Some answers.
I wonder what you instructors do about students who don't listen well or who aren't as teachable as others because they insist on doing their own thing? Or do you not even see this sort of thing?
This happens ALL the time.
For example, some students don't want to make a certain move. Period.
One of the best lessons I ever gave was to a young guy who hit weak under plane hooks.
I fixed him good, he hit it WAY better, straighter, longer, and higher.
Good job, huh?
Not really, he and people he listened to were no fans of slightly upright backswings, and that was a part of the fix.
Never saw him again.
The JOB of the teacher is to try to figure these things out while the adjustments are taking place.
The problem in this and many other examples is simple:
The golfer/student had no problem with the adjustment, his acquaintances did.
And there WILL ALWAYS BE someone who does.
But lots of experience can spot more "I-don't-know-about-this-prescription" doubt than lack of experience can.
At the end of the day, it is a part of teaching.
The more MYSTIQUE the teacher has, the more RESPECT the teacher has, the more the "peanut gallery" buys into a teacher, the more CONVINCING the teacher is, the less doubt in the mind of the student.
You'd think it would be all about getting them to hit it better during the lesson, so they KNOW they can make it work, but there is a lot more to it for some of them then that.
I saw one instructor and told her I was in it for the duration and wanted to take a long-term approach to improvement. I said I wanted a plan. I wanted to know my primary faults and what steps we were going to take to cure them....I videoed my own swing...and showed it to her during the fifth lesson (she had never taped my swing).
She said, "Boy, you really throw that club early."
She had no idea how to correct it, and it was back to showing me the "perfect" position at P3.
I decided to stop paying her and bought Flipper, NSA, and SoftDraw.
Do you hit it better now?
this is sometimes where golf instruction comes up short because of the "hourly" relationship we have with our students.
I agree that seeing a student often and regular is ALWAYS the easiest route for the teacher and the student.
It just isn't always possible.
But, lots of folks just need to know what they need to do, and they improve.
I wish I had a count of how many students I see on the road that tell me they used to be slicers, then bought Never Slice Again, and now they are single digits looking to improve some more.
And I've never even laid an eye on them.
Pretty cool.
Finally I hate to say this but sometimes people just can't learn golf no matter how good the instructor is.
I understand where you are coming from, but I still think Mr. Miyagi was right.
"No such thing as bad student, only bad teacher."
I have to accept that no one can improve my game
I'd love to take a shot at it.
