Our paper “Personal learning environments: A conceptual landscape revisited” has been accepted for the PLE Conference 2013 in Berlin, Germany and Melbourne, Australia. Co-authored by Dr. Terje Väljataga the paper will try to provide an overview of the conceptual developments and different strands of research around Personal Learning Environments. We basically focus on what has happened since we presented our paper “Personal learning environments: concept or technology?” at PLE Conference 2010 in Barcelona. That paper was finally published as “Fiedler, S., & Väljataga, T. (2011). Personal learning environments: concept or technology? International Journal of Virtual and Personal Learning Environments, 2(4), 1-11”. Apparently its PLE Conference 2010 version is still accessible, too.
