Please bear in mind that although teachers are supposed to provide online learning for their students, that much of the time I would go in at 7:30, start prepping for the day, check who was in my lessons, set work for those at home, print out for the day, print out for all the teachers who were absent and had sent work in, deliver their printed work all over the site, then start teaching 6 lessons, with a break duty, half lunch duty and after school revision.
Meanwhile, between my preparation and the lesson itself, some of the students who were isolating would test negative (or have a relative test negative) and be coming in, and half the students who were in would go home. I would end up having set work at home for students who were in school and having half a class missing when I thought I would have a full class.
I am sure I must have missed setting work for some students as it was simply so chaotic. Setting work that is accessible at home is not simply sending home a powerpoint we are covering in class. It requires entirely different material preparing. When half a class went down, they got work. When an odd student was off, they may have been missed. There are only so many hours in the day.
Meanwhile, I would say about 10% of the work I spent hours setting and sourcing to make it actually accessible at home got done.
Honestly, from my perspective, the limitation on home learning is the learning side, not the teaching side. You would think from Mumsnet that there were armies of kids, all desperately waiting for work to be set whilst the lazy teachers let them down, when in fact, my experience, what you actually have is teachers running themselves ragged trying to provide 3 types of lesson at the same time (school, online, home hardcopy) into a void from which very little was ever actually returned.
