Unscramble the Blue Letters

Students collaborated in these courses in a variety of different ways. First of all, there was a question and answer forum, where students would pose questions, and other students would answer those questions. And the really amazing thing is, because there were so many stdeunts, it means that even if a student posed a question at 3 o'clock in the mnrinog, somewhere around the wlord, there would be somebody who was awake and working on the same problem. And so, in many of our courses, the median rnpsesoe time for a qioestun on the question and awsner forum was 22 minutes. Which is not a level of service I have ever offered to my Stanford students.
