Online education isn't the Answer to all your imagined problems.

Online education and “gamification” will liberate public school students from the education bureaucracy and help homeschooling expand, he predicts. Young people seeking higher education will have low-cost alternatives to brick-and-mortar colleges. Glenn Reynolds, The Higher Education Bubble .

Homeschooling might expand, but the public school system isn't going to be damaged by online education and "gamification" unless we try to implement this farce ourselves.  The students will simply not cooperate with this blatant attempt to destroy their education, not because they care about the sanctity of public schooling but because they have shown again and again how little motivation they have for teaching themselves everything.

Sorry, Glenn. Hate to burst your bubble.
