28 我的I28"Students should memorize facts only after they have studied the ideas, trends, and concepts that help explain those facts. Students who have learned only facts have learned very little."
The speaker made a extremely conclusion, he claimed that if student learn facts without its ideas, trends, and concepts, he will learned very little, admittedly, I
partly agree with the speaker, Concept, idea, and trends are very necessary part in students' studying process, if without them, the result of the studying might be abstract, however,
I am not agree with the speakers' ultimate claim, he claimed that students who have learned only facts will learned very little, this statement is an extreme conclusion, facts also plays an important role in the process of learning
In the research of natural science, take myself as an example, I am a postgraduate of forestry management field, in our study, the context of the theory, including history ,development, and conception are very essential, we always need to reading numerous reference, in order to make our research
In fact , In the history of science, there are many examples can prove this statement,
the theory of
acceleration of gravity is a good example, the conception of acceleration is very abstracted, when students cater this new theory, they may be confused, the explanation of this conception is the acceleration of a body in free fall under the influence of earth's gravity, expressed as the rate of increase of velocity per unit of time, this conception might be very confusion for most of junior school students, but when the teacher tells them a realistic experiment, the student will understand, the experiment is about two iron ball of different weight and same volume , when Galileo make the experiment in the leaning tower of Pisa, both two ball full down in the ground at the same time, during this explanation, all student will keep this theory in their mind,
similarly, polish astronomer who advanced the theory that the earth and other planets revolve around the sun, it is also a complicate conception, without the realistic example, students can not figure it out, teacher can told the students that this is the reason why day and night appearance alternatively in every day as well as fours seasons come in turn yearly. Beside these conception, when student learn principles of multiply, only remember the multiply tables is an useless way, they should learn the reason and how to use it. Therefore, during some of instance, we can realize the role of the ideas, trends, and concepts of a fact.
However, i strongly disagree with the speaker's claim of students will learn little if only remember the facts. when we were young, the comprehensive ability of our brand has not matured, most thing we had learn were depended on abstract memory, our parents told us the norm of morality, such as revering elders and caring the young, industrious and frugal, politeness, in that time we have not understand why we should do it, but these facts stand in our mind and can not be forgot
To sum up, only by gaining useful perspectives and insights about facts can students learn, make comprehension and memory together is the best way to study. These two abilities are two different kinds way of study; generally, memory plays vital part in our childhood, when we become mature, comprehensive memory took the place. in one hand, emphasis the comprehension overly will lead students overlook conception and the importance of factor, and probably made them can not use what they have learned in the future skillfully. on the other hand, emphasis the memory too much, will make students lost the interesting of study and ability of solve problem, so, mix these two part, student will get better improved |
