Yesterday I gave a masterclass about mobile learning, you can watch the dutch video at:
or participate at the masterclass in dutch at (it’s free! thanks to sponsoring of SURF Academy)
One interesting issue of discussion was the question what different affordances different mobile technologies can offer and how this has consequences on the instructional design of mobile learning. I think this is definitely an interesting issue and if someone knows any research papers on this issue I would be interested to get some recommendations.
