28"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."

提纲：1指出现学习原理的好处，可以从整体上把握    并且可以随着对事实的了解更加深入的掌握原理
  例子:
   2指出对于有些领域，刚开始就将原理显然是很难理解
   3 指出对于任何理论的学习两者都需要

Should students memorize facts before they learn the ideas, trends and concepts or do in a contrast way? People may have different opinions. As far as I am concerned, I fundamentally agree with the statement of the speaker, however, we should not ignore that in some situations, learning the facts before contacting with the ideas are more helpful for students to truly master the knowledge.

First of all, learning the ideas, trends and concepts before memorizing the facts can promote the students gain a general view to the subject they are studying and the students can also deepen the understanding of the ideas or concepts with the memorizing more facts in later period. As we all know, the ideas, concepts generally stem from variable facts and they are the generalized things can explain all the facts related with the concepts. In this sense, when students learn the ideas or concepts, they will get to know the total picture what the some knowledge refer to which will help them understand the whole field. For example, when students are tying to learn the knowledge of line in maths, if they are only taught to draw a certain series of lines, they can only draw the line what they learn in the class. But if they are asked to draw some different line they are not taught, they will have no idea at all. however, if they
Know the general formulation of line : y=kx+c, then they will be able to draw variable lines by determining the factors k ,c and a point.

Although mastering the principles, ideas is very important for a student to get the knowledge, the reverse way is also useful in some cases. It has proved that the order of we human being thinking a things is from concrete to abstraction. Here. We can say facts stand for the concrete things, and ideas stands for the abstraction. Therefore, when students are trying to touch a certain field which may be strange and hard- comprehensible for them, memorizing the facts first is necessary. For example, the concept ”operating database” in computer science is relatively hard to understand for students who have never known anything about the database. In this case, if at the beginning we tell the students about the internal mechanism how the database works, how frustrated they will feel! They will get the sense of hard, boring which lead to the dislike of the subject. So as to avoid this situation, teaching the facts of how they can operate the database visually will greatly enhance the interest of student to the subject, because they can get the immediate result from the operations. Later after they can manipulate the database, they will more easily to understand the mysterious internal mechanism of database, thus they can understand the essence of the database.

Of course, in order to learn a theory of something else new, it is dispensable to learn both the facts and the ideas. We can regard the facts as how to apply a theory to the practical life and regard ideas as why the theory can be implemented in such a way. That means if we do not know the ideas, we will not know the fundamental part of the theory. And if we do not know the facts, the theory will be useless for us because we are incapable of applying them to serve for the whole society. Therefore, we cannot ignore either the ideas or the facts.

In sum, when learning something new, we ,must learn both the ideas and facts. And the order of which one should be learned first depends on the knowledge they students are going to learn.
