"Changing the delivery system might serve to make private education both more affordable and more different, and signs of such change are already evident, but rarely in the traditional nonprofit portions of the private sector. Instead, the boldest innovations are coming from entrepreneurs, most of them profit-seeking and most of them delivering instruction (and more) via technology rather than face-to-face in brick buildings that are open just six or eight hours a day for 180 or so days a year. Or elite universities — the ones that are still thriving and would continue to thrive without these changes — are, themselves, innovating — mostly for students other than their own. The MITs and Stanfords are teaming up with the Courseras and Udacitys — educational technology companies specializing in online education — to offer online courses to thousands. Udacity has put a toe into the K-12 waters, both by partnering with local school systems and by inviting students to enroll directly in its college-level courses. Nor is it likely to stop there. Indeed, I expect “St. Paul’s math” and “Dalton’s literature” in time to echo across the land, too. If current trends continue, we’re going to see a bi-modal system develop, with public schools (including charter schools) and ultra-elite private schools monopolizing the education space as the plethora of smaller private and parochial schools that once fell between them gradually fade away."
