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. Modern treatises on education depict this changing trends. For a long time, the shaping and development of character of the child was considered one of the chief objectives of education. Now-a-days its aim has been re-stated in economic terms as the investment in human resource development which, of course, includes the development of character and inculcation of permanent values in individuals. This tendency in education is indicative of the continuous growth of education as a science. Very often in the present context, the word 'modern' implies the Western system of education of modern times. The whole exercise of education revolves round the processes of learning and teaching which have undergone a continuous evolution.
