This shouldn't be just because of a pandemic. Kids are dirty. We should be teaching better hygiene to begin with. By the way, hygiene is part of the music TEKS (at least for MS).
2. Class sizes of 12 or fewer
Not going to happen. Period. Schools would need three times the number of teachers they have now and three times the number of rooms. Even if they...
3. Staggered schedules
You would still need more staff and more rooms. Plus, staggering schedules doesn't work when you need change rooms, eat lunch, go to the restroom, fire drills, or any of the other things that make it impossible to social distance. Districts would also need more busses and drivers because even at 1/2 capacity there is no way to spread kids out that much.
4. Younger kids first?
Again, not going to happen. Families with multiple ages of kids (especially if those ages are spread out) would be burdened. Communities are not going to go for that. Plus, can you imagine the resentment among teachers who have to go back to work while others don't? Or, among teachers who get to go back to work while others are furloughed until their grade level starts back. While we are not a "union state" others are and you bet those teacher's unions would be throwing a fit.
5. New calendars
This would mean paying teachers more (remember, we get paid for a certain number of days, but the money is spread out over 12 paychecks). Imagine all teachers on an 11-month contract. District aren't going to go for that.
6. Different attendance policies
With attendance tied to funding, I don't see this happening. Plus, in some schools you'd have kids/parents using this sort of policy as an excuse for their kid not to go to school. With the lack of actual "distance learning" that is going on now (don't believe all the feel good news stories; those are the exception not the rule) this would be a disaster.
7. No assemblies, sports games or parent-teacher conferences
I can see the first one easily. Even concerts, plays, etc might need to be done differently (live stream, recorded). The last one will be hard to eliminate, but is doable with video conferencing technologies such as Zoom, Google Meets, etc. Sports isn't going anywhere. It's just not going to happen, especially the big one: FOOTBALL!! I've said it before, football is a religion in some parts of this state. You aren't going to tell Bubba he isn't going to be able to go the the Friday night pigskin worship duet some illness he "ain't got", at least not without a fight and superintendents have lost jobs and school boards not re-elected over less. Numbers in the stands might be limited, but sports will go on.
8. Remote learning continues
See number six for the main reason this won't work. But, add to that the fact that not every class can be taught remotely, not every kids can learn remotely, and school districts don't trust their teachers to teach this way long term. If this happens, you will see teaching positions eliminated (enter those teachers unions) and there will be a much larger educational divide between the wealthy communities and the poorer ones.
9. Social, emotional and practical help for kids
Kids need this already (I blame reliance on social media and the desire for praise from people they don't even know). However, I don't see this pandemic having a lasting impact upon kids. Going back to school will be an adjustment and it will take some time for them to relearn procedures and "classroom etiquette", but it isn't like they are going to have mental breakdowns in the classroom. If anything, they will treat their return to school as return to "normalcy"
No, I think school will be "different" but also the same. We will come back knowing we will be shutdown again. However, I also think (hope) we will be better prepared for it next time. If the rest of the schools are like mine, they just rushed to gets a plan in place then proceeded to change it every week (heck, they just changed it again this week). I don't think anyone can really predict what will happen come August. Anyone that says they can is just blowing smoke (or smoking something). I can tell you one thing that will happen: everyone's inservice will consist of session regarding how to wear a mask, how to greet students safely, how to maintain social distancing in a class of 35, how to setup Google Classroom, Remind, and other platforms, and how to teach through Zoom or Google Meets. That, I can guarantee.
