A THUMBING RULE: Don't conflate "digital natives" with tech-savvy, says John Merrow of Learning Matters. Just because kids are multi-tasking on snazzy devices doesn't mean they're using them productively. He observes there's a "1-9-90" rule of thumb: 1% use today's technology to create, 9% focus on curating and critiquing, and a disappointing 90% just consume.
