1.     Manager/controller – Teachers are expected to act as managers for “teacher-centered” lessons like explaining or lecturing about a new topic or concept to the students. This role is important at the beginning of a new lesson/class but it should not always be the case. Teachers should be careful when taking on this role and avoid too much “teacher talk time”.  2.     Organizer – Teachers become organizers when they try to give instructions for an activity and put students into pairs/groups. This is very important in the ESL classroom because classes can become noisy if the students are not aware of the tasks or don’t know how to go about with their tasks.  3.     Prompter – A teacher becomes a prompter when the students suddenly run out of things to say or forget the words while answering. In this case, the teacher can try to help by offering different choices of words. This role is essential because it can avoid situations wherein the rest of the class is becoming impatient and bored while waiting for a student to think of the correct word to say. However, teachers should be careful not to take the initiative away from the learners and end up spoon-feeding the students. 4.     Assessor – When a teacher starts measuring the progress of the students, he/she is acting as an assessor. This is very important because learners want to know how they are performing in the class. Adults want to be aware of their mistakes and parents of young learners want to know how their children are doing in class. In this case, teachers should make sure they are fair and consistent in their assessment and should not give false hopes to the students just to please them. 5.     Observer – With some activities in class, a teacher doesn’t need to involve himself/herself actively. Rather, he/can just move around the class, observe the students, and take notes. Again, this role is important because it gives the students more “talk time” rather than “teacher talk time”. It allows for more speaking practice in the class. It gives the teacher the opportunity to check on the mistakes that are consistently being done by the students and monitor student participation.
