When I have Zoom classes I still try to have students collaborate to answer conceptual questions.
Just as in class, it is hard to get some to speak out.
I tell students, "I am muting myself now so you can discuss this question among yourselves and come up with a response."
I have found that if I don't mute myself, they seem to wait for me to answer as if I had asked a rhetorical question.
This makes it clear to them that it is THEIR turn.
If I have enough students online, I use the Zoom "Breakout Rooms" feature and put them into small groups to collaborate.
I can then "visit" each room in turn, just as if I was circulating through the classroom and they are working in groups.
