But really what else is there to call it?
Remote learning. It's just like homework, but more of it. It's not home schooling.
As I've already pointed out, nobody, including schools or the department for education, expects you to 'teach', 'school' or 'educate'.
Your children's teachers are still using their expertise to provide explanations, resources and learning activities, in line with their carefully planned curriculum, to improve progress for hundreds of students.
You're being asked to supervise and prod your own two.
Teachers or real home schoolers do both things at once usually; explaining concepts, differentiating for ability, picking up misconceptions, supporting, rephrasing, questioning, extending etc. AND managing behaviour including cajoling the lazy ones who won't try. Even now, teachers are remotely encouraging and engaging.
Why is it so hard for some parents to sit their kids down and let they try for themselves? It's very rare a child can't attempt anything at all. If they get it all wrong, teachers will explain and adapt, maybe pitching slightly differently for it to be accessible independently.
