Scientific learning method
It is important to listen carefully in class. On the other hand, it is also important to review in time.
What problems have you found from doing the problem? When you encounter problems you don't understand, you should understand them in time, record the more accurate problems, and review them in time to ensure that you won't forget them.
Mathematical research
The investigation of mathematics is mainly the basic knowledge, and the difficult problems are only synthesized on the basis of simple problems. So the content in the textbook is very important. If you can't master all the knowledge in the textbook, you won't have the capital to learn by analogy.
It's best to preview the contents of the textbook before class, otherwise there is a knowledge point that can't keep up with the teacher's footsteps in class, and the following is unknown. This vicious circle will start to get tired of mathematics, and interest is very important for learning. Targeted exercises after class must be done seriously and not lazy. You can also calculate the classroom examples several times when reviewing after class. After all, in class, the teacher is calculating and explaining problems, and the students are listening. This is a relatively mechanical and passive process of accepting knowledge. Maybe you think you understand it in class, but in fact, your understanding of problem-solving methods has not reached a deeper level, and it is very easy to ignore some difficulties that will inevitably be encountered in the real problem-solving process. A good brain is better than a bad pen. For solving mathematical and physical problems, it is not enough to rely only on the general ideas in the mind. Only through careful written calculation can we find the difficulties, master the solutions and finally get the correct calculation results.
Secondly, we should be good at summarizing and classifying, looking for the * * * relationship between different types of questions and different knowledge points, and systematizing what we have learned. To give a concrete example: in the function part of senior one algebra, we have studied several different types of functions, such as exponential function, logarithmic function, power function, trigonometric function and so on. But comparing and summarizing, you will find that whatever kind of function we need to master is its expression, image shape, parity, increase and decrease and symmetry. Then you can make the above contents of these functions into a big table and compare them for easy understanding and memory. Pay attention to the combination of function expressions and figures when solving problems, and you will certainly get much better results.
Finally, we should strengthen after-school exercises. Besides homework, find a good reference book and do as many exercises as possible (especially comprehensive and applied questions). Practice makes perfect, thus consolidating the effect of classroom learning and making your problem solving faster and faster.
The study of physics
I have heard of the "three-more method" of "understanding more, practicing more and summing up more" summarized by a middle school student in Shanghai. I think this method can summarize the main points of physics learning in senior high school.
Understanding is more about previewing, attending classes and reviewing, and understanding what you have learned from different levels and angles. Preview can be divided into rough reading and intensive reading. Take a cursory look at what you want to learn first, and circle the important parts in the form of subtitles. Then read the circled part carefully and have a deep understanding, that is, intensive reading. In class, you can listen to the teacher explain the difficult points and answer questions purposefully. Only in this way can we understand knowledge more comprehensively and thoroughly. In after-class review, in addition to understanding and memorizing formula theorems, we should also deeply understand the teacher's lecture ideas and the "central idea" of solving problems, that is, grasping the knowledge points of examples and applying formulas of what theorems to make them orderly and procedural.
More practice refers not only to the practice of consolidating knowledge, but also to the "practice" of psychological quality. To strengthen the practice of attention, we should not only complete the exercises in class seriously, but also complete a certain amount of extracurricular exercises. However, simple "sea tactics" is not desirable, and some representative questions should be selected. Students with a good foundation have to do some comprehensive problems and application problems. In addition, Pingyue should pay attention to adjusting the mentality and cultivate a calm and confident psychological quality.
To sum up, we should first classify and sort out the classroom knowledge in detail, especially the theorem, deeply understand its connotation, extension, derivation and scope of application, sum up the relationship between various knowledge points, and form a knowledge network in our minds. Secondly, we should analyze and summarize the solutions to various problems. Another kind of summary is also very important, that is, after the usual practice and examination, analyze your own mistakes and weaknesses in order to overcome them in the future.
Chemical Research
To learn chemistry, we must grasp the foundation, ideas and laws. Paying attention to the study of basic knowledge is the guarantee of improving ability. Learn the basic concepts of chemical terms such as element symbols, chemical formulas, chemical equations and properties of elements and compounds. To do problems, you should be good at summing up the types of questions and solving problems. There are inherent laws between chemical knowledge. If you master the rules, you can control and remember knowledge. Such as the general law of valence, metal elements usually show positive valence, nonmetal elements usually show negative valence, the valence of simple elements is zero, and many elements have valence changes, and the valence States are different under different conditions.
There is a saying about chemistry that chemistry is a liberal art in science. Because chemistry has a lot to remember and is an experimental subject, we should pay attention to the combination of reading, hands-on and writing in the learning process of chemistry. You should deduce, calculate, write structural formulas, write chemical equations, or do experiments yourself to verify, deepen your impression and help you understand. Sometimes you have to look for information and supplement some materials. At the same time, in chemistry learning, it is a basic activity method and a basic method to improve the effect of chemistry learning to put forward the contradictions within or between chemical things after thinking, that is, to study and solve chemical problems by yourself or to ask others for help when they can't solve them.
Biological research
Basic policies:
1. Biology is a subject that correctly understands the body and learns the relationship between man and the environment (plants, animals and nature).
2, don't blindly remember, use the experience in life to understand.
Application scheme
1, carefully understand the textbook content, understand and remember the basic concepts.
(1) Learn with each concept according to the learning objectives of each unit.
(2) Don't just memorize the core questions, but learn them step by step.
(3) We should correctly grasp the meaning expressed by the images, tables and photos in the teaching materials.
2. Combine what you have learned with real life to understand.
3. Compare Japanese common words with scientific words, and remember them after you really understand them.
4. After the content is expressed in figures or tables, it can be sorted out and understood.
5. After the experiment is sorted out, the concept of connection will be understood. Grasp the purpose of the experiment, compare the results with your own ideas, find out the gap and analyze the reasons for the gap.
* correctly understand the structure and usage of the microscope, and directly observe and understand the characteristics of various organisms.
* Get into the habit of keeping an experimental observation diary.
6. Memorize with the explanation part of the learning materials and the arrangement part of the problem set as the center.
7. Memorize in different ways according to the content.
(1) Associate what you have learned and organize your memory.
* Write down the themes that come to mind in any order.
* Write the central theme in the middle position.
* according to the relationship between knowledge, complete the map with lines or charts.
(2) Memorize with words with special meaning or special meaning.
(3) Memory with eyes, hands, mouth and ears at the same time.
8. Problems you don't understand must be solved. Ask yourself questions first, and then ask others if you know what you don't understand. )
9. Confirm what you have learned by solving problems.
(1) sort out the wrong questions and review them before the next exam.
(2) Check textbooks and study materials to find questions that you don't understand.
(3) Do the questions in the order of basic questions-moderately difficult questions-difficult questions, and understand the content.
other
1, when the time is relatively loose, such as holidays, you can start with the part you are interested in. (Related parts can also cultivate interest)
2, usually use the encyclopedia to find things you don't understand.
When your academic performance can't go up, there must be something wrong with the market method. We need to take time to review, improve and correct our learning methods. The breakthrough of our achievements means that we can wait.
