My wife works for one of the better districts in our state. I can assure you that NO district has a plan or the ability to hold ANY offsite classes.
As for teleconferencing? How many people that actually produce something besides paperwork can “phone it in” all day?
Yep...how does Bob the Builder phone it in?
Washington Connections Academy
Fantastic wonderful digital school.
Anybody and everybody can "teleschool" now, as long as they have an internet connection. See "Khan Academy". I'm sure there are others, but KA is at the forefront.
Teleschooling is inevitable. Future on-site schools will be limited to lab, shop, band, sports, and similar activities, and perhaps tutoring.
