As a coach, one of the best parts of your job is telling teachers what they're doing well. Making the time to validate their classroom decisions--in precise and student-facing language--has two tangible benefits. First, you'll make them aware of effective strategies that they may not even have been implementing consciously. After all, they're focusing on the lesson! And even more importantly, you can reinforce a growth mindset by validating when they master a move they've been working on. Oh, and hat tip to Doug Lemov, who uses the term "precise praise" to describe how to deliver in-the-moment positive feedback to students!
