I think that we should be looking at a way to mobilise volunteers to put together materials to support home learning for schools, right now. I am thinking of support tailored around the schools' curriculum, that would support both the pupils and the staff. I think you need teachers (and criminal checks and safeguarding) in any real time interaction with the pupils. However, I am thinking that pre-recorded videos and extension work, tailored to the needs of the course, might well be something that retired/ trainee teachers/ graduate parents/ retired university staff etc. might be able to help with. Also, if schools teamed up to work together on course materials, they might stop duplicating some of the work, and end up with really good resources that could be widely shared.
My DS goes to a state school where they are probably setting quite challenging work, but there's no reason why resources couldn't be created, maybe together, and shared across schools, for kids who are able/ interested.
I am finding it a bit galling to read all this "oh aren't private schools so wonderful, they have their pupils on zoom from 8 till 6, they have such an advantage. " Well, it's great if this suits some schools and some pupils. However there are a LOT of advantages to asynchronous learning.
I think we haven't started to tap the potential of the internet for good in teaching and education and covid could be an excellent opportunity.
I also have a vested interest of course in that we've been shielding. We have loads of A levels and degrees in this house as it happens and have taught at Uni level, so are well equipped to teach for home schooling. But I don't want my son to lose his school place for good and I also would be really happy to help in this situation if I can.
