Ok, well actually teach kids with results focused study. Teach them skills they can use rather than stuff abstract things into their heads.
Here's the thing: We don't teach our kids how to think abstractly
at all. It's about teaching to the test, letter-grade rewards, and rote facts.
In my opinion, one of the biggest problems with our educational system is that we try to teach children what to think without ever teaching them how. Elementary school, in particular, is just a series of regurgitated facts and cultural narratives without much of any emphasis on critical thinking or reasoning of any kind. Because of a combination of this and what I mentioned in the last paragraph (and probably some other things), it's no wonder that general skills like math and reading aren't up to par, because our testing methods are terrible, we have trouble teaching kids
concepts instead of tabular facts/data, and nobody teaches them why any of it is important, or how to come to conclusions rationally.
See, things like math and physics aren't taught abstractly
enough. It's all formulas and facts to be memorized for tests, whereas if you were to give children a conceptual and abstract background, they would actually understand it as well as have less reason to memorize things in the first place, along with having an actual appreciation for the subject and how it applies to their lives (which is obviously something we both consider important; teaching things on a practical level is one way to get people to really understand it). I've seen tons of people who did "well" in high school math, yet don't really understand the concepts at all; they just did well because they crammed formulas into their heads for tests, and had no reason to believe they should have been doing anything else.
