This topic brief is one in a series on personalized learning prepared for Conversations with Innovators, 2018. Norming is an important factor in developing positive classroom and school culture. Norms are specific expectations that teachers and students establish to manage behavior toward one another and the school environment. They are part of what makes students feel safe, brings students together as a cohesive group, and helps students build connections to one another. When students participate in creating norms, they are more likely to participate in instruction and engage in cooperative relationships with one another. They also better understand the classroom expectations and begin to monitor and change their own behaviors. Norming is one of the four essential personal competencies emphasized by the Center on Innovations in Learning. This brief discusses how norming relates to personalized learning, why norming should be included in planning, and how to create norms in classroom or school.
