I'm surprised no one has mentioned Bryan Caplan's The Case Against Education yet, which basically argues for a revolution in the other direction - get rid of almost all schooling because almost none of it passes a sane cost benefit analysis. It's very well researched, and the author has a long track record of being happy when he moves people even marginally towards his views.

The praise here for Direct Instruction is akin in many ways to a lot of the research Caplan draws on, especially his findings that generally, most work related knowledge is built at work, by actually performing the job.
