Whether the subject should be taught in English in our educational institutions or through the medium of our mother tongue is one of the most important problems of the present day. These are quite a few points to be considered in this connection. Those who oppose the introduction of English as a medium of instruction think that the subject taught in English are not properly understood by the students.when they are not able to understand a point properly, they are evidently unable to express it properly.When they are compelled to write the answer in English they feel pained. Hence they develop a sort of inferiority complex. This thing mars the growth of intellectual power and as a result their personality remains undeveloped. Thus, they prove a complete failure in their lives. But that is not a sensible way of thinking. As a matter of fact, it is not simply the medium of instruction that counts in the educational affairs. There are some other factors as well to be taken into consideration of mind, etc. Moreover, in Pakistan Urdu is still in a stage of infancy. It is impossible for it to compete with English at this stage. So we should wait till such a time when it becomes mature enough to absorb suitable equivalents of technical terms before it is introduced as a medium of instruction. The change, of course, must be there, but it must be very gradual one.
