Aproaching the stall you are right and in most modern aircraft you will be ok using rudder/aileron in the stall, but teaching SHOULD be - approaching the stall keep the aircraft in balance with rudder and control roll with aileron - IN the stall, Ailerons central and PREVENT FURTHER WING DROP with rudder (you DO NOT roll the wings level UNTIL you have recovered from the stall). To say you will not spin if you stay coordinated is NOT correct, MOST modern machines won't but I have ended up in a spin from a barrel roll with the ball inthe center in one machine at over 90kts ( 1G stall 42kts),putting the aileron in to stop the roll causing the inboard wing to stall!
