  Introduction: The main aimof teaching is to bring about socially desirable behavior change in the students and this can only be achieved if the teaching is effective and based on the principles of teaching. How the pupils will learn effectively, depends on the methods the teacher adopts. There is the great world outside and the mind within and it is the duty of the teacher to bring the two together. This process of interpreting the world of knowledge to the child’s mind is called the ‘Method of teaching’. It is just a way of teaching. Method is the style of presentation of the content to the classroom.
