For teenagers and middle school students, you can refer to these 8 methods to improve memory:

1. Concentrate when memorizing. When remembering, as long as you concentrate, concentrate, and eliminate distracting thoughts and external interference, the cerebral cortex will leave deep memory traces and make it difficult to forget. If you are distracted and multitasking, your memory efficiency will be greatly reduced.

2. Understanding is the basis and key of memory. The efficiency of rote memorization is very low. Only when you understand something can you remember it firmly and for a long time. If you want to better understand knowledge, you need to read more, think more, ask more, associate more, and do more questions.

3. Review the knowledge learned and memorized in a timely manner. The speed of forgetting is fast at first and then slows down, so for the knowledge you have just learned, you should strike while the iron is hot, review and consolidate it in time, strengthen the memory traces, and prevent excessive forgetting. The specific time period is measured according to your actual situation and combined with the forgetting curve.

4. Frequently recall and retrieve. For example, after finishing studying, close the book and try to recall the content, and then flip through the book to look at unfamiliar places; after a period of time, conduct self-tests, Q&A, etc.

5. Combine reading, thinking, seeing, listening and writing. That is to say, seeing with the eyes, reading with the mouth, listening with the ears, thinking with the brain, and writing with the hands, it is better to combine multiple senses to memorize. For example, when memorizing words, you can read, think, and write at the same time.

6. Use a variety of memory methods. Depending on the situation, flexible use of classification memory, characteristic memory, homophone memory, argument memory, associative memory, interesting memory, chart memory, card memory and other methods can enhance memory. For example, the encoding and positioning memory in the "Elite Speed ??Reading and Memory Software" uses methods such as homophony, image transformation, meaning transformation, and staking. The mind map memory uses keyword memory, sorting and classification, and other memory methods. This will make it much easier to remember.

7. Grasp the time period when your memory is good. Generally speaking, 9 to 11 a.m., 3 to 4 p.m., and 7 to 10 p.m. are more suitable for memorization and recitation (the specific time will vary from person to person). It is better to use the above time to memorize difficult-to-remember learning materials.

8. Use your brain scientifically. On the basis of ensuring nutrition, rest, physical exercise, etc. to maintain the brain, using the brain scientifically, preventing excessive fatigue, and maintaining an optimistic mood can greatly improve the brain's learning and memory efficiency.
