I am using blogs again with my students of Image. This is a group of Polytechnic students studying English as a subsidiary subject (once a week for a 2 hour class).
I started using weblogs with the group last year and it was successful. This year I asked the 2nd years if they wanted to continue and they all said yes. It was a lot easier introducing the 1st years to the idea of blogging too as they were able to ask their classmates (the 2nd years) if they had any doubts.
So far we have managed to set up the blogs and start posting on subjects related to cinema and photography. I need to sort out a few problems with links / invitations from individual Student blogs to the Tutor blog, but otherwise it's going well.
I have to give this group assignments and use what they produce in their blogs as part of their evaluation.
