How do middle school physics teachers improve themselves?

Q: A: There is a saying that teaching middle schools with a bachelor's degree is not a problem in terms of physical content, but only improves educational theory. But according to my experience and contact with teachers, what middle school physics teachers need to improve is mainly in physical cultivation. This is not to say that the content of physics is wrong, but that the understanding of scientific content is sometimes superficial, it is difficult to do a good job in teaching, and it is often just scripted. In the teaching career, we should constantly study physics, not only by reading some popular science books, but also by studying real physics, which should be quantitative and calculated. It is also of great significance to experience, relive and enjoy the learning process constantly, and keep fresh and excited about the unknown. With this experience, students' feelings, attitudes and values can be influenced by this. Just as important as educational theory, if not more important, is the thinking of philosophy of science. What is the essence of science, what is the scientific method, and what is the relationship between science and people … Now many teachers have been thinking about this question. For example, Wu Jiashu's philosophical thinking on physics teaching and Pei Jun's new high school curriculum from a cultural perspective are all worth reading carefully. In addition, a set of books about richard feynman published by Hunan Science and Technology Publishing House is also very good, such as Introduction to Feynman Physics, Feynman's Relativity of Physics, Essence of Physical Laws, Joy of Discovery, etc. And Physics and Art, edited by Shi Daning and published by Science Press, should be read by middle school physics teachers. Personally, I feel that these books have a considerable influence on the guiding ideology when compiling physics textbooks for high schools in the new curriculum. What needs to be emphasized again is that we should seriously study real physics and quantitatively think about some physical problems outside teaching, otherwise the thinking of philosophy of science will be shelved and become a rootless source.
