Here's a TEDx talk from Heidi Hayes Jacobs on 21st-century skills and curriculum. I love her idea about "upgrading" our curriculum one assignment, one project, one lesson, one unit at a time. This comes to me via Holly Clark, aka @hollyedtechdiva, at her own blog. (By the way, her blog would definitely be a good one to subscribe to in your RSS reader, to build your PLN!)
