Schools are doing all they can to teach kids at home. And since so many kids have iPhones and tablets the switch doesn’t seem that severe.
I don’t know if they still dissect frogs in Biology like when I was that age, but just about every subject can be taught at home.
What you can’t replicate at home is the social interaction- eating lunch, playing sports, going to the prom.
I feel bad for my niece. Every year the 8th grade takes a class trip to Washington DC, to see all the monuments, the Smithsonian, that whole deal. They’ve been fundraising all year, and they had to shelf it.
