The issue is actually with the government, not schools or teachers. The DfE should have given clear guidance on the expectations of schools about nationwide education provision during this time, but they didn't.
It would have been so easy for them to say 'The curriculum is suspended. Treat the next 4 weeks as extended holiday, we will have in a place a virtual national academy after the Easter holidays and from that point on schools will be required to also do x, y and z'
This would have led to consistent, centralised provision up and down the country. Instead you have schools all doing their own thing as SLT publish internal policies about what teachers should be doing which ranges from teaching a full online timetable while rewriting schemes of work and undertaking CPD to posting links to online resources once a week. The misapprehension is that a teacher has made their own decision about which of those two routes, or anything in between, they are following.
We have so little autonomy over how to act in this time and everyone seems so quick to criticise but we get hauled over hot coals for stepping away from internal policy because of the consistency culture. Even if I want to, I cannot provide more for my students than my colleagues, because this would be inconsistent. If I persisted in going against the wishes of my SLT, my pay could be affected and potentially my job security too.
Large scale decisions aren't made by individual teachers like they aren't made by individual nurses or police officers. Its centralised at DfE level or, failing that, from SLT.
I wish the government had put more emphasis on the fact the curriculum is suspended. Nobody should be trying to wfh and teach a full timetable. Any educational materials should be a review of concepts already covered to promote fluency and independence and avoid widening the gap between more and less privileged children as we cannot guarantee the same level of access or support available to them at home.
As other teachers have said, if you have concerns about what is being provided for you child, email the school directly, but do bear in mind that whatever you send in, there is at least one other parent emailing and asking for the opposite.
