High school mathematics: if you can understand in class, you will be confused when you do problems. Why?

How's it going? See if there's a title. How do you know! ? What about the feeling? For students with poor foundation, the most painful thing is to finally understand the lecture. Once they do the problem, they find that they can't do it. Not when it comes to the questions on the test paper. Let's talk about it ~ what's going on? ! !

A said: it is not difficult to understand the text, but the difficult thing is to do the problem. I died as soon as I did the problem ~ I lost confidence.

B said: I am in a painful problem now, depression. It's hard, hard, really hard!

C said: It's not the first time, you can do it while reading the answer, and then read the answer after the second time. After the third time, the result will be very different. You must do it at least three times!

D said: knowing a little is almost the same as not knowing. Now I can only understand. My goal is to be able to deal with it. These are two grades, far from each other. There is no other way, just keep listening and writing.

Many students ask:? I can understand the lecture, but I can't do the problem. What happened?

In fact, most of the problems of such students are here:

(1) You only know shallow knowledge, but you don't go deep into it, and what you master can't reach the height of application;

(2) Some students try a little and think they can do it. For example, an example teacher talked about three methods, and after understanding one, he would not listen to other solutions.

(3) Understand the knowledge, but can't remember it, or don't understand how to apply it;

(4) Lack of guidance of mathematical thinking methods, such as equation thinking and classified discussion thinking are all important mathematical thinking methods;

In addition, some students simply don't listen to math because of lack of confidence, so they can't go deep into it. We all want to learn math well, but? If you want to learn well, why didn't you learn well?

A necessary condition for learning mathematics well: learning? Miyoshi students? Three good things add up to one good (good grades) and are indispensable.

Good habits are a necessary condition for achieving excellent results, which can get twice the result with half the effort. What is a good habit?

1.

Hands-on: Take more notes (class notes, good questions, easy solutions and wrong questions), do more exercises, and summarize more (knowledge summary and method summary).

Eye-catching: read more textbooks, extracurricular books, notes, and wrong books.

Erqin: Listen carefully.

Mouth-to-mouth: ask more questions, solve problems in time, and leave no future trouble.

Brain Qin: Think more, not only to find out what knowledge and topics are, how to do them, but also to think more about why. The most important thing is to use your hands and brain.

go deep into

We should not only remember what we have learned, but also find out how it came from. How to use it in solving problems? Don't be satisfied with knowing how to do some good problems, but also consider how to come up with solutions. Which method is better?

? what's up There are different levels: knowledge: know? Do you understand? Remember? Can you use it? Popularize problem solving: can you do the problem? Can you do a problem? Flexible use and innovation

strict

Mathematics is the most rigorous subject. Knowledge should be rigorous and problem-solving should be rigorous. If you are not rigorous, you will not do the problem, or the solution is incomplete and the score is incomplete.

4. Others

A) Get rid of bad habits: Internet, TV, mobile phone, etc. And turn them into learning tools.

B) Don't make excuses: when your grades are not good, make more excuses for yourself and don't blame others. The same teachers, the same classmates, the same textbooks and reference books, the same test papers, but the results are very different, so the main reason is personal. Using excuses to cover up the real reasons is not conducive to solving practical problems.

Advice: Learning is your own business, and no one can do it for you! Parents and teachers are cooks. They can only make food more delicious, nutritious and digestible, but it will only be effective if you love it. Therefore, as students, we should realize our position in learning.

Basic knowledge should be solid, and if you want to get points, you must have capital.

Give an inappropriate example, just like doing business. If you invest 1 yuan, even if you make a profit 100%, that is, if you invest 1 00000 yuan, even if you only make a profit 100%, it is still a profit 100 yuan. Therefore, if you want to improve your academic performance greatly, you must have a solid knowledge reserve.

So, if you have a base of 20 points, you can get 40 points by increasing 100%. Here are some suggestions on how to lay a good foundation:

A) Self-compensation: Simple knowledge can self-compensate. As you get older, your intelligence improves. What used to be difficult to learn may now be clear at a glance.

B) Individual guidance: For difficult knowledge, you can consult your teacher for targeted guidance. However, we should understand that individual guidance is only an emergency measure and cannot be relied on.

C) Information: With the help of some information, you can quickly supplement the basic knowledge. Basic knowledge is not everything. You can't do anything without basic knowledge. This is about the relationship between knowledge and problem solving. Understanding the knowledge points may not solve the problem, but 100% will not solve the problem if the knowledge points used are not mastered.

Work hard and get out of the vicious circle

A virtuous circle: do the questions quickly? Less time? Solve more problems? More capable? It's faster to do the problem.

Vicious circle: slow to do the problem? How long will it take? Less problem solving? Worse ability? Doing problems is slow. Once in a vicious circle, students are very distressed.

What is the general solution to the vicious circle? Catch up? That is, people let you rest endlessly, and people play with you less or not.

After a period of hard work, a virtuous circle will gradually form, and future problems will become easier. Especially the kind that used to go bad suddenly, which is very useful.

Preview is very important.

Often overlooked, the reason: no time, no understanding, no need to wait. Preview is a necessary process of learning and a good way to improve self-study ability.

2. Listening and learning

Listen to the analysis, ideas, applications, every word of the key content, and pay attention to the record.

3. Do a good job in the wrong book

Every student who can learn will have it. Better add another one? Okay, question Ben? . I found that many students either didn't have the wrong problem books or made mistakes. This research has no effect.

4. Make good use of extracurricular books

A correct understanding of online courses and extracurricular books is a non-staple food and medicine to help absorption, and can never replace classroom learning.

5. Pay attention to summarize and reflect on knowledge points, problem-solving methods and skills, experiences and lessons.

6. Accept the guidance of mathematical thinking methods:

Pay attention to the guidance of mathematical thinking methods, stand high and look far.
