My grandchildren spend about four hours each day on their schoolwork. Their teachers are available the whole time to answer questions by email. They have one or two zoom type meetings each day with the whole class.

A Catholic school nearby uses a Zoom type classroom with the teacher and the kids working together the whole school day.

Some places teachers may be doing very little but in some places teachers are doing a great deal.

That sounds pretty good.
I get a feeling the quality is highly variable.
