I don't want to rely on peer ratings, I want an actual teacher grade. Of course, one of the problems is that you can't just "add a grade" in the grade book. Okay, so I can get around that by setting up a forum to allow rating and then overriding student rating--but it seems that the student can still see their own rating. So, do you rate every post? Not practical. Do you rate random posts? You can also add a hidden assignment, then give everyone a grade for discussion participation--but I really don't like that idea.
Aside from that, what are some ways you grade discussions? Do you give "points" for each discussion. Do you give a separate grade for discussion content? How?
I didn't find the right solution from the internet.
