Teachers are really good at figuring out if their students are learning what they’re supposed to, but how can they work together to make their teaching even better? In the Studio approach, teachers pick a question about their students and then adjust a colleague’s lesson plan to test out new teaching ideas. They watch the lesson in action and talk about what students did in relation to the learning goals. For example, they might look at how the questions they ask in class affect the answers they get from students, or they might explore which math tools help students understand fractions better. Studio is not about evaluating whether instructional practices are “good” or “bad”; it’s about researching student ways of thinking that result from decisions that teachers make.
