My frustration with the teaching pros I've worked with is a lack of direction for practice following lessons. I'm sure the good ones will structure specific practice sessions. x number of balls with drill #1, y number of balls with drill # 2, etc. My last two local pros, I've asked them both specifically for that guidance and they don't seem able or willing to provide it. Frustrating. Before that I'd tried lessons with 3 different pros as I was first learning and, frankly, didn't know enough to ask for that guidance, but it wasn't volunteered. So, 0 for 5 with what seems to me like a basic requirement for student improvement.
I look at the range at my club and almost no one (less than 5%) is doing any sort of drills. All just beating balls. Interestingly, it is the lower handicappers who are doing drill work. Chicken or the egg, eh? Are they lower because they do drill work, or are lower handicappers more apt to do drill work?
I think a pro needs to figure out when you are next coming for a lesson, and provide specific practice instruction and templates based on what your schedule permits. That has the pro and the student invested and probably makes for a more profitable and successful endeavor. Probably more enjoyable for the pro too.
