    Using virtual learning environments in bricolage mode for orchestrating learning situations across physical and virtual spaces

    Producción CientíficaTeachers usually implement their pedagogical ideas in Virtual Learning Environments (VLEs) in a continuous refinement approach also known as “bricolage”. Recently, different proposals have enabled the ubiquitous access to VLEs, thus extending the bricolage mode of operation to other learning spaces. However, such proposals tend to present several limitations for teachers to orchestrate learning situations conducted across different physical and virtual spaces. This paper presents an evaluation study that involved the across-spaces usage of Moodle in bricolage mode and learning buckets (configurable containers of learning artifacts) in multiple learning situations spanning five months in a course on Physical Education in the Natural Environment for pre-service teachers. The study followed a responsive evaluation model, in which we conducted an anticipatory data reduction using an existing orchestration framework (called “5 + 3 aspects”) for structuring data gathering and analysis. The results showed that learning buckets helped the teachers in the multiple aspects of orchestration, overcoming the limitations of alternative approaches in some specific orchestration aspects: helping the involved teachers to connect different physical and physical spaces, while supporting technologies and activities of their everyday practice, and transferring part of the orchestration load from teachers to students. The results also suggested lines of future improvement, including the awareness of outdoor activities.Ministerio de Economía, Industria y Competitividad (Project TIN2011-28308-C03-02 and TIN2014-53199-C3-2-R)Junta de Castilla y León (programa de apoyo a proyectos de investigación - Ref.

    Digital technology in mathematics education: Why it works (or doesn't)

    Get PDF
    The integration of digital technology confronts teachers, educators and researchers with many questions. What is the potential of ICT for learning and teaching, and which factors are decisive in making it work in the mathematics classroom? To investigate these questions, six cases from leading studies in the field are described, and decisive success factors are identified. This leads to the conclusion that crucial factors for the success of digital technology in mathematics education include the design of the digital tool and corresponding tasks exploiting the tool's pedagogical potential, the role of the teacher and the educational context

    Algorithms for advance bandwidth reservation in media production networks

    Get PDF
    Media production generally requires many geographically distributed actors (e.g., production houses, broadcasters, advertisers) to exchange huge amounts of raw video and audio data. Traditional distribution techniques, such as dedicated point-to-point optical links, are highly inefficient in terms of installation time and cost. To improve efficiency, shared media production networks that connect all involved actors over a large geographical area, are currently being deployed. The traffic in such networks is often predictable, as the timing and bandwidth requirements of data transfers are generally known hours or even days in advance. As such, the use of advance bandwidth reservation (AR) can greatly increase resource utilization and cost efficiency. In this paper, we propose an Integer Linear Programming formulation of the bandwidth scheduling problem, which takes into account the specific characteristics of media production networks, is presented. Two novel optimization algorithms based on this model are thoroughly evaluated and compared by means of in-depth simulation results

    Context-Aware Service Discovering System for Nomad Users

    No full text
    International audienceThis paper presents an architecture for a system that provides nomad users, context-aware personalised services. Users might need any sort of services: information about the weather forecast for the next day, or about a museum in the neighbour worth to visit. These services are known as stateless services. More complex situations ocurre when services are stateful. Such services are, for example those which need users to be logged in (e.g. booking a room in a hotel). The question discussed in the text are those related to: i) user's privacy, ii) recommendation and discovery of services, iii) composition of recommended services into a composite service, and iv) execution of the resulting composite service
