It will be year 3 of covid and this is 100% the fault of the same people who have created every other problem in the education system: the administrators. There is no perfect way to open schools, that much is certain after looking at other countries. But looking at the state of things, it doesn’t even seem like people are trying. Japan has students come in on alternate days, so that the school can operate at 50% capa…
I don't fault any schools for struggling from March 2020 to June 2020, being thrown into the pandemic and remote learning with no warning. But I was absolutely astonished to see that most administrators took the summer of 2020 off, assuming that everybody would be back in school that fall and things would be normal. They wasted several months of time that could've been spent planning contingencies and how remote lear…
Seems like a human solution to a (mostly) technical problem. Basically you just need a way for students to mark a message as hand-raising (and maybe a way to point out another student's message), a chat filter for the teacher to read those messages, and a USB LED (or some such) to act as a raised hand until the messages are marked as read. Of course there are some edge cases, like temporarily ignoring a child who's repeatedly raising their hand to troll, but this still seems like it could've easily been usable by the start of fall 2020.
You'd likely still need a surrogate for young children and special ed students, but you could probably eliminate ~2/3rds of them (? I'm not sure how old children need to be before they can be expected to remember they need to mark their messages & how to do so)
