Propuestas de integración de las tecnologías de la información y comunicación para la mejora de las prácticas docentes

En el presente artículo abordamos la utilización de un Entorno Virtual de Aprendizaje para optimizar la gestión de la información y comunicación de la información entre los agentes implicados en la asignatura Practicum. Inicialmente presentamos una revisión sobre el tratamiento que dicha asignatura ha tenido desde mediados del siglo pasado hasta la actualidad en el estado español. Finalmente presentamos los resultados de un estudio piloto realizado con los estudiantes de Magisterio de la especialidad de Educación Física, que ponen de manifiesto las actitudes positivas del alumnado hacia el uso de las TIC y la percepción de la importancia que las mismas tienen dentro de los contenidos curriculares, por lo que, éstos elementos promueven el desarrollo de competencias no solo genéricas, sino también transversales, favoreciendo de este modo el desarrollo socio-personal y profesional.

Event-based visual servoing

Traditional visual servoing systems have been widely studied in the last years. These systems control the position of the camera attached to the robot end-effector guiding it from any position to the desired one. These controllers can be improved by using the event-based control paradigm. The system proposed in this paper is based on the idea of activating the visual controller only when something significant has occurred in the system (e.g. when any visual feature can be loosen because it is going outside the frame). Different event triggers have been defined in the image space in order to activate or deactivate the visual controller. The tests implemented to validate the proposal have proved that this new scheme avoids visual features to go out of the image whereas the system complexity is reduced considerably. Events can be used in the future to change different parameters of the visual servoing systems.

Guidance of robot arms using depth data from RGB-D camera

Image Based Visual Servoing (IBVS) is a robotic control scheme based on vision. This scheme uses only the visual information obtained from a camera to guide a robot from any robot pose to a desired one. However, IBVS requires the estimation of different parameters that cannot be obtained directly from the image. These parameters range from the intrinsic camera parameters (which can be obtained from a previous camera calibration), to the measured distance on the optical axis between the camera and visual features, it is the depth. This paper presents a comparative study of the performance of D-IBVS estimating the depth from three different ways using a low cost RGB-D sensor like Kinect. The visual servoing system has been developed over ROS (Robot Operating System), which is a meta-operating system for robots. The experiments prove that the computation of the depth value for each visual feature improves the system performance.

Las nuevas tecnologías al servicio de la formación de traductores literarios

El Libro blanco, título de grado en traducción e interpretación, publicado en 2004 por la ANECA, revela que "la especialización en traducción literaria es minoritaria". Así que ¿qué se puede hacer para formar adecuada y eficazmente a los estudiantes que quieren dedicarse a esta parcela tan particular? Para responder a tal cuestión, en primer lugar, estudiamos el proceso de la enseñanza-aprendizaje de la traducción en la era de las tecnologías de la información y comunicación. A continuación, describimos el entorno de trabajo que utilizamos para adaptarnos tanto al EEES como a las necesidades del mercado. Por último, damos a conocer una serie de actuaciones llevadas a cabo en el marco de un máster de traducción literaria.

Alumnado con necesidades específicas de apoyo educativo de Educación Secundaria Obligatoria y el consumo de las TIC en la Región de Murcia

Este artículo tiene como objetivo abordar la dimensión formativa y comunicativa entre las Tecnologías dela Información y la Comunicación (TIC) y el alumnado de Educación Secundaria Obligatoria para establecer un mayor conocimiento sobre qué y cómo estos jóvenes las usan, acceden a sus formatos e interaccionan con sus contenidos. Así se presentan los resultados de una investigación, realizada en 15 centros educativos de titularidad pública y concertada dela Comunidad Autónoma de la Región de Murcia (España), en la que se ha pretendido conocer el equipamiento, uso y consumo de medios digitales (Internet, redes sociales, teléfono móvil, consola de videojuegos y televisión) del alumnado con necesidad específica de apoyo educativo, según la LOE (2006), escolarizado en 3º y 4º de Educación Secundaria Obligatoria (ESO) y la existencia de diferencias respecto del alumnado sin dichas necesidades educativas. Para ello, 2734 alumnos, de los que 487 tenían necesidad específica de apoyo educativo, participaron a través de un cuestionario de 73 ítems con cuatro opciones de respuesta. Los datos fueron analizados con el paquete estadístico SPSS for Windows 15.0, utilizando estadísticos descriptivos. De los resultados conseguidos en esta investigación destacamos que en todas las dimensiones analizadas no existen grandes diferencias entre los dos grupos de alumnos que hemos establecido, pues se aprecia que determinados medios digitales usuales, como Internet, teléfono móvil, consola de videojuegos y televisión, son utilizados por todo el alumnado participante. No obstante, existen matices importantes que marcan diferencias entre ellos.

Energy-efficient self -organization of wireless acoustic sensor networks for ground target tracking

With the developments in computing and communication technologies, wireless sensor networks have become popular in wide range of application areas such as health, military, environment and habitant monitoring. Moreover, wireless acoustic sensor networks have been widely used for target tracking applications due to their passive nature, reliability and low cost. Traditionally, acoustic sensor arrays built in linear, circular or other regular shapes are used for tracking acoustic sources. The maintaining of relative geometry of the acoustic sensors in the array is vital for accurate target tracking, which greatly reduces the flexibility of the sensor network. To overcome this limitation, we propose using only a single acoustic sensor at each sensor node. This design greatly improves the flexibility of the sensor network and makes it possible to deploy the sensor network in remote or hostile regions through air-drop or other stealth approaches. Acoustic arrays are capable of performing the target localization or generating the bearing estimations on their own. However, with only a single acoustic sensor, the sensor nodes will not be able to generate such measurements. Thus, self-organization of sensor nodes into virtual arrays to perform the target localization is essential. We developed an energy-efficient and distributed self-organization algorithm for target tracking using wireless acoustic sensor networks. The major error sources of the localization process were studied, and an energy-aware node selection criterion was developed to minimize the target localization errors. Using this node selection criterion, the self-organization algorithm selects a near-optimal localization sensor group to minimize the target tracking errors. In addition, a message passing protocol was developed to implement the self-organization algorithm in a distributed manner. In order to achieve extended sensor network lifetime, energy conservation was incorporated into the self-organization algorithm by incorporating a sleep-wakeup management mechanism with a novel cross layer adaptive wakeup probability adjustment scheme. The simulation results confirm that the developed self-organization algorithm provides satisfactory target tracking performance. Moreover, the energy saving analysis confirms the effectiveness of the cross layer power management scheme in achieving extended sensor network lifetime without degrading the target tracking performance.

A Formação de professores nas tramas do virtual

This study aims to reflect on the cultural and aesthetics formation of teacher, and how they act as a co-author in the virtual environment. The reflection permeates on topics such as: The Information Age and the challenges of the teacher in the twenty-first century; teacher professional development and the multiple personal identities; the importance of cultural repertoire for teaching practice and the role of the teacher as co-author in the informational network. In addition to the theoretical reflections were conducted two focus groups with the participation of teachers with different graduations and working in various levels of education to discuss the presented topics. It was proposed to create a website for the teacher to sail and collaborate with posts on many cultural artifacts. For the construction of the content for the site, it developed a “daily creation”, which is the search information storage from multiple sources, such as academic papers, songs, websites, magazines, comics, blogs, books, photographs, advertisements, finally everything that can increase imagination and serve for the production of content. Data analysis of the focus group showed that teachers recognize the varied cultural repertoire makes for a good professional aplomb, but cannot actively participate in the local culture. It was also found that the teacher has difficulty manipulating information technology and communication and therefore, distance themselves from an active production network. The focus group contributed to building a website and posts on cultural artifacts. Production can be accessed at www.digitaldoprofessor.com.

Formação inicial do professor de matemática com uso de tecnologias da informação e comunicação no contexto da escola pública

This paper intends to analyze which contribution for teachers formative training the participation on extension projects can bring to the bachelors in Mathematics teaching. The research was conducted during the developing of a Project from the Program of Extension - Programa de Extensão UFU/Comunidade (PEIC) in a municipal school located in a country zone from Uberlândia-MG. The research was constituted by a series of activities with students from the ninth year of the Fundamental Education, Middle School. The main focus is the work developed by two bachelors of Mathemactics teaching from the Federal University from Uberlândia who were part of the PEIC team. This present research intends to answer the following question: How the extension project “Information technology and communication on Mathematics problem resolution in country zone schools” has contribited to reinforce and to (re)criate the fomative experiences of students from the Mathematics teaching course who have developed such project? The presente study is from a qualitative nature and has made use of the partaker searching methodology. The presente paper was organized in three chapters. On chapter I evidence is given to theoretical discussion made, having as main references the works of Larrosa, Ponte e Shön. Chapter II brings the description of the three activities that were developed and aplied during the PEIC Project, which are: Problems in the Park, Inaccessible Hight and Lili Game. On chapter III, the data analysis is presented. The data was obtained through instruments of registration such as: camera recording, photografic material, meetings reports, field notes, surveys and semi-structured interviews. The initial hypothesis aim is on the fact that the participation on extention projects during the graduation course can bring rich contribution for the teachers to be, since it’s going to provide the knowledge and chalenge close to the one from the future profession. With the analysis of the obtained results from the colected data, it was possible to conclude that the PEIC has provided the bachelors in Mathematics teching the opportunity of recreate and potenciate their formative experiences. Such opportunity happened in situations that involved, for example, planning makings, development of colective work, softwares usage, different school spaces and the direct interaction with school bureaucracy. Beyond that, it was possible to work with the cocepts of reflection in action in a way to contribute to the professional development of the future Mathematics teachers. Thereby, in our final considerations, is possible to conclude that extension projects performed during the graduation course can bring great contributions to the professional formation of the bachelors in Mathematics teaching, among them we highlight the potentiation of the previous formative experiences and the development of colective work and behavior related to a reflexive teacher.

Comunicação em MOOC: estratégias e recursos comunicacionais adotados em cursos MOOC

A comunicação é essencial para a vida em sociedade. Na atualidade, com o desenvolvimento de novas formas e possibilidades tecnológicas a comunicação se faz presente também no âmbito educacional utilizando as Tecnologias da Informação e Comunicação (TIC) para atender às exigências sociais e educativas. No caso da educação on-line, os MOOC – Massive Open Online Courses, vêm ganhando destaque e constituem um modelo recente de educação e formação, com a possibilidade de democratização e acesso ao conhecimento e à informação, disponível a um número cada vez maior de pessoas. Neste sentido, o objetivo deste estudo é o de analisar as estratégias e recursos comunicacionais utilizados em cursos MOOC, visando elaborar diretrizes a ter em conta na construção de um curso desta natureza. Para tal, optou-se por uma investigação qualitativa, de natureza exploratória-descritiva, em que a revisão bibliográfica e a construção e aplicação de um modelo de análise dos recursos e estratégias comunicacionais utilizados nos cursos ofertados em plataformas MOOC, integram a metodologia do estudo. Como principais resultados destacamos que os vídeos e fóruns são os recursos mais utilizados nos cursos analisados, observando-se uma tendência de práticas mais empiristas e tradicionais, há pouca utilização de recursos lúdicos e uma ausência do uso de redes sociais como recurso comunicacional. Para além disso, não é utilizada a avaliação dos cursos pelos alunos e predominam as estratégias avaliativas de escolha múltipla. Visando compartilhar as experiências e reflexões advindas desta pesquisa, são apresentadas, ao final, recomendações que podem contribuir para a elaboração de cursos MOOC.

LIBRARY: A DEFINITION FROM ANOTHER CONTEXT

This essay presents a series of discussions revolving around the discipline of library professionals who are trained in it.It covers the concept of Library from the formal point of view, contributed by some authors and dictionaries, but also from the particular vision of the author, who conceptualized from the working level, academy, research and daily contact with users.Therefore, it is a short journey from the traditional to the current reality with the inclusion of information technology and communication. But above all, a journey of a very personal feel.
