Thanks for all the responses so far. And I'm talking VERY basic stuff here. Most people I would envision will be as someone mentioned, complete novices and know very little about their camera.
My plan would be to locate the people and 'advance' the session with information useful to them Prior to the hands-on session so our time together would be productive in terms of practical experience. I'm thinking 2-3 people, small group setting would be best.
As far as teaching goes, I'm not a teacher, but my day gig entails a lot of end-to-end process mapping, re-engineering and the like so putting together a basic, understandable outline and agenda that results in learning would be an easy task for me.
Current strategy is what you might call DSLR 101 or Basic Training. Simple stuff like exposure triangle; why we don't use AUTO mode; WB; what a histogram looks like; lots of hands-on shooting examples of what works and what doesn't work and why. It would be like an accelerated learning opportunity compared to learning, or NOT learning on their own.
Since I'm not shooting HS sports anymore, what the heck am I going to do all winter anyway? Might as well help some people get good results from a new DSLR instead of seeing them holding the camera at arms length like a P&S in auto mode and wondering why the output is bad!
More ideas welcome.
