To give the article itself the same MST3K treatment they gave the Kahn videos, a much better demonstration of the difference between mechanical skills and "judging between two equivalent concepts" would focus around shell vs disk integral calculus methods. Trivial to teach the mechanics of either, and the names are very intuitive of what they do, but it takes some experience and discussion to internalize when to use which strategy.
