The photo would lead you to believe the focus of the research is K-5, but in fact it is K-12. The research results are quite interesting - at the very least thought provoking and good reason to thoughtfully examine the real goals of each technology initiative.  From Pearson Schools:

Teaching in a Digital Age

How are your fellow teachers using technology in the classroom? School districts have more access to technology than ever before. Many have made major investments in education technology to engage, motivate, and personalize learning for students. Games and mobile apps have the potential to transform learning in ways unreachable with pencil and paper. But, as teachers know, incorporating technology isn't easy or simple.
