I whole-heartedly agree with the excellent points made by Mr. Summers. A major obstacle to moving to this next phase in education, however, is the cost of providing every student with high-speed Internet access and a computing device capable of video and interactive textbooks.
Fortunately, the combination of mesh networking and Android provides a wonderful solution to this problem. I've been working on the "Digital Divide" issue for over six years and have finally found a model I believe will work, called eCommUnity (http://www.e-comm-unity.org
). We're planning a pilot project in Charleston, SC and hope to attract interest and funding with a successful pilot. If all goes well, we hope to eventually help schools implement the recommendations made by Mr. Summers and many others in the education sector (e.g., Salman Khan and others).
