I agree with Cory. We have to try different formats and activities and see what works best. And, again, it will work differently with different teachers and different groups. I suppose Rick wants to work with the writings, so the activities have to be more guided and the teacher’s role will be to work on vocabulary and structure. The challenge is how to address these issues on the blog. How are you going to give sts feedback? Using editing tools? Posting your feedback on the blog? Printing and making comments? Waiting for other sts’ feedback? I suppose you can always discuss it w/ the sts and see how they feel about it.
