Learning experience: mathematics
Listen carefully in class and review in time after class.
The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay attention to the learning efficiency in the classroom and seek correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, we should recall the knowledge points the teacher said before doing various exercises, and correctly master the reasoning process of various formulas. If we are not clear, we should try our best to recall them instead of turning to the book immediately. In a sense, you should not create a learning way of asking questions if you don't understand. For some problems, because of their unclear thinking, it is difficult to solve them at the moment. Let yourself calm down and analyze the problems carefully and try to solve them by yourself. At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system. Do more questions appropriately and develop good problem-solving habits.
If you want to learn math well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various questions. At the beginning, we should start with the basic problems, take the exercises in the textbook as the standard, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to analyze and solve problems, and master the general rules of solving problems. For some error-prone topics, you can prepare a set of wrong questions, write your own problem-solving ideas and correct problem-solving processes, and compare them to find out your own mistakes so as to correct them in time. We should develop good problem-solving habits at ordinary times. Let your energy be highly concentrated, make your brain excited, think quickly, enter the best state, and use it freely in the exam. Practice has proved that at the critical moment, your problem-solving habit is no different from your usual practice. If you are careless and careless when solving problems, it is often exposed in the big exam, so it is very important to develop good problem-solving habits at ordinary times. Adjust the mentality and treat the exam correctly.
physics
First of all, we should focus on basic knowledge, basic skills and basic methods, because most of the exams are basic topics. For those difficult and comprehensive topics, we should seriously think about them, try our best to sort them out, and then summarize them after finishing the questions. Adjust your mentality, let yourself calm down at any time, think in an orderly way, and overcome impetuous emotions. In particular, we should have confidence in ourselves and always encourage ourselves. No one can beat me except yourself. If you don't beat yourself, no one can beat my pride.
Be prepared before the exam, practice routine questions, spread your own ideas, and avoid improving the speed of solving problems on the premise of ensuring the correct rate before the exam. For some easy basic questions, you should have a 12 grasp and get full marks; For some difficult questions, you should also try to score, learn to score hard in the exam, and make your level normal or even extraordinary. First, to learn physics well, we must first pay attention to the understanding and memory of basic knowledge.
Basic knowledge includes three aspects: basic concepts (definitions), basic laws (laws) and basic methods.
2. What is real understanding?
To learn physics, we should know the exact meaning and truth of what we have learned. To what extent can we really understand? The standard of understanding is that you can answer questions such as "what", "how" and "why" for every concept and law. For some similar and confusing knowledge, we should be able to tell their connections and essential differences; We can use the concepts and laws we have learned to analyze and solve some specific physical problems.
3. Recite some concepts, formulas and inferences.
Second, pay attention to classroom learning.
1, preview before class can ensure that you listen carefully in class.
2. Classroom is an important position to acquire knowledge.
Step 3 take notes carefully
Third, pay attention to the application and consolidation of what you have learned.
We should be good at applying what we have learned in physics to practice. If you don't pay attention to the application of knowledge, your knowledge is still dead and incomplete. Only through concrete application can we expand and deepen our understanding of knowledge, learn to analyze specific problems and improve our ability to analyze and solve problems.
1, insist on doing the problem independently
Yan Jici, a physicist in China, once said: "Doing problems can deepen understanding, achieve mastery through a comprehensive study, and exercise the ability of thinking and solving problems. If you can't do an exercise, you don't really understand it; Even if you do all the exercises, it doesn't necessarily mean that you understand them, because sometimes you are just trying to calculate the formula. If you know where you know and where you don't know, you can still try to understand. You can do less exercise at this time. " It can be seen that learning physics must be independent (meaning independent of others) and do some problems with good quality and quantity. There must be a certain number of topics, not too few, but more. In other words, it must be very difficult. No one can learn math and physics well but this hurdle. Solving problems independently may sometimes be slow, sometimes detours, and sometimes even impossible, but these are normal, and this is the only way for any beginner to succeed.
2. Learn to analyze physical processes.
When studying physics, we should pay attention to the study of physical process and make it clear. If the physical process is unclear, there will be hidden dangers in solving problems. No matter how difficult the topic is, we should try our best to draw pictures, some can draw sketches, some can draw accurate pictures, and we should use compasses, triangles, protractors and so on. To represent geometric relationships. Drawing can turn abstract thinking into image thinking and grasp the physical process more accurately. With pictures, we can make state analysis and dynamic analysis.
3. Master scientific thinking methods.
The methods of physical thinking include analysis, synthesis, comparison, abstraction, generalization, induction and deduction. In the process of physics learning, abstraction and generalization are the main ways to form physical concepts, and deduction, induction and generalization are the main ways to establish physical laws, while the methods of analysis, synthesis and comparison permeate the whole physical thinking, especially when solving physical problems.
4. Consolidate what you have learned in time.
We should review and consolidate what we have learned in time. We must review the whole process of introduction, analysis, generalization, summary and application of the new knowledge we have just learned in class after class, and compare it with similar old knowledge in our brains to see if there is any contradiction, otherwise it means that we have not really understood it. At this time, it is necessary to rethink and reread. On the basis of understanding what you have learned, you must finish your homework in time, and students who have spare capacity can do it appropriately.
Fourth, pay attention to the collection and arrangement of learning materials and the accumulation of knowledge.
1. Read the appropriate extracurricular books.
2. Organize your study materials.
3. Pay attention to the accumulation of knowledge
chemistry
First, read the chemistry textbook carefully.
Chemistry textbook is a teaching book that systematically expounds the contents of the textbook according to the syllabus. Grasping textbooks will also grasp basic knowledge. We should focus on the main principles, laws and important conclusions and laws in textbooks and remember them. At the same time, we should also pay attention to the methods of studying problems in chemistry. Mastering scientific learning methods is more important than mastering knowledge. Because it can improve the thinking ability of learning.
The process of reading chemistry books is generally divided into three steps.
1. Read a textbook comprehensively, grasp the overall content of a book, form a preliminary overall impression in your mind, and outline the key, difficult, key and essential issues in the textbook.
2. Grasp the key. On the basis of comprehensive reading, focus on the key points, difficulties and key terms in the textbook, and ponder carefully.
3. Think positively when reading, master key knowledge and gradually break through difficult knowledge.
Second, pay attention to the learning methods of chemistry.
Learning method is the way and strategy for students to acquire knowledge, master knowledge, develop intelligence and cultivate ability.
Third, grasp the law, learn to associate and simplify memory.
Chemistry, compared with mathematics and physics, places more emphasis on memorizing things, is more "abnormal" knowledge, and its regularity is not very strong. How to systematize seemingly messy knowledge and simplify memory is a problem that must be solved to learn chemistry well.
