The primary aim of education is the total development of the child. In the past the child occupied the pivotal position in the educational area. But now the child occupies the central position. Modern education is child-centric, that is why psychology studies the nature and behaviour of the child in different facets. Child centricism is the direct effect of psychology on education.
In modern education, the concept of school has undergone tremendous changes. The school is now regarded as the replica of the society. For bringing desirable and permanent changes in the child the school should be organized as a society. So the child should be educated in the social environment of the school. Thus in modern education the concept of school has greatly been influenced by the theory and practice of social psychology.
Another important theoretical aspect of modern education is the activity principle. This means that the child should learn through self- activity. According to the psychologists activity is the natural tendency of the child. His natural inclinations are expressed through his activity. Education can be meaningful if these inclinations are utilized for the purpose of education. This activity principle is based on the psychological theory.
In modern times the meaning of education has changed to a great extent. It is a life-long process from birth to maturity. Education is the process of acquiring experience throughout life. Growth brings changes in the behaviour pattern of the child. Changes take place through the adjustment to the environment in which the child lives. In the way of adjustment the child acquires new experiences and this process of acquiring experience is education. Thus this new meaning of education has psychological basis.
