I think the "Three Steps" idea is the cat's meow, but like anything else, it has it's goods and bads. I really like the use of ACTION words and putting them in place of obscure (to the student/trainee) verbeage like rotary, edge, pressure. Hmmm. Tipping, Turning, Flexing/Extending... Just sounds like you can actually DO those things.
From a teaching standpoint, I agree that too simple would not be good. But as Bob has said, the use of this idea does not negate anything I already know. I've found that when applied in the right context, "Three Steps" can really take both the work and the talking out of the lesson. In the season that I've become familiar with the idea, I've been able to experiment with some really fun lessons!!
Anyway, I just wanted to say that I am a huge proponent of "Three Steps" and I look forward to its progress. It does have a ways to go, but from a student's standpoint, I think it is a good beginning.
CAUTION: Instructors, you will still need to know all the things that instructors are supposed to know! "Three Steps" hasn't Replaced anything in my itinerary, just enhanced it. It's just as dogmatic as anything else out there... be it Centerline, PMTS, Perfect Turn, Art of Carving, etc. When we, as teachers, take the simple truths from any "program" and communicate those truths in an understandable way, we can't help but win in the end.
