Worrying about holding the class back
Worrying about being asked questions on the spot
Worrying about their questions being criticized
Worrying about having to work with someone
I've tried to mitigate these things, but I can only mitigate the issues I'm aware of. What else? What am I missing? What can I and other trainers do better?
(yes, eventually I'll compile & curate this, and post it long form)
Even better, word it so 'no' isn't an answer. "What are you working on? What's giving you trouble?" gets better responses than "Do you have any questions?"
But - after a group discussion, follow up with anyone who was silent. They may have things to contribute but were overwhelmed by others more assertive.
Teamwork is important, but you're taking a class for technical content. Someone else's social issues shouldn't impede your learning.
'Separate' them by offering either of them an 'out' to work elsewhere or with someone else.
I've failed at this in the past. :(
"How did you come to that conclusion" deepens the conversation and lets you root cause the misunderstanding. "I think there's a better conclusion" helps too.
It works well for some, but many people don't learn that way. Unrushed focus time lets you fundamentally understand a whole problem instead of trivializing it by seeking out a single quick path through/around it.
Have extra challenges for people who finish quickly. The last few steps of my labs start with "If time permits, repeat but..." or "If time permits, take a deeper look at..."
People who aren't finished and need the time are the last to speak up.
Try "We're going to work on this for X more minutes. Take a break if you need it, but let me know if you'd like me to come help you finish."
If someone takes the time to give feedback, take advantage of it and use it to improve things.
Sometimes, that means asking 'How do i revise my course description so someone like this won't take my class'
I often take pictures of people working in class - but hands and tools only and with permission.
Some conferences try to send photographers in to classrooms for photos. I ask them to leave on behalf of the attendees.
