In a stall situation, I'm maintaining direction(preventing yaw) with the rudder, whilst arresting the wing drop by reducing the angle of attack.
This is also incorrect and would be very dangerous teaching with a stalled condition in a multi engine aircraft with one engine inoperative.
The rudder is the primary control used to PREVENT further wing drop. Reducing the angle of attack below tbe critical angle prevents loss of control and unstalls tbe aircraft, the secondary reaction to this is that as control is regained a stable aircraft will reduce but not necessarily eliminate all of the yaw produced due to the stability provided by the fin and fuselage.
