This district has popped up on my radar before. They have a great website for their students and parents. The math section of the website has great resources (www.sowashco.k12.mn.us/virtualmedia).

Describes teacher observation for the 21st century. There is a good TED talk with Bill Gates that describes this. Seems scary, especially the full-time intrusion on the teacher, but the ideas are interesting. What if we gave teachers the opportunity to videotape themselves or have the classroom videotaped for a day and let them watch the tape? Just to let them reflect. Wouldn't that be valuable?
