Personally, I don’t understand the argument for part remote/part in person learning. I genuinely don’t see how it reduces the risk.
By having fewer people in the rooms at the same time exposed to each other. Covid is spread by aerosols and most school buildings do not have modern ventilation systems exchanging lots of fresh air into the rooms. If they do, the risk is less if everyone is wearing masks, but they aren't in the schools here.
I do think in person education is valuable, as is remote, which would allow continuity when there are inevitable periods of isolation due to positive tests in the classroom/shared spaces. Whether or not a student tolerates remote learning will be super individual but I do know quite a few who have done much better, but I also have a high proportion of disabled people and autistic parents and kids among my friends. Given one of my friends barely surviving covid brought home by her pre-teen son, I don't want to see that repeated across the country many times over in the next few months. The central government should have put a pot of funds available to help schools prepare, especially in deprived areas, because I do agree they are severely underfunded, as are teachers, and in the current system with no help there is very little that can be done.
