1. The purpose of memory is application.
The human brain should not compete with the computer for memory. The purpose of our memory is not to challenge our own memory, but to help us solve the problems in the college entrance examination or other practical problems. Remember what is meaningful, not what is meaningless.
Don't be superstitious about some fancy memory skills. For example, it is meaningless to use "homophonic method", "graphic method" or any other method to remember dozens of digits behind pi. With this time, it is better to solve more math problems, which is more helpful to improve math scores.
2. Decide the focus of memory according to the use of knowledge.
Not everything that needs to be remembered must be remembered clearly to be "remembered". As long as we get what we want by carrying something, we will be "remembered".
The purpose of memorizing scientific formulas such as mathematics, physics and chemistry. The problem is solved by calculation, so the key is to know its context and use it flexibly; China's poems and paragraphs focus on understanding their structure and writing style, which can only be used for reference when writing. As for individual words, it doesn't matter if there is a little mistake in memory. The memory of historical and political knowledge focuses on remembering the context of historical events and the logical structure of political theory, which can be used when analyzing and answering questions. As for the specific expression, you don't need to memorize it word by word; Reciting English articles focuses on deepening the understanding of words, grammar and sentence patterns. It doesn't matter if you forget after reciting the article, just remember the useful grammar and sentence structure in the article.
Only what you really understand can be remembered.
Memory =90% understanding+10% reciting. You must spend more time on understanding rather than reciting, so that learning can be efficient. Without rote memorization based on understanding, there will only be two results: one is to remember slowly and forget quickly; Second, remember quickly and forget faster.
If some knowledge is painful to remember, or it is constantly remembered and forgotten. The first thing to doubt is not your IQ, but whether you have a thorough understanding of this knowledge.
Thorough understanding refers to understanding the process rather than remembering the results.
Within a piece of knowledge, if you know the connection between the simplest concept and the most complex content, then you have a thorough understanding of this piece of knowledge. It emphasizes the process, not the result.
When reviewing analytic geometry, you can ask yourself: "What is the simplest concept of analytic geometry?" Then ask yourself: "What parts of geometry do I find most difficult and confusing?" Then, you try to deduce the most difficult and complicated knowledge points step by step from these simplest concepts in various ways. As long as you make this process clear, then these difficulties will be thoroughly understood for you. This method is useful for any kind of conventional knowledge.
Grasping the law of knowledge can make memory get twice the result with half the effort.
On the basis of thorough understanding, grasping the laws of knowledge can make our memory get twice the result with half the effort. The method of finding the law will be explained in detail through a series of examples.
