Interesting article; however, I would suggest that the Universities themselves are to blame. There were very few courses that I took where the professor encouraged us to talk to one another about problems and assignments. Usually it was the reverse. We were told in no uncertain terms that we were not to talk to anyone else, nor were we to work with other students in the class. Any collaboration was considered cheating and plagiarism.

Obviously, this did not apply to things like study groups, but once you have had it drilled in to your head that collaboration was bad, it is very difficult to then create the network necessary for a study group.

Universities need to change the way they teach and mark such that collaboration is not only suggested, but required. In addition, I think universities, if they really care about these differences, need to create some form of mentoring program for incoming students.
