Seu objetivo é investigar as possibilidades e limites das trocas interacionais e comunicacionais que ocorrem nesses ambientes, considerando que são mediadas pela tecnologia. Tomamos como objeto empírico o grupo Direitos Urbanos | Recife (DU), abrigado no Facebook desde 2012, cujo propósito é discutir os problemas urbanos da cidade do Recife, estado de Pernambuco, Brasil. Contando com cerca de 30 mil participantes, a página da comunidade representa um campo institucional que dá suporte às ações off-line do movimento, que se caracterizam pela ocupação de espaços públicos no sentido de reivindicar o direito à cidade. O Facebook é utilizado pelo movimento não apenas para discussões, mas também para informar, articular e mobilizar, seguindo uma receita adotada por inúmeros outros movimentos que têm eclodido ao redor do mundo, tais como o Ocupe Wall Street. Analisando as trocas interacionais e comunicacionais no ambiente do DU, e os efeitos positivos e negativos da tecnologia sobre esse ambiente, buscamos identificar a estrutura das redes sociais e os atores mais centrais, formatos, conteúdos e fluxo das publicações, como ocorre a conversação em si e a ação dos moderadores para a manutenção da ordem e dos discursos do grupo. Constatamos, entre outras coisas, que o DU abriga redes pouco vivas e muito fragmentadas, com poucos atores bem conectados, baixa interação e poucas relações de amizade. Além disso, a comunicação nesse espaço está sujeita a ruídos e ambiguidades e, ainda assim, consegue abrir brechas para a ação comunicativa, gerando laços de apoio e solidariedade. / This is a thesis about online communities sheltered in social network sites. It aims investigate the possibilities and limits of interactional and communicational exchanges that occur in these environments considering that are mediated by technology. We took as empirical object the Direitos Urbanos | Recife group, sheltered in Facebook since 2012, whose purpose is to discuss urban problems of the city of Recife, state of Pernambuco, Brazil. Bringing together about 30,000 participants, the community page is an institutional field that supports the offline actions of the movement which is characterized by occupying public spaces in order to claim the right to the city. Facebook is used by the movement not only for discussion but also to inform, coordinate, and mobilize, following a recipe adopted by numerous other movements that have hatched around the world such Occupy Wall Street. Analyzing the interactional and communicational exchanges in DU environment we seek to identify the structure of social networks and the most central actors, formats, content, and flow of publications, as is the conversation itself and the action of moderators to maintain order and group discourses. We find among other things that DU has little living and fragmented networks, with few well-connected actors, low interaction and few friendships. In addition communication in this space is subject to noise and ambiguities and still can open loopholes for communicative actions, generating support and solidarity ties.

À la lumière des connaissances théoriques actuelles, cette recherche-action est centrée sur un projet dans lequel les apprenants à l'Université Nationale –Palmira ont la possibilité d'améliorer leur interlangue en anglais. Notre hypothèse principale est la suivante : en adoptant l'approche par tâches, les activités d‘enseignement / apprentissage seraient plus efficaces dans le programme de formation en L2. En fait, l‘acquisition des connaissances pour l‘interaction langagière orale et la compréhension des textes scientifiques dans les cours de la L2 aidera ces apprenants à développer des compétences pour interagir dans des situations de la vie réelle, mais aussi à acquérir les "savoirs" et les techniques pour extraire les informations contenues dans les textes écrits scientifiques. Cette hypothèse a été validée par la réalisation d'une expérience d‘enseignement / apprentissage. D‘autres hypothèses secondaires ont cherché à obtenir des informations sur les besoins, attentes et attitudes aussi bien des apprenants que des enseignants de la formation institutionnelle en anglais. Nous souhaitons que cet apport permette à notre université de s‘engager dans un processus d‘innovations pédagogiques où les apprenants adoptent une posture plus responsable concernant l‘apprentissage d‘une L2. / In the light of current theoretical knowledge, this action-research focuses on a project in which learners at the National University –Palmira have the opportunity of improving their inter-language in English. Our main hypothesis is that by adopting the task-based approach, L2 learning would be more efficient. It is inferred based-learning activities will help them to develop ways of obtaining knowledge and strategies to interact in real-life situations, and techniques to extract information from scientific written texts. This hypothesis has been validated through the realization of teaching / learning practices. Some secondary hypotheses to establish learners‘ and teachers‘ needs, expectations, goals and attitudes of formal training in English were also verified in this action-research. We hope this contribution may lead our university to adopt pedagogical innovative practices in which learners feel more concerned and involved in acquiring a second language.
