Physics in senior high school is difficult to learn, and the difficulty lies in the "step" in the connection between junior high school and senior high school. This step lies in the contents of physics textbooks, teaching methods and students' learning ability, thinking methods and psychological characteristics. Most of the physical phenomena and processes in junior high school physics learning are "tangible" and often closely related to daily life phenomena. Students' thinking activities in the learning process are mostly vivid and concrete thinking based on vivid natural phenomena and intuitive experiments, and it is less required to apply scientific concepts and principles to abstract thinking methods such as logical thinking. Junior high school physics exercises need students to explain many physical phenomena, and calculation problems can generally be directly obtained by formulas. Compared with junior high school, the content of physics learning in senior high school has greatly increased in depth and breadth, and the physical phenomena studied are more complicated. And the connection with daily life phenomenon is not as close as junior high school. When analyzing physical problems, we should not only start with experiments, but also establish physical models to explore problems from many aspects and levels. In the process of physics learning, abstract thinking is more than image thinking, and dynamic thinking is more than static thinking, which requires students to master inductive reasoning, analogical reasoning and deductive reasoning methods, especially to have scientific imagination.

Students who have just graduated from junior high school to senior high school generally can't adapt at once and find it difficult to learn physics in senior one. How to do a good job in the connection of physics teaching in junior high school and reduce the learning level of physics in senior high school and junior high school; How to make students adapt to the characteristics of high school physics teaching as soon as possible and overcome the difficulties in learning physics has become the primary task of our senior one physics teacher.
