Naw man, you've gotta know the trick about "more right rudder."
As you can see, when you're doing power on stalls, it only works for so well. I told my students "more right rudder" through three stalls. After that, we'd climb to about 7,000' and I'd have them do a power on stall and say nothing.
After about their second time putting the airplane through a solid half turn in a spin they'd figure it out REALLY fast.
Seriously, their power on stalls progressed MUCH faster once I just let them start to spin it a little bit. Then they'd always say, "Oh WOW! I get it now! It just didn't make any sense until I saw it develop!"
Just make sure you have enough altitude to recover. Normally I'd do it with my feet on the rudder pedals and arms folded and they'd say,
"OH MY GOD WHAT'S HAPPENING! WHAT SHOULD I DO!!!!"
"Try some right rudder?"
".......HOLY CRAP YOU WERE RIGHT!"
I miss teaching. Or more so I miss those students, they were a lot of fun to fly with.
