I hated being a public company CEO.

Why do men outperform women on the SAT? The SAT's supposed to predict college grades. Women do better in high school and they do better in college. What's the problem here? Ah, the more you use, the more you start accepting that the SAT's coachable, the more problems you have with it.

The Internet will save higher education, but it may kill your alma mater.

The Internet rewards scale; by trading higher up-front costs for lower marginal cost, market leaders can invest in better technology and service. As a result, there is nothing online that is both great in quality and small in scale. Amazon wasn't originally a better bookstore than the small shops we mourn, but it is now.

You still remember your SAT scores. And everybody else does too. Everybody's forgotten everything about themselves, everything else about high school. They remember their SAT scores.

The Internet is the first technology since the printing press which could lower the cost of a great education and, in doing so, make that cost-benefit analysis much easier for most students. It could allow American schools to service twice as many students as they do now, and in ways that are both effective and cost-effective.

Traditionally, universities have seen size as potentially dilutive to quality. If you doubled the size of campus and faculty, most would argue that you would make it a less compelling school. However, online schools will be as good as their classroom peers only if they are large enough to afford a substantial and ongoing investment.
