My daughter who was “home schooled over the phone” as you have dubbed it was listening to her teaches teaching class on the same schedule as in person. They prepared and taught, while managing their own kids, and should definitely be paid for it. Additionally, they prepared weeks worth of sources/handouts and we picked them up from the parking lot, exchanging it for homework and tests.
Almost every packet contained a treat and a project. I was thoroughly surprised and impressed.
My sons yeshivas did english on zoom or through the same portal they used in yeshiva. Other sons yeshivos gave shiur by phone and they had chavrusas by phone as well.
Pretty good for disorganized archaic inflexible orthodox people, no?
