A teacher is like a light in the darkness. The better the quality of a teacher, the brighter the light of the knowledge they can share. However, along the way, teachers still need the assistance of an educational supervisor. The supervisor's strategic role in assisting teachers is very important. Knowledge and skills regarding supervision as well as learning concepts determine the effectiveness of the supervisors themselves in improving the quality of teachers. Supervisors' mastery of strategies and techniques for coaching teachers as well as a comprehensive understanding of the problems, needs and characteristics of teachers lead to the achievement of effective supervision programs.
