The educational system certainly developed this learn at home model on the fly and kudos to them for attempting to do so. Certainly no easy feat considering all the different dynamics at play, including funding for test scores or lack there of.
The teachers initially in our District where very hard core and if a kid missed an assignment would send the parent an email making them feel less than. One of my oldest's teachers even indicated "she was concerned". Mind you this all C or NC and has no bearing on her going to 6th grade. Since then they have gradually eased up on the expectations and while the send out progress reports I think they realize parents and their kids will only complete what they can.
I think the Districts made a big assumption that every parent is going to be home working and spending all day long with their kid engaging in home school family time. That is not the case! I work more hours now that I ever did at the office.
