    Sammanfattning : The convergence of inexpensive video-enabled mobile phones, high-speed mobile data networks and ubiquitous sensing devices opens up a new design space called “live mobile video interaction”. It gives rise to a new genre of applications concerning live mobile video production, which can be seen as an instance of the said space. LÄS MER

  5. 5. Design and use of mobile technology in distance language education Matching learning practices with technologies-in-practice

    Detta är en avhandling från Örebro : Repro

    Författare :Olga Viberg; Örebro universitet.; Högskolan Dalarna.; [2015]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatik; Informatics; online distance education; mobile learning; mobile-assisted language learning; information systems artefact; design science research; learning practices; structuration; self-regulation; technology-in-practice; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : This thesis focuses on the adaptation of formal education to people’s technology- use patterns, theirtechnology-in-practice, where the ubiquitous use of mobile technologies is central. The research question is: How can language learning practices occuring in informal learning environments be effectively integrated with formal education through the use of mobile technology? The study investigates the technical, pedagogical, social and cultural challenges involved in a design science approach.
