I don’t want one - but I think if there is one - keeping schools fully open is nuts!
My plan for future lockdowns (as a mere school teacher):
I’d say 6th forms, collages and unis fully virtual (bar labs, practicals ect in uni that cannot be postponed which should be done in small bubbles)
Secondary closed to most pupils, virtual learning with on site access to vulnerable/key workers who need childcare. These use school site to access same online provision (or additional buildings eg libraries/church halls if required to maintain social distancing at all times). Staffed by support staff or teachers with reduced virtual teaching load (so when in school covering they are not expected to be teaching virtually though they could probably email ect). All staff who are vulnerable are wfh only.
Huge pot of money for schools to enable virtual learning successful!
Primaries to stay open initially. Bubbles of 1 class only. Government pay for cleaners to be there all day. Again all shielding staff to wfh (potentially virtually teaching classes in school or helping to teach any children out of school due to shielding/isolation).
If situation is deemed necessary - move to a half class approach at schools, where the class is split and gets half a week in class socially distanced from teacher (properly) and half a week accessing alternative provision (this could be external providers coming onto school site if space, within the local community I.e. church halls, leisure centres) sort of like a holiday club approach with educational basis.
