In a well-disciplined classroom, the room itself is appealing. Many of us teach in cramped and overcrowded rooms without enough basic materials and certainly not expensive equipment such as interactive whiteboards and LCD projectors. Despite these restrictions, effective secondary teachers can manage to create an environment where students focus on learning. We can arrange desks to encourage collaboration as well as independent work, minimize traffic-flow problems, and make sure materials are readily available. The walls can be used to stimulate student engagement with displays of student work.
