@lazylinguist anyone would take your view, in your shoes. (And hats off to the pair of you, by the way)
Teaching and lecturing has been traditionally done by assembling students in a building (except where it hasn't, as in Australia's outback, and other places)
The way things were done when Queen Victoria was alive need not be unchanged or unexamined.
Some of us watched the documentary about new style teaching (free on line to the public for some Eton lessons, and in multiple other ways, since Jenny Lee introduced O.U), it was interesting that one rapidly expanding method is costed at £6,000, which is not much above the £5,450 of State secondary schooling .
The firm is private, maximum groups of 15 students, individual careful attention, online of course, and results as you would expect.
Some State schools have rapidly switched to online and phone contact and issuing and marking work online, but others have regrettably not. You will have met excellent systems and heads, and colleagues, but no doubt others, too, who were middling to appalling!
Child mental health has apparently been boosted, away from fear of bullying . The featured private system keeps away from exercise lessons, though online coaching isn't impossible. They reasoned that the sociable side of education is best left to whatever a child chooses, and finds enjoyable or interesting. Pre covid19, and even since, to some extent, hobby and sports groups attended by choice introduce the student to those who are forming a group self-selected as having something in common, and they can switch to, or add on, something else as and when they wish.
