Thanks for the comment Andy. The primary groups we will be working with would be teachers, so adults. Many, perhaps most, already use cell phones which represent a central element in the technology we propose for providing professional development. Other technologies would be used as appropriate to purpose and context. But the most important element in our proposal is that we should pay attention to the quality of experience of children's learning, as well as the provision of schools and appointment of teachers, and that working with teachers on practice in the classroom makes a major impact. We know this from our work elsewhere. Happy to discuss further.
