There's a very good reason why the originators of this scheme, did not opt to experiment in their own backyard.
As a detailed survey of the OLPC project in Peru has shown, the program does nothing positive for children's education. For poor countries with limited budgets, it is an expensive waste of time.
Imagine the backlash OLPC would have faced if it had tried these experiments in constructionist learning in a suburb of Washington DC and the truth had come out as it has in Peru. The media would have been all over them, every TV network from CNN downwards would have exposed the truth about the operations, and the OLPC would have been forced to shut down.
Indeed, that would have been the experience if the OLPC had tried to implement its program in any major city of a developed country - which is why indigenous children have been the testing ground for OLPC Australia. Far away from the harsh glare of the 24-hour news cycle, people can do what they like and not be found out.
