Great question!
For classes with group work, I’ll pair synchronous students together in a breakout room and they can check in with me through the chat feature as needed. I’ve also physically left the classroom to go into the hall and video chat with the synchronous students on my phone.
If there’s only one synchronous student, I check to see what their comfort is with joining an in-person group via speakerphone or WhatsApp video chat, which they’ve always been okay with.
For asynchronous students, I provide various suggestions e.g. pair up with another asynchronous student, ask someone in their household to help if possible, email me and request a meeting. Depending on the activity, I’ve had asynchronous students upload video/audio/text of their activity, even if it was done solo which we then circleback to as a class.
Finally, for asynchronous students, I make sure to summarize key discussion points from the breakout groups and/or ask students to reinact what they did so it can be recorded for all.
