The Concept of Supervision
In the words of Moorar in Kochhar (2005), supervision include those activities which are primarily and directly concerned with studying and improving the conditions of which surround thelearning and growth of pupils. Supervision is that which helps to improve the teaching function (Igbo,2002). According to Nwaogu (1980), supervision is the process of helping, guiding, advising and stimulating growth in asubordinate in order to improve on the quality of his work. Supervision is therefore any programmewhich helps teachers achieve both qualitative and quantitative instructional delivery. From the foregoing,it could easily be deduced that supervision is an indispensable variable in the teaching learning process, aswell as the overall school and educational objectives. Supervision involves supervising the teaching cumclassroom activities of the teacher.It is important to state that supervision of instruction can only be said to be effective if it achievesits stated objectives, which is quality instructional delivery.
Anything to the contrary means the failure ofthe programme of supervision. It then becomes imperative to distinguish between supervision an dinspection. Both processes aim at checking the work of subordinates. Inspection as a concept is however more outdated. It aims at evaluating the work of the teacher. It is more prone to fault finding. On the other hand, supervision which is a more modern concept aims at helping the teacher improve on his work.It aims at helping the teacher become a better teacher, especially in his capacity to deliver quality instruction to the students
