That really adds clarity to the context. I just focused on the one question that you asked because that’s a major issue in my mind. This issue about the efficacy of online versus offline collaboration is obvious to us (I’m smiling that I wrote a lot of obvious things in the long comment!) but it is not to a lot of students and often teachers who either support or oppose one or the other type rather than assessing the effectiveness of both modes for different purposes, within different limitations (as you added in your response), and for different student demographics. Good discussion. Let me add a link to an article that is really tempering some of the craziness around online education here in the US: http://www.latimes.com/business/hiltzik/la-fi-mh-uc-prexy-napolitano-20140326,0,2067391.story#axzz2xEY2fG00
