Xi methods for senior three physics: how to learn physics well.
First, first of all, we must change the concept that physics is good in junior high school, but physics in high school is not necessarily good.
The knowledge of physics in junior high school is relatively simple, and the content is not much, which is easier to grasp. In addition, in the late third year of junior high school, through a large number of Xi practice, through repeated intensive training, the proficiency level is improved, and the physics score can be greatly improved. But a high score does not mean that you are good at physics and can learn physics. If the interest in learning Xi physics is not cultivated, and there is no good way to learn Xi, it is difficult to learn high school physics well. Therefore, first of all, we should change the concept that if you are good at physics in junior high school, you will not necessarily learn physics well in high school. So lower the starting point and start from the beginning.
2. A strong interest in Xi physics should be cultivated.
Interest is one of the driving forces of thinking, interest is a strong and lasting motivation to learn Xi, and interest is the potential motivation to learn physics well. There are many ways to develop interest, and from the student's point of view, it should be noted that physics is closely related to daily life, production, and modern technology. There are many physical phenomena around us, and a lot of physical knowledge is used, such as: when speaking, the vocal cords vibrate to form sound waves in the air, and the sound waves are transmitted to the ears, causing the eardrum to vibrate and produce hearing; When drinking boiling water, drinking beverages, and when the pen absorbs ink, atmospheric pressure helps; When walking, the static friction between the feet and the ground helps, and the walking process is formed by a continuous pouring action; When washing rice, the debris in the rice is removed, and the buoyancy knowledge is used; When your child goes swimming, he strokes his hand to the side of his thigh, moves his leg forward, and so on. There are also one of the four great inventions in ancient China, the compass, the invention of the geodynamic instrument, ancient Chinese medicine and steelmaking that began in the Warring States Period, the emergence of the smelting and casting industry in the Northern and Southern Dynasties, as well as the production and marketing of cotton, and early water conservancy projects, etc., to understand the history of the development of ancient physics and industrial and agricultural production in China, which can stimulate students' patriotic enthusiasm and enthusiasm for learning Xi, and improve the enthusiasm of learning Xi.
3. In the classroom, improving the efficiency of listening to lectures is the key.
During Xi, time in class is important. Therefore, the efficiency of listening to lectures determines the basic situation of learning Xi, and the following aspects should be paid attention to to improve the efficiency of lectures:
Pre-class Xi can improve the pertinence of the lecture.
The difficulties found in the pre-Xi are the focus of the lecture; For the old knowledge encountered in the Xi, the relevant knowledge that has not been mastered well can be filled in and the new knowledge can be understood, so as to reduce the blindness and passivity in the process of listening to the class, and help improve the efficiency of the class. After the pre-Xi, you can compare and analyze the knowledge you understand with the teacher's explanation, so as to improve your thinking level, and you can also cultivate your self-learning ability Xi pre-.
During the lecture, you should concentrate and pay full attention, and you should not desert.
Concentration means to devote oneself to the Xi in the classroom, so that the ears can reach it, the eyes will reach it, the heart will reach it, the mouth will reach it, and the hands will reach it. If you can achieve these "five tos", your energy will be highly concentrated, and all the important content you have learned in class will leave a deep impression on your mind. It is necessary to ensure that you can pay full attention during the lecture and do not desert. Before class, you must pay attention to the ten-minute break between classes, and should not do too intense sports or heated arguments or watch ** or do homework, etc., so as not to be out of breath after class, think about what is wrong, and cannot calm down, and even the brain begins to sleep. Therefore, you should make good material and spiritual preparations before class.
