Ironically enough in the same week, I subscribed to Edweek, my sister-in-law was interviewed by them on P16 stuff, and then I myself was interviewed for an article on email in schools. I had a lot more to say (isn't that a surprise if you know me) about this topic, but I think Katie did a nice job with an overview of some of the issues and uses. My bottom line is that either we teach kids to use these tools in an appropriate context or we will have to prepare for a slew of other problems resulting from miseducation (or noneducation) about technology. I'm increasingly concerned about school districts who lock down tools and resources in the name of protecting students; they should be looking at how to manage tools and resources effectively in my opinion.
Anyway, my sister-in-law's piece should be published in August or Septmember, I think, and I'll post the link here when it's available.
