Tony's latest book, Change Leadership: A Practical Guide to Transforming Our Schools, has a number of exercises, which individuals or groups can use to further their learning and to assess their school or district's work.  It is available here at Amazon.com and elsewhere.  To preview one of the book's unique interactive exercises, where individuals or teams can "calibrate" their assessment of a videotaped lesson, click here to go the the Change Leadership Group's website.  From this site, you can stream a 12 minute video of either a 10th grade English class or a 6th grade Social Studies lesson, view it as a group, and discuss your assessment of the lesson, using the CLG exercise, which can also be downloaded from the CLG site.
