Digital Figurations : The Human Figure as Cinematic Concept

Fredholm, Tilde January 2016 (has links)
Mainstream cinema is to an ever-increasing degree deploying digital imaging technologies to work with the human form; expanding on it, morphing its features, or providing new ways of presenting it. This has prompted theories of simulation and virtualisation to explore the cultural and aesthetic implications, anxieties, and possibilities of a loss of the ‘real’ – in turn often defined in terms of the photographic trace. This thesis wants to provide another perspective. Following instead some recent imperatives in art-theory, this study looks to introduce and expand on the notion of the human figure, as pertaining to processes of figuration rather than (only) representation. The notion of the figure and figuration have an extended history in the fields of hermeneutics, aesthetics, and philosophy, through which they have come to stand for particular theories and methodologies with regards to images and their communication of meaning. This objective of this study is to appropriate these for film-theory, culminating in two case-studies to demonstrate how formal parameters present and organise ideas of the body and the human. The aim is to develop a material approach to contemporary digital practices, where bodies have not ceased to matter but are framed in new ways by new technologies.

As transformações da escuta a partir da utilização das mídias portáteis / Changings of the listening process by the use of portable media

Santos, Otavio Luis Silva 08 August 2014 (has links)
Com o passar dos anos, o hábito da escuta musical passou por diversas transformações, comumente relacionadas a tendências sociais e inovações tecnológicas. No início do século XX, a relação homem-máquina-escuta se elevou a um novo patamar. No início do século XXI, o predomínio das mídias portáteis (aqui delimitadas a iPods, tablets e smartphones) promove novas transformações na prática da escuta musical, gerando consequências musicais e sociais consideráveis. Partindo do Walkman, um dos maiores ícones da portabilidade do século passado, esse trabalho analisa a sucessão das principais mídias e formatos - com seus respectivos impactos culturais - até alcançar a década de 2010, dominada pelo formato MP3 e já fundada em uma peculiar prática de escuta musical. Através de extensa pesquisa bibliográfica e audiovisual, este trabalho se dispõe a refletir sobre as principais transformações músico-sociais originadas a partir da utilização massiva das mídias portáteis (como meio predominante de prática da escuta musical urbana), tornando mais visível a relevância de estudos aprofundados na área / Throughout the years, musical listening habits have suffered many changings, usually related to social tendencies and technological improvements. In the beginning of the 20th century, the man - machine- listening relation achieved a new level. During the first decades of the 21th century, the ubiquity of portable media (defined in this work as iPods, tablets and smartphones) promotes new alterations in the listening habits, therefore social and musical impacts. Beginning from the Walkman, one of last century\'s most acclaimed icons of portability, this work analyses the sequence of the following main devices and formats - each one with its particular cultural impacts - until reaching the 2010s, a decade dominated by MP3 and based on a unique musical listening experience. This work intends to reflect, through extensive research and bibliographical discussion, the main musical and social reorganization originated by the massive use of these devices as the urban leading musical listening vehicle, increasing the visibility and the relevance of more detailed researches in this area.

No. of bitstreams: 1 Valeria Bussola Martins.pdf: 1953663 bytes, checksum: 49a811a43fbf4e3e9195d11c45f33c58 (MD5) Previous issue date: 2011-05-13 / The importance of reading in the education of critical and informed citizens has always been unquestionable. Reading normally offers autonomy for individuals so that they can live well in society. Narrowing this reality down to the educational field, if in the past school was able to make most students read literary works without much trouble, nowadays it sees its students connected as if to an umbilical cord to electronic games and the internet, elements that have been deviating pupils from reading practices. Games and the virtual world have actually become more attractive than books. However, these instruments which are primarily used for entertainment do not have to be excluded from the school ambit. This research has been idealized based on these daily queries. It intends to reflect upon the pedagogical practice in the Portuguese language teaching in the Brazilian middle school and junior high and to search alternatives to promote the taste for reading. The aim of this study is to ponder upon the role of Portuguese teachers in enabling students to become effective readers and to show pedagogical practices which, based on digital technology, have proved to be efficient during reading and writing classes and which resulted in new forms of reading comprehension assessment. Finally, the research considers the need for rethinking Portuguese teachers' education and the great importance of continuing professional development. / A importância da leitura na formação de cidadãos críticos e reflexivos sempre foi inquestionável. Normalmente, a leitura oferece autonomia a qualquer indivíduo para que ele viva em sociedade. Restringindo tal realidade ao plano educacional, se no passado a escola conseguiu levar significativa parcela de seus alunos a lerem várias obras literárias sem grandes problemas, na atualidade, porém, veem-se discentes ligados, quase que por um cordão umbilical, a jogos eletrônicos e à internet, elementos que desviaram da leitura a atenção de parte desses jovens. Os jogos e o mundo virtual, portanto, tornaram-se mais atraentes e mais procurados do que os livros. Entretanto, esses instrumentos que, em primeira instância, servem como passatempo e diversão não precisam ser excluídos do ambiente escolar. A partir desses questionamentos cotidianos, é que este trabalho foi idealizado. Trata-se, portanto, de um instrumento de reflexão sobre a prática pedagógica na área de Língua Portuguesa no Ensino Fundamental II, que busca alternativa para incentivar o gosto dos alunos pela leitura. O objetivo desta pesquisa é refletir acerca do papel do professor de Língua Portuguesa do Ensino Fundamental II na formação de leitores efetivos e expor práticas pedagógicas, calcadas em mídias digitais, que se demonstraram eficazes durante as aulas de leitura e produção de texto e que resultaram em novas formas de avaliação do processo de leitura de livros paradidáticos. Por fim, considera-se a necessidade de se repensar a formação dos docentes de Língua Portuguesa e a importância da constante atualização dos professores em pleno exercício.

Made available in DSpace on 2016-04-29T14:22:49Z (GMT). No. of bitstreams: 1 William Bezerra.pdf: 1607820 bytes, checksum: 4afe5e46e8660114b8394ab613a32637 (MD5) Previous issue date: 2010-10-05 / This work is intended to analyze databases and its influence among digital culture. We will show that database usage and database logic are becoming more common than ever in this culture and it is implicit to users. Once we realize this predominance, we ask if database usage can affect the way we understand the world, making this interaction more binary, dichotomous, ordered and more objective, like database logics would do with its formal structures of cataloging and data availability. To answer this question we will analyze database designs, from data modeling to creation and use (Date). Thus, we show how the ideas of a project, initially informal, become formal though the project designer's choices and binary data structure rules, ending up in a product released for use (Setzer). After that, we will see how all of this formal mode including main database features - and digital technology features - come from the military environment of power and control (Gere), also based on quantifier (Crosby) and visual models (Crary) transferred to digital model. Finally, we wrote a case study based on what we have discussed, mainly focused on database logic (Manovich), confirming its presence on all ways, even storing untouchable things, like feelings / Neste trabalho, analisaremos os bancos de dados e suas influências dentro da cultura digital. Evidenciaremos que a utilização de bases de dados e de aplicativos que seguem a sua lógica é cada vez mais predominante na cultura digital, mesmo que isso geralmente não seja percebido, por não haver um contato direto entre os usuários e os dados armazenados. Dada esta predominância, questionaremos se, ao utilizarmos os bancos de dados, pode ocorrer alguma interferência na nossa apreensão e percepção de mundo, de forma que elas sejam mais binárias, dicotômicas, ordenadas e objetivas, ou seja, em conformidade com a lógica dos bancos de dados e suas estruturas formais de catalogação e disponibilização de dados. Para averiguar esses questionamentos, elaboraremos uma análise crítica sobre a concepção dos bancos de dados, desde os modelos de dados até sua implementação e utilização (Date). Com isso, demonstraremos como as idéias para o projeto, a princípio informais, formalizam-se mediante as escolhas dos seus criadores e as imposições e regras das estruturas de dados binárias, finalmente culminando em um produto acabado que é, enfim, liberado para utilização (Setzer). Em seguida, veremos como toda esta formalização e as principais funcionalidades dos bancos de dados e das tecnologias digitais como um todo , advêm de pressupostos definidos em sua fase de desenvolvimento inicial, dentro de um contexto militar de poder e controle (Gere), também baseados em alicerces quantificadores (Crosby) e visuais (Crary), herdados e repassados ao digital. Por último, realizaremos um estudo de um caso prático fundamentado nos pressupostos discutidos no transcorrer de todo o trabalho e focado principalmente na lógica dos bancos de dados (Manovich), confirmando sua presença em todas as circunstâncias, sendo utilizada inclusive para catalogar coisas, a princípio fluídas, como por exemplo, os sentimentos

No. of bitstreams: 1 Gisele Vieira de Oliveira Castro.pdf: 1719512 bytes, checksum: 7d2a62f9f813e84d88ed82dd3a9fcc59 (MD5) Previous issue date: 2012-05-18 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Corporate distance education has been growing considerable in the last years. This growth is due to, between many reasons, the low price compared with presential training, the possibility to reuse the same content for thousand people without additional expense, the decrease of time spent with training and information management. Within this context, we may ask: are numbers enough to ensure we are in the right way with regard to corporate distance education in the Digital Era? To answer this question, we took as basis Phenomenology, theory whereby perception is our first cognitive instance, our first contact with the external world. Thereafter, we interspersed the concept of perception, technique and digital technology, with support of the following authors: Maturana, Varela, Flusser, Pierre Lèvy, André Parente, Basbaum, Heidegger, and others. Then, we discussed, from Bondía s perspective, education as legitimization of practices and knowledge instituted by the technique, considered as reality and truth, and this discourse pervades the corporate distance education contents and enhances the model s digital though, of maximum efficiency and lower noise. Finally, we propose the resumption of experience as starting point in corporate distance education and some suggestions for how to do it in current context, considering experience as multiple, opened, and, therefore incalculable / O mercado de educação à distância corporativa tem crescido consideravelmente nos últimos anos. Tal crescimento se deve, dentre diversos fatores, ao baixo custo, se comparado com treinamentos presenciais, à possibilidade de usar o mesmo treinamento para milhares de pessoas sem necessidade de investimento adicional, à economia de tempo e à possibilidade de gestão da informação. Diante desse contexto, cabe a pergunta: será que os números são suficientes para se afirmar que estamos no caminho certo no que tange à educação corporativa na Era digital? Para responder a essa pergunta, tomamos como base a Fenomenologia, linha de pensamento segundo a qual a percepção é nossa primeira instância cognitiva, nossa primeira comunicação com o mundo. A partir de então, interpolamos percepção, técnica e tecnologia digital com o suporte de autores, como Maturana, Varela, Flusser, Pierre Lèvy, André Parente, Basbaum, Heidegger, entre outros. Em seguida, discutimos, sob a ótica de Bondía, a educação enquanto legitimadora de um fazer instaurado pela técnica, tido então como realidade e como verdade, discurso esse que permeia os cursos de educação à distância corporativos e que reforça a lógica do modelo digital, de máxima eficiência e menor ruído. Ao final, propomos a retomada da experiência como ponto de partida na educação à distância corporativa e algumas sugestões de como é possível fazê-la no contexto atual, considerando que a experiência é múltipla, aberta e, portanto, incalculável

The Negative Effects Of Technology-driven Design On User-product Interaction And Product Usability

Gultekin, Pelin 01 May 2004 (has links) (PDF)
In the last decades, the rapid change and prevalent use of technology are concerning, as they induced effects which mainly altered various encompassing contexts like consumer market dynamics and product development processes. Evidently, these transformations also affect the way users interact with products. It is observed that, technological novelties are applied in the competitive market as a tool for product differentiation. In addition, the rapid development of these technologies is a dominating factor on shortening product lifecycles. Resulting from these two factors, implementing latest technologies in new products is interpreted by producers as an absolute way of achieving market success. Consequently, most of the products in everyday life are designed with a primary aim to implement latest technological advances, without appropriate consideration of user requirements and characteristics. The phenomenon has negative consequences on product usability. This study basically examines the usability problems that are related with digital technology impelementations in consumer products. The evaluations are based on the contexts such as: changes in contemporary market conditions with the effects of the recent technological developments, technology-driven approaches in product development processes and the transformative consequences of digital technology applications on user-product interaction. Literature surveys are employed as method. Finally, interaction characteristics of digital products and the contexts in which they are used are evaluated and it is argued that, the usability problems are due to the deficiency in evaluations of user characteristics and requirements during the product development processes, in general terms.

Na era digital, surgem ambientes virtuais que propiciam interações sociais, reais e significativas, através do uso da língua, que devem ser trazidas para os espaços escolares, ainda que haja resistência e/ou dificuldades de ordem pedagógico/formacional ou ausência de recursos tecnológicos suficientes para sua aplicabilidade. Trata-se de um estudo de cunho qualitativo, no qual realizei pesquisa bibliográfica e de campo, com dois sujeitos distintos: alunos de uma turma de Ensino Médio e uma professora do mesmo segmento. Para tanto, trago à discussão conceitos relevantes como alfabetização, letramento, multiletramentos e letramento digital, a partir de autores como Soares (2002; 2009), Beltrão (1986), Rojo (2015; 2013; 2012; 2011; 2009), Ribeiro (2009; 2010), Xavier (2008; 2002), Silva (2008, 2017), Batista (1997), Geraldi (2012), Coscarelli (2007), Marcuschi (2010); Lemos (2003), Lévy (2010), dentre outros nomes relevantes. Ficou perceptível que os alunos fazem uso das tecnologias digitais cotidianamente e buscam conhecimentos nos meios digitais, sobretudo acerca de conteúdos trazidos para a sala de aula que despertam alguma curiosidade/desejo de aprofundamento de informações, de forma complementar, representando, de certo modo, sua autonomia e independência. A Professora, sujeito da pesquisa, apresentou proficiência/fluência digital suficiente para ministrar aulas de Língua Portuguesa voltadas ao uso de tecnologias digitais, entretanto, demonstrou insatisfação em relação à estrutura e aos parcos recursos materiais disponíveis na instituição. Suas aulas ainda são voltadas principalmente para a realização de conteúdos gramaticais, priorizando o ensino de conteúdos voltados à compreensão de tópicos da gramática normativa. Entretanto, procura diversificar as atividades em sala de aula, dando sugestões de pesquisas nos meios digitais e exibição de vídeos temáticos, sempre que possível. Concluo, portanto, que as aulas de Língua Portuguesa na era digital estão no caminho certo, com possíveis interações e articulações, porém, ainda de forma lenta e incipiente. É preciso mais investimentos por parte do Poder Público, com investimentos em recursos tecnológicos, acesso à internet de qualidade e cursos de formação continuada que possibilitem discussão e elaboração de atividades práticas que incentivem o professor de Língua Portuguesa a pensar frequentemente em atividades que direcionem para o uso concreto e interacional da língua. / ABSTRACT This study deals with questions that guide the teaching and learning of the Portuguese language in the digital age and the possible interactions and articulations that may follow. In the digital age, virtual environments arise that provide real and meaningful social interactions through the use of language, which must be brought to school, even if there is resistance and / or pedagogical / formational difficulties or lack of sufficient technological resources for its applicability. This is a qualitative study, in which I carried out bibliographic and field research, with two distinct subjects: students from a high school class and a teacher from the same segment. In order to do so, I bring to the discussion relevant concepts such as literacy, literacy, multiletrations and digital literacy, from authors such as Soares (2002; 2009), Beltrão (1986), Red (2015; 2013; 2009), Xavier (2008, 2002), Silva (2008, 2017), Batista (1997), Geraldi (2012), Coscarelli (2007), Marcuschi (2010); Lemos (2003), Lévy (2010), among other relevant names.It became clear that students use digital technologies on a daily basis and seek knowledge in digital media, especially about content brought to the classroom that arouse some curiosity / desire to deepen information, in a complementary way, representing, in a way, its autonomy and independence. The Teacher, subject of the research, presented sufficient digital proficiency / fluency to teach Portuguese Language classes focused on the use of digital technologies, however, showed dissatisfaction with the structure and the meager material resources available at the institution. Her classes are still mainly focused on the accomplishment of grammatical contents, prioritizing the teaching of contents aimed at understanding topics of normative grammar. However, it seeks to diversify activities in the classroom, giving suggestions on digital media searches and thematic videos, wherever possible. I conclude, therefore, that Portuguese Language classes in the digital age are on the right path, with possible interactions and articulations, but still slowly and incipiently. It is necessary to invest more in the Public Power, with investments in technological resources, access to quality internet and continuous training courses that allow discussion and elaboration of practical activities that encourage the Portuguese Language teacher to think often in activities that direct to the concrete and interactive use of the language.

L’implication des technologies de l'information et de la communication dans le développement de l’autoformation des enseignants d'école élémentaire issus de la masterisation : origines, représentations et enjeux / The involvement of Information and Communication Technologies in the development of the self-training of primary school teachers who have originated from masterisation : origins, representations and stakes

Lehéricey, David 04 December 2014 (has links)
La recherche présentée s’intéresse à l’implication des Technologies de l’Information et de la Communication (TIC) dans le développement de l’autoformation des professeurs des écoles stagiaires. Elle s’inscrit dans un double contexte. D’une part, celui de la mise en place de la réforme de la formation initiale des enseignants – la masterisation –, ayant eu cours, en France, de 2010 à 2013. D’autre part, celui des problématiques contemporaines liées à la question des usages du numérique à des fins d’autoformation. Dans cette perspective, ce travail s’appuie sur les données d’entretiens individuels, réalisés auprès de professeurs des écoles stagiaires issus de la masterisation, afin d’explorer leur rapport au métier, au(x) savoir(s) et aux technologies de l’information et de la communication. Il vise à mieux comprendre ce que représente, pour eux, l’autoformation aux et par les TIC et à saisir ce que cela soulève d’enjeux, en termes de construction et de développement professionnel. Il en ressort qu’à la complexité de cette période tout à fait particulière d’entrée dans le métier, s’ajoute aujourd’hui pour les enseignants débutants, celle d’enseigner mais également de se former et de s’autoformer dans un « monde numérique ». Il semble que les potentialités qu’offrent les technologies ne font que renforcer l’importance fondamentale d’une formation initiale solide, passant avant tout par un renforcement des interactions humaines, par un accompagnement éclairé et éclairant des enseignants débutants, leur permettant de développer au plus tôt leurs compétences professionnelles et d’être à même de les faire évoluer tout au long de leur carrière. / The present research treats of the involvement of Information and Communication Technologies in the development of the self-training of to-be primary school teachers. The context in which this research settles is double. Firstly, that of the setting up of the teachers’ training reform – masterisation – which took place in France from 2010 to 2013. Secondly, that of the contemporary problems related to the use of digital technology for self-training. The following work is based on data which was gathered during individual interviews with primary school teacher trainees who originated from masterisation, in order to explore their views on the profession, on the knowledge as well as on Information and Communication Technologies. Its goal is the better understanding of what self-training via ITCs represents for them, and also to bring into light the stakes engendered, in terms of career building and development. What stands out from this, is that the complexity of this rather peculiar pre-teaching phase is doubled by that of teaching and of self-training in a “digital world”. It appears that the infinite possibilities which are offered by these technologies only strengthen the need for a very solid initial training. This implies the reinforcement of human interaction through an enlightened and enlightening guidance for beginning teachers, enabling them to develop all the sooner their professional competence and to continue to make them evolve all along their career.

Digital teknik som stöd i matematikundervisning: : När unga elever ska tolka och förstå ett matematiskt problem- / Digital technology support in the teaching of mathematics: : When young students are to interpret and understand a mathematical problem

Stålberg, Emmelie January 2018 (has links)
Syftet med denna systematiska litteraturstudie är att undersöka vilken typ av stöd digital teknik kan ge elever som ska förstå och tolka ett matematiskt problem. Att förstå och tolka matematiska problem inbegriper ofta förmågan att kunna läsa och förstå en text. Unga elever som är i början av sin läs- och skrivutveckling har ofta svårigheter med läsförståelsen. Digital teknik kan ge eleverna stöd vid tolkning och förståelse för ett matematiskt problem genom att mediera den kunskap som är absolut nödvändig för att kunna lösa problemet. De olika typerna av stöd som har identifierats används på olika sätt fast med samma syfte, att hjälpa elever att förstå ett matematiskt problem. Även om användandet av digital teknik har visat flera olika typer av effekter på elevers problemlösningsförmåga så går det att urskilja en positiv trend. Den digitala teknik som har studerats har till största del bidragit till positiva effekter och endast en studie har uttryckt en negativ effekt på elevers förmåga att lösa problem. / This systematic literature study aims to examine which types of support digital technology can offer students when they are presented to a mathematical problem. To fully understand a mathematical problem, it often requires the ability to read texts. Young students in the beginning of their reading and writing development often shows a lack of reading comprehension. Digital technology can offer students support while solving mathematical problems by mediate the most essential parts of the problem. The various kinds of support that have been identified are all used in separate ways but with the same purpose; helping students to understand a mathematical problem. Even if the use of digital technology has shown several types of effects, on students ability to solve mathematical problems, a positive trend can be distinguished. Only one study has shown a negative effect on students ability to solve mathematical problems.

As perspectivas teóricas denominadas experimentação-com-tecnologias e investigação matemática foram utilizadas para elaborar e analisar as atividades criadas. Tais perspectivas também embasaram a análise das discussões ocorridas. Do ponto de vista metodológico, a pesquisa possui um caráter qualitativo pois visa compreensões específicas acerca do fenômeno investigado. Nesse sentido, foram registradas em vídeo reuniões nas quais um grupo de pesquisadores dialogou sobre a elaboração e aprimoramento de diferentes versões de cada tarefa, visando sua utilização em um curso de extensão universitária destinado a professores e alunos de licenciatura em Matemática. As tarefas eram baseadas na Geometria Espacial. Parte das discussões ocorreu também por meio de postagens e comentários em um grupo fechado do Facebook, no qual as versões das atividades eram inicialmente compartilhadas. As diferentes versões de cada atividade foram documentadas assim como os comentários de cada postagem. Este material foi analisado visando a compreensão do processo de aprimoramento do caráter investigativo e experimental de cada tarefa matemática elaborada. A análise foi dividida em três categorias, sendo elas: design e investigação, experimentação no processo de elaboração e visualização. Tal análise sugere que o processo de elaboração está sujeito a reflexões a respeito do público alvo e seu conhecimento a respeito do GeoGebra e também de Matemática. A participação do grupo de pesquisa GPIMEM no processo também se mostrou significativa para a concepção das tarefas. Repensar as atividades após e durante sua utilização didático-pedagógica também surge como parte fundamental deste processo, assim como mudanças recursivas de enunciado mediante as considerações levantadas colaborativamente. Esta pesquisa visou contribuir para os estudos que envolvem a Matemática ensinada em conjunto com recursos tecnológicos. Conhecer o processo de elaboração proporciona à comunidade da Educação Matemática perceber a gênese do desenvolvimento de materiais didáticos construídos colaborativamente, assim como a riqueza de ideias desenvolvidas em meio a este progresso. / The aim of this research was investigate how the process of elaboration of mathematical tasks using the computational software GeoGebra by researchers in Mathematics Education takes place. The theoretical perspectives called experimentation-and-technologies and mathematical investigation theories were used to elaborate and analyze the tasks created. Such perspectives also have brought the analysis of the discussions that took place. From the methodological point of view, the research has a qualitative character because it aims specific understanding of the investigated phenomenon. In this scenario, video meetings were recorded in which a group of researchers dialogged on the elaboration and improvement of different versions of each task, aiming at its use in a university extension course for teachers and students of licencatory in mathematics. The tasks presented are based on spatial geometry. Part of the discussions also occurred through posts and comments in a closed group of Facebook, in which the versions of the activities were initially shared. The different versions and the comments of each activity were documented. This material was analyzed aimed at understanding the process of improving the investigative and experimental character of each elaborate mathematical task. Moreover, the participation of the GPIMEM research group was important for the process of creation of the tasks. Rethinking the activities after their didactic-pedagogy use is also a fundamental part of these processes, such as recursive changes of statements through the considerations raised collaboratively. The analysis was divided into three categories, are they design and research, experimentation in the process of preparation and visualization. Such an analysis suggests that the process of preparation is subject to reflections regarding the target pubic and his knowledge about Geogebra and also of mathematics. Also the participation of the GPIMEM research group in the process was significant for the design of the tasks. Rethinking activities after their didactic-pedagogical use also arises as a key part of this process, as well as recursive changes in the statement of collaboratively. This research aimed to contribute to the studies involving Mathematics taught in conjunction with technological resources. Knowing the process of elaboration provides the Community of Mathematical Education to realize the genesis of the development of didactic materials constructed collaboratively, as well as the wealth of ideas developed in the midst of this progress. / CAPES: 130128/2017-1
