Not only that, it’s not a solution for every CLASS. Some things are better taught face to face, in groups. Some things can’t be taught remotely with any efficiency.I don't think they should be required. I am an Online teacher, and as much as I love my job, it is definitely not the best solution for every student.
Having said that, I do hope that this spurs upgrades in the technological infrastructure so that it is an OPTION for every student. I also think that having training and practice in this is good for everybody, just in case a similar situation happens again. Heck, just avoiding having to make up snow days at the end of the year would be nice.
But worst case scenario- years or decades of no vaccine, no treatment, and no long-term post-exposure immunity- 30 students per classroom from 9-5 in schools of 3000 students isn‘t going to be sustainable.
