Wow Ro, YOU AGREE WITH ME!
I just don't understand why you insist on equating training students for emergency situations to bullying.
Come on, you're better than this, man. The only assertion I'm making here is that equating "fun" to substandard training is absurd.
I simply see no reason to bully someone in order to teach them any of the emergency procedures in a scuba course. I also see no reason why the instructor would need to become heavy handed with students and take the fun out of learning these skills in order to convince themselves that the skill had been sufficiently learned.
I generally think that being heavy handed is more about the instructor's inability to be even handed than it is about any kind of teaching technique.
That's not to say that there aren't times when you really need to make a point. Last year I had a student who was having a lot of trouble remembering to check the SPG and I asked them at one point, "how long do you want to live?" Some times you need to wake them up, but as a rule, I think being heavy handed is normally ineffective.
