whatdoibelieve: I'm a retired HS science teacher...
During the last few years of my career I ran technology for the school.
I'm interested in having a teacher-to-teacher exchange regarding LMS issues.

Thanks very much for this post! As an ex-teacher I've been following this issue, and this is the best summary I've seen about the challenges of K12 remote teaching.
