I have found that teaching the stude to use rudder at the stall to 'limit further wingdrop' can actually lead to 'EXCESSIVE AND OVER ENTHUSIASTIC' opposite rudder.......leading to SPIN!
I simply teach the stude to lower the nose gently to unstall (OK, stick to centre then forward), full power to accelerate, then when the a/c is flying again to use ailerons and rudder in normal fashion.
Why make it such a black art? Keep it simple I say
