I suspect so though I can't definitively say. Most of my later learning involved making a ton of painful mistakes many of which I'm certain could have been avoided with some basic help. I genuinely can't link very much I learned in school to helping me learn later in life. Science report writing, one product design class and a school show I performed in are about it.

I can on the otherhand link many things I did outside of school at that time to things I learned later in life.

I don't disagree with your view that the point of school is to teach children to self-teach. But I do disagree that the school system I went through helped very much with that.
