Classroom teaching is the main form of school teaching, and teachers impart knowledge to students through classroom teaching. Faced with the pressure of further education, students are not only full of professional courses, but also many quality education courses such as music, physical education and art. And some students with good family conditions have to make up lessons after class, which invisibly increases their academic burden and reduces their free time. In particular, this year, the province issued the "five strict" regulations, which ensured the quality education courses for students, but some major subjects were naturally much less. For example, our physics class used to have five classes a week, but now there are only three classes. How to improve students' learning quality under the situation of reducing the burden? I think we should improve the efficiency of classroom teaching, let students finish proper and effective homework, and try not to take up students' extracurricular time. Now I will talk about some simple views on how to improve the efficiency of physics classroom teaching, hoping to bring you some gains. To improve the efficiency of classroom teaching, we should not only follow the general teaching principles, reasonably arrange the teaching contents, but also flexibly use various teaching methods and means, attach importance to the emotional factors in physics classroom teaching, and constantly explore and find ways and means to improve the efficiency of physics classroom teaching. Let me elaborate on some of my practices. First, establish a good relationship between teachers and students. The so-called "pro-teacher, channel". The relationship between teachers and students is harmonious, and students are naturally willing to listen to your lectures. At this time, the teaching effect in the classroom is definitely good. If students don't want to attend your class, even if you speak well, the teaching effect will be greatly reduced. So this is the premise of improving the efficiency of classroom teaching.
