This is a deep subject, which would be worth an encyclopedia, even a library for itself. I will have to content myself with one example here. My mentor in many things told me early on in our collaboration that she couldn't do algebra, although she had learned the formulas and procedures. The problem was that she had been told, "A variable is a number that changes its value." This is total nonsense, and she knew it. One of the hardest, most reliable facts in the world is that any number is the same as itself and different from all others, and never changes. I don't know how this collision of ideas made her unable to use procedures that she had memorized, but I had to believe her, and so should you.
 +
 +
I explained that variables are just like pronouns. When I say "I" and when you say "I" we are referring to different people, and similarly for the other pronouns and other words of variable reference: you, he, she, it, we, they, this, that, here, now, and so on. "Noon on Tuesday" cannot become midnight, but "now" runs through every possible time. In just the same way, x, y, z, and the rest can be 3 or -4, or can run through all numbers.
 +
 +
She went away for 20 minutes to try this out on what she remembered, and returned saying, "I can do it all now." That was the end of that. Mathematicians who have taught middle school have many more such stories.

It is widely assumed that failing to pound the prevailing theories on these matters into the brains of children is a recipe for unmitigated disaster. If we don't force them to adopt the prevailing wisdom, the thinking goes, they will grow up with no sense of what is real and what is fantasy, no respect for truth, and no ethics whatsoever. Actual experiment tells us otherwise. It is true that giving no support to children would turn them into lunatics, but that is not what we are talking about. We want a cohesive society based on mutual respect, not on groupthink.

One of the best historical examples occurred in in The Netherlands early in the 80 Years War with Spain, when the Dutch declared Freedom of Trade and Freedom of Conscience to be their founding principles, in rebellion against the Spanish Imperial economic laws forbidding spending any of the treasure from the Americas outside the Empire, and against the Spanish Inquisition. Everybody in Europe, including many of the Dutch, predicted with great confidence that their society would collapse almost immediately, and were confounded when The Netherlands became for a time the richest country in Europe, and the intellectual and scientific center of the world. Similarly, those who invite children to learn, and support them in learning, rather than forcing them, find that the children learn their school subjects as well as or better than anybody else, and many other essential skills of life much better.

Even in mathematics there must be room for the exploration of ideas and of alternatives. Most people assume that mathematics is a science of perfection in which everything is defined with complete clarity and proved with complete certainty. Mathematicians

proof, either, in large part because the "obvious" definitions were found to be full of holes in a difficult period in the late 19th century. Everything has been patched up an a fairly workable way, but there is a lot not to like still. Basically, the problem is that math wants to deal with infinities of infinities, but humans can only use finite methods.

Philosophy is the worst case from this point of view, because it takes on the questions where we have no method for finding answers, or where answers may not exist.

Perhaps the education of children should mirror the education of humanity over some thousands of years. Any advances require the freedom to question the correctness and completeness of current answers, a freedom that has existed in relatively few places, if any, throughout most of our history. Of course, we humans don't often treat our artists, scientists, and other discoverers any better than we treat our children, except for the few who break through to become superstars.
