Hi Mike, Thanks for informing us of the Bank's intention to revise its Operation Guidelines for Textbooks. Your ideas offer much food for thought. Here in Ghana, we are contemplating similar issues of how best to deliver textbooks to students and ensuring that teachers actually use them in aiding instruction (rather than locking them up in the cupboard) and also how to keep up with ever changing content. Wordreader piloted their kindles here in Ghana, and TESSA (Open University) have been working with teacher training colleges in enabling trainee teachers to access open source materials. Last month, I heard Shwetlena Sabarwal, a World Bank economist, speak at the J-PAL/IPA conference (http://poverty-action.org/Accra_Education_May2012 on her randomized control trial of using kindles in Nigeria. I hope the results from this RCT will continue to inform the discussion.
