Percentage of forgotten time intervals

20 minutes 58% 42%

1 hour 44% 56%

8 hours 36% 64%

1 day 34% 66%

2 days 28% 72%

6 days 25% 75%

3 1 day 2 1% 79%

It can be found that the fastest forgetting speed is 20 minutes, 65 hours, 438+0 hours and 24 hours respectively, and the forgetting rates are 42%, 56% and 66% respectively. The forgetting rate of 2-3 1 day is stable between 72% and 79%; The speed of forgetting is fast first and then slow. Through analysis, it is obvious that the best time for review is 65438+ 0-24 hours after memorizing the materials, and no later than 2 days. A little review of this section will restore your memory. When we review our lessons, we sometimes feel as if we have encountered new knowledge. This is because the interval between reviews is too long. We should consciously apply this rule in the future, and never think that reviewing at any time is the same. After waking up before going to bed-the golden time of memory-the time before going to bed can be mainly used to review what you have learned during the day or before. According to Ebbinghaus's forgetting law, you can keep 34% of the information you have contacted in 24 hours. At this time, a little review can restore your memory. Moreover, because it is not affected by backtracking inhibition, memory materials are easy to store and will be transferred from short-term memory to long-term memory. In addition, according to research, memory does not stop during sleep, and the brain will summarize, sort out, encode and store the information just received. So the time before bed is really precious. After getting up in the morning, because I won't be affected by proactive inhibition, I will remember new content or review what I reviewed last night, and I will remember it all morning. So don't waste this time before going to bed after waking up. If we make full use of it, we can get twice the result with half the effort. Reviewing and Revising the Past —— An Ancient and Practical Memory Skill

We are familiar with the words "review the past and learn the new" and "read a book a hundred times and you will understand your meaning". Indeed, review is the mother of memory, and the best way for us to consolidate what we know and remember is review! Memory is the process of forming temporary neural connections in the cerebral cortex. If the established neural pathway is not smooth, the traces left in the original brain will gradually disappear, and review is to stimulate the traces in the brain again. Timely review is to repeat the second and third stimuli when the traces of the first time have not completely disappeared. The more repetitive stimuli, the deeper the trace. The more timely the repetition, the less time and energy it takes, and the better the memory effect. Skeleton and subtlety

The content of skeleton column is not easy to forget, but it is easy to forget directly and imperceptibly.

Inspiration: learn to summarize and summarize the main idea to remember when learning. We should grasp the framework, structure, organization and general significance of what we have learned from a macro perspective.

Does it make sense?

Meaningful, understandable, not easy to forget, meaningless, incomprehensible, easy to forget.

Inspiration: When studying, it is understandable to remember what you want to remember. If what you remember is meaningless, you can creatively give it meaning.

Hobbies and interests

Content with interests, hobbies and needs is not easy to forget.

Inspiration: cultivate interest in what you remember when you study. To understand why I want to learn these contents, what good is it for me to learn these knowledge? Content and time

It's easy to forget too much content of the same kind at a time for too long.

Enlightenment: We should pay attention to the alternate study of arts and sciences and different disciplines when studying. Because the knowledge of forgetting laws of different disciplines is in charge of different parts of the brain, alternating learning of disciplines can make all parts of the brain get timely repair. Middle, front and back

Intermediate materials are easy to forget, and the contents at the beginning and end are easy to remember.

1, proactive inhibition: the content of previous memory has an inhibitory effect on the content of later memory;

2. Post-action inhibition: the content memorized later will affect the memory effect of the content memorized earlier.

Inspiration: Learn the content to be memorized in sections, add multiple beginnings and endings, and enhance memory efficiency. Learning important content after getting up or before going to bed can reduce the influence of proactive inhibition and proactive inhibition and increase the effect of pre-memory.

Human condition

Memory efficiency is low when brain function declines due to excessive brain use.

Revelation: combine work and rest, don't study in a state of fatigue. After studying for forty or fifty minutes, we should do broadcast gymnastics and eye exercises. These exercises will certainly benefit your physical and mental health and improve your learning efficiency. You can't take them for granted. Regular review and self-test

That is to make a review self-test plan for the courses and knowledge learned, and then implement it on time.

① Daily test: Before going to bed every night, repeat the main points of what you learned that day. If conditions do not allow, you can write an outline silently, or simply meditate.

② Weekly test: You can ask questions from another angle on Sunday, write them on a piece of paper and test them yourself. If you find any problems or ambiguities, solve them immediately and never delay.

Unit test: after learning a unit, you can test what the main content of the unit is and what you gain after learning, so as to digest it in time and consolidate your memory.

4 Book test: After learning a book, you can open the table of contents and recall the contents one by one. On the basis of unit testing, book testing is not a big problem. If you don't have time, you can choose those important contents first.

Test at any time

This means testing yourself anytime, anywhere.

This method is very effective in learning foreign languages. Prepare some cards first, write five foreign words on the front and five corresponding Chinese words on the back, and put them in your pocket to test yourself at any time. There are two methods of self-test: ① Reading aloud: you can read Chinese in a foreign language, and you can also read Chinese in a foreign language without disturbing others. When you really can't remember, turn it over and recognize it. (2) Learning to write: Learning a foreign language is difficult to remember without writing, and it is impossible to translate without practicing writing. You can look at the Chinese on the card and write the corresponding foreign words. However, many occasions are not allowed to sit down and write. What should we do? I suggest you try the following methods: when listening to the report in the auditorium, before the meeting, at the bus stop, when waiting in line in the store, write in the air with your fingers down. You can test yourself at any time without a card. When you see something, try to express it in a foreign language or meditate in your mind. This not only uses the time, but also receives the good effect of decentralized review.

Review and self-test methods

1. Try to recall: Try to recall what you have learned in your mind. Some people call it "watching movies", which is a way to force yourself to concentrate. Psychological experiments show that it is better to try to remember than to remember repeatedly. The more time you spend on memory, the better your grades will be. Specifically, after reading or reading aloud to a certain extent, you forget the rules, close the book and try to remember, and immediately check the ambiguous places with the original text. You can also try to remember the specific content that should be remembered for a period of time after reading. At this time, the experimenter will be in a positive mental state, not only paying attention, but also full of interest. At the same time, after proofreading and verification, I can know my weaknesses in time, so that I can concentrate on memorizing unfamiliar materials.

2. Talk and debate: that is, debate and discuss what you have learned.

Zhuangzi said: "What you know is indisputable", which is very reasonable. Debate aims at expounding one's own views and explaining objective things and phenomena. When talking, we should understand each other's point of view and get inspiration from it; When arguing, it is easy to expose the weak links in your knowledge structure. In the process of talking and arguing, both sides will deepen their impressions, the mistakes will be corrected, the right ones will be admitted, and the memories will be consolidated. In addition, personal contact is always limited. Through conversation and debate, we can broaden our horizons, brainstorm and increase our knowledge and talents.

Many celebrities are willing to talk and argue. When Einstein began to delve into learning, he often talked and argued with friends like Solowan and Habicht. With the help of friends, Einstein mastered Riemann geometry, which laid the foundation for the theory of relativity. They called the place where they talked and argued "Olympia Academy of Sciences". Conversation and debate are effective means to test yourself, train your thinking and deepen your memory. Ask and answer questions

"If I were a teacher, how would I test my students? What points do I want students to master? " If you often ask yourself some questions and answer them from all angles, you will get unexpected results.

Najia Mahwa, a student in Sverdlov Village, Moscow State, Soviet Union, often assumes that she is a teacher, prepares teaching notes, writes down a list of students on it, plays the role of students to answer questions, and grades each answer. After such a period of time, Najia found: "In the past, geography class was like hard labor for me. Now, as soon as I come back from school, I want to finish my homework at once, so that I can study geography. Why is this? Because when I do this, I think, I am a teacher, not a student, so I am interested ... In order to keep my interest in geography from weakening, I will insist on making teaching notes for one year. " Self-testing and asking questions is a major problem. We must always consider the form, angle and requirements of asking questions, so as to be effective. Try to talk to others

To be a teacher, be a student first. When you are ready to tell others, you must first understand. Lev tolstoy once said: "Only knowledge acquired through positive thinking rather than memory is real knowledge." The process of preparing a speech is the process of using this positive thinking. If you want to tell others, you should use your own language in most cases, and you can't follow suit. This requires us not only to know why, but also to know why, not only to master knowledge comprehensively and skillfully, but also to express it in our own words. Trying to tell others is forcing yourself to understand those specious problems, so that your memory can be consolidated and enhanced. 5. Practical testing

The knowledge often used in work and life is memorable. From the perspective of neurophysiological mechanism, the more frequently knowledge is used, the deeper the traces left by the cerebral cortex and the stronger the temporary neural connection. The more times it is used, the conditioned reflex of the second signal system will closely link the abstract information symbols memorized by learners with the corresponding practical activities, and the memorized information will be easily extracted. Revelation 1: After learning the materials that must be remembered, arrange the first round of review at the first time, and arrange the follow-up review in time.

Revelation 2: First, don't have too much material for one memory. According to later research, it is most appropriate to arrange a group of memory materials around seven o'clock. Second, actively seek the connection between "materials that need to be memorized" and efficiently complete the work that must be done well through understanding; Third, refuse to learn by rote.

Revelation 3: For those seemingly independent memory materials, we can help to remember them by arranging stories and associating them.

Enlightenment 4: Strive to improve the motivation of learning and make memory materials become the materials that students need and are interested in.

In addition, everyone's memory has its own characteristics. We should find our own Ebbinghaus memory curve according to everyone's different characteristics, and constantly improve the efficiency of learning.
