Mark Wagner of the excellent EdTechLife blog is pretty much on fire at the moment (metaphorically speaking of course). Not only has he produced three presentations for the K12 Online Conference, as well as wikis on various subjects relating to some training he’s been doing but his post for Infinite Thinking Machine on 21st Century Skills and the Infinite World of Information contains more useful links than you can shake a stick at. Oh, and he’s currently finishing off his PhD as well. What a guy!

There are an AMAZING number of links on that ITM blog post– WOW. I was impressed to see that Mark was signed up for three presos, he is sharing some great stuff!
