When students are engaged with the class, and trust their teacher, they are eager and willing to answer questions. Unfortunately, sometimes students raise their hands or blurt out an answer without really thinking about what they know. Eagerness wins over thoughtful reflection. To help students reflect on what they know, I have developed a suite of strategies that work in classes, both for regular and special education. This poster is about confidence. When you ask students a question, have them consider their confidence before they raise their hands. How sure are they that the answer is correct? If they are 100% confident, they should put up two thumbs. If they are fairly confident, put up one thumb. And if they are unsure or don't know, but one thumb up and one down. Wait for everyone to vote before you call on a student. The magic here is that everyone slows down and considers their answer, and some two thumbers will actually revise their decision if they see a lot of one thumbers. It's fun, effective, and you get an easy formative assessment!
