Our second "Mathcast" created by a team of sixth grade students at our school is embedded below. My wife is our new sixth grade teacher and I'm impressed with her willingness to deploy teaching strategies like this (and she also is using a variation of Darren Kuropatwa's student scribe post method). Our first published mathcast from two weeks ago has over 200 views already on YouTube, proving once again, that the Internet is the most poweful publishing platform that our classrooms have ever seen (if this video was published on a DVD it would be luck to be played 10 times).
This is only the second mathcast and I can't wait to see the clever and creative strategies that the students use in the future for these videos! Kudos to our youth mathcasters!
