...But even if he makes that fundamental paradigm shift to offensive intent ("go that way," instead of "stop going this way;" glide, not brake, control direction, not speed), the "advice" he's been given will hold him back--literally. For one thing, pressing the tongue of the boot is NOT how you "get forward"--it's actually how you push yourself back!
Second, and related, since you are describing the transition/beginning of the turn (you referred to the "new" inside ski), I would ask you to challenge your belief that flexing the ankles (dorsiflexing, "raising the toes") and pressing on the tongues of the boots is what you really want here anyway. That he "understands these concepts" actually suggests a fatal misunderstanding of what happens in good turn transitions, in my opinion, and that would help explain why he has trouble applying them.
Yes, we need to move forward into turns. But this is perhaps the most misunderstood movement in skiing! "Forward" is not
the direction the skis point in the transition. It's toward the inside of the new turn--downhill, in the direction you're actually trying to go.
Transitions are where the "crossover" or "crossunder" occur, and the body and skis must travel in different directions. The activities you describe (dorsiflex the ankles and press on the boot tongues) at best cause your body to move "forward" in the same direction that the skis point, conflicting with the crossover movement.
I suggest that the "correct" movement in the transition is exactly the opposite of what you have described. "Open" (extend) your ankles and get off your boot tongues here! Let your feet move "forward" beneath your body.
Consider that, in linked turns on smooth snow, your feet and skis always go faster than you do (they take a longer line than your center of mass). That means that, in the transition, you have to let your feet literally come from behind and pass you, while "you" take a beeline shortcut to the inside of the new turn. Remember too that your edges are disengaged and unpressured at the beginning of a turn, so the conventional wisdom that we need to press down on the tips to engage them here is a myth.
You cannot, of course, both release the edge and
engage the tip (or any other part of the edge) at the same time. Rather than worrying about how to pressure the skis in this light, unpressured "float" phase, focus instead on setting yourself up to be in the right place for balance and accurate edging later in the turn, when you reengage your edges. It's not until the edges are reengaged with sufficient pressure to bend them into reverse camber and carve--somewhat later in the turn--that you actualy have to be "forward" on your skis (and even here, "forward" refers more to your motion, not your position).
Ironically, the only way to get "forward" as the skis carve through the pressured part of the turn is to allow your feet to get ahead of you in the transition! This move, that makes great skiers often appear to be "in the back seat" in the transition, is the well-kept and little understood secret of their constant forward motion. We discussed it at length here last spring, but it's worth bringing up again. It's what's happening in these animated images: Note the dramatic movement of the feet and skis forward beneath the hips in these transitions.

Here's French slalom ace Laure Pequegnot, in a winning slalom run a few years ago:
And Jimmy Cochran, training at Keystone last fall:
The move is very obvious in these (and many other) great Ron LeMaster montages (www.ronlemaster.com
Finally, a sequence of me, showing the diverging paths of the feet and CM. It's a little hard to see, perhaps, but my feet have moved "ahead" of my hips most dramatically in the third and fourth frames, but by the time I reestablish pressure on them, I'm solidly over my feet and the sweet spot of my skis, and driving "forward" down the hill:
Once he's got the GO! Factor, we'll address some of the particular movements that will make his turns even better, and especially the misunderstanding described above that I believe may be causing problems. Contrary to common belief, we'll explore balancing more over the heels in the transition, getting off
the boot tongues, letting the feet get ahead of the hips for a moment, even pressing on the backs
of the boot cuffs for a few turns. We'll explore the irony that being
forward actually prevents moving
forward. Heresy, you say? Don't knock it if you haven't tried it!
And THEN we'll go get that NASTAR gold!
