> The problem with education is that existing ways of doing things are very strongly entrenched.
Which is still a problem of educating humans. Just moved up the chain one step. Educators are often very hard to educate.
Even mathematics isn't immune to this. Calculus is pervasively taught with prematurely truncated algebra of differentials. Which means for second order derivatives and beyond, the "fraction" notation does not actually describe ratios, when this does not need to be the case.
But when will textbooks remove this unnecessary and complicating disconnect between algebra and calculus? There is no significant movement to do so.
Educators and textbook writers are as difficult to educate as anyone else.
