How to recite mathematical formulas efficiently
Memory can be divided into mechanical memory and meaningful memory. Mechanical memory is rote memorization of memory contents, which is very important for memorizing meaningless things, such as telephone numbers, mathematical formulas, English words and so on. Meaning memory is a kind of memory activity under the condition of fully understanding the meaning of memory content. However, mechanical memory and meaningful memory are not two completely different memories, but two different memory methods for different contents. Mechanical memory is easy to forget without repeated review, but the content of meaningful memory is relatively difficult to forget. So we encourage everyone to remember things in a meaningful way, and it is best not to use mechanical memory. But we can use the method of meaning memory to carry out mechanical memory, which is beneficial to improve learning efficiency. Here are some experiences:

1, image memory method

In the process of learning, some meaningless and boring materials are not easy to remember, and even if they are remembered, they are easy to forget. If these boring and meaningless materials are transformed into meaningful and vivid materials, it is not only easy to remember, but also difficult to forget.

For example, when primary school students learn pinyin letters "N, M, L", in order to make children remember them more firmly, teachers can vividly describe them as "one N, two M's, and a pig drives a stick L, L, L". I'm afraid this image memory will never be forgotten in my life.

2. Homophonic method

Turn learning materials into easy-to-remember materials that are homophonic with them.

For example, Marx was born in 18 18 and died in 1883, which can be homophonic as "climbing up and down". I remember when I was a freshman, I couldn't remember the word "enormours" and simply read it as "A Mu Si", which is still fresh in my memory. Many times, especially remembering English words, homophonic method is a better way to improve memory. Don't try.

3. Position conversion method

The place conversion method refers to memorizing different memory materials in different places, and then recalling the memory materials you have learned from these places. For example, students get up in the morning and write a few ancient poems in the dormitory, then write a few historical years when eating in the canteen, write an English word in the school garden and write a mathematical formula in the classroom. In this way, when you pass these places again, it is easy to remember what you remember.

4, the first word, keyword memory method

When memorizing some materials, especially many materials, it is difficult for us to memorize word by word. We can adopt the method of memorizing the first word and key words. There are many items in the answers to some questions in history, politics and other subjects. It is easy to be confused and forgotten when remembering. As long as you remember the first word and connect it consciously and vividly, it is not easy to be confused, and it is not easy to forget. Remember the key words, master the theme of the topic, and you can really master the knowledge.

The memory methods mentioned above are really helpful to improve learning efficiency. But memory involves not only the content of learning, but also the psychological problems of learning. Only good learning methods and good learning psychology can make memory more effective. Here are some suggestions to improve learning psychology:

1. Listen to a light music. Soft, soothing, quiet and elegant light music is conducive to calming emotions, regulating body and mind, slowing down breathing and heartbeat, and achieving a calm and relaxed state.

2. Take a deep breath and relax. If you have a hard day and your mind is in a mess, you can try to breathe and relax. You lie quietly in bed, close your eyes, inhale slowly and exhale slowly. When breathing, you should "count your breaths", that is, count the number of breaths silently, both when breathing and when inhaling. The purpose of "calculating interest" is to eliminate distractions, relieve tension and fatigue, and help you calm down as soon as possible to achieve a relaxed state.

3. Develop the good habit of sleeping regularly and getting up regularly. Good sleep habits are conducive to ensuring the quality of sleep, and high-quality sleep is the guarantee of effective sleep learning. Usually, we should fall asleep around 1 1 in the afternoon. After zero, the brain is in a state of high excitement. Even if I want to sleep, I can't restrain my excitement and it's hard to fall asleep. So listen to the recording before going to bed, relax from the brain, and gradually turn into a semi-sleep state until you fall asleep. Maybe you'll listen and fall asleep.
