The bottom line is I want to instill an instinctive reaction of stick forward and rudder as required to arrest any yaw for any possible inadvertent stall. If that is there is no way a student can get him or herself into an inadvertent spin.
This is a logical approach but I don't agree with it. If you get into a spin inadvertently it really means you missed all the warning signs. If you are trained only to recover from those warning signs and you missed them because you were distracted or overloaded then you have nothing left in your armory of practical flying skills to get you out of trouble.
Your first spin in training with an instructor where you have been briefed beforehand and are expecting it, still feels very unusual and takes you by surprise. For a pilot that had never experienced that before, I doubt they would stand much chance of recovery.
