It could be assumed that effective teachers would be successful in any classroom, whether large or small. They give clear and focused instruction in a highly efficient classroom setting.
Good teachers monitor their students' learning and reteach students when necessary.
They set high behavioral standards and also maintain personal interactions with their students. They are characterized as motivated and enthusiastic. These characteristics are necessary in any classroom setting. To get the most out of smaller classes, however, policymakers must ensure that these practices actually occur in small-class settings. More time for teaching and learning, and more space in which to do so.
