My experience is similar to @Raver84, in terms of the quality of home learning. Are the teachers doing videos for their classes and marking work in scotland, and in primary?
We are getting links to YouTube, BBC Bitesize and Twinkl, with some online reading books and a handful of worksheets from other resources. Nothing is being submitted and marked. Class size is 18, and the only differentiation is in the choice of reading book, and they provide two ability levels for some maths worksheets. I'm not complaining - I have been impressed with the variety of the work, and think it's a realistic quantity. I don't expect any more from them at present.
I think that Nicola Sturgeon is making a good point. In some form or other, there will need to be some home learning for many pupils for a while, and teachers and parents need to work out how they can do this in a way that everyone can cope with. Part of that will be coming up with realistic expectations and support for working parents.
If the schools go back too soon, then they will just need to close again. Some parents who are shielding etc will want to keep children home. There will be periods where children and staff need to isolate.
No one wants this, no one would choose it, but there is very little choice here. No point sticking our heads in the sand and pretending that cases aren't going to soar at soon as people start mixing again. They need to be making plans for a worse case scenario where this carries on for a while, rather than reacting to it when it happens.
