It's always a pleasure to chat with Howard Rheingold who is one of those yodas in education, technology and networks that I've followed for many years. Howard wanting to interview me about some of my work around assessment for the DML Central blog which by the way has some great interviews and posts there you'll want to check out.
You can find the full post there but I thought I'd put the video here in case you wanted to check it out.
