In the teaching process of Wanzhi school, the teachers of mathematics department found that some students listened very carefully in class. As a result, after one class, they felt that they had learned nothing. Some students do not seem to listen very seriously, but they will not miss the key things, and then their grades will be very good. How can they do that? In fact, it's very simple, that is, taking notes. But taking notes is also skillful. How to take notes? What do you remember?

1.用笔记记一些老师补充的例题

1. Take notes of some examples added by the teacher

老师讲的这些例题，往往都是比较精华的知识点，都是历久弥新的。在记笔记的时候，把题目抄下来，然后记一个解体思路，这个比较重要，有些思路揣摸一下，就可以解很多同一类型的其他题，方便你举一反三，以后碰到这样的题就会有点思路。具体的解法没必要记，记个答案就可以了，这样可以节省很多宝贵的课堂时间。

These examples, which are often mentioned by the teacher, are always the essence of knowledge. When taking notes, copy down the topic, and then write down a disintegration idea. This is more important. Some ideas can solve many other problems of the same type by guessing. It's convenient for you to draw inferences from one instance. When you encounter such problems in the future, you will have some ideas. There is no need to remember the specific solution, just remember the answer, which can save a lot of valuable classroom time.

2.抓住关键点进行记笔记

2. Grasp the key points and take notes

有时候老师在介绍一种解题方法的时候，会很形象地取上一些有趣的名字，比如穿针引线法。可以把这些形象的名字记在题目的边上，记起来特别快。下次一看到这个名字，解题方法就在你的脑海中闪现，想忘记都难，这样子学习也不会觉得很枯燥。在记到老师讲的一些重点的时候，可以在一旁用重点号标一下，这样看起来也会比较清楚、醒目。

Sometimes when the teacher introduces a method of solving a problem, he will vividly take some interesting names, such as the method of threading a needle. You can put the names of these images on the edge of the title, which is very fast. The next time you see the name, the problem-solving method will flash in your mind. It's hard to forget, so that you won't feel boring. When you remember some of the key points that the teacher said, you can mark them with the key number on the side, so that they will look clear and eye-catching.
             

3.记笔记就是为了整理笔记

3. Taking notes is to organize the notes

老师上课讲的题通常都会有很多其他解法，由于时间关系，老师通常只会讲一下大致的解题方法、思路。在整理笔记的时候，可以把各种各样的解法都写上去，哪种简单哪种复杂一目了然。反正多会几种方法也不是坏事，你的思路会变得更加开阔。笔记是比较开放的东西，反正就只有自己看，想怎么弄就可以怎么弄，精心地去做这件事，总是会有收获的。

Teachers usually have many other solutions to the problems in class. Because of the time, teachers usually only talk about the general solution methods and ideas. When sorting out the notes, you can write down all kinds of solutions, which are simple and which are complex at a glance. Anyway, it's not a bad thing to have more ways. Your mind will become more open. Note taking is a relatively open thing. Anyway, you can only see for yourself. You can do it as you like. If you do it carefully, you will always get something.

当然，有时候上课老师讲的地方，有一点点不明白的，就要大胆地课下去问，问同学总没有老师解释的那么清晰。有时候一个问题没有解决，一连串的东西都会搞不清楚，所以当天的东西当天就必须全部消化掉，不要遗留下来。有问题要多问，这样也是和老师的一种沟通。

Of course, sometimes when there is something the teacher doesn't understand in class, we should boldly ask after class. Asking students is not as clear as the teacher's explanation. Sometimes, if a problem is not solved, a series of things will be confused, so all the things of the day must be digested on the day, not left behind. If you have any questions, you should ask more. This is also a kind of communication with teachers.
