What to do if you forget what you have learned

How to improve memory efficiency.

Memory is of great significance in people's lives, as the saying goes: "Memory is the warehouse of people's hearts". This shows that any normal person cannot do without memory at any time, especially for students, memory is even more important.

So how can you improve memory efficiency?

First, it's important to understand the optimal memory conditions. In order for a person to have a good memory and a high memory efficiency, he or she must have the following conditions:

Focus.

Attention is a necessary condition for the success of memory, the beginning of all cognitive processes, and the gateway to the mind. From a psychological point of view, when studying, attention is concentrated, brain cells have strong excitement, deep impression of things, and easy to remember.

Memorize with clear goals.

The clearer and more specific the goal of memory, the better the effect of memory. Psychological experiments have shown that two groups of students read a text at the same time, and asked group A to memorize, but group B did not ask for anything, and the result was that group A's memorization efficiency was twice as high as that of group B. Therefore, when studying, forcing yourself to remember what you should remember, and insisting on not forgetting it, will achieve the best memory effect.

Rich experience.

There is a transfer theory in psychology that learning one knowledge or skill has an impact on another. This law tells us that rich experience plays an important role in improving memory efficiency. As the saying goes: the more you use your brain, the smarter you are, and the more you don't use it, the more stupid you get.

Pleasant and stable mood.

Emotional stability is the key to memory, imagine a person who has just become angry with someone else, and when his emotions are extremely unstable, let him remember certain materials, then he can't remember anything. When the activity of the cerebral cortex is stable, it is easy to receive incoming information from the outside world and form clear memories.

Proper nutrition.

Studies in brain physiology have shown that memory is related to the content of the neurochemical choline acetate in the brain, which is mainly found in fish, meat, and eggs.

Reasonable rest.

Excessive fatigue can impair the activity of brain cells and even lead to insomnia and memory loss. Therefore, when studying, we should combine work and rest, learn to rest, learn to use our brains, and avoid "driving at night".

Remember to have a positive attitude.

The effect of memory is different depending on the level of motivation and sexuality. Therefore, the material that has been memorized can be classified in some way. Finding out between them, or making them into outlines, drawing charts, and compiling them into smooth mouths, etc., can improve the efficiency of memory.

Organisation of the material.

Psychological experiments have shown that the content of memory can never fill the brain, but the amount of information received by the brain generally does not exceed seven units during a short period of memory activity. However, these "seven" can be seven single entities, seven words, or seven blocks composed of many single individuals. Therefore, organizing the material can increase the memory capacity and improve the memory efficiency.

If it's important, then go back and remember it a few more times. If it's just a general thing, forget it, and it will also help reduce the load on the brain.

It may be because you are not particularly familiar with this knowledge point in the process of learning. Taking liberal arts as an example, most students know that liberal arts just need to be memorized.

In fact, rote memorization is outdated, even if it enables you to memorize by rote, it will also be forgotten in a short time. Therefore, the correct way for liberal arts students to memorize is: first understand... If you memorize the formwork beam on the basis of the Tangerine Solution, you will find that the rate of forgetting will be greatly slowed down.

I... A genius is the one who repeats the most.

This is not a problem of a few people, nor is it a problem of intelligence, the main reason is that the learning method is not appropriate, and the effort is not used to the idea.

From the beginning of admission, there is a student code of conduct that requires students to listen carefully in class. Therefore, the knowledge learned through listening to lectures in class cannot be regarded as the scope of active learning of students, and this process is still passively receiving the knowledge instilled by the teacher.

If you only rely on the time in class to understand that knowledge, without any other active learning, the content memorized in 45 minutes of class will be quickly forgotten, and relevant data show that the knowledge retention rate achieved through listening to lectures may only be about 5%.

Therefore, we have the learning habits of reviewing knowledge after class, practicing and filling in the gaps. In other words, learning is divided into passive learning and active learning, and if you want to consolidate the knowledge you have learned, you must have an active learning process.

It's normal to forget what you've learned quickly, and you want to remember itAfter learning and memorization, "spaced repetition" and "retrieval memory" are performed according to the forgetting curve (regularity).

Spaced repetition refers to the repetition of timed intervals according to the law of forgetting, usually in a day, a week and a month, and the frequency of repetition should be adjusted according to the purpose of your memory and how long you want to remember. Retrieval memory refers to learning or consolidating memory, not just reading once, but "extracting" the content through some somewhat difficult methods. For example:

Write the answer on one side and the answer on the other, and when you search, look at the question and recall the answer. Recall thoughts, and after reading the content, recall what you watched in your mind or on paper. Questioning, such as designing some questions after reading a book or studying a chapter, and testing your mastery of knowledge through questions.

Mind mapping method, for example, after reading a book, sort out the main content into a mind map, and then recall the content of the book through the "keyword index" in the mind map in the "interval review and memory time period".

Secondly, imagination is the source of a lot of memory, and the more vividly you imagine, the easier it is to remember. There is a way to find imagination, simply put, it is to encode those meaningless numbers or words to be memorized through "homophony, image transformation, and meaning transformation", so as to better complete the memory. In the "Elite Speed Reading Memory Training Software", the encoded memory is divided into three specific types: "digital coding, human body coding, and furniture positioning (location memory and palace memory)".

For example, the number encoded in the software is divided into "0 to 9" and "00 to 99", a total of 110, as long as the 110 numbers are encoded and memorized, no matter how long the number is, you can remember it. In the future study, whether it is numbers or words, you can flexibly switch according to the actual situation and actual needs, so as to better remember.

Third, knowledge should be correlated. Correlation is an attempt to connect new knowledge with what is already known. In this way, when learning something new, it is not about learning a completely unfamiliar concept, but only about understanding the difference from what you already have.

For example, use "This is the same as ......"The mentality of learning; Tell yourself that "this is just an extension of the concept". This allows us to understand what we have learned more quickly, allowing the brain to remember more information and reducing the burden on memory.
