I think that a coupled program would be of great help to a lot of skiers. I certainly believe it would be of great help to me. From my perspective as a student, I can hardly overstate how helpful it would be to understand the instructer's terminology precisely...and to have the instructor KNOW that I do, so (s)he can rely on it during the lesson(s). Also, a mutual understanding of the mechanics underlying the movements the instructor is trying to teach would be invaluable. Again, not only must I understand the instructor's take on the mechanics, but to be most effective, the instructor would have to know that I understand, and be able to rely on that understanding when deciding on excercises, showing me how it's done, suggesting alternatives, providing me feedback, etc.
You've sort of hit a hot button with me on this one. There are probably a lot of students who wouln't benefit so much from pre-lesson reading and study, and similarly instructors who wouldn't be able to take advantage of the "book learnin" on the student's part, but I believe I would, and I would guess that a lot of us who lurk around the Technique and Instruction forum have of learning style well suited to a coupled program.
If you can direct me to anything written on the Ski Taos Style, I would appreciate it greatly. I took their Super Ski Week last year. I thought it was quite good, but they didn't refer to any coupled reading or lesson plan or Ski Taos Style (at least that I was aware of). I had e-mailed them in advance to see if they had any recommended reading, and the only response was that possibly Warren Witherall's the Athletic Skier would be useful. However, my instructor didn't rely on anything in it and in fact had a criticism of the Burke Mountain Academy's emphasis on (excessive) knee angulalion, as it can too readily result in knee injuries.
Oh, which school? I attended both Moo U and M go Blue.
