So, are ski instructors paying attention, retooling, and revising their values?
Not everyone wants to carve all day.
Many people want to ski the back bowls and play in the trees, moguls, crust, slab and chutes.
They need to be able to skid, scarve, tip, and use rotary and steering forces as well as knowing how to carve.
They want to huck and play in the park and pipe.
They want to ski backwards.
They want to ski fatties, twinntips and reverse camber skis.
They even want to ride snowboards some of the time.
Many of these will never be part of the instructor's milieu--and considering the number of people acquiring these skills-there is no real need to make them part of the standard group lesson. Legions of skiers are developing these sort of skills without formal instruction.
However, the basic ski turning mechanics and advanced levels of skier balance, which undergird all skiing are still very much in the instructor's purview. And, the basic carved turn (brushed, drifted, railed, rotated, whatever) is still the bread and butter of skiing, and skill acquisition. Throw in a few 'toolbox' skills (side slipping, hop turning, kick-turns etc) and you have plenty of valuable material for the instructor to master and teach.
It has never been the case that the ski school instructor is the end all and be all for every movement people might want to perform on a pair of skis. I would bet that most posters here who ski fatties well, huck, drift, butter, or ski switch well didn't learn how to do these movements from a ski school lesson. But many (either as kids or adults) learned the basics of turning a ski from an instructor or race coach.
Nolo's complaint that no one wants to carve anymore is offset by the reality that no one wants to take lessons on skiing backwards...those who want to ski switch will just start skiing switch with their buds and figure it out. And there are Park specific courses, and even the rarified, high-end specialty clinic on the elements of extreme skiing.
Don't tell your students you're teaching them 'carving'. Just tell them your teaching 'skiing'.
