The teacher plays many important roles in educating students. They act as a model, motivator, and second parent. In the classroom, a teacher can take on roles like an observer, controller, prompter, tutor, organizer, assessor, participant, or resource. Each role serves a different purpose, such as observing student work, controlling class activities, motivating students, tutoring small groups, organizing lessons, assessing student performance, participating with students, or providing classroom resources.
