Reflecting on my work as a tennis coach and what I've picked up from others over the decades:
Helping others help themselves may eventually be the most effective and rewarding way towards acquiring and developing skills.
In contrast, we have the classic lesson concept, in which 1 person tells others what to do.
The receiving party is mostly that, it's some sort of consumption and not much of active seeking, feeling out, questioning etc.
In the extreme, remember the classic non-stop and all-at-once "bend your knees", "take your racquet back", "follow through", etc, etc?
Especially in today's info age in which you have pretty much everything including video demos at your fingertips, maybe it's time to think about changing the paradigm.
If the idea seems somewhat enticing, how to move into that direction?
Maybe it's showing, demo'ing, experimenting, comparing, asking questions - vs an "instruction" of how to do X.
Aligned with the "light the spark" and "keep looking" principles here.
Imagine there's a group and the instructor doesn't show up - what do they do? Or if they want to practice some more by themselves?
So it might make sense to introduce basic "help yourself" and "help others" concepts early on. They don't need to be perfect, just good enough to get started and then iterated and built upon.
This would mostly be around 1) identifying what to work on, 2) finding a possible path, and 3) repetitions incl variations.
For
1) you can help your students identify 2-5 things to work on.
2) introduce ways to look and try.
3) teach how to teach - core elements and skills for a basic lesson? See e.g. /train-others.
Maybe you create the next group of coaches - which again will help others help themselves. Must be the first positive ponzi scheme in history :P
