I am interested in philosophical and pedagogical aspects of networked learning - and of knowledge and the design for learning in general. In my research I try to bridge between epistemological analyses of what knowledge is and practical pedagogical recommendations I do this by analyzing learning theoretical implications of the former for the design of pedagogical practice - and conversely by challenging the philosophical analyses with the results of implementing the recommendations in practice. I have a special focus on web 2.0-mediated learning.
