Education has always been instrumental in the process of individual and national development. The role and functions of a teacher are continuously changing in the present world. Perhaps, that is why, the expectations of the society from a teacher are more and more. In spite of the developments in technology, the teacher has been indispensable. Indian Education commission has rightly said:
"Of all the different factors which affect the quality of education and its contribution to national development; the quality, competence and character of a teacher are undoubtedly the most significant."
