What do teachers actually want from post-observation feedback? Evidence you watched the classroom. What makes it land: specificity as proof of attention, questions over verdicts, one focused next step, and timing that keeps the lesson fresh.
What to look for in the first five minutes of a classroom walkthrough: not the teacher, the learning. What the students are doing, what the room reveals, what the teacher's decisions show, and what the lesson says about the weeks before it.
