I remember high school very well, and it was a pretty torturous experience. If you could design an educational program that was almost guaranteed not to be a conducive learning environment with poor mastery outcomes, the public k-12 system in the U.S. would probably be it. Even worse, when they measure educational outcomes, the place systems like South Korea's at the top, a system that's absolutely optimized and excels at the lowest possible form of learning, rote memorization.
In the previous discussion, I point out that I believe students need to "complete the circuit", go from input/reception to output/production to say they've learned a topic. In today's school environment, if this happens at all, it happens by accident:
1) The teacher gives a lecture, information is shoved in
2) The students do homework and tests, okay, the students "produce" what they've learned, usually a brain dump of what they've memorized, but let's be honest, not a demonstration of learning or mastery.
3) The homework and tests get an impersonal grade, the "feedback loop" necessary to complete the circuit. But if the student got it wrong? Too bad, the lesson is moving on anyways. There's no time really spent in education to have the student go back with this new course correction and see if they got it now. And out of schedule help in most schools is woeful.
Because of this systematic failure, by the time many students are involved in "advanced" topics in high school, their foundational knowledge is so flimsy and filled with holes that new topics are like turning a strong fan on in a room with a house of cards. Yet the professional educational establishment seems unable to figure this out and correct it.
Keep in mind, without even a template of any kind, we're all fluently able to learn a complex language, a mass of complex social rules so complex that libraries are full of books describing them and how to sanitarily complete a digestion cycle on our own (everybody poops) before we even show up for day 1 of 1st grade. Keep in mind that we spent the first two of those 6-7 years not even being able to talk - so we did all that in about the same time it takes to get through high school. If we learned as much in our 4 years of high school, we'd all be leaving with the equivalent of advanced degrees in physics.
Children can learn at phenomenal paces, yet it takes years before students accumulate any worthwhile new skills in this kind of environment -- skills that should take them weeks or months.
School is doing it wrong.
