Bases del coaching en la práctica docente: su posible aplicación en una clase de ELE de la Enseñanza Básica portuguesa

El presente informe tiene como propósito definir las bases esenciales del coaching y su posible adecuación al campo educativo, en una época en la que el alumnado parece un poco «desconectado» de la Escuela, no entendiendo a priori su importancia para su propio crecimiento personal y enriquecimiento profesional en el futuro. En el primer capítulo, empezaremos por la definición del concepto de coaching, su origen y principios fundamentales. En el segundo, el foco se centrará en la importancia de la aplicación de las bases del coaching en el proceso enseñanza-aprendizaje, el papel fundamental del profesor coach y sus competencias. En el tercero capítulo se dará cuenta de algunas herramientas internas (asociadas a la propia capacidad del profesor coach) y externas (aquellas que puede utilizar el docente al echar mano de recursos externos a él mismo) importantes en un proceso de coaching. En el cuarto capítulo, se procederá a la experiencia práctica de la metodología en clase, mencionando algunas limitaciones a su adaptación a la realidad, aún en este capítulo se pondrá en destaque la importancia de generar empatía desde las primeras clases; por último, se trazará la experiencia en una clase ELE (la que fue objeto de estudio en la Práctica de la Enseñanza Supervisionada) de acuerdo con el Modelo Grow, la técnica más frecuente en coaching, describiendo el perfil de la reality y el plan de acción a llevar a la práctica a lo largo del curso según los objetivos planteados, culminando en la análisis de los resultados obtenidos y su evaluación con respecto a la efectiva prosecución de la metodología aplicada. Al final, se procederá a una reflexión generalizada sobre el coaching en la educación y sus supuestos beneficios, no solo en el espacio restricto del aula, sino en el espacio más alargado del Colegio, en una perspectiva de crear alumnos más motivados y responsables, involucrados en «aprender a aprender», «aprender a hacer», «aprender a vivir» y «aprender a ser» - aspectos fundamentales en la creación de una Escuela de futuro.

On and off air: an ethnographic exploration of minority radio in Portugal

Taking a Media Anthropology’s approach to dynamics of mediated selfrepresentation in migratory contexts, this thesis starts by mapping radio initiatives produced by, for and/or with migrants in Portugal. To further explore dynamics of support of initial settlement in the country, community-making, cultural reproduction, and transnational connectivity - found both in the mapping stage and the minority media literature (e.g. Kosnick, 2007; Rigoni & Saitta, 2012; Silverstone & Georgiou, 2005) - a case study was selected: the station awarded with the first bilingual license in Portugal. The station in question caters largely to the British population presenting themselves as “expats” and residing in the Algarve. The ethnographic strategy to research it consisted of “following the radio” (Marcus, 1995) beyond the station and into the events and establishments it announces on air, so as to relate production and consumption realms. The leading research question asks how does locally produced radio play into “expats” processes of management of cultural identity – and what are the specificities of its role? Drawing on conceptualizations of lifestyle migration (Benson & O’Reilly, 2009), production of locality (Appadurai 1996) and the public sphere (Butsch, 2007; Calhoun & et al, 1992; Dahlgren, 2006), this thesis contributes to valuing radio as a productive gateway to research migrants’ construction of belonging, to inscribe a counterpoint in the field of minority media, and to debate conceptualizations of migratory categories and flows. Specifically, this thesis argues that the station fulfills similar roles to other minority radio initiatives but in ways that are specific to the population being catered to. Namely, unlike other minority stations, radio facilitates the process of transitioning between categories along on a continuum linking tourists and migrants. It also reflects and participates in strategies of reterritorialization that rest on functional and partial modes of incorporation. While contributing to sustain a translocality (Appadurai, 1996) it indexes and fosters a stance of connection that is symbolically and materially connected to the UK and other “neighborhoods” but is, simultaneously, oriented to engaging with the Algarve as “home”. Yet, besides reifying a British cultural identity, radio’s oral, repetitive and ephemeral discourse particularly trivializes the reproduction of an ambivalent stance of connection with place that is shared by other “expats”. This dynamic is related to migratory projects driven by social imaginaries fostered by international media that stimulate the search for idealized ways of living, which the radio associates with the Algarve. While recurrently localizing and validating the narrative projecting an idealized “good life”, radio amplifies dynamics among migrants that seem to reaffirm the migratory move as a good choice.

Medium access control design for distributed opportunistic radio networks

Existing wireless networks are characterized by a fixed spectrum assignment policy. However, the scarcity of available spectrum and its inefficient usage demands for a new communication paradigm to exploit the existing spectrum opportunistically. Future Cognitive Radio (CR) devices should be able to sense unoccupied spectrum and will allow the deployment of real opportunistic networks. Still, traditional Physical (PHY) and Medium Access Control (MAC) protocols are not suitable for this new type of networks because they are optimized to operate over fixed assigned frequency bands. Therefore, novel PHY-MAC cross-layer protocols should be developed to cope with the specific features of opportunistic networks. This thesis is mainly focused on the design and evaluation of MAC protocols for Decentralized Cognitive Radio Networks (DCRNs). It starts with a characterization of the spectrum sensing framework based on the Energy-Based Sensing (EBS) technique considering multiple scenarios. Then, guided by the sensing results obtained by the aforementioned technique, we present two novel decentralized CR MAC schemes: the first one designed to operate in single-channel scenarios and the second one to be used in multichannel scenarios. Analytical models for the network goodput, packet service time and individual transmission probability are derived and used to compute the performance of both protocols. Simulation results assess the accuracy of the analytical models as well as the benefits of the proposed CR MAC schemes.
