I agree with BelleSausage
Blended learning needed time, training and extra resources, but the pay off would have been that schools were safer and more likely to be open now. I did not ever understand the logic of university classes being cancelled entirely and moving to Zoom but pupils just a year younger and teachers were mixing more or less freely.
That said, I know that both my DC (one S6 and the other primary age) benefited enormously from being back in school and their teachers have done an excellent job. I suspect, however, that the teachers have been given no additional training or resources for online learning and I question why, given that blended learning was supposedly the contingency, it is not being put in place now.
I am a single, working parent, and having DC in school 33-40% of the time with a structured programme for the rest of the time would be an awful lot easier than being left with what now appears to be an open-ended school closure with no plan. Our LA has just written out about online learning from 11 January (extra holiday until then), no mention of returning.
I totally understand that it has been and would be better for DC to be in school full-time. But in the absence of blended learning, they are actually not going to be in at all. Or at least I will be surprised if they return on the 18th.
