Article on Mashable, a social media website, gives a good overview of many of the same innovations in higher education I cover in my new book...Open CourseWare, Flat World Knowledge, University of the People
One of the commenters raises a question I've been mulling over. "I would like to see innovations that problem-solve around issues of FULL access to higher education (and quality k-12 education for that matter) for low-income communities in the US and around the world. This includes opportunities for learning that necessitate physical learning communities that dominant groups will surely continue to build for themselves... I fear that those with the resources to take these innovations to scale will focus their energies around notions of campus-free learning to the detriment of those whose only economical option might be such incomplete learning opportunities, thus dangerously perpetuating a tiered system anyway."
I think in any society you can imagine, there is going to be some inequality and the school system is going to reflect that. What distinguishes the current round of innovations in open education, from what I've seen, is an unusual amount of cross-institutional collaboration from Ivy League colleges to community colleges, and internationally, too.
Also, campus-free learning doesn't have to be seen as incomplete, but complementary to a course of lifelong learning, seeking out learning communities for oneself and incorporating one's life experience as well.
