Is there a way I can check if a student has replied to all of the questions in a Question & Answer forum?
During a course I usually post about 25 questions and I want each student to post a reply to each question. I know that I can see how many posts they've made, but it is possible that they replied more than once to one question but not at all to another. There is also the problem that, if a student hasn't replied to one or more of the questions, I don't know which ones she's missed (and neither does she, probably) without looking through every response to every question.
Ideally, there would be a completion criteria for Q/A forums that says "Replied to every question." Failing that, is there any way to do this?
