It's five minutes before the bell. My psychology students are reaching for their smartphones after our mini-field trip to the main campus library for an introduction to online reference materials.
"Wait," I say. "Before you go, I have a short question to leave you with."
The students sigh but smile, setting down their phones.
"What's left?" I ask, pausing for effect. "What is left?" They wait for me to continue. "Online, you've now got instant access to what everyone everywhere knows and thinks. In the past, to know anything you would have had to spend hours finding and memorizing it. Now it's right there on your smartphones. So what's left? If everyone has access to all this information, what is school for, and how could it possibly give you any kind of edge? What's the future of education?"
