Here's my experience from teaching in person this summer. Summary: if you have access to the outside, buy a fan (note: avoid pointing airflow from student-to-downwind student). Second half of the video shares my experience teaching to an in-person group along with an online remote group of students at the same time, including use of an Owl (360 degree classroom camera, which is nice to have but less useful than the other things in the video, having a 2nd display like a TV to display Zoom at all times is so much more useful). One tip I forgot to add is getting the kids on Zoom to get used to speaking out loud to share, hard for people in-class to see they've raised their hands or posted to chat, though I do assign kids to monitor these.

(I use cotton mask because I want to wash and reuse mine, but surgical of KN95/N95 are far safer)
