Schools have been playing the computers in the classroom game for over 30 years now, using software that is often on equivalent to interactive textbooks. Yet there has been no concrete evidence that computers improve the quality of education, especially with large deployments. Heck, very few teachers even know how to incorporate computers into instruction and the little advice that they do receive often comes on ideological grounds (e.g. the "constructionists") or from vendors (who simply have a product to sell).
