Harris I totally agree! And my DD would not want to wear a mask..indeed tried to resist seating in rows for 6 yr olds. If they are in the same small room for 3 hours at a time a row or around a table will make little difference.
It would help if the children could be taken outside a few times a day - maybe every hour - and the rooms are well-ventilated. Facing each or in rows might make a marginal difference. It might also discourage chatting.
Secondary schools face much bigger problems because year groups usually have several hundred pupils and options and setting means that they can't stay within a bubble of 30. The pupils are also physically bigger, so there is less circulating air and they are closer together than in primary schools. The teachers and TAs have to move between bubbles.
All the modelling and promises before schools re-opened fully was done in primary schools before the summer holidays when very few schools had full classrooms.
Everybody agreed it was important that education resumed, but the decision makers just stuck their heads in the sand, shrugged their shoulders, stuck their fingers in their ears and hoped for the best. They ignored calls for blended learning, which would have allowed for a combination of online and face-to-face learning, which would have allowed for smaller classes. That would have cost money because it would have involved ensuring that all pupils had online access at home and actual support (maybe the money which is supposed to be spent on catch-up tutors) for those who weren't engaging. Ironically, that's what is very possibly going to happen anyway - but too late.
