Application of rudder is to prevent yaw, most aeroplanes will only yaw if you forcefully boot the rudder, yank on the ailerons or apply power. Most aircraft will recover without any input from the pilot at all.
Unless the aircraft is in a fully developed spin use of rudder will probably just make things a lot worse. Ref the Avweb video with the Cirrus going into a snap roll at about 200 feet AGL because someone did exactly this, it is a vid I show students before the stalling lesson.
Plus a proper analysis rather than old wives tales here

"One feature that stands out in all except one of the 39 stall/spin accidents examined is that knowing how to recover from the stall or spin was of no benefit to the pilots in these circumstances. They stalled at altitudes so low that once the stall developed, a serious accident was in progress"
This is what students need to study, not have instructors yank and shove little aeroplanes around at 3500 feet.
