Today, I will share with you 100 the most correct learning methods of college entrance examination summarized by top college entrance examination students. We have extracted some of the contents about high school science learning methods, hoping to point out the direction for students who still can't find the correct learning methods!
Physics high school science learning method learning method ~
Many students who have just entered high school will feel uncomfortable when studying physics, because high school physics is richer in content, more difficult and requires higher ability than junior high school, which requires students' flexibility. Many high school students find it easy to learn the motion and mechanics of objects. When they study gravity motion, mechanical problems and curve motion, they begin to be at a loss, their physics scores slide to a low point, and they gradually get tired of physics. Even when they mention physics, they will have a headache and make them unfamiliar with physics! Therefore, we should actively change the attitude and methods of learning physics and adapt to high school physics as much as possible. The following are some views and suggestions on how to learn physics well in senior high school.
1, we should lower the starting point and start from scratch.
We should change our ideas, and don't think that junior high school physics is good, but senior high school physics is good. Junior high school physics knowledge is very superficial, you can learn it with your head. In addition, through a lot of practice and repeated intensive training, your proficiency in physics will also be improved, and your physical performance will be steadily improved. It can be said that high marks do not mean good study. To learn physics well in senior high school, students need to have a strong interest in physics and good learning methods. These two conditions are indispensable. Therefore, we should change our ideas, study hard and make progress steadily!
2. Have a strong interest in 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.
3. Improve learning efficiency
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.
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.
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.
4, do a good job of review and summary.
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 it with books and notes to make its content perfect, and then make a chapter summary.
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.
5, correctly handle the exercises.
Many students pin their hopes of improving their physics scores on a large number of problems and engage in 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.
Learning methods of science in chemistry senior high school ~
Chemistry is based on experiments. Although it is attractive, many students find high school chemistry particularly difficult. Because the knowledge points of chemistry are trivial, many knowledge points still need to be remembered, so we must find the correct chemistry learning method and get innovation!
0 1
Cultivate your good observation habits and scientific observation methods.
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.
02
Active hands-on experiment
Active hands-on experiment 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.
03
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:
(1) Chemistry itself has a unique "language system"-chemical terminology. 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".
04
More analysis, 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".
05
Do more exercise.
Be sure to do some exercises in class and after class, which is a written form of applying what you have learned. Only through application can you consolidate and master knowledge better, and you can also test some shortcomings in your study and make yourself achieve better results.
abstract
The above are the learning methods of college entrance examination science summarized by the top candidates. There are also many problem-solving methods and answering skills to help those students who can't learn to find their own learning methods. I hope that students can be brave enough to climb the peak, go forward bravely in setbacks, stimulate their inner potential, realize their life value and make their life more brilliant!
