This thumbs up, down, and sideways Student Self-Assessment Scale poster can help students assess their level of understanding during a lesson. Perfect for use with Marzano's Art and Science of Teaching Teacher Evaluation Model - Domain Question 1: Communicating Learning Goals and Feedback (Tracking Student Progress).
It is a quick way for the teacher to gauge levels of comprehension of a concept in a non-threatening way. When a student is asked to raise their hand if they don't understand, many times we don't get a true response because of the fear of being honest. Creating a system where all students quickly demonstrate their level of understanding with a 'thumb up', 'thumb down', or 'thumb sideways' ensures that all students participate. The students will learn to reflect on how well they understand what is being taught and the teacher will quickly know what concepts need reinforcement.
