Anything that works for anybody is better than what we have now.

Works for me.

Yes, that is indeed the key point. With the background of
Constructivist child development research plus the awesome power of
software (Awww!) it becomes a considerably more fraught enterprise.
The whole modern curriculum grew out of medieval roots in ways that
have nothing to do with the connections of ideas and everything to do
with who published what when. We are not supposed to teach any math
significantly later in origin than the 17th century to secondary
students, no matter how easy it is to learn and no matter how much it
would help.
When we know the fundamental ideas of a branch of mathematics or any
of the sciences and can express them in various "age-appropriate and
intellectually honest" ways (Bruner), we are nevertheless not allowed
to present them before the age at which conventional wisdom says a
subject can be started. We can explain the fundamental concepts of the
calculus (direction of curves, maxima and minima, area under a curve,
and others) visually to preschool children using no symbols and
performing no calculations. We could add to that understanding year by
year as the children get to be able to handle more advanced geometry,
arithmetic, algebra, and proofs, so that when the time came to teach
full formal calculus, we could do the current first-year course in a
month or less. But no chance.
Similarly with computers, where society will not permit Boolean
algebra to be taught in school, so that students coming to Boolean
logic in programming have no foundation for understanding it.

This delusion is not specific to education. Coding is the easiest part
of any problem. Understanding what the problem is ils always much
harder, but industry long ago settled on a metric (lines of code) that
makes the real work invisible.

There is reason to think that the proper sequencing and relation of
ideas in a curriculum could make it much easier to get through with
adequate understanding. There is reason to think that going for fairly
full understanding slows down individual topics at first but speeds up
the overall process dramatically once students have had the experience
of understanding something, and know what they are trying to do.

We have had our educational Copernicus, and we may now be in the age
of Tartaglia, Gilbert, Galileo, Huygens, Kepler, des Cartes, Leibniz,
Hooke, and so on, but our Newton has not yet manifested. Perhaps she
will appear among our schoolchildren, who will in due course have a
chance to grow up with fewer of the prejudices that were foisted on
most of us.
