A new addition to the coaching toolkit, perhaps — not quite instruction or demonstration, but not “guided discovery”, either — learner rehearsal.
Not enough, in my experience. Still tends to be “do it this way”; “no, put you top hand here, and your foot here”. We still too often coach with an “ideal technique” in mind — the “eye test” — the player who “looks right” (i.e. is closest to an ideal) is rated most highly.
