Automatic and Timed breakout rooms
I am volunteering as TEALS teacher at one of the Juniro High schools in Michigan. Teacher shared that it would be great to have Breakout rooms form automatically and split people into equal size teams when possible. Also, add a timer to the breakout rooms so when the time is over everyone joins the main room back without much admin work. They use a product called NewRow which has this feature. She shared that it's a pain point for them in Teams. They use NewRow to teach Computer Programming.
A timed breakout room is an excellent idea - if you provide breakout rooms, a timer of how long would be excellent.
