I give the good and bad...I have found sometimes that the bad gets them talking...whether it is showing them that they don't have to be perfect or what, I know it works.
I will give them what happened, how I handled it and ask them how they would have handled it. This really gets them involved, and honestly, they are thinking through the answers, because if they post before they have thought them through, the other students point out the loopholes...
I think these are sometimes the liveliest and sometimes the funniest discussions!
