I think this is an important point of this study because one possible criticism of MOOCs is that they might only work for people who are already very high functioning and good at figuring stuff out themselves, and people who are more apt to struggle might be left completely in the dust (more so than in a live-contact situation). So the fact that this was not true is interesting.
