The Innosight Institute is releasing case studies of online education. Note that the Innosight team is behind the book "Disrupting Class". The first case study they released is on the Alpine School District in
I found it fascinating from a number of different points. The first is to see a school district striving to meet the needs of home-school parents by marketing a product that they want. How many school districts use business-like responses to issues affecting student enrollment? Second, it is pretty fascinating to see how quickly they are able to get a virtual high school up and running (with K12 Inc). Third is that virtual schools really can save a considerable amount of money and still get results.
Innosight says that more case studies will be released quarterly and I hope so. It is a great primer on the online education market and should help further the cause.
