No point whining about the reality.
The organizers have clearly worked really hard to replicate this institute as much as possible, with the existing technology and circumstances. We meet from 10:30 to 3:30 -- the late start allows teachers on the West Coast to join at a reasonable time. The materials are housed on Google Classroom, instead of a glossy folder with stapled handouts. All meetings are on Zoom, either in the Brady Bunch grid or the locked-down webinar mode.
Why am I doing this?? Simply because there are too many distractions around me, and the lecture is just lasting too long. The professor broke up his speaking with a "chat window" question every 5-10 minutes or so, which is appreciated. But still this experience is another reminder about the limits of synchronous online learning. No matter how engaging, interesting, personable, etc. we might be ... students can and will still tune out. That's why I continue to prefer the asychronous approach for direct instruction.
