I just found out about a free resource that I think would go great with a Discovery video.  CoverItLive.com is a live blogging site.  Live blogging is where comments are posted to a blog while an event is going on.  It is used to cover sporting events, speeches and other news worthy events.  However never let it be said that a teacher won’t re-purpose a Web 2.0 tool for their own classroom.  My thought is to pick a Discovery video that you will be showing in class and live blog it with your students.  The students could post comments onto the live blog as the video plays and create a back channel about the video.  The moderator (teacher) will choose which comments get added to the blog.  The teacher can also add in questions the students would ask during the video.  So instead of using the the paper and pencil “answer these questions while watching the video” a silent discussion about the video could be taking place.  In addition you could connect this with another classroom in the same building or across the world and be watching the same video at the same time.     I have not tried this yet but I plan on making this fit into my lessons for next year.  PS>>> Any one want to Back channel the DENny awards Thursday night…
