The document discusses 22 formative assessment techniques that teachers can use to evaluate student learning in the classroom. The techniques are simple to administer and provide teachers with evidence of student understanding to help adjust lesson plans. They also help students understand where they need to focus their efforts. Some of the techniques discussed include using popsicle sticks to call on random students, exit tickets where students submit answers before leaving class, using whiteboards for students to show answers, and think-pair-share activities.
