Typically the way it's taught (at my school at least) is that they introduce the definition of the derivative, with the clunky limit stuff, and make you do a couple homework assignments using that. Then they teach you Power Rule and the rest.
Of course, half the students find out about the shortcuts before they're supposed to.
