I've done some instructing with the Tire Rack Street Survival school for new drivers. The skid pad was very enlightening. It is fairly easy to teach people to recover from a tail slide (oversteer), because the "steer where you want to go" bit is really fairly intuitive once you get it.
What is NOT easy to learn is understeer/plowing recovery, because our instincts are so wrong. When the car won't turn, everyone tries to turn the wheel farther. That makes it plow worse, and whatever we don't want to hit is getting closer, so we crank it even more. Boom!
The trick is to straighten the wheel a little instead of turning it more. Yes, you will turn tighter if you straighten the wheel. Not all the way, of course, but straighten until it starts turning.
At first, try it while being steady on the gas. Once you get that down, try lifting your foot off the gas just as you straighten to get some forward weight transfer.
Be ready though! These techniques works so well that the sudden traction may catch you off guard. Be ready to keep straightening to exit the turn.
