Education enables man to live in the contemporary society successfully by giving him systematic intellectual and moral instruction and training. His knowledge, abilities, character, mental faculties etc. are developed through a well-planned process of education. Unprecedented changes have taken place in all areas of modern education, especially in terms of restatement of its aims, restructuring of its curricula, re-scheduling of teaching-learning processes, re-consideration of the socio-economic status of the teacher, re-definition of the value system etc.
