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.

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

When I was a student at Princeton University, I was working part time in a grocery store. I saw an ad for teachers of a prep course. I don't remember what it paid, but it was easily double or triple the minimum wage.

I studied to be an architect. And I find tremendous similarities between building a company and the design process. Businesses have to do their planning on the fly in a fashion similar to an architect sketching.

No two children learn in the same way. While we might agree that every American eight-year-old should be able to read and multiply, beyond those basics, there are few reasons to make every student follow the same path.

Almost everyone who has claimed to know what kids need to learn or how they learn has turned out to be wrong.

I'd never taken an SAT prep course. They were for weaker students.
