Scientific ways to improve academic performance:

1. Ensure 8 hours of sleep every day.

Don't stay up late at night and go to bed regularly. Insist on taking a nap at noon. Adequate sleep and full energy are the basic requirements for improving efficiency.

2. Be attentive when studying.

Play happily when you play, and learn seriously when you learn. It's not a good idea to sit at your desk all day long. When you learn to a certain extent, you have to rest and replenish your energy.

When you're not studying, be sure to take a break. But when studying, you must devote yourself wholeheartedly and use both hands and brains. When I study, I often have Tao Yuanming"Although it is in the downtown area, there is no hustle and bustle of cars and horses"In the realm, only my hands and brain communicate with the textbook.

3. Insist on physical exercise.

The body is"Learn"of the capital. Without a good body, no matter how great your ability is, you can't exert it. Therefore, no matter how busy you are studying, you can't ignore relaxation and exercise.

Some students neglect exercise for the sake of studying, their bodies are getting weaker and weaker, and they feel more and more unable to study. How can this improve learning efficiency?

Fourth, we should take the initiative in learning.

Only by taking the initiative to learn can we feel the joy of learning and become more and more interested in learning. With interest, efficiency increases imperceptibly. Some students have a bad foundation, and they always have problems that they don't understand in the learning process, and they are ashamed to ask others for advice, and the result is that they are depressed and absent-minded.

At this time, the only way is to ask people for advice, and do not understand the land.

Fang must understand and accumulate bit by bit in order to progress. In this way, efficiency can be gradually improved.

5. Maintain a happy mood and get along well with your classmates.

Have a good mood every day, do things neatly, learn actively and devotedly, and be naturally efficient. On the other hand, combining the individual and the collective, maintaining a mutual support relationship with classmates, and uniting and enterprising, can also improve learning efficiency.

Sixth, pay attention to tidying.

In the process of studying, the textbooks, assignments and materials of each subject are put together in a regular manner. When you're ready to use, you know where it's at a glance. And when some students look up a certain book, they look around and disappear.

Time passed in a hectic and anxious search. I don't think students who are organized will learn well.

To improve academic performance, there are mainly the following points, taking mathematics as an example.

1. Analyze the reason why the academic performance is not good, because the knowledge points are not firmly grasped, or the flexible operation is still not possible, or because of your own carelessness, resulting in some small details not being paid attention to.

2. Break each one. If there is a knowledge point that is not firmly grasped, it is necessary to thoroughly understand this knowledge point, pass the test of various tests and questions, and then operate flexibly, which is based on the mastery of knowledge points, and the former is the premise.

3. Summarize the reasons. After an exam, I lost my marks because of those factors, whether it was not a reasonable allocation of time, or too impatient or an imbalance in mentality, these should be analyzed.

The impromptu performance of the exam is very important, and there are only a few types of questions. The phrase "easy before difficult" is something that teachers say every time before an exam, but sometimes it's hard to do.

There's also the time factor, how much you plan to spend on it if you want to improve your academic performance. Because the improvement of academic performance is not achieved overnight, it takes a long period of perseverance, if you make up your mind, you have to give up a lot of personal time, and do not give up because the effect is not obvious for a while.

If your phone number is your score for this test, how much can you score

How to quickly improve academic performance, there is a trick, can you stick to it?

Cultivate your own interest in learning this course, this is the most important, if you really like it, you will take the initiative to explore and understand the wonderful world of the field, I believe your grades will be better improved.

You know, you know, you know, you know, you know, you know.

It's too general, you need to be specific, such as what to learn?

This question is more general, and it is relatively large, even academicians are not easy to answer, I will answer it with my only scientific knowledge, just for reference, first of all, science and technology are divided into many categories, materials science, biological science, physical science, mathematics, computer science... And so on, and these sciences are often not independent. interdependent.

The two biggest extremes of science are, in short, extremely abstract aspects (highly intelligent robots) and extremely concrete aspects (basic materials science).

For example: nano-level science, these fields fully experience the strength of things, computer chips, polymer materials are all manifestations of this aspect, the United States has the most right to speak, without these things there is no space engine, so far China does not have a real sense of independent research and development of space engines, but also need to import. For example, in large aircraft, not to mention the engine, even the control system of the aircraft China does not have a good product.

Supercomputer center, so far there is no computer center in China that uses its own chips, basically using Intel's CPU and NVIDIA's GPU. As for China's boast of being the world's No. 1, it's all nonsense, and many things need to be comprehensively evaluated.

Dude, if you want to have a good scientific literacy, it is recommended that you read more books in this area, of course, first of all, you must know some basic mathematics, physics, and chemistry knowledge, or you can't understand it, and moreover, watch more American science fiction blockbusters, Indian science fiction movies are also very good, no worse than Hollywood, and a lot of high-tech in the United States is inspired by movies.

In 1959, geologist Li Siguang and others put forward the theory of "terrestrial oil", breaking the theory of "China's poor oil" by Western scholars; In 1960, physicist Wang Ganchang and others discovered the anti-sigma negative hyperon; In 1964, China's first atomic bomb device was successful; In 1965, biologists synthesized bovine insulin for the first time in the world. In the process, China has formed a number of research institutes with complete disciplines and better equipment, and has cultivated a scientific research team with a relatively high level and strong strength. By 1965, there were more than 1,700 scientific research institutions and 120,000 people engaged in scientific research.

This is the foundation for the continued development of China's scientific and technological undertakings.

Zhan Tianyou and the Beijing-Zhangjiakou Railway: The Beijing-Zhangjiakou Railway is the first railway trunk line designed and constructed by the Chinese themselves, and was built when modern China was very backward in science and technology, and foreigners sarcastically mocked that Chinese railway engineers had not yet been born.

Feng Ru developed the aircraft: Feng Ru was China's first aircraft designer, manufacturer and aviator, and the flight altitude, speed and range of the aircraft developed by Feng Ru set world records at that time.

Weapons manufacturer Gong Zhenlin: After the outbreak of the Opium War, Gong Zhenlin saw that the great mountains and rivers were trampled by the British invaders, so he worked hard to study science and technology, improve weapons, and consciously devoted himself to the anti-aggression war. He personally went to the battlefield in Yongdong to carefully observe the British steamers, and made "wheel ships" and "wheel warships" driven by manpower.

During Lin Zexu's "meritorious service" in Zhejiang, he was transferred to work in the artillery bureau and built a "cardinal's new gun mount", which enabled the cannon to rotate in all directions and shoot flexibly.

Li Shanlan and Fang Yuan Illustrate the Secluded: Fang Yuan Illustrate the Secluded is a mathematical work of the Qing Dynasty. It is about the study of power series formulas.

Li Shanlan created a kind of "sharp pyramid technique" and used it for the power series of logarithmic functions; Solve a variety of math problems by finding the sum of the spikes. Although he had not yet been exposed to calculus when he created the "sharp cone", he had actually come up with formulas for definite integrals. The Englishman Wei Liali believes that in the book written by Li Shanlan, "the reason is very close to the differential".

Li Shanlan's achievement shows that even if there is no calculus introduced from the West, Chinese mathematics will use its own special way to achieve calculus in a unique way of thinking, and basically complete the transformation from elementary mathematics to advanced mathematics.
