The present day world is facing two general problems-“information explosions” and the “population explosion”. Information explosion means an explosion of knowledge. Today, throughout the world, social and technological changes are taking place rapidly due to expanding world of information. So there is explosion of knowledge. New frontiers of knowledge are opening day by day and the horizon of human knowledge and understanding is expanding very fast.
On the other hand, with the explosion of knowledge there is also population explosion. The student population is immensely increasing year by year due to the growth of population and democratisation of education with varying levels of motivation and aspiration. The problem of” population explosion” is more serious in the developing countries than the developed one. India is facing serious difficulties both from population as well as information explosion.
So the two general factors – “information explosion” and ” Population explosion” have posed critical problems for education-more things to be learnt and more people to be taught. Today there is a cry for “more education to more people in less time”. For solving these problems successfully, educational technology consisting of various media of mass communication are essentially required. Both qualitative improvement and quantitative expansion of education can be facilitated and accelerated with the help of this mass media under educational technology. So the mass-media has come to our rescue to tackle this problem.
Education of tomorrow will be able to play its role more effectively by making the individuals creative, active and efficient. Success of education cannot be achieved merely by substituting mechanical methods for human beings, but by developing new patterns using both human beings and technological advancements in order to teach more people better and more rapidly.
There are a good number of media for mass communication such as radio, Television, newspapers and films etc. Previously, the mass media in the form of illustrative were only put to marginal and individualised use. There was neither any coherent thinking nor a scientific organisation of these materials in the educational process. But their increased use has been mainly due to interest and initiative of certain teachers.
The media of communication is the medium by which a piece of information or knowledge is communicated to us. This medium is the message, which is of greater importance. Because, the same piece of information when conveyed on a printed page or over the telephone by radio, or television will appear different and have entirely a different effect on us. Hence the effectiveness of a piece of information depends upon the medium through which it is imparted. Thus, the mass-media are not only the messages, but also the massage.
Because, it massages the sensory organs and stimulates them to respond actively. Hence, the mass media is very important for class room teaching as a part of the process of instruction. The sole objective is to improve the teaching- learning process with the use of various media. Therefore, the main purpose of mass-media in education is to benefit more students with fewer teachers or to obtain quality education.
In fact, the mass media have become a well of message around the world of today and have entered into all the structures of daily life, h can be used and in fact is being used as a means of education. So the role of mass media in education is gaining importance every day.
