Google has helped to fund some middle school buses in Caldwell County, North Carolina with WiFi so that the kids can get some school work done while traveling back and forth to school.
While this is an interesting experiment, the reason behind it is the abysmal state of broadband access in rural America, where whole families have to drive to McDonalds or the local library so mom and pop can get their email and shop, and so the kids can do their homework.
Everywhere I go these days in rural areas, the number one complaint is coming from the mothers of K12 children. Mom is dead tired from trying to manage access to Internet for her children. Stop in a rural McDonalds after 3 PM, and I can almost guarantee you will spot some vans in the parking lot with mom in the drivers seat and two or three kids bent over laptops or tablets trying to get their homework done.
Rural libraries are groaning under the strain of demand for Internet access, and they have to strictly manage time limits on the use of library computers. As the school systems put more and more textbooks and resources online, the problem becomes more acute for families with poor Internet access.
