Keep the knowledge "Fresh"
( 2003-07-10 10:39) (PLA Daily)
According to a survey, nowadays, scientific
knowledge will be doubled in every three to five years. When a student graduates
from the college, a large part of his/her knowledge has already been out of
date. Many people have been thinking about the question of how to keep the
knowledge fresh, and how to expand the life of knowledge for a long time.
A graduate-to-be once said that the equipment in the army was more advanced
than those taught in the universities. After three years study, one almost could
not keep up with the changing times. These words could make people feel deeply
worried. Those who had the experiences of buying fresh vegetables in the market
would know "fresh" was the most important thing. This was also true in
knowledge. In the ever-changing military fields, to improve the knowledge and
expand its life, "fresh" was the most important factor. The universities must
teach the newest knowledge to the students , otherwise, the knowledge could not
use for a long time.
People often said that to give a student a glass of water, the teacher must
have a barrel of it. The meaning in it was not as simple as it read. It was not
just the problem of a glass of water or a barrel of water. It was the essence of
the water. In the era of knowledge explosion, the time and energy of a person
was so limited that one could not go to study everything. So one had to select
to learn. As a teacher, he/she had to increase the validity of the "knowledge
filtration" to ensure the "freshness" of it. Obviously, the most effective way
of expending the life of knowledge was to increase the value of it.
Some rich people prefer goods with famous brand. They think that famous brand
meant high quality. It can not be left behind years later or dozens of years
later. To put this theory into knowledge learning, people can get the same
result. To learn "famous brand" means to learn high quality knowledge. There is
a metaphor goes like this: Illiterates in the past were those who could not read
and write, but nowadays they are those who don't know how to study. Therefore,
the teachers should pay more attention to methods of learning and process of
thinking to get the scientific conclusion. Thus, when the students knew how to
study and how to renew his knowledge, then, to keep knowledge "fresh" would not
be just a dream in the future.
