What good is having a school with a lab for students to use when there's a covid outbreak that caused the school to go virtual? If the school has enough staff and students out to make them go virtual then the last place those kids should be is in the school building around other kids. Under normal circumstances sure many schools have computer labs you're totally right though not all are available for long enough to do school assignments.
A lot of places don't have the same access. Even in my area the school district was renting out hot spots to students last year and we live in the wealthiest county in the state. My governor last year put a plan in place to get broadband internet to more places throughout the state..broadband, consider how slow that can be but it's better than nothing. Even the libraries..our libraries in my county get a budget of $20+million a year just for one system..certainty not the case all over the state where libraries may be fewer and farther between and have less amenities or even open much. Library locations close down too due to exposure. How will students get to those libraries when the parent is working and the kid is sent home for virtual learning due to covid? And who will be supervising them? Snow days suck they do from a parental standpoint but trying to ensure your kid is actually doing school lessons during that time was a lot of stress to a lot of parents and quite frankly a good portion just couldn't simply attend--a lot of statistics on that. Unfortunately at least in my state minorities ended up missing a significant portion of school days when the schools were under virtual learning and there were a variety of reasons for that. By missing school days I mean they just didn't log into their school system or turn in assignments in greater numbers.
What happened last year was a hodgepodge of things that no one knew how they would turn out. It was never a permanent fix. A lot of areas just don't have the capacity to continue doing what they were never designed to do. It's one reason why the school district my house is in created their own online school so parents whose kids did better that way or whose parents who were very concerned about in-person had an option that was still connected to the school, however they advised what it was like last year wasn't going to happen, it was going to be actual school going on.
What the PP mentioned was going remote for several weeks. But even in your comment it was the kid who doesn't have internet access gets the assignment the next day, well when is that when it comes to covid? And does that put the student behind? What about where the other students are at, does that mean the student who got their assignment late and has 3 days to complete is now a good portion behind the other students? Sounds like it would be a pain for the teachers though.
I can understand why other areas do things a certain way but I also understand why virtual isn't treated the same as in-person in other areas. For many the quality of education, the type of education, the means to even get that education all of which can be internet access, teachers to teach the lesson, website issues, assistance a student needed, etc just isn't as workable for them. I mean we have a lot of online schools out there that were designed for this sort of thing. If you didn't have reliable internet, transportation to get to one, supervision while doing school work and your student didn't do well online learning you probably wouldn't enroll them in that. It's really whatever an area can handle. I do think at least in my state it was good when a while back the added flexibility of doing a minimum number of hours instead of just straight days helped (this was all long before the pandemic was around). To make up snow days at least in my area schools may add minutes or hours to the day for X number of days. On the surface that may not seem like much but it's probably better than abandoning certain lessons if there's too many snow days. I seem to remember it helping in some of my classes and not being much of a bonus in other classes. Years back they added in admin days where the students were off but the teachers and others were in, they rely on those days too so students would just go to school instead of being off school. I don't know how TN treats required in-person instruction time on that though.
