Physics in the second year of junior high school is the initial stage for students to get in touch with physics, and this stage of learning is very important for subsequent physics learning.
However, many Grade 8 students feel a lot of pressure about the new physics subjects, finding physics difficult, boring, and abstract, and always at a loss when doing problems. There are four main reasons for this phenomenon:
1. Improper learning methods: Many second-year junior high school students have misunderstandings about the way they learn physics, thinking that they only need to memorize formulas and concepts, but this method cannot truly understand and master physics knowledge.
2. Fear of difficulties: Due to the abstract and difficult understanding of physics, many second-year junior high school students are afraid of difficulties and are unwilling to spend time and energy to study physics.
3. Improper learning methods: Although some second-year students study physics very hard, their grades are not satisfactory. This is often caused by improper learning methods.
So, how to overcome these problems and learn junior high school physics well?
1. Master the basic physical methods
1. Experimental methods. Experimental methods are important methods for discovering and verifying physical phenomena or laws. It is necessary to be good at using experimental equipment or daily necessities to carry out simple experimental operations, observe experimental phenomena, record experimental data, and analyze experimental results.
2. Reasoning methods. Reasoning methods are important methods for deriving and proving physical formulas or laws. Be good at using tools such as logic or mathematics to reason rigorously, and pay attention to testing the correctness and rationality of reasoning.
3. How to solve the problem. Problem solving methods are an important way to apply and consolidate physics knowledge. It is necessary to be good at using various methods such as analysis, synthesis, analogy, and commutation to solve problems, and pay attention to the norms and skills of problem solving.
2. Cultivate good physics habits
Physics is a science that requires long-term persistence and accumulation, and in order to learn physics well, it is necessary to cultivate good physics habits and be able to persevere. Good physical habits include the following:
1. Preview habits. Preview is the first and very important step in learning. Through the preview, you can understand the main content and requirements of the course in advance, and lay a foundation for listening to the class.
When previewing, you should pay attention to reading the textbook, understand the theme, objectives, key points and difficulties of each lesson, mark out key words, concepts, formulas, etc., try to explain or summarize in your own words, put forward your own questions or feelings about the course content, and record them in your notebook in order to seek answers or exchange ideas in class.
2. Lecture habits. Listening to lectures is the core part of learning, and it is also the most effective part. Through listening to the lectures, you can obtain professional guidance and explanations from teachers, and deepen your understanding and mastery of knowledge points.
When listening to the class, you should pay attention to concentration, maintain a high degree of attention and interest, actively participate in the interaction, record the important information and new knowledge explained by the teacher, do not have to copy the existing content in the textbook or board book, you can use mind maps, graphics, symbols and other tools to sort out and simplify your notes to make it more organized.
3. Review habits. Review is the consolidation stage of learning, but also the improvement stage. Through review, you can digest and absorb the knowledge you have learned, check and fill in the gaps, and improve your level.
(1) When reviewing, you should pay attention to regular review to avoid forgetting. Review what you learned that day, review what you learned that week, and review what you learned that month every month.
(2) Summarize and systematize knowledge. Use mind maps, framework diagrams and other methods to summarize the knowledge points of each unit or chapter, and establish your own knowledge structure.
(3) Do practice questions to test your level. Choose the appropriate difficulty and type of questions according to your weak points to practice, analyze the causes of mistakes and how to improve.
4. Expand habits. Expansion is the deepening stage of learning, but also the stage of innovation. Through expansion, you can expand your knowledge and horizons, and improve your interests and abilities.
3. Adjust the physical mentality
Physics mindset is an important factor in learning physics, and it is also an important factor that affects physics performance. To learn physics well, you must adjust your physics mentality and get rid of some negative emotions and thoughts. There are several ways to adjust your physical mindset:
1. Build self-confidence and overcome fear. Don't be afraid or give up because physics is difficult, believe that you have the ability to learn physics well, have the courage to face and overcome difficulties, and actively seek help and guidance.
Stay optimistic and enjoy learning. Don't be bored or lazy because physics is boring, find fun and meaning in physics, take learning physics as a challenge and achievement, and enjoy the process and results of learning.
3. Cultivate interest and stimulate motivation. Don't ignore or perfunctory because physics is useless, discover your interests and directions from physics, take learning physics as a kind of exploration and innovation, and stimulate your own learning motivation and goals.
