No one is disagreeing with that. But that's not really what's on the table.. which is why some just don't get it. It's not just a 'I'm home, or I'm at school". I encourage you to dig into the discussions going on in your own local school districts to start to understand the challenges they are facing with standards of learning, how to address special needs, disparities in environments, grading, standardized tests (such as AP tests), past work, etc. All these things take changes to accommodate... all these things mean changes to the way things are being ran.. not just day to day, but for the rest of the year. To turn around and say 'oh, nope.. do all this, but we may change it again in a few weeks' is not really practical.
The schools initially had to come up with plans on how to tread water with the uncertainty of return. For most.. that meant 'do nothing' except try to get the online connectivity in place, and deal with school lunches, etc. Then they started to look at the academic issues.. and make changes to try to fit in their new world. Doing so means changing the expectations for the kids AND teachers. That takes time to develop, roll out, and adapt to. Then if you were to try to say 'ok, nope.. we can all go back to normal'... then you have to deal with how do you reconcile all the changes you made inbetween.. and what do you do going forward? Change back to 'normal'?
Imagine just being the kid trying to say "will this be on the test?" let alone the teacher trying to understand what they are allowed to teach or not, what grades will be made from... and then say 'lets just keep evaluating this every few weeks?'
Unless you just want endless churn... it's not practical.
I really encourage people to look into their own local school board discussions if they really think this is just "cleaning the buses and buildings". They need to do some homework.
