To a certain extent that's a product of a bad curriculum though. If you teach something, tick it off, teach something else, tick that off. And build a large number of things ticked off in that manner - that don't reuse the things taught earlier - then of course you're not going to get the reps in. As compared to, say, the syntax in a programming language. Where you don't write out hello world sixty times to get the bracket rules, you just reuse the rules in other things you're doing often enough that they become ingrained.
