Wow! Now I feel like I am on a roll! Before when I searched for "mobile learning," I got very general explanations of mobile learning, pros and cons, and suggested uses, though helpful, did not address the literature review presentation assignment. But when I made the search specific - specific learner, specific mobile device, I hit the mother-load! For example:
Mcclanahan, B., Williams, K., Kennedy, E., & Tate, S.
(2012). A breakthrough for josh: How use of an iPad facilitated reading
improvement. TechTrends, 56(3), 20-28. doi:10.1007/s11528-012-0572-6
I have found many articles and am now really on the right track. Best of luck to everyone.
