The key concepts underpinning the "worthwhile lesson" model can be found in the slideshow below.
The key reading to start your learning about the "worthwhile lesson" is from the Moss and Brookhart book, "Formative Classroom Walkthroughs".

The "Collaborative Inquiry Guide for a Worthwhile Lesson" takes the main ideas from this chapter and provides a powerful guide for collaborative lesson development and professional conversations after lesson observations.
Check out the resources from our network's Instructional Rounds workshops that have included components of the worthwhile lesson model; and from the follow-up actions that schools have taken after their round.
