The memorization of information by frequent repeat is not so practical to all subjects, like medicine, history, etc. Take history for the first example. No doubt, anyone could and can memorize all of historical events occurring in the past by frequent repeat, but it is and will be impossible to automatically or fully draw on the lessons as well as experiences from these events without deeply thinking by any governor, historian, teacher and student. Another example is that the main goal of an apprentice or internee on medicine is to be a future expert. How can he achieve it? Needless to say, he will warrant his success through a huge practice rather than mechanically learning.
It is a fact that learning by rote is a basic approach to education. By reciting or memorizing, to some extent, a student can improve his academic performance on objective tests, consisting of multiple choice, matching, filling in blank and etc; however, one distinguished Nobel Prize Winner, YuanZhe Li, a headmaster of scientific technology research center of Taiwan of China, graduated from the University of California at Berkeley, ever said that objective tests test memorization, but good writers can get good grades despite they do not mechanically recite the information. He also said that in the future, students will need the skills for subjective tests, not objective tests. So, the best way of a test in education systems does not always depend on memorization of information.
