Although there have always been the "haves" and the "have nots" when it comes to education, I do think the "Digital Divide" increases the gap even more. The extent to which some schools are underfunded in technology is a huge handicap. This, of course, corresponds with economic classes and the amount of local tax applied to each student's education. Some environmental differences are (seemingly) unavoidable, but perhaps it is a question of extremes.
Teachers can be creative in the use of resources, but technology can undoubtedly provide a substantial aid to practicing reading, math, etc. While some students can overcome the obstacles, a greater percentage may slip through the cracks just because budgets for these resources are lacking in their district/school. Perhaps schools need to re-evaluate how funds are allocated and look more at long term cost savings (i.e. e-textbooks). There are no easy answers, but this problem should not be ignored.
