I think it's ridiculous if they're planning on reopening physically right now. It's dangerous for students (mostly older students, who are at a lesser risk but still at risk depending on their health), for teachers, and if children become carriers, it can be dangerous for the parents/grandparents/guardians. Too much is resting on "it depends" right now to safely say.
Also, I can never get a good read on the numbers. Yeah, case numbers are high, but death rates are relatively low. Also, there's been issues with hospitals labeling deaths as being "due to complications with covid" when the death is not related to covid at all. But either way, there's no denying that folks are dying from this virus and it should be taken seriously...and what I know is that it's impossible for students to do the two major things they need to do during this pandemic: social distance and being cleanly (let's face it. folks nasty, bruh).
So far in my city, they've opted not to return to school physically. I don't know fully what public schools will do, but my co-worker's son's charter school (high school) is giving every student a laptop. They are required to be in front of that laptop for lessons from 7:30A to 3:30P (cameras on), with lunch break and bathroom breaks. The school will also provide lunch (though you have to come and get it and then return home). They are also planning to enlarge the classrooms and make teachers rotate rather than have students switch classes.
BUT ALSO! One cannot ignore the need for schools to be opened (much as I complained above). Why? Lower income families and students who attend schools in lower income areas. All schools don't have access to funds that can get them the tech they need to have school remotely. All homes do not have access to wi-fi. It's not feasible that students in lower income areas will have the same sort of access to education as others in mid-to-higher income areas (and that's something that has ALWAYS been the case, so it's multiplied now). But a teacher said, "You can catch 'em up, but you can't give 'em their lives back." I guess that will have to be the case.
