Definition of Supervision Modern supervisory concepts formulated by Kimball Wiles (1967) as follows: "Supervision is assistance in the devolepment of a better teaching learning situation."Supervision is to help in developing a better learning situation. This formula implies that the service covers the overall supervision of teaching and learning situation (goal, material, technique, method, teacher, student, an envirovment). This learning situation should be improved and enhanced through service activities supervision. Thus, these supervision services covering all aspects of the conduct of education and teaching. The concept of supervision can not be equated with the inspections, inspections and more emphasis on authoritarian rule, while supervising more emphasis to the friendship which is based on service delivery and better cooperation among the teachers, because it is democratic. The term supervision of education can be explained either by the origin (etymology), the form of words (morphology), or the content contained in these words (semantics).
