This video talks about high school curriculum design issues; advocating greater focus on concrete life skills and less of a focus on classes with "intangible" value like history or more advanced mathematics. If I recall correctly, he doesn't say anything about science class, which I think there's a lot to criticize there too. A lot of common counter-arguments to his point do not seem scientific. The argument that history teaches critical thinking for instance is very popular, but there's no good definition of critical thinking and research seems to be all over the place. I generally agree that education should provide more direct value. The commentary I saw on it kept bringing up the issue of standardized testing which is unrelated. I don't hold much hope out for improvements when the average person can't even stay on topic.
