Trying to recover from a stall by increasing power is just plain daft, the person who came up with the idea should be shot..
Adding power in many aircraft types may actually result in an increased AoA, especially low wing types with underslung engines.
I was always taught to get the nose down FIRST then consider adding power once the stall is broken.
This is probably a result of the mistaken teaching of "stalling speed", a wing stalls at an angle of attack, (usually around 15 degrees) not at some magic speed.
