All ab initio stall training should start with the understanding that the point of the exercise is not to teach you how to stall the airplane, it is to teach you how to recognize the aircraft is about to stall and fix the situation before it does stall. However if you are asleep at the switch then it is important that you learn how to quickly regain control. This should always start with reducing angle of attack by smoothly but firmly lowering the nose and then applying full power. Control of yaw at this point now becomes important as if the aircraft is allowed to yaw then it can spin. Effective use of the rudder is the way to control yaw and thus eliminate the possibility of the aircraft departing in a stall.
Even though modern aircraft certification standards require that the ailerons be effective even after the wing has started to stall, ailerons should still not be used to level the wings until the aircraft is definitely un-stalled
The biggest problem I see with ab initio instruction is the exercise is taught with the aim of generating a good mark on the flight test, instead of showing students the real world scenarios that pilots get into trouble on.
