As a school attorney in Ohio, I can tell you why administrators are going to on-line schooling: money.  Schools have to offer a minimum number of instructional days (160 I think it is) and the state allows for a certain number of "calamity days."  If they exceed the number of calamity days (which could be weather, no heat, flu outbreak, etc.), they have to tack days on at the end of the year.  That means extending the teacher contracts, extending the bus driver contracts, etc. and it can create a scheduling nightmare for graduating seniors.  If the school can make up all the instruction days on line, though, then the contracts will not have to be extended.
