I’m an international teacher (recently was in UK though) and my experience echoes those who mentioned international schools above. Ours is not a private school but the understanding was from the very beginning that we needed to provide some sort of meaningful, interactive teaching to our students. We had a plan from Y1 up to use google classroom live, but in the end our youngest (up to y4) never stopped attending. It worked absolutely fine, it wasn’t as good as face to face teaching, no one suggested it could be, but we did a tech audit with our children and pretty much everyone had access to at least a smartphone that they could use to access the online material, we offered those who wanted to the opportunity to borrow chromebooks from the school but actually very few did.
We got better at using classroom as time went on, but the many safeguarding shouts that seem to come from U.K. teachers really seem to be of negligible risk using classroom, no one can join unless they are in the class, all meetings can be recorded start to end, children don’t have to turn on their cameras. Teachers can choose to or choose just to present behind a PowerPoint or other presented material. I liked to be visible but that was my choice. On another thread I was accused of just “lecturing” the children and there was generally a huge amount of defensiveness from U.K. teachers who seem to have the attitude of “this is not what we do so it’s impossible”.
We supplied a big bundle of material to each student before we shut down, we had been gathering it for a week and had scoured the schemes of work to get it all together- of course somethings got missed but hours of preparation before we went off meant they had most of what we needed them to and so we didn’t have to ask them to print everything out.
Once in a lesson we would do a whole class introduction and then split them into groups of five or so to work on differentiated material, I visited every group in term to teach, guide, facilitate etc (it was lovely to join a conversation and hear them all discussing whatever we were doing) they also knew their “rooms” (where the small groups were) were being recorded so any issues could be addressed if necessary. We are back at school now and the feedback from parents and children has been overwhelmingly positive.
I am not suggesting this is the best or the only way to make online learning work but it did work for us and the majority of issues with it raised by U.K. teachers were possible to deal with. As for my own dc, the little one has his preschool every other day (so they could halve class sizes) but otherwise watched too much tv and dd (7) was doing a similar online programme with her own teacher so apart from occasional tech help, she was self- sufficient.
