I was linked to your blog on International Studnet Classroom Interaction and am curious to understand a little more about your research, particularly the 'twitter' and what results you've found.
I'm in the process of completing masters research into UK student mobility and relationships between home and international students in the classroom and find very little valid research out there.
It would be good to exchange the odd idea or two, though with May deadlines we're both probably under a little pressure right now!
