Here's a quote I find fascinating:
“The current explosion of digital technology not only is changing the way we live and communicate but is rapidly and profoundly altering our brains. Daily exposure to high technology--computers, smart phones, video games, search engines like Google and Yahoo--stimulates brain cell alteration and neurotransmitter release, gradually strengthening new neural pathways in our brains while weakening old ones. Because of the current technological revolution, our brains are evolving right now--at a speed like never before.” ~ Gary Small, iBrain: Surviving the Technological Alteration of the Modern Mind
There are quite a few other recent books about this subject. Another one I'd particularly recommend is The Shallows by Nicholas Carr. There's a great essay by him from The Atlantic that formed the basis of this book. You can find the essay here:

He raises some really fascinating points about how the internet is changing the way we learn and the ways our brains function. His ultimate point is that Google (and computers and the internet) are not making us think less; rather, they are changing the way we think. Likewise, I would say that students don't learn less than they once did; they learn differently.
I didn't grow up with the internet. I didn't have a network connection until I was in college. My brain is being slowly rewired by the internet; however, many of my students have had internet access in their homes as long as they can remember, so their brains were wired (not rewired) by the internet. A question for me, then, is how must I change or adapt my teaching strategies to address my courses to newer generations of students. If newer generations of students learn differently, must I also teach differently?
