One way to teach people what they don't know is to teach abnormal attitudes, spins and how to make balanced turns, steep and rate one. Most importantly put a lot more effort into stall and stall recovery at all attitudes. Teach pilots to overcome the counter intuitive response and train an instinctive response to stall and stall onset.
You need to show students just how quickly it can turn to shit by putting them in situations they should not be in and then recovering or have it scare them so much they never do what you have demonstrated.
Trouble is there are bugga all RAAus instructors with that level of competency. I had the pleasure of many instructors since I was 16 years old and one cranky old bugga stands out. I owe my life to him because one day when I got into trouble all his training flooded in and saved my bacon. I would have been another of those 34 year old fatalities way back then. My survival was a result of effective training ... did you get that ... my survival was a result of effective training. Effective means he taught me and I learned ... not just the first part.
If you don't understand the risks, you don't know you are taking them. We need to instill a life preservation instinct.
Many can teach ... but ... the litmus test is ... did the student comprehend, learn and did his competency improve?
