Well this session went pretty smoothly for me. So far, I found that having a look at the worksheet prior to the session is a big help; it allows me to get a general idea of where I'm going and work on potential problems beforehand, some of them anyway. I agree with Philip, the problem is not how to do things (we are all smart and talented!), but getting suitable ideas, especially for advanced levels, and willing participants. I'd love to record a short oral presentation as a model for students to have a look at but, not surprisingly, most people are reluctant to be filmed and posted on YouTube. I guess I'll have to do it by myself again. Love your interview example Philip. By the way, How did you do the rolling credits on your clip about image resolution? It added a very professional savoir-faire. Impressive!
