Schools should close to stop the virus spreading.
Teachers are much more skilled at providing online lessons using programs like Seesaw, Google classroom etc. to provide online teaching than they were at first. At least if schools are closed, they are not trying to juggle 3 types of provision as described by geekesse.
No problem if parents can’t work, because they need to stay home and do childcare so have no money coming in and businesses close.
No problem if children don’t have access to the facilities to do online work and parents aren’t able to help them even if they do have enough online access for all the children in the family. My DD called me for help with things like the nth term, or identifying sequences like 1,3,6,10. My DGD could complete the sequence, but the question asked what was it called. Do you remember conversion between fractions, percentages and decimals?
A lot of the terms in English weren’t in vogue when we, or even our children were at school, so faced with an exercise on modal verbs, determiners, past progressive or fronted adverbials . . .
I’m glad I’m not in charge of making decisions, and I think schools should close - except they won’t. They’ll still have to be open for children with SEN and children of key workers just like they were before. Has anyone told the virus not to attach itself to those children?
What ever the decision, people won’t be happy, but they might be alive to grumble.
