Teachers play multiple roles in the classroom. At the planning stage, teachers learn best strategies, collaborate with other teachers, analyze student data, and design engaging lesson plans. During instruction, teachers facilitate learning by providing students with information and tools to master subjects, and work individually with students. Learner-centered teaching engages and motivates students, includes explicit skill instruction, and encourages collaboration. Moving to a more facilitative role is difficult for teachers as they like being the center of attention, students may resist, and the new role requires patience and is time-consuming. Principles for the facilitative role include doing less telling and more designing authentic learning tasks, modeling thinking, encouraging peer learning, and providing constructive feedback.
