I somewhat think the opposite though. When you're given ten ways to do it, then it's information overload and you end up just memorizing those ten ways. When you're given one way to do it then not only do you have a way to do it that will always work, but also it leaves your brain ready to find further ways to do it on its own. And that's how thing start to make sense and stick. Basically, I think for good students, CC just makes them memorize stuff they'd come up with on their own, and for poor students it creates too much confusion such that memorization isn't even effective anymore.
