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. Developing good habits and standardizing exercises is an important part of high school learning, which 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, we are required to remember a lot of knowledge 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. 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. 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 develop abilities. 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 science and technology 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.
