We may be very pleased with the rapid progress we have made in every field of study. But the way to test a student's knowledge and ability still remains-as poor as it was. We have almost done nothing to improve our examination system.
It is well known that the exanunation system we are now using may be a good way of testing a student's memory, but it can tell you nothing about a student's ability. It does no good to students and teachers.
As soon as a child begins school, he enters a world of examination that will decide his future job. In fact a good examination system should train a student to think for himself. But it now does nothing about that. Students are encouraged to remember what is taught. It does not enable them to gain more new knowledge. The students who come out first in the examination often may not be the best in their studies.
Besides, the examinations often force teachers to train students what to do with the coming examination from time to time. There must be some simpler and better way to test a student' s ability besides knowledge. And that is what we should do at once.
56. The most suitable title of this passage is _________
[ A] Progress in the Field of Study
[ B ] Teachers' Role in Study
[ C ] How to Improve Students' Ability
[ D ] Bad Points of the Examination System
