Dermatúnel: Modelo de ambiente interativo de aprendizagem em dermatologia

The Interactive Learning Environment (ILE) is an educational model that integrates features of 3D computer graphics and contextualization, in order to transmit a quantum of knowledge (islands of knowledge), in a precise and agile way, to people who do not know the subject. It is a model that uses multimedia resources supported by a contextualized environment to motivate the participants in the retention of knowledge. In this first release, eight relevant subjects in dermatology were addressed and implemented in the 62nd Brazilian Congress of Dermatology. The model was called Dermatúnel. In a period of four days, 3295 people visited it. The results showed that the participants were highly satisfied. The model has a great potential as an educational tool for medical training and guidance to the general public with the purpose of disease prevention.

A proposal for enhancing the motivation in students of computer programming

Computer programming is known to be one of the most difficult courses for students in the first year of engineering. They are faced with the challenge of abstract thinking and gaining programming skills for the first time. These skills are acquired by continuous practicing from the start of the course. In order to enhance the motivation and dynamism of the learning and assessment processes, we have proposed the use of three educational resources namely screencasts, self-assessment questionnaires and automated grading of assignments. These resources have been made available in Moodle which is a Learning Management System widely used in education environments and adopted by the Telecommunications Engineering School at the Universidad Politécnica de Madrid (UPM). Both teachers and students can enhance the learning and assessment processes through the use of new educational activities such as self-assessment questionnaires and automated grading of assignments. On the other hand, multimedia resources such as screencasts can guide students in complex topics. The resources proposed allow teachers to improve their tutorial actions since they provide immediate feedback and comments to students without the enormous effort of manual correction and evaluation by teachers specially taking into account the large number of students enrolled in the course. In this paper we present the case study where three proposed educational resources were applied. We describe the special features of the course and explain why the use of these resources can both enhance the students? motivation and improve the teaching and learning processes. Our research work was carried out on students attending the "Computer programming" course offered in the first year of a Telecommunications Engineering degree at UPM. This course is mandatory and has more than 450 enrolled students. Our purpose is to encourage the motivation and dynamism of the learning and assessment processes.

Perceptions of Usability and Usefulness in Digital Libraries

This paper provides an overview of a case study research that investigated the use of Digital Library (DL) resources in two undergraduate classes and explored faculty and students’ perceptions of educational digital libraries. This study found that students and faculty use academic DLs primarily for textual resources, but turn to the open Web for visual and multimedia resources. The study participants did not perceive academic libraries as a useful source of digital images and used search engines when searching for visual resources. The limited use of digital library resources for teaching and learning is associated with perceptions of usefulness and ease of use, especially if considered in a broader information landscape, in conjunction with other library information systems, and in the context of Web resources. The limited use of digital libraries is related to the following perceptions: 1) Library systems are not viewed as user-friendly, which in turn discourages potential users from trying DLs provided by academic libraries; 2) Academic libraries are perceived as places of primarily textual resources; perceptions of usefulness, especially in regard to relevance of content, coverage, and currency, seem to have a negative effect on user intention to use DLs, especially when searching for visual materials.

Narrativa transmedia y percepción cognitiva en El Ministerio del Tiempo (TVE)

Introducción: En el presente trabajo se analiza la serie de ficción de TVE El Ministerio del Tiempo con el objetivo de determinar si el mayor conocimiento de la serie de ficción, el uso de las redes sociales y los recursos multimedia modifican la percepción del espectador. Metodología: Se procedió a realizar un trabajo de campo compuesto por 124 observadores a los que se les ha aplicado la escala EDI (Escala de identificación con los personajes). Resultados: Se concluye que un mayor conocimiento de la serie y el uso de las propuestas transmedia produce una mayor identificación con los personajes de ficción, aunque solo en los ítems que definen una mayor carga emocional o sentimental. Discusión: Lo anterior evidencia sin embargo, que no es aplicable a la evaluación cognitiva de aquellos espectadores más fieles a la serie. Conclusiones: Con los resultados obtenidos es posible afirmar que los contenidos transmedia se suceden en la percepción de los observadores desde lo racional a lo emocional. El conocimiento previo de la serie y el uso de las propuestas transmedia alarga la relación con lo visionado más allá del disfrute ocasional.

e-Astro: O e-learning aplicado ao ensino da astronomia: Planetas telúricos

A investigação em didáctica das ciências tem mostrado que a generalidade dos alunos manifesta cada vez menos interesse para aprender ciências. No entanto, o incremento da importância de temas científicos no nosso dia-a-dia, exige dos indivíduos um conhecimento científico cada vez mais aprofundado. O estudo da Astronomia permite abordar e interligar os conteúdos de tisica mais facilmente, tomando possível a aproximação do conhecimento científico ao conhecimento do quotidiano, mostrando a estreita ligação entre a Física, a Sociedade e a Tecnologia. O processo de ensino-aprendizagem encontra-se em mudança devido à integração das T.I.C. Através da internet e tirando partido da multimédia é possível desenvolver uma formação científica adequada que contribua para o despertar da curiosidade e do interesse dos alunos pela Ciência. Tendo em conta os pressupostos anteriores pretende-se, com este estudo, desenvolver uma plataforma de e-learning e recursos multimédia que satisfaçam estes requisitos. ABSTRACT; The investigation in didactics of sciences has been showing that the generality of students show less and less interest to learn sciences. However, the increment of the importance of scientific themes in our day-to-day life, demands from the individuals an increasingly deeper scientific knowledge. The study of Astronomy allows to approach and to interconnect physics subjects more easily, making possible the approach of scientific knowledge to the knowledge of everyday life, showing the narrow connection among Physics, Society and Technology. The teaching-learning process is in change duet the integration of the I.C.T. Through the internet and taking advantage of multimedia it is possible to develop an appropriate scientific formation that contributes to the awakening of curiosity and of the student's interest for Science. Having in mind the previous presuppositions is intended, with this study, to develop an e-learning platform and multimedia resources that satisfy these requirements.

Babxel: búsqueda multilingüe

La Web 2.0 ha tenido un enorme éxito gracias a la posibilidad de una interacción dinámica por parte del usuario, ya no sólo a la hora de participar en elementos colaborativos, como puedan ser los foros, sino en compartir/añadir contenido a la Web. Dos ejemplos claros de este paradigma son YouTube y Flickr. El primero hospeda la mayor parte de los vídeos que podemos encontrar en Internet, y el segundo ha creado la mayor comunidad de fotógrafos existente en la red. Ambos servicios funcionan de una forma similar, el usuario es el que aporta contenidos junto a una información asociada al mismo. Al ser comunidades internacionales, la información añadida por el usuario se realiza en diversos idiomas, por lo que la búsqueda de recursos multimedia en estos sitios es dependiente del idioma de la consulta. En este artículo, presentamos Babxel, un sistema de recuperación de información multimedia y multilingüe, nacido como proyecto de fin de carrera de Ingeniería Informática, como extensión y mejora de FlickrBabel. Babxel aprovecha la capacidad de traducción multilingüe automática para generar más resultados de búsqueda relacionado con la consulta del usuario, resultados que se obtienen de las plataformas mencionadas anteriormente.

Code offloading on real-time multimedia systems: a framework for handling code mobility and code offloading in a QoS aware environment

Actualmente, os smartphones e outros dispositivos móveis têm vindo a ser dotados com cada vez maior poder computacional, sendo capazes de executar um vasto conjunto de aplicações desde simples programas de para tirar notas até sofisticados programas de navegação. Porém, mesmo com a evolução do seu hardware, os actuais dispositivos móveis ainda não possuem as mesmas capacidades que os computadores de mesa ou portáteis. Uma possível solução para este problema é distribuir a aplicação, executando partes dela no dispositivo local e o resto em outros dispositivos ligados à rede. Adicionalmente, alguns tipos de aplicações como aplicações multimédia, jogos electrónicos ou aplicações de ambiente imersivos possuem requisitos em termos de Qualidade de Serviço, particularmente de tempo real. Ao longo desta tese é proposto um sistema de execução de código remota para sistemas distribuídos com restrições de tempo-real. A arquitectura proposta adapta-se a sistemas que necessitem de executar periodicamente e em paralelo mesmo conjunto de funções com garantias de tempo real, mesmo desconhecendo os tempos de execução das referidas funções. A plataforma proposta foi desenvolvida para sistemas móveis capazes de executar o Sistema Operativo Android.

Cooperative Transmission and Radio Resources Management for Wireless Networks

Report for the scientific sojourn at the Multimedia Communications Laboratory, University of Texas at Dallas, USA, from September to December 2005. The cooperative transmission has been analyzed taking a broadcast relay channel which assumes a scenario with one source and multiple destinations. Moreover, in order to improve the performance in terms of mutual information, it has been considered that for each destination there is another nearby terminal (called relay) which will help to improve the performance of the destination. This scheme combines different types of channels considered in the information theory, such as the relay channel, broadcast channel and interference channel (if the relays transmit information intended only to its associated destination). In this work, the author has studied the optimal way to encode the signals for the different users, known as capacity region (i.e. related to radio resources management ), of the broadcast relay channel.
