This is the most effective way to learn

Chapter 32 Interleaving Learning Improves Memory

By rationally allocating time, allocating memorization materials of different natures according to time, and memorizing them alternately in turn, this is the cross-memory method.

The brain is prone to fatigue after memorizing the same knowledge for a long time.Chernyshevsky said: "A change of work is equal to a rest."

Experiments have shown that simply memorizing knowledge of a subject for a long time is not effective, because materials with the same nature stimulate the brain nerves too monotonously. Over time, the corresponding areas of the brain are easily overburdened and fatigued.At this time, there will be dizziness, inattention and other phenomena.In order to avoid this phenomenon, generally study for about an hour, it is best to relax for a few minutes: stand up and walk around, go outside, and then change to another type of learning material.This helps to "switch the exciting center of the brain", eliminate inhibition, and improve the work efficiency of the brain.

Many successful people use this method.When Marx was writing "Das Kapital", he interspersed with advanced mathematics calculations, and sometimes went for a walk outside.Physicist and chemist Marie Curie said when talking about her learning method: "I read several books at the same time, because studying one thing will make my precious mind tired. It is already too hard!"

It seems that everyone knows the truth, but in reality, many students do not leave the room after class because they do not understand the benefits of alternate memory method. After one class, the energy is not so abundant.Or study hard before the exam, swear at a subject, make you exhausted, and don't want to stand up and move around from time to time. As a result, the time is used, but the effect is not ideal.

Memorizing a kind of knowledge content for a long time will interfere with each other
Memorizing a kind of knowledge for a long time, in addition to the fatigue of the brain will lead to a decrease in efficiency, psychological research also tells us that the content of memorizing before and after will also interfere with each other, thus affecting the memory effect.That is, there is the phenomenon of proactive inhibition and retroactive inhibition mentioned above.

In order to reduce this inhibition, you can interleave the memorization of different memorization materials, shorten the time for continuous memorization of the same material, and make the materials memorized before and after have less similarity.Studies have shown that the greater the similarity of content, the greater the mutual interference.Even if the materials are different, there is mutual interference.Psychologists once did an experiment: Stimulate the brain with electrical pulses of the same frequency. At the beginning of the stimulation, the nerve cells responded very quickly, but after repeated stimulation for a long time, the response became weaker and weaker.After resting for a period of time, or changing the frequency of electrical pulses and then stimulating, the response will return to normal.This tells us that studying or reviewing a subject for a long time is not effective.Different subjects, such as liberal arts and science, should be alternated, so that the effect of memory will be better.

cross memory cross to science

Lenin said in a letter to his sister:

I advise you to allocate time correctly according to the existing books and diversify the learning content.I clearly remember that changing the content of reading or work, reading after translation, gymnastics after writing, reading novels after reading important books, is very beneficial... But the most important thing is not to forget that you must do it every day. Gymnastics, it is very important to make yourself do dozens of (literally) different movements every day.

What Lenin talked about here is the method of cross-memory.This alternation, on the one hand, is the alternation of different learning contents and different subjects; on the other hand, it is the alternation of study and rest, study and physical exercise.Use your brain scientifically to achieve the best learning results.

Therefore, in our study, we should pay attention to:
(1) The study load should be appropriate, and the materials should be interspersed.

We learn a lot now, but the percentage of forgetting is relatively high, which makes it difficult to remember.Therefore, don't be too greedy to chew more than you can chew, and haste makes waste.In addition, since brain cells have a division of labor, students should learn materials alternately according to this law, so as to shift the brain's excitement center, reduce mutual interference between subjects with similar content, eliminate inhibition, and improve brain work efficiency.

(2) There must be intervals in time.

People of different ages have different attention spans.Generally speaking, the time for middle school students to concentrate on a homework is [-] minutes to [-] minutes, and college students can keep it for [-] minutes to [-] minutes.After working, it will be longer, about [-] hours.Grasping the laws of individual differences can easily improve the efficiency of memory.When you can't concentrate, you can arrange a break and go outdoors to do some exercise.It can relieve brain fatigue and consolidate the acquired knowledge.Exercise between classes is to interrupt a memory sequence in the morning and turn it into two memory sequences.Taking a nap can minimize the inhibition between the morning and afternoon, so as to restore the energy for studying in the afternoon and evening.

(3) Pay close attention to physical exercise.

Due to long-term thinking and memory, the blood in the brain will decrease, and the memory effect will decrease accordingly.Carry out physical activities in good time to promote blood circulation throughout the body, eliminate fatigue, refresh your mind, and then carry out reading and memory, thereby improving the memory effect.

(4) Material selection.

When switching between different memory materials, try to avoid too much difference in the properties of the materials, otherwise, it will easily cause difficulties in knowledge connection and inactive thinking.

(5) Avoid distractions.

When studying and resting, try not to do things that distract or overtire your study, such as playing video games, playing football, etc., so that your mind cannot quickly enter the state of learning and waste a lot of energy.

learning english with cross memory

Some friends always say that English words are hard to remember. In fact, they have not found a good way to memorize them. Using the cross-memory method will get unexpected results.You can recite five words every morning when you wake up, and you can deepen your memory when you eat. You can recite five words in the morning after school or before getting off work. You can recall them on the road, and the same in the afternoon and evening.In this way, [-]-[-] words a day can be easily memorized.If you need to improve your English quickly, you can also watch English movies or play English songs while memorizing English words. In short, the purpose is not to let the content of learning be single.

Cross memory combined with other methods
(1) Different learning methods of reading, thinking, and practicing should be used alternately, and the mouth, eyes, hands, and brain should use the multi-channel memory method in coordination.Sometimes reciting memories, sometimes recalling memories, sometimes calculating memories, sometimes correcting wrong memories, sometimes arguing about memories, and sometimes copying memories. Of course, the best way to memorize with eyes, ears, mouth, hands, and brain.

(2) Internal storage memory and external storage memory alternate.

Internal storage mainly refers to using the brain as a warehouse, and external storage mainly refers to using materials and reference books, making cards, pasting and paste, and excerpts for memory.Such as card memory method, chart memory method, inductive memory method, etc.

(3) Do frequent recall and try to recall the memory method.

Experiments have proved that the review method of alternating memory and recall is an effective way to improve the review effect.A careful person found that when the Chinese mathematician Chen Jingrun was studying, the lights in his dormitory were on and off.He first opened the book, then turned off the light and lay on the bed to recall and think. When he understood and remembered, he turned on the light and checked it again. read down.So he reads exceptionally well.
