First, the characteristics of high school learning
1, characteristics of high school textbooks
(1) The amount of knowledge has increased. High school is similar to junior high school, but the amount of knowledge in high school is larger than that in junior high school. For example, there are about 60 physical mechanics knowledge points in junior high school and 90 mechanical knowledge points in senior high school.
(2) theoretical enhancement, which is the most important feature. Some junior high school textbooks only require preliminary understanding and qualitative research, while senior high school textbooks require in-depth understanding and quantitative research, which greatly strengthens the abstraction and generality of textbooks. For example, junior high school algebra focuses on solving equations and operations, while senior high school algebra is an abstract set and mapping from the beginning. Politics in junior high school is about law, which is related to facts. High school requires learning philosophical things such as economics and Marx's theory, which is relatively abstract.
(3) Systematically strengthening high school textbooks often take some basic theories as the key link and link basic concepts, basic principles and basic methods according to certain logic. Form a complete knowledge system. The correlation of knowledge before and after is one of its manifestations. In addition, the formation of knowledge structure is another manifestation, so the knowledge structure of high school textbooks is obviously upgraded.
(4) Comprehensively enhance the mutual penetration and mutual application of knowledge between disciplines, and deepen the learning difficulty. For example, analyzing and calculating physical problems requires knowledge and skills such as mathematical functions and solving equations.
(5) Ability improvement requires further improvement and training of reading ability, writing ability, calculating ability and experimental ability.
2. High school students' intellectual development requirements
It is generally believed that intelligence includes observation, memory, thinking ability and imagination, which requires senior high school students to develop intelligence accordingly.
(1) When observing things, we should be more purposeful, comprehensive and profound, and be able to distinguish between major and minor, inevitable and accidental phenomena; Not only static observation, but also dynamic observation; Not only qualitative research, but also quantitative analysis.
(2) Require memory to be based on logical recitation, and strive to grasp the internal relations of teaching materials on the basis of understanding and carry out memory.
(3) Use concepts, judgments and reasoning for logical thinking. At the same time, we should think independently and study problems.
(4) Imagination should be greatly developed. To concretize and visualize abstract problems, for example, from plane geometry to high school solid geometry, it is necessary to develop spatial imagination.
Second, high school learning methods
Einstein has a formula for success: a = x+y+z. A stands for success, X stands for hard work, Y stands for correct method, and Z stands for less nonsense. This formula points out three elements of career success. For learning, success also has three elements: learning success = psychological quality, learning methods and intelligent quality.
1, improve the psychological quality of learning
(1) learning motivation. Learning needs motivation. It is very important that students' learning motivation is due to their personal needs. Some people have a strong thirst for knowledge and a strong interest in learning, which is exactly the case, such as further education, employment, interests, hobbies, honor, status, thirst for knowledge, career and future. Efforts should be made to strengthen the motivation of learning, such as setting up lofty ideals; Participate in various competitions, challenge the strong and stimulate the desire to learn; Encourage yourself when you see your academic achievements, so as to enhance your self-confidence, suffer setbacks and have the spirit of being unwilling to fail and humiliate.
(2) interest in learning. Strong interest in learning is closely related to efficiency, which can stimulate interest in learning from curiosity and thirst for knowledge. Such as physical experiments and chemical changes. It is easy to arouse people's curiosity and thirst for knowledge; Cultivate interest in all subjects. It is often after hard study that we discover the mystery and use of knowledge and improve our academic performance, so we must enter the "sea of books"; When applying knowledge to practice, stimulating interest and solving problems with what you have learned, that sense of success can easily stimulate interest in learning.
(3) Learning emotion, will and attitude. Linking positive emotions with learning to prevent the breeding of negative emotions can promote learning. Being good at controlling yourself is the key to learning willpower. It is particularly important to control and restrain your own behavior, control unnecessary thoughts and emotions, and concentrate on your studies.
2. Master scientific learning methods.
(1) preview the whole content of the textbook carefully before reading, give full play to your self-study ability, sort out what you already know and what you have doubts or don't understand (that is, find the key points and difficulties), mark it well and write it down separately. This not only improves the ability of self-study, but also paves the way for attending classes, forming a psychological set that expects teachers to analyze; This set of psychological needs will definitely stimulate our enthusiasm for learning and highly concentrated attention.
(2) Listening to lectures is the best shortcut to acquire knowledge, and the teacher teaches the truth that has been verified by history; It is the essence of teachers' long-term study and teaching practice. Because it is particularly important to improve classroom efficiency, how to improve classroom efficiency? A, prepare well before class. Mental preparation is very important. Keeping energetic and clear-headed in class is the premise of learning knowledge well.
B, concentrate. When you are distracted, you are distracted. Everything depends on reason to force yourself to concentrate on listening, and to eliminate interference by will. C, careful observation, positive thinking. Don't be a passive receiver of information, fully mobilize your enthusiasm, follow the teacher's teaching ideas, and actively think about the teacher's explanation. Conclusion It is better to learn from students' own observation, analysis and reasoning than to listen to ready-made conclusions first.
D, fully understand and master the method.
E, grasp the key points of the teacher's lecture. Some students often ignore the beginning and end of the teacher's lecture, which is wrong. The beginning is often a few sentences, but it is the outline of the whole lecture. As long as you grasp this outline and go to class, the following content will be clear. Although there are not many words at the end, it is a refinement and review reminder of the essence of a lesson. At the same time, pay attention to the parts repeatedly emphasized by the teacher.
F, do a good job in class notes. Memorizing by taking notes is one of the best ways to strengthen memory. Notes, an eternal record, can overcome the limitations of brain memory. As the saying goes, a good memory is not as good as a bad writing, so in order to fully understand and digest, you must take notes. At the same time, taking notes and fully mobilizing the organs such as ears, eyes, hands and heart to work together are helpful for learning.
G, pay attention to the communication with the teacher, eye contact, question communication, can promote learning.
(3) The method of homework is to improve thinking ability, review and master knowledge, and improve the speed of solving problems. By examining questions, analyzing problems and solving problems, we can consolidate and test ourselves. Of course, when analyzing problems, there are several ideas, such as forward deduction, reverse deduction, two-way deduction, auxiliary deduction and so on. In addition, homework must not be copied, which is meaningless. If you don't understand, you must understand it in time.
(4) Review method: German educator Stilwell said: "We must always go back to what we have learned to review ... It is much better to firmly remember what we have learned than to learn something new and forget it soon." Therefore, the "cramming" before the exam is often not feasible. Review lies in peacetime, how to review?
A, after-school memory, that is, on the basis of listening to lectures, recall what you have learned.
B. intensive reading of textbooks. The more thoroughly you understand the textbook, the more firmly you master it, and the efficiency will naturally improve.
C. organize your notes.
D, read reference books. This is a good way to supplement extracurricular knowledge.
E, fill in the blanks and master the knowledge structure systematically.
F, periodic review. Review A, review B, review A after review B, and then move on ... This kind of cyclic review is good for memory.
Generally speaking, the scientific learning method can be summarized by the following ballad: preview before class and listen to the class easily. Review the old and learn the new, and the ambiguity can be seen. Learn new content by yourself and focus on learning. Make a list of questions and have a goal in class. Pay attention to the class and try to eliminate interference. Take simple notes and think more. After class, you must review and recall the first rule. Read, digest and chew carefully. Pay attention to doing your homework, don't copy it. Weaving knowledge network is concise and clear.
3. Develop intelligence and improve ability.
(1) Cultivate observation. Observation is an important link in mastering knowledge and learning well, and it is also a necessary condition for success. Smart, that is, hearing is good, eyesight is good, observation ability is strong, scientific observation methods are mastered, a, the purpose is clear, the plan is careful, and various observation methods are flexibly used, such as repeated observation, comparative observation, regular observation, combined with thinking observation, etc.
(2) improve memory ability. The root of all wisdom lies in memory. The principle of memory changes with time, and the speed of forgetting is very fast within a few days after learning. But after a week, the speed of forgetting slowed down. Therefore, the key to memory is to consolidate review in the most easily forgotten days. Choose the best period of memory, because everyone's situation is different, and you can't draw an absolute conclusion. But mastering time arrangement is the eternal truth to improve memory ability. In order to fight against forgetting, the correct arrangement of review time is to choose the best study period.
First, review in time. Bring back the materials that have been memorized for consolidation. Its physiological basis is to strengthen temporary nerve connection and further consolidate traces. Because forgetting is fast first and then slow, so review must be timely, before forgetting has started on a large scale.
B, reasonably arrange the time and quantity of review. Experiments show that learning the same content for a relatively concentrated period of time has a good memory effect. But it should also be dispersed appropriately, because the review time is too concentrated and easily disturbed; Too scattered and easy to forget.
C, alternately allocating time to study can also improve memory. Scientific experiments have proved that it is fast to stimulate brain nerve cells with electric pulses of equal frequency, but once the stimulation time is too long, the response of nerve cells disappears. After a period of rest, the reaction recovered. The same is true of human memory. Madame Curie, a French scientist, once said, "I read several books at the same time, because studying only one thing will make my precious mind tired." Therefore, we must "alternate distribution" to remember.
D, it is also effective to use various memory methods. Such as characteristic memory; Song must remember; Image memory; Comparative memory; Associative memory and so on.
(3) Develop thinking ability.
A, learn basic knowledge and practice basic skills;
B, improve language expression ability;
C, master the basic thinking methods;
D, improve their thinking quality (continuous learning);
E, develop good thinking habits.
(4) Develop imagination.
A, learn rich knowledge and experience;
B, learn poetry and painting;
C, develop ideas and research hypotheses;
D, learn how to stand and use space imagination;
E, participate in creative activities.
(5) Cultivate self-study ability and acquire knowledge by yourself with your own mind.
At the same time, creativity should be brought into play in the cultivation of learning methods. This is the requirement of the times and the future. Developing creative thinking and encouraging diversity and individuality are conducive to the development of innovation, technology and learning.
In short, optimizing psychological quality is the confidence and courage to overcome difficulties in high school study; Mastering scientific learning methods means operating correct strategy and technology; Improving intelligence means improving weapons for tackling key problems, and both are indispensable.
If we compare our study to sailing, diligence is the engine of the ship; The correct learning method is the steering wheel and course of the ship. Let's sail on this ship of hope and swim in the ocean of knowledge. Let the boat take us to a better place!
I think a good exercise book is very important, and whether it can be done is also very important. Let me talk about my study method.
Mathematics, the remedial class we study and distribute, is a good exercise book. These questions are very difficult. There is a summary of knowledge points in front. Every time you do it, you should first summarize the knowledge points and then look at the examples. This workbook is an example corresponding to the class problem. After reading the examples, you should do the class questions. After learning this part, you should do the tutorial after class. Even if you spend more time on the wrong question, you should go back and think about what is wrong and the correct answer. Do you understand if you look for it? Less than this book, you can choose the middle point of the book, which is also very good. If you sum up the knowledge well, you should do the examples first, and then do the exercises. If you don't understand, ask the teacher to prepare a blank math book immediately, because after school starts, the teacher usually copies some questions on the blackboard. These questions should be done very carefully, because they will be used when you review yourself! Besides, this is the essence of teachers' knowledge. He chose more than a dozen exercises, which must be very representative. The teacher will talk about his methods and ask the students about them. After writing the questions, leave a certain place to write down the good methods, but his own methods should be improved, because it is generally not easy to master other people's methods, and he will be impressed.
There is a big difference between high school Chinese and junior high school Chinese. Generally speaking, basic knowledge is very important. There is a pronunciation question, a glyph, a sick sentence, a notional word and a function word, three scientific words and three classical Chinese in the college entrance examination. You don't have to do special questions, just talk to the teacher. The teacher will tell you a lot of things, write them down in a notebook, buy a book with chapters, and post how many notes you have divided at will, and which part is very useful for learning Chinese.
It is also important to take notes in English. Can't do miscellaneous notes. Even if the teacher said it, it was useful and useless. General verb phrases are useful. It is important to remember these phrases. You can buy Wang Houxiong's textbook and solve it completely. There is no need to do other questions. Look at the tutorial on the left first, and then do the corresponding questions. Only do multiple-choice questions because multiple-choice questions help you the most, and choosing the best others will be better.
Chemical equations are very important. High school chemistry knowledge should be placed beside the teacher. Chemistry is semi-illiterate and semi-logical, and you can also choose Wang Houxiong's textbook to fully understand it.
Physics: I feel that there is a book called Two-speed Learning Method, which is very good. You can buy it and have a look.
Never buy exercise books for miscellaneous subjects, just don't ask the teacher right away. Don't think so: wait until you finish the exam or have time to study, because high school knowledge waits for no one, and you can study math and physics by yourself during the holidays, and you can study for a mid-term exam of about 10 days at most. In the process of self-study, you can cooperate with the workbook. The most important thing in the process of self-study is to find the place where you can learn. Not yet, after the teacher said he wouldn't know. In fact, the biggest advantage of self-study is not to let you learn the course once, but to let you know the high school textbooks and high school learning methods, and find the most suitable method in the process of self-study.
Don't stay up too late. Go to bed at 10, study in a planned way, make a calendar, write down what you want to do every day and tick it.
Before class, you'd better preview what will be taught in the textbook. This time, it is clean. I knew what to say. Write down what you don't understand and listen carefully in class. Preview is to make the class know fairly well and improve the efficiency of the class.
The first thing after class is not doing exercises, but reading the text. After-class review is a stage of digestion and a positive thinking process of in-depth understanding, analysis and synthesis. Be sure to read the textbook in a timely, serious and word-for-word manner, and on this basis, actively digest it with your brain and hands.
Finally, every time you finish learning a chapter, you should read the whole chapter again, make a summary of the whole chapter, organize the whole chapter into systematic content purposefully, and master it systematically. This is a kind of knowledge induction.
(2) extensive extracurricular reading
In addition to intensive reading of textbooks, extensive extracurricular reading, especially popular science books and newspapers, should be carried out to broaden our horizons and cultivate self-study ability. For articles in popular science newspapers and periodicals, you can read them intensively except those you are particularly interested in, and generally read them extensively. In extensive reading, you may encounter some problems that you don't understand or understand very well. It doesn't matter. It is also beneficial to know that there is such a thing from reading. The main significance of this kind of reading is to expand knowledge and activate thinking.
Step 3 do the experiment carefully
Experiment is the foundation and the most important research method in physics, chemistry and biology. When studying physics, chemistry, biology and other subjects, experiments can help us understand and consolidate relevant knowledge. Therefore, we must learn to experiment. High school, how can we do scientific experiments?
(1) We should study well the famous experiments in history. Learning the experimental methods, experimental principles and experimental devices of these famous experiments in history can inspire our own ideas, let us learn from them in our own experiments, and realize the importance of careful observation and scientific induction of phenomena.
(2) Observe the demonstration experiment correctly. Classroom demonstration experiment is an experiment that teachers operate, guide us to observe correctly, and analyze and summarize the rules from the experiment. At this time, although we didn't have a chance to start work, we could fully watch, listen and think during the experiment. Observe and demonstrate the experiment. First of all, we should listen carefully to the teacher explain why we should do this experiment, how to arrange it, make clear the purpose of the experiment, know what factors to consider, what interference to eliminate, what instruments to use, what their functions are, and so on. In the process of demonstration, we should see clearly the purpose of each step, the operation process, the process of phenomenon change, how to succeed, how to lead to failure and so on. In short, when watching the demonstration experiment, we should observe and think carefully, pay attention to the purpose, principle, device, experimental operation steps and changing process of the experiment, instead of just looking at the experimental results, let alone being satisfied with just looking good and fun.
(3) Do the experiment carefully. Students' experiments arranged in teaching are extremely valuable learning opportunities. It is better to look than to do. To truly master the experimental skills, we must pass our own practice. How to do experiments well? Then we must do "six wants and six don't":
First of all, we should preview, make clear the purpose, principle and steps of the experiment, and be aware of it. Don't be confused, you are in a hurry during the experiment, and you are at a loss about the experimental results after the experiment.
Second, we should know the performance and precautions of the instrument and take good care of it. Don't fiddle with it, just use it.
Third, we should carefully observe the details of the experimental phenomenon and the changing process, and see the essence through the phenomenon. Don't watch the fun casually.
Fourthly, it is necessary to operate normally and cultivate good experimental literacy, which is the guarantee for obtaining accurate experimental results and success. Do not operate or even damage the instrument at will.
Fifth, we should not only work hard on the operation, but also actively think deeply about why we should do this, instead of doing it without thinking.
Sixth, we should carefully process the experimental data, analyze the experimental results, find out the causes of errors, and fill in the experimental report. Don't be careless. Only by piecing together the data can you get satisfactory results.
4. Develop good exercise habits and norms.
Doing problems is an important part of high school learning and has always been valued by students. It plays a great role in thoroughly understanding and consolidating the knowledge learned and cultivating the ability to apply knowledge to solve practical problems. To practice well, you must have good habits. If we only pursue the answers and quantity of solving problems, we will get caught in the ocean of problems and will inevitably achieve little results.
Understanding and mastering the basic knowledge is the premise of completing the exercise correctly. Basic concepts and laws are the basis of solving problems. It is often because you don't have a good understanding of basic concepts and laws that you can't solve problems or make mistakes in solving them.
What are the correct methods and good habits of doing exercises?
First of all, we should review the topic carefully. For example, to solve physical problems, we must first carefully analyze the research object and physical process. Read every sentence, every concept, every number and every unit in the topic carefully to make yourself clear about the meaning of the topic. Then determine which object or system the research object is and what process these objects go through, so as to determine the goal and basis for solving the problem.
Sketch is a method to help us analyze the theme and make it visual and concrete.
We should list the known conditions and unknown quantities one by one. Some of the known conditions in the exercise questions are directly given known numbers, and some are not directly given, but indirectly given, implied in some given values or information. Only through analysis, according to some interrelationships, can we find them out.
According to the analysis of the meaning of the question, find out the changing relationship between physical quantities and determine the physical formula for solving the problem. In some exercises, we should pay special attention to the approximate condition or critical state of the turning point. We should also pay attention to many physical exercises. Because of different thinking angles and ideas, different research objects and different physical formulas and mathematical methods, there are several different solutions. When you do a problem, you should practice multiple solutions to one problem. Through the analysis and comparison of various schemes, we can not only master knowledge, but also learn to choose the simplest and most ingenious scheme.
In operation, the unit system must be unified.
When solving physics exercises, you can't think that you have achieved your goal as soon as you work out the results. You should also study whether these results are reasonable and complete, whether there is a range of values, and so on. It is necessary to confirm that the answer is comprehensive, reasonable and correct in order to solve the problem.
Pay attention to cultivate a serious and rigorous style of study when doing the questions, so as to achieve standardized expression.
After the exercises and questions are corrected and sent back by the teacher, we should not only look at the scores, but also seriously study the problems pointed out in the teacher's correction, check and find our own loopholes and mistakes in knowledge understanding and application, and make up and correct them in time. It is necessary to establish a record of wrong questions, carefully analyze the reasons, find out the corresponding weak knowledge points and strengthen them to avoid repeating the same mistakes.
5. How to master memory
In learning, there is a lot of knowledge that we are required to learn by rote so that we can use it at any time. How can we remember them quickly, completely and accurately?
Understanding is the basis of memory. In senior high school, we should emphasize memory on the basis of deepening understanding, and have higher requirements for the combination of understanding and memory.
Some concepts and laws of science seem simple, while others are abstract and complex. In any case, we should analyze it when studying, find out the ins and outs, highlight the elements and grasp the key points, so as to deepen the impression, remember while understanding, and use it flexibly when analyzing and solving problems. (highlighting the key memory method)
When studying some problems, many concepts and laws often appear in groups. In learning, we should not only find out their ins and outs, but also compare them vertically and horizontally to find out how they were obtained and applied, how to deduce other formulas from some formulas, and compare them with related similar formulas in form, content and characteristics. You can do list analogy and knowledge classification to master the internal relations and differences of knowledge. In this way, for more complex content, we can sort out the system and clues, and remember and use them clearly. (Contrast contact classification memory method)
Repeated self-inspection and repeated application are necessary steps to consolidate memory. After each class, review, unit review, problem-solving application, experimental operation and semester review should be planned and arranged in order to continuously consolidate their memories.
4. Combine learning knowledge with learning methods to cultivate ability.
In learning, we should not only master the basic knowledge of various subjects, but also combine some scientific research methods to cultivate the ability to study, work and explore the unknown effectively. With these abilities, you can learn quickly and well, and when you grow up, you will have stronger ability to work independently and to invent and create.
When solving problems, we should not just forget, but rise to the height of mastering the basic methods of solving problems.
In high school, there are many abilities to be cultivated. The following mainly talks about observation ability, thinking ability, practical ability, and the cultivation of innovative spirit and creativity.
Observation ability A student with strong observation ability can grasp the characteristics of processes and phenomena, keenly discover some unexpected or subtle phenomena, and gain a lot of knowledge from his daily life. How to cultivate your observation ability?
When observing, we should have a clear purpose and concentrate on it, and grasp the characteristics of the observed phenomenon. For each step of the experiment, we should be clear about what we are mainly exploring or verifying, and focus on this point. We must also observe carefully and pay attention to what new phenomena appear, instead of passing by and turning a blind eye.
We should also have keen observation and observe some phenomena repeatedly. Thinking actively in the process of observation can continuously improve your observation ability in practice.
Thinking ability Thinking ability is the core of all kinds of abilities. Thinking includes analysis, synthesis, generalization, abstraction, reasoning, imagination and other processes. It is necessary to cultivate thinking ability through the formation of concepts, the conclusion of laws, the establishment of models and the application of knowledge. Therefore, in the process of learning, we should not only learn knowledge, but also learn scientific thinking methods and develop thinking ability.
In order to improve our thinking ability, we should always study by comparative methods. First of all, when learning every new concept, we should not only listen to the teacher's explanation, but also compare ourselves, find out similar examples and deepen our understanding. Second, compare concepts and laws with similar meanings, and analyze their differences and connections from many angles and aspects. If you often study by comparative methods, you can learn to analyze problems comprehensively and find their connections, differences and respective characteristics from various things, thus improving the breadth and depth of thinking.
In the study of practical ability, we should be good at both thinking and hands-on. Practical operation ability mainly refers to being able to make things and develop a series of will qualities related to intelligence (such as designing operation steps in advance, correctly using instruments and tools, paying attention to accuracy and precision, correcting deviations as soon as possible or quickly changing to a more reasonable scheme, etc.). ). Doing well in group experiments and small experiments in class and actively participating in various creative experimental design and scientific and technological inventions after class can improve your practical ability. In classroom, extracurricular experiments and various design and production activities, we should strive to combine with the application of modern information technology to cultivate the ability of collecting, processing and utilizing information.
Innovative spirit and creative ability To cultivate one's creative ability, one must first learn to find problems and dare to ask them. Einstein said, "Finding problems is often more important than solving them." We should dare to question the existing conclusions, express our different opinions and "discover" knowledge through our own exploration. We should learn to learn how to learn, how to think, how to seek differences and how to innovate through research study under the guidance of teachers in class, as well as self-determined topics and independent research exploration after class. You know, the development of science is inseparable from creation, and if you want to achieve something in science in the future, you can't do without creative thinking. Today, with the spirit of innovative learning, we can seize the "commanding heights" in the field of advanced scientific and technological development in China's socialist construction, and then control a large open area and become outstanding talents to climb the peak of science and technology.
