Tell me some tips and tricks directly. ) 1, take math notes, especially the different aspects of concept understanding and mathematical laws, as well as the extra-curricular knowledge added by the teacher to prepare for the college entrance examination. 2. Establish a mathematical error correction book. Write down error-prone knowledge or reasoning in case it happens again. Strive to find wrong mistakes, analyze them, correct them and prevent them. Understanding: being able to deeply understand the right things from the opposite side; Guo Shuo can get to the root of the error, so as to prescribe the right medicine; Answer questions completely and reason strictly. 3. Memorize mathematical laws and conclusions. 4. Establish a good relationship with classmates, strive to be a "little teacher" and form a "mutual aid group" for math learning. 5. Try to do extra-curricular math problems and increase self-study. 6. Repeatedly consolidate and eliminate forgetting before school. 7. Learn to summarize and classify. Ke: ① Classification from mathematical thoughts, ② Classification from problem-solving methods and ③ Classification from knowledge application.

geography

Mainly divided into nature, humanities, regional geography, land consolidation, learning geographical maps is very important. 1, to study physical geography and the earth, you have to remember some pictures of the earth's rotation and revolution in the spring and autumn equinox, which is the best to understand. Personally, I think this part of science is a bit difficult to understand and I need to understand it myself. Then the atmospheric ocean currents should be remembered and understood. In fact, atmospheric circulation and ocean currents are interlinked. I remember that the teacher emphasized the difference of thermal properties at that time, because it was the root of air flow. These are also quite difficult to understand. The last class is often not enough, you have to think for yourself. 2. What human geography doesn't say is to rely on one's own back. Then the teacher's notes are very important. Combining maps and notes will get twice the result with half the effort. Remember those words and write more by yourself. It's relatively easy to earn points. 3. Regional geography is absolutely necessary for remembering maps. First of all, you should print the latitude and longitude of the earth in your mind, and then you have a good positioning of the five continents and four oceans. For example, Europe is about 10W~60E 35N~70N. Is to print the map of the whole world in your mind, and then gradually refine it to clarify the nature and economy of each region. It is best to memorize the famous local cities, topography, rivers, minerals, biology and geology to form a framework. These may be test sites. In the final analysis, regional geography is comprehensive and needs the foundation of physical geography and human geography in the early stage, so the foundation must be solid. 4. Land consolidation should also be backed, and rules and regulations should also be backed. In fact, this part of regional geography and physical geography will bring some. In a word, it is very important to study geography and maps. At the beginning, the teacher suggested that you should look at the pictures if you have nothing to do, and then focus on understanding. After all, geography is a science in universities. Listen carefully in class, and it is best to digest it in class. The number of questions is also indispensable, and the difficulty of the questions is moderate. Don't always do strange questions and digressions, but draw inferences from one instance to another.

Physics:

Compared with junior high school physics, senior high school physics has more contents, greater difficulty, higher ability requirements and greater flexibility. So many students are very uncomfortable after entering high school. After entering the first year of high school, there is no problem with the movement of forces and objects for the time being. I think high school physics is like this. After learning Newton's laws of motion, the problems began. The problems of curvilinear motion, law of universal gravitation, momentum and mechanical energy became more and more serious. If we don't change our learning attitude and methods in time, physics will get worse and worse. When it comes to physics, we will have a headache, hate physics more and more, and gradually become insulated from it. This makes it difficult for some students who learn physics well in junior high school to adapt quickly after high school. The following are some views and suggestions on how to learn physics well in senior high school.

First, we should change our ideas. Physics in junior high school is good, but physics in senior high school is not necessarily good. Junior high school physics knowledge is relatively simple, with little content and easy to master. In addition, in the late third grade, through a lot of practice and repeated intensive training, proficiency has been improved, which can greatly improve physical performance. But high marks do not mean that you can learn physics well and learn physics. If you don't cultivate your interest in learning physics and don't have good learning methods, it is difficult to learn physics well in high school. Therefore, we must first change our concepts. If we learn physics well in junior high school, we may not learn well in senior high school. So lower the starting point and start from scratch.

Second, we should cultivate a strong interest in learning physics. Interest is one of the driving forces of thinking, a powerful and lasting driving force for learning, and a potential driving force for learning physics well. There are many ways to cultivate interest. From the students' point of view, it should be noted that physics is closely related to daily life, production and modern science and technology. There are many physical phenomena around us and we use a lot of physical knowledge. For example, when speaking, the vibration of vocal cords forms sound waves in the air, and the sound waves reach the ears, causing the eardrum to vibrate and produce hearing; Atmospheric pressure is helpful when drinking boiled water, drinks and dipping a pen in ink. When walking, the static friction between the foot and the ground is helpful, and the walking process consists of continuous dumping action; Remove impurities from rice when washing rice and use buoyancy knowledge; A straight chopstick is inserted obliquely into the water, and it seems that the chopsticks are curved on the water surface; The formation of lightning and so on. Consciously connecting with physical knowledge in practice and applying physical knowledge to practice let us know that physics is so closely related to us that it is useful. Can greatly stimulate the interest in learning physics. From the teacher's point of view, we should introduce the concepts and laws of physics through vivid practical examples and intuitive experiments that students are familiar with, organize students to carry out experimental operations, and let students feel the close connection between physics and daily life; Combined with the content of the textbook, introduce the history and progress of physics and its wide application in modernization to students, let students see the use of physics, and make it clear that today's study is for tomorrow's application; According to the content of the textbook, students are often selectively introduced to some vivid physical allusions, anecdotes and mysterious stories of Chinese and foreign physicists exploring the physical world; According to the teaching needs and students' intellectual development level, some interesting and thoughtful questions are put forward. Teachers' efforts from these aspects can also make students have a passive interest in physics and stimulate their enthusiasm for learning physics.

Third, in the classroom, improving listening efficiency is the key. During study, time in the classroom is very important. So the efficiency of class determines the basic situation of learning. To improve the efficiency of lectures, we should pay attention to the following aspects:

1, preview before class can improve the pertinence of listening. The difficulty found in the preview is the focus of the lecture; We can make up for the old knowledge that we have not mastered well, learn new knowledge, reduce blindness and passivity in the process of listening to lectures, and help improve classroom efficiency. After preview, comparing and analyzing the knowledge you understand with the teacher's explanation can improve your thinking level, and preview can also cultivate your self-learning ability.

2, in the process of listening to lectures, we should concentrate, concentrate, and not be absent-minded. Concentration is to devote yourself to classroom learning, so that you can hear, see, feel, speak and touch. If you can achieve these "five goals", your energy will be highly concentrated, and all the important contents learned in class will leave a deep impression on your mind. Make sure you can concentrate on the class and don't be distracted. Be sure to pay attention to the ten-minute break before class, and don't do too intense exercise or debate, or read novels or do homework, so as not to be breathless, daydreaming, unable to calm down, or even start to sleep. Therefore, we should make material preparation and mental preparation before class.

Pay special attention to the beginning and end of the teacher's lecture. At the beginning of a teacher's lecture, it is generally to summarize the main points of the last lesson and point out the content to be talked about in this lesson, which is a link to link old knowledge with new knowledge. Finally, he often summarizes the knowledge in a class, which is very general and is an outline for mastering the knowledge and methods in this section on the basis of understanding.

4. Take notes. Taking notes is not a record, but a concise record of the key points and difficulties in the above lectures, and recording the main points of the lectures and your own feelings or innovative ideas. In order to review digestion.

5. We should carefully examine the questions, understand the physical situation and process, pay attention to the ideas of analyzing problems and the methods of solving problems, and stick to it, we will certainly be able to draw inferences from others and improve the ability of knowledge transfer and problem solving.

Fourth, do a good job in reviewing and summarizing.

1, review in time. On the second day after class, you must do a good job of reviewing that day. An effective way to review is not only to read books and notes over and over again, but also to take retrospective review: first, combine books and notes to recall what the teacher said in class, such as the ideas and methods of analyzing problems (you can also write them in a draft book while thinking), and think as completely as possible. Then open the book and notebook, compare and make up what you don't remember clearly, so as to consolidate the content of the class that day, check the effect of the class that day, and put forward necessary improvement measures for improving listening methods and improving listening effect.

2. Review these chapters. After learning a chapter, you should review it in stages, and the review method is the same as timely review. We should review by recalling, and then compare books and notes to make its content perfect, and then do a good job in the general part of the chapter.

3. Make a chapter summary. The chapter summary should include the following parts. Knowledge network in this chapter. Main contents, theorems, laws, formulas, basic ideas and methods of solving problems, conventional typical problems, physical models, etc. Self-experience: In this chapter, you should record the typical problems you did wrong, analyze their causes and correct answers, and record the most valuable ideas or examples in this chapter, as well as the unsolved problems, so as to make up for them in the future.

4. Do a comprehensive review. In order to prevent the previous knowledge from being forgotten, every once in a while, it is best not to exceed ten days, and review all the previous knowledge, which can be done by reading books, taking notes, doing problems, reflecting, etc.

Fifth, correctly handle the exercises.

Many students pin their hopes of improving their physics scores on a large number of problems and sea tactics. This is inappropriate. "Don't judge heroes by how many questions they do." The important thing is not to do more questions, but to achieve high efficiency and goals. The purpose of doing the problem is to check whether the learned knowledge and methods are well mastered. If you don't master it correctly, or even have deviations, the result of doing so many questions is to consolidate your shortcomings. Therefore, we should do a certain amount of exercises on the basis of accurately mastering the basic knowledge and methods. As for the intermediate questions, we should pay attention to the benefits of doing the questions, that is, how much we have gained after doing the questions. This requires some "reflection" after doing the problem, thinking about the basic knowledge used in the problem, the main knowledge points, the physical laws used, whether there are other solutions, and whether the analytical methods and solutions of the problem have been used in other problem solving. If you connect them, you will get more experience and lessons. Of course, it is impossible to form skills without a certain amount of practice (homework assigned by the teacher), and it is also impossible. In addition, whether it is homework or exams, we should put accuracy first and methods first, instead of blindly pursuing speed, which is also an important aspect of learning physics well.

6. Pay attention to observation and experiment.

Physical knowledge comes from practice, especially from observation and experiment. We should carefully observe physical phenomena and analyze the conditions and causes of physical phenomena. It is necessary for physics students to do experiments well, learn to use instruments and process data, and understand the basic methods of studying problems with experiments. We should consciously improve our observation ability and experimental ability through observation and experiment. In short, as long as we are open-minded, eager to learn, proactive, practical and serious, work hard to understand knowledge, think more, study more, stress scientific learning methods, connect with life and production practice, and pay attention to the application of knowledge, we will certainly learn physics well in senior high school.

Chemistry:

Talking about chemistry is a fascinating subject. However, because high school chemistry is complicated, difficult and chaotic, many students find it difficult to learn it. So how can we learn high school chemistry well? First of all, we need to understand two characteristics of chemistry-emphasizing experiments. The formation and development of chemistry originates from and depends on experiments, and it is a natural science based on experiments. Therefore, the attention to experiments will be higher than other disciplines. Complicated and complicated. This actually embodies the characteristics of many and scattered chemical knowledge points, and there is a lot of knowledge to be memorized.

Therefore, learning chemistry can not copy the previous methods of learning mathematics and physics, but should be selected and innovated according to the characteristics of chemistry.

(1) observation is observation.

Pavlov, a famous physiologist in the former Soviet Union, wrote six thought-provoking characters on the wall of his laboratory-observation, observation, observation! In chemical experiments, it is one of the important conditions to cultivate our good observation habits and scientific observation methods. So how to observe the experiment? First of all, we should pay attention to overcome the curiosity and interest of observation, make clear what to observe and why to observe, and observe the experimental phenomena in a planned and purposeful way under the guidance of teachers. Observation should generally follow the order of "before reaction-during reaction-after reaction", such as heating basic copper carbonate in a test tube to observe whether new substances are generated after heating changes of basic copper carbonate; The contents and methods of observation are as follows

Before (1) reaction: basic copper carbonate is a green powdery solid;

(2) During the reaction: the condition is heating, and the phenomenon in the changing process is that the green powder gradually turns black, water mist gradually forms on the test tube wall, and the clarified lime water gradually becomes turbid;

(3) After the reaction: all the green powder in the test tube turns black, water drops are generated on the wall of the test tube, and all the clarified limewater is turbid. Analysis shows that basic copper carbonate is heated to generate new substances, such as black copper oxide, water and carbon dioxide. Finally, by comparing the previous three experimental phenomena, the concept of "other substances are produced when changing, and this change is called chemical change" is summarized.

(2) Active hands-on experiments. This is also a kind of ability that students must form, which is clearly stipulated in the syllabus. As the saying goes, "Love at first sight is not as good as love at first sight". Hands-on experiments can not only cultivate our hands-on ability, but also deepen our knowledge, understanding and consolidation, and double the learning efficiency. For example, the principle and operation steps of oxygen production in the laboratory, hands-on experiments are much faster and more solid than rote memorization. Therefore, we should take the initiative to start the experiment under the teacher's arrangement, or carefully observe the teacher's experimental process, and strive to achieve the purpose of each experiment.

(3) Remembering is memory. Compared with mathematics and physics, "memory" is particularly important for chemistry. It is the most basic method to learn chemistry. Without "memory", talking about other things becomes empty talk. This is because: (l) Chemistry itself has a unique "language system"-chemical terms. Such as element symbols, chemical formulas, chemical equations, etc. Mastering these chemical terms is the primary task of chemistry introduction, and most of them must be memorized; (2) The nature, preparation and use of some substances must also be memorized and their laws mastered. How to remember? First of all, we should "adapt to local conditions" and find out different memory methods according to different learning contents. Concepts, laws, properties, etc. We should listen to the teacher carefully, observe the teacher's demonstration experiment carefully, and remember it on the basis of understanding; Secondly, it is necessary to mechanically remember element symbols, valence, common names of some substances and some characteristics; In addition, we should constantly look for memory methods suitable for our own characteristics to achieve the goal of "less time spent and good results".

(4) Thinking refers to diligent thinking, that is, more analysis and more thinking. We should be good at thinking from the individual to the general, from the phenomenon to the essence, and from the special to the law. In class, you should use your mouth and hands, mainly your brain, to think about "why" and "how to do it". Don't flinch when encountering difficulties, but study hard until you are suddenly enlightened; For specious problems, we should not be vague, but think deeply and get to the bottom of them. Think more, think deeply and think independently. Only "thinking" can "thinking".

(5) Practice is to ensure that you do certain exercises in and after class. It is a written form of applying what you have learned. Only through application, can you better consolidate and master your knowledge, and you can also test some shortcomings in your study, so that you can achieve better results. In addition, when we have learned most of the contents of senior high school chemistry, we will find that there are many experimental and calculation problems in chemistry, which shows that our difficulty mainly lies in the lack of basic knowledge and comprehensive problem-solving ability. In 2009, every basic concept was broken through in teachers' chemistry curriculum. Lectures 26, 27 and 28 focus on the experimental problem module, and lecture 29 teaches students the problem-solving skills of chemical calculation problems.

Students in Grade One and Grade Two still have time! It will be better to cultivate your own interests! Don't take it as a burden! It is not difficult to skillfully play with what you really like! In fact, the learning method of liberal arts is simply three words: accumulation, reading and reciting. Add math at most and do more problems.

Biology:

In retrospect, high school biology felt very relaxed when reading. I think textbooks are the most important thing. I don't remember doing a lot of exercises. I read many details of the textbook. Points are related chapters. It is also important to keep reading in class! Then do some homework properly. When you are free, look at the main points of the counseling book to help sort out and establish the knowledge structure. There is also a lot to remember when reviewing biology.

For more learning methods, it is recommended to read CVC High Score Learning Method (published by China Science and Culture Audio-visual Publishing House), which combines the learning experience of more than 400 college entrance examination champions and the essence of 16 special-grade teachers and education experts. Many cases show that the application of these methods can quickly improve students' grades, which is a set of CDs that China students can't miss and is worth recommending. The content is as follows:

1, learning quality management:

It provides methods and standards for all aspects of learning. After use, children can get the best learning quality in every link such as preview, lecture, homework, review and examination, and their memory, problem-solving ability and writing ability will be greatly improved.

2. Learning methods and examination skills of various disciplines:

For every course, every knowledge point and every question type, corresponding learning skills and solutions are put forward. For example, the stipulation method, translation method, transformation method, English ability training method, 1 second memory method and hard disk memory method in mathematics. ...

3. Analysis of key knowledge of each subject:

Clearly point out the core knowledge points, test sites, key points, difficulties, doubts and error-prone points of each subject, and give ideas for key knowledge, so that children can form an overall system of knowledge of each subject. ...
