I often use the Discussion feature as a Do Now activity for students in my classes. I try and reward students with points for participating in the discussions daily. Sometime going through the Speedgrader to grade these can be a longer process than what is necessary. I think if we could somehow include a grading box right along in the student stream where they post, it would be much easier to read replies, ensure student understanding, as well as saving time to grade students 1 by 1.
