There are many things I love about Doug Lemov’s post Exit Tickets that Encourage Self-reflection. The substance of it is important – I recently added something similar to my APWH Exit Tickets (I think I stole it from some awesome teacher at KIPP). But what I really like about the post is that it captures what Doug and the crew at Teach Like a Champion do so well – they watch what teachers do, write about it in a way that others can replicate, and then add to it as they hear from more great teachers. While the formula appears obvious, it takes a lot of time and patience to do it right, and that’s why their work can be so valuable.
