Dr. Jean M. Twenge's book iGen.
Filled with charts, statistics, and facts, her book, will amaze you at how iGens have moved beyond the technology and social media we think the Millennials own.
Here is a link to the many Appendices that supplement the book, and along with the book, here is where you will get a quick sample of what the author has compiled to help readers understand the iGen generation. Ironically, when you view this link, the first graph you will see is Figure 1.A. "8th and 10th graders' print media use." Hang on to your seat when you view this graph.
Coincidentally, NYTimes columnist Frank Bruni quoted Twenge in his Sunday Review column last Sunday, [She said] "Having to sit for more than a half hour or an hour doing one thing — that's gone by the wayside, and that concerns me as an educator and as a parent."
Here is one more link to her TEDx Talk. In her closing comment she states, "Let your phone be a tool you use, not a tool that uses you."
