Chapter 2, I analyze how the BC Treaty Process (BCTP) has exacerbated conflicts among First Nations in British Columbia. Further, I discuss the impact that these conflicts have had on how the W̱SÁNEĆ Nation shares information with their intranational and international neighbours. In Chapter 3, I explore how my misaligned expectations of knowledge sharing in collaborative community-based research—as a white settler man—clashed with “the values and beliefs, practices and customs of [the W̱SÁNEĆ Nation]” (L. Smith 2012:15-16; Lassiter 2005). I also make recommendations for how settler researchers in the future should proceed with research projects in these contexts. / Graduate / 2019-12-06

Regarding this change, the role of the principal is identified as a fundamental role in the upcoming of inclusive schools, requiring new abilities, knowledge and development in order to face the challenge of managing those schools. This work encompasses a research experience developed throughout a partnership with a school, striving to build up elements of reference to the management of the school regarding the diversity issue. In order to accomplish this study we have done a comprehensive bibliographical account involving theoretical axis and researches on the themes of school, inclusion and the new kinds of school organization facing diversity. Moreover, studies on culture, diversity, difference, and the principles implied in change theory and the foundations of management towards an inclusive school were added in the bibliographical research. The research itself aimed to develop, in partnership with a city public school, an intervention program considering the school management regarding diversity issues, having as a starting point the constitution of a co-participative management. The methodology used was the collaborative action-research which is featured by the sharing of the knowledge among all participants of the process, so that, together, they can change an initial situation into a better one. The study lasted two years and a half and the results showed that a shared management may be beneficial to the constitution of an inclusive school. It is fundamental, though, that the school members learn to work together and seek, increasingly, the improvement of collaborative practices. In the specific school researched, we have considered as a key issue, the changing of management practices, specifically the way the guidance of daily actions was developed. This guidance allowed the improvement of some changing issues: the introduction of a collaborative action between the coordination and the teachers, mainly those teachers who were coached by members of the research “Learning Management in Diversity” team; the reorganization of planning actions; the reinforcement of actions in the issue of participative management; investment in the diversification of pedagogical equipment and in school facilities; the systematization of the actions of the director’s board throughout the sharing of the decision taking process; and the investment in the development of teachers and coordinators. The changes occurred along the research process lead us to say that the management model adopted in the school did not suffice the need for change from a traditional cultural pedagogical practice still prevalent. The changes occurred did not diverge from homogenous teaching practice neither guaranteed nor corresponded with a model that moved towards the constitution of an inclusive identity that devised the improvement of teaching patterns offered to the students / As demandas educacionais atuais apontam para a necessidade de mudanças na escola para o atendimento aos alunos, levando em conta suas singularidades e necessidades individuais. Para essas mudanças, o papel do diretor é identificado como fundamental na constituição de escolas inclusivas requerendo novas habilidades, conhecimentos e formação que atenda o desafio de gerir essas escolas. Este trabalho se constituiu em uma experiência de pesquisa desenvolvida em parceria com uma escola, buscando construir elementos de referência para a organização e gestão da escola na diversidade. Para a realização desse estudo, empreendemos uma revisão bibliográfica contemplando eixos teóricos e pesquisas realizadas acerca da discussão sobre a escola, a inclusão e as novas formas de organização frente à diferença e a diversidade além dos estudos que discutem sobre a cultura, educação e diferença e os pressupostos implicados na teoria da mudança e nos fundamentos de uma gestão para a escola inclusiva. A pesquisa teve por objetivo desenvolver, em parceria com uma escola publica municipal, uma experiência de intervenção que considerasse a gestão da aprendizagem na diversidade, tendo como ponto de partida à constituição de uma gestão co-participativa. A metodologia utilizada foi a pesquisa-ação colaborativa que se caracteriza pelo compartilhamento do saber na qual todos os participantes do processo, juntos, promovem ações para transformar uma situação inicial num estado desejado. O estudo teve duração de dois anos e meio e os resultados mostraram que a gestão compartilhada é benéfica à constituição da escola inclusiva sendo fundamental que os membros da escola aprendam a trabalhar junto e busquem, cada vez mais, o aperfeiçoamento de práticas de colaboração. Na escola pesquisada, consideramos como ponto fundamental para a mudança na gestão, à forma como foi desenvolvido o acompanhamento das ações cotidianas. Esse acompanhamento permitiu o avanço em alguns pontos que destacamos na seqüência: a interiorização da cultura de cooperação entre a gestão da escola e os professores, especialmente aqueles que foram acompanhados por membros da pesquisa Gestão da Aprendizagem na Diversidade; a criação da cultura do acolhimento a todos os alunos por parte da gestão da escola; a reorganização das ações de planejamento; reforço das ações no âmbito da gestão participativa; investimento na diversificação dos equipamentos pedagógicos e na infra-estrutura da escola; a sistematização das ações da direção através da partilha e reciprocidade na tomada de decisões; e investimento na formação dos professores e membros a equipe de gestão. As mudanças acontecidas ao longo da pesquisa nos impulsionam a dizer que o modelo de administração adotado na escola não foi suficiente para provocar a mudança da cultura pedagógica tradicional ainda prevalecente. As transformações ocorridas não romperam totalmente com os padrões de ensino homogêneos e nem garantiram e corresponderam a um movimento efetivo na constituição de uma identidade inclusiva própria bem como na melhoria dos padrões de ensino ao alcance de todos os alunos

No. of bitstreams: 1 TeseVLMFC.pdf: 3055947 bytes, checksum: 0297b0cf69bb14d4a03df3405d273458 (MD5) Previous issue date: 2004-12-20 / Every day the school faces the challenge of teaching with quality all the students but without having a lot of success in working with the diversity because of the verified absence of a serious and effective politics of inclusive education in most of the school systems. In the students with special education needs case, the access to a common class in regular schools has being minimum and there are several no solved questions on how the philosophical beginning of school inclusion could happen in practice, not only promoting the socialization but also those students' school income. An alternative thoroughly emphasized has been the need of teachers' qualification who have already been working with those students in their groups. And the scientific literature of more experienced countries in practices of school inclusion has being choosed the collaborative work in the school context as a strategy in ascension, that has shown effectiveness to solve several problems related to the process of teaching and learning and to promote the educators' personal and professional development. The objective of this study consisted in verifying the implications of one way of collaborative work in the school that would be denominated "collaborative teaching" which involves the establishment of a partnership basically among teachers of regular and special teaching. The study was driven at two common schools of elementary teaching, and more directly in four groups from 1st to 4th grades where six students with mental deficiency were inserted. Before and after the intervention, academic and social acting measures of all the students of the four groups were collected. The intervention based in the collaborative teaching involved the establishment of a partnership with the teacher of the special teaching systematic support inside the common class together with the teacher of the regular teaching, in some days of the week and activities planned extra-class, reflection on the practice, meetings with relatives, meetings with the school group and driven studies. The intervention in each group lasted from one semester to one year, and the study had total duration of two years, evolving the attendance in the four groups. After the intervention stage measures of social validity based on the teachers' and families´ opinions on the teaching collaborative were collected. The intervention based on collaborative teach involved a partnership determined by the sistematic support of the special education teacher inside the usual classroom, with the regular education teacher, in some days of the week, besides the extra-class activities with planning, reflexion about the practice, meetings with the student´s families, meetings with the coletive of school and conducted study. The intervention in each group, last since six months to one year, and all the study lasted two years including the four groups attendance. After the intervention stage, social information were colected based on teacher´s and families´s statement about collaborative teaching. The results indicate that all the six students had evoluted in the acting even academic or in socialization, although considerable discrepancy is observed in comparison with the average yield of the group. For all of the teachers the teaching collaborative made possible personal and professional development but some difficulties appeared mainly in the united activities in the classroom atmosphere. The relatives considered that their children had improvements and they felt safer for the fact of having two teachers in the room. The study also indicated that the collaborative teaching was evaluated as an effective strategy of the teachers' personal and professional development involved in practices that seek the school inclusion. As implications of the study, we discuss about the need of changes in the culture of initial and continuous formation of common and special education teachers to prepare them to really act in collaboration. It is still discussed the new role of the special education teacher to act priory as support centered in the common class and not just in services that involve the students' retreat with special education needs of the group or exclusively in segregated services. / Cada dia mais a escola enfrenta o desafio de ensinar com qualidade todos os alunos, mas, sem ter muito sucesso em lidar com a diversidade porque se constata a ausência de uma política séria e efetiva de educação inclusiva, na maioria dos sistemas escolares. No caso dos alunos com necessidades educacionais especiais, o acesso a uma classe comum, nas escolas, ainda continua mínimo e persistem várias questões não resolvidas sobre como operacionalizar na prática o princípio filosófico da inclusão escolar, de modo a promover, não apenas a socialização, mas também, o rendimento escolar desses alunos. Uma alternativa amplamente enfatizada tem sido a necessidade de melhorar a qualificação dos professores que já se defrontam com esses alunos em suas turmas. E, a literatura científica de países mais experientes em práticas de inclusão escolar aponta o trabalho colaborativo no contexto escolar como uma estratégia em ascensão que tem se mostrado efetiva, tanto para solucionar problemas diversos relacionados ao processo de ensino aprendizagem quanto para promover o desenvolvimento pessoal e profissional dos educadores. O objetivo deste estudo consistiu em verificar as implicações de uma das formas de trabalho colaborativo na escola, denominado ensino colaborativo que envolve basicamente o estabelecimento de uma parceria entre professores de ensino comum e especial. O estudo foi conduzido em duas escolas de ensino fundamental, mais diretamente, em quatro turmas de 1ª a 4ª série nas quais estavam inseridos seis alunos com deficiência mental. Antes e depois da intervenção foram coletadas medidas de desempenho acadêmico e social de todos os alunos das quatro turmas. A intervenção baseada no ensino colaborativo envolveu o estabelecimento de uma parceria com apoio sistemático do professor de ensino especial dentro da classe comum, juntamente com o professor do ensino comum, em alguns dias da semana, além de atividades extra-classe de planejamento, reflexão sobre a prática, reuniões com familiares, reuniões com o coletivo da escola e estudos dirigidos. A intervenção em cada turma durou de um semestre a um ano, e o estudo teve duração total de dois anos, compreendendo o acompanhamento nas quatro turmas. Após a etapa de intervenção foram coletadas medidas de validade social baseada nas opiniões das professoras e das famílias sobre o ensino colaborativo. Os resultados indicam que todos os seis alunos tiveram evolução no desempenho tanto acadêmico como de socialização, ainda que se observe discrepância considerável em comparação ao rendimento médio da turma. Para todas as professoras o ensino colaborativo possibilitou desenvolvimento pessoal e profissional, mas algumas dificuldades surgiram no tocante principalmente às atividades conjuntas no ambiente de sala de aula. Os familiares consideraram que seus filhos melhoraram e sentiram-se mais seguros pelo fato de ter duas professoras na sala. O estudo indicou ainda que o ensino colaborativo foi avaliado como efetivo enquanto estratégia de desenvolvimento pessoal e profissional dos professores envolvidos em práticas que visam à inclusão escolar. Como implicações do estudo discute-se a necessidade de mudanças na cultura da formação inicial e continuada de professores do ensino comum e especial de modo a prepará-los para atuar efetivamente em colaboração. Discute-se ainda a necessidade de redefinir o papel do professor de ensino especial para atuar prioritariamente como apoio centrado na classe comum e não apenas em serviços que envolvam a retirada dos alunos com necessidades educacionais especiais da turma ou, exclusivamente, em serviços segregados.

O objetivo principal desta pesquisa orientou-se pela intenção de dar visibilidade à produção brasileira em Educação de pesquisas tipo pesquisa-ação / investigação-ação, focalizando, sobretudo, a pesquisa-ação colaborativa. Essas concepções de pesquisa estimulam a aproximação entre professores e pesquisadores, por meio da colaboração em processos investigativos desenvolvidos com, para e pelos professores sobre as práticas escolares. Na maioria dos casos, tais pesquisas foram desenvolvidas nas escolas. Este estudo foi desenvolvido em quatro estágios: O primeiro é constituído por um estudo bibliográfico que objetivou indicar os teóricos que influíram nessa modalidade de pesquisa em seu enraizamento no Brasil. Para isso, tomamos alguns autores: Saul, Freire, Thiollent, Barbier, Costa, André, Nóvoa, Geraldi, Fiorentini, Pereira, Stenhouse, Elliott, Carr, Kemmis e Zeichner. Num segundo momento, fizemos um mapeamento das dissertações e teses tipo pesquisa-ação / investigação-ação produzidas nos Programas de Pós-Graduação em Educação do Brasil no período entre 1966-2002, apresentando-os em categorias e subcategorias investigadas. O terceiro é constituído por um estudo documental qualitativo sobre uma amostra de pesquisas-ação, designadas por pesquisas-ação colaborativas. Procuramos dar visibilidade aos processos empreendidos em tais pesquisas: Como se organizaram? Como os processos foram conduzidos? Que estratégias foram utilizadas pelos pesquisadores para estimular o professor a refletir e a investigar suas práticas? Como aconteceu o processo de mudança? No que os professores mudaram? Que problemas enfrentaram? Que procedimentos de análise e coleta de dados utilizaram? Na quarta sessão, traçamos nossas considerações finais. Nela procuramos relacionar as práticas empreendidas nas teses e dissertações estudadas (categorias empíricas: focos das pesquisas; espaço de concretização das pesquisas; organização processual das pesquisas; repercussão do processo; problemas enfrentados; e recursos metodológicos utilizados) e as teorias sobre pesquisa-ação. / The main object of this research aimed for giving visibility to the Brazilian production in action-research / action-inquiry, focusing overall on collaborative action-research. These research\'s conceptions stimulates the approach among teachers and researchers, by collaborating on investigative proceedings developed with, for e by teachers on school practices. In most cases, those researches were developed in schools. This study was developed in four sections: The first one is formed by a bibliographic study that aimed to indicate the theoreticians that have influenced this modality of research in Brazil. In order to achieve that some authors were taken: Saul, Freire, Thiollent, Barbier, Costa, André, Nóvoa, Geraldi, Fiorentini, Pereira, Stenhouse, Elliott, Carr, Kemmis and Zeichner. On the second part we have mapped dissertations and thesis on this kind of action-research, produced in Post Graduation Programs of Education in Brazil, between 1966-2002, presenting them in categories and subcategories investigated. The third one is formed by a qualitative documental study about a sample of actionresearches, designed by collaborative action-researches. It aimed to give visibility to process undertaken in those researches. How did they get organized? How the process were lead? Which strategies were used by the researches to stimulate teachers to reflect and investigate their practices? How happened the changing process? How have the teachers changed? What kind of problems they faced? Which proceedings of analysis and collecting of data did they use? On the fourth section, supported by the first and third parts, we related the practices undertaken in thesis and dissertations studied (empirical categories: researches\'s focus; space of materialization of the researches; procedural organization of the researches; repercussion of the process; problems faced and; methodological resources used) and the theories about action-research.
