Ok, here it is. I'll put my teaching on up for critique, if not my own skiing. Here's the video of a 12 yo non-athlete on her first day skiing. She is on very small bunny hill, this is her forth run ever. On another thread I incorrectly identified the names of the skills I practiced with her, but whatever this is, I'm impressed how a few instructions gave this result.
She had a first time down the hill to get a taste of the concepts of edge release by side slipping, and the effect of shifting weight fore and aft. Nothing great resulted, just introducing her mind and muscles to the concept of edges and weight distribution. Then a run to release and set both edges during a slow traverse.
The video is her fourth run. She was simply told to keep even slight pressure on the tongues of her boots by leaning a bit forward, and steer by tipping her inside ski a little. The next run she was told to flatten her skis for a second between turns before tipping the new inside ski, but not to twist, let the skis turn, and she did the same run with less wavering in to the brief stem position shown in the first turn of the video. In a few more tries she was told to release her edges a bit by tipping the other way slightly in the last part of the turn and she was able to control her speed some and make more confident turns around obstacles. All in all a one hour lesson and she could get down the hill with just a few instructions. So I don't think this is the PMTS teaching sequence, but does this look like this is a reasonable way to start teaching good technique?
