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.

Most cranks are.
Caplan is a radical libertarian bent on annihilating what few functioning social institutions we have left.
I cannot imagine coming to a place that has a reputation of having higher educated people, and presenting that education is a waste of time. All research has some levels of agenda behind it, and it would be very easy to steer anything the author presents into a direction he wishes. On the contrary, literally every country on earth benefited greatly from education and the results are very visible in all aspects of human development (HDI, GDP, pollution, literacy, etc...), most recently China, and even more recently India. Both had huge numbers of illiterate people, compared to both advancing at an incredible pace when a large emphasis was put on education.
