Hermie, there is some complete rubbish being posted here. Talk to your Instructor and get him to explain exactly what he means.
I was also taught to use rudder during final approach to pick up a wing (this is what I think he means) and anyone (and I mean anyone that can fly a real aeroplane) knows that during slow flight you should be careful using coarse aileron.
If in doubt, ask your Instructor. Trust is very important and your Instructor wants you to learn to fly properly and safely.
Frankly, I can't believe some of the ridiculous comments on here. e.g. what on earth is a yolk? Ye gods!
