Hands on. Give me the stuff, let me work it. Best way to learn is to do.
Let me break it. Whatever it is, I want to learn the limits.
Can I eat it?
Do I need to or May I bring my own tools?
Rather than sit in an uncomfortable chair and be lulled to sleep by a monotone speaker in an unventilated room I would prefer to be mobile, interact with the people taking the
course, and be able to lift/move/bend/break/tweak/electrify/explode/burn/eat whatever it is I'm working with.
And don't give me donuts, just REALLY STRONG coffee. I'll bring my own lunch.
Nothing I hate more than some guy in a white shirt and tie telling me "Please put down and extinguish the display."
The first part of
workshop is WORK. I want to work with the thing. Let me get involved, take the thing apart, look at it from whatever perspective I'm coming from. Remove any and all limits, and be sure to have a backup available after I destroy your prototype, in case I want to try doing something else to it.
If you are having a workshop on scythes, do it in an overgrown field not a classroom. The setting needs to fit the operation of the device/tool/project/concept. Classrooms are cages.
