"AMERICA HAS TOO MANY TEACHERS": This one would smack of a summertime jolt to drive web traffic except the author, Andrew J. Coulson, has a long history of writing about schools as overgrown monopolies. Once a Microsoft engineer, he's presumably happy, ensconced in the rabidly free market Cato Institute's Center for Educational Freedom. Here's one asserted--but not supported--comment: "Even as a tiny, mostly nonprofit niche, American private education is substantially more efficient than its public sector, producing higher graduation rates and similar or better student achievement at roughly a third lower cost than public schools (even after controlling for differences in student and family characteristics)." Really?? Would love to hear your thoughts on his piece and his stats--and will share a few next week. (Or tweet 'em out today @edsurge)!
