"Three Laws and One Book" Need to Know
A Method of Reading —— Looking at Calligraphy by Catalogue.
Looking at calligraphy by catalogue simply means looking at the catalogue before reading, or reading against the catalogue.
There are not a few people who emphasize the "outline", but few people think that the catalogue of a book is the best outline of this book; A large number of teachers emphasize that students should make an outline of a textbook, but they just didn't expect students to read it against the catalogue. If we use the table of contents to read calligraphy in the process of learning, whether before class, after class or in the general review, we can effectively "check for missing parts" and better understand the true meaning of "outlining".
Look at the calligraphy in the catalogue, and you can also screen some books. When acquiring an unread book or preparing to buy a book, you will get what you need more practically if you pay attention to the preface, abstract, table of contents, etc. Have a general understanding of the contents of the book first, and then consider whether it is necessary to read or buy it.
A memory method-associative memory method.
Associative memory is a way to remember things through association.
Most people use this method consciously or unconsciously, and others, such as comparative memory and story memory, are derived from associative memory.
When we usually talk about someone or something, we always get a hint and have a basic image in our minds, so that we can talk more vividly; When we talk about something we are familiar with, the shape of that thing always comes to mind. These are all conscious or unconscious use of associative memories.
For example, mathematical equations are based on the balance principle of scales. If we connect the equation with the balance, we can deepen our understanding of the equation. Many experiments in physics, chemistry and biology, if done by yourself, will be unconsciously associated in the learning process; In the study of biology, if you pay attention to observation at ordinary times, you can also associate it well; The memory of historical events and the determination of geographical location all need to use "association"; In the process of learning a foreign language and Chinese, especially when collecting and memorizing foreign language vocabulary, idioms and Chinese good words and sentences, association is more necessary.
If we continue to "associate" and form the habit of using associative memory, we will benefit a lot.
A way of thinking-"logical" thinking.
Logical thinking is the abstract thinking of human beings.
It is a thinking process from intuitive perception to image understanding, and then to abstract exploration of the objective world through concepts, judgments, reasoning and argumentation.
Logic has two meanings at different levels and angles: first, logic is a sequence and a law; Second, logic needs to be classified and then summarized. When a person does something or speaks upside down, it is usually said that the person has no or lacks "logic".
To put it bluntly, logic is to do things in an orderly way.
Mathematician Hua's "overall planning method" can make people understand what "logic" is To improve logical thinking ability is to think of "overall planning method" at every turn and develop the habit of doing things in an orderly way at ordinary times.
Other thinking methods, such as habitual thinking, extended thinking and reverse thinking, are basically derived from logical thinking methods.
Teachers who can't talk-reference books.
Reference books are documents specially designed for finding knowledge and information. Commonly used reference books include Xinhua Dictionary and English-Chinese Translation Dictionary.
These extremely rich reference books will bring extremely rich gains and greatly stimulate the interest in learning. If you know the "three methods and one book" and can improve your ability in all aspects accordingly, it will lay a solid foundation for systematic learning.
The classroom effect is particularly important.
The learning effect in the classroom is particularly important. How to avoid poor learning effect caused by inattention in class? In fact, many adults can't concentrate for 40 minutes, and it is almost impossible to emphasize that 40 minutes in class is not absent-minded. If you do this:
First, preview before class and write down what you don't understand.
Second, in class, teachers listen carefully to what they don't understand.
Third, in case you miss the key points because of desertion, review your homework carefully after class and then write down what you don't understand.
Fourth, the teacher will talk about what he doesn't understand and focus on listening.
This repeated cycle can effectively avoid the problem of poor learning effect caused by inattention in class.
It can be summed up in one sentence: "I don't understand in preview, and I don't understand in class." When you miss something, you can't find it in the review; Focus on listening to' I don't understand' and listen to' I don't understand' repeatedly. "
Basic knowledge is the most important.
Basic knowledge is the most important! Most basic knowledge comes from textbooks. Textbooks are the crystallization of human collective wisdom and the essence of essence.
Don't look at things that are not sure about the right thing over and over again. Only those things that are definitely right are worth remembering. The correct rate of the content in the textbook is infinitely close to 100%, so we repeatedly emphasize the principle of taking books as the foundation-attach great importance to the textbook!
If you forget what you have learned before, don't be afraid to look back at your previous textbooks.
The study of basic knowledge is a repetitive process, and it is a process of "learning textbooks repeatedly". To lay a good foundation is to "thoroughly" the textbook.
If you can do it: even if you wake up in the middle of the night, you can still answer the main points of knowledge skillfully. Your academic performance must be excellent.
Mathematics and physics gave birth to "one reason"
Some concepts, such as definitions, axioms, laws, theorems and inferences in mathematics, science, culture and life, belong to basic knowledge and are closely related to Chinese. If you can't understand or remember the concept, then the teacher is like listening to a gobbledygook. Of course you can't learn well. If you can understand or remember the concept (you can't really understand it yet, don't imitate rote memorization), then when the teacher lectures, think about it: "Why did the teacher do this, what concept did he use, and where did he cut in?" Verify the basic concepts you understand or remember with what the teacher said, in turn, deepen your understanding and memory of the basic concepts, and draw inferences from others (generally speaking, it is enough to listen carefully to the teacher's comments on 10 sets of handouts or test papers). Therefore, it is very important to understand and remember the concepts in mathematics, science, culture and life.
Mathematics: the concepts of three elements of number axis, fraction, equation, image of function, translation, permutation and combination. , almost runs through a person's life from contact with these concepts. Mathematics is also related to physics and other disciplines, such as equations and equations, which are all based on the balance principle of physics.
Physics: Force analysis almost runs through physics study. Physics and mathematics are closely related, for example, the three elements of force are very similar to the number axis; Verifying physical experiments and solving many problems such as lever, light and electricity require mathematical knowledge.
Chemistry: it is a liberal arts in science. Almost all chemical reactions are related to the arrangement of extranuclear electrons, so we must master the knowledge related to the arrangement of extranuclear electrons. Solubility tables of some acids, bases and salts are very common and important in chemical learning and daily life, so the periodic table of elements and solubility tables of some acids, bases and salts should be memorized and memorized. Experiments are also important. If possible, it is best to do experiments by hand and remember the experimental phenomena. Chemistry has many connections with mathematics, physics and other disciplines. For example, the calculation in chemistry is inseparable from mathematical knowledge; The burning of candles includes chemical and physical reactions; Colloidal aggregation is a physical change and so on.
Biology: Anatomy can have an intuitive understanding of biology and deepen the understanding of textbook knowledge. Whenever possible, pay attention to observation: grass sprouts, seedlings grow, ants climb trees, hens lay eggs, cats and dogs give birth, pigs and sheep are slaughtered, and so on. It's not like you want to eat and buy a chicken to kill yourself. Biology is closely related to mathematics, physics and chemistry. For example, photosynthesis and transpiration of plants need to be explained by relevant knowledge.
To learn math, science, chemistry, health and other subjects well, you don't have to do many problems. I am most afraid that I am right and I don't know where I am right. I'd rather do something wrong and know where it is. On the basis of understanding the concept, do some targeted exercises properly, and the academic performance of mathematics, science and health will be sharp.
