Physics education in 2 1 century should pay more attention to the cultivation of students' innovative ability. At present, the cultivation of innovative talents is more urgent in China's socialist modernization. As teachers in the new era, we should bravely undertake the historical mission of cultivating innovative talents needed by the motherland and give full play to the special role of scientific and technological innovation in the strategy of rejuvenating the country through science and technology. At present, only new talents with innovative spirit and ability can be continuously cultivated in China. Only in this way can new ideas, new patents and new inventions be constantly produced, it is possible to promote the great progress of national science and technology on the basis of innovation, and the beautiful Chinese dream can be realized at an early date. However, it is impossible to cultivate students' innovative ability overnight. It is a long and complicated process, which requires teachers to actively create conditions in the usual teaching, stimulate students' innovative consciousness and develop their innovative potential. However, the cultivation of students' innovative ability involves many aspects and is related to many disciplines. This paper only talks about how to cultivate students' innovative ability in physics teaching from the perspective of physics teaching and combining the characteristics of physics subjects.

First of all, students' active and dynamic teaching methods should be emphasized in teaching.

The teaching process of physics is not only a process of memorizing and understanding concepts, definitions and physical formulas, but also an active process of thinking and exploring physical phenomena and laws. In the process of this activity, all students are required to take the initiative to participate. In this process, they do not rely on the teacher's teaching, but on the students' own experiments, thinking, analysis and summary. Innovative consciousness begins with students' positive thinking and begins with questioning and asking questions. Discussing a problem in class will arouse students' subjective consciousness, actively think and explore, and help students discover new knowledge and produce new thinking. Therefore, in teaching activities, students should be given free space to develop, and students should have the right to express their views, so that they can express their views on issues and discuss them in class. This not only enlivens the atmosphere, but also makes it easier to mobilize students' initiative and enthusiasm. They will actively think under the guidance of teachers and finally sum up the correct conclusions.

For example, when discussing "the role of force", because there are many examples in daily life, I ask students to think and summarize the conclusions from the examples in life.

The teacher asked the students to talk about the effect of "force" when it acts on objects with specific examples in life.

Students speak:

Student 1: Force can break things.

Student 2: Force can tear paper or break a stick. (and demonstrate)

Student 3: Force can make a stationary car move, and it can also make a moving car stand still. (and demonstrate)

Student 4: Force can change the direction of a moving object. (and demonstrate)

Teacher: Let the students think about the speeches of students (1) and students (2). What effect can they show?

And give another example to illustrate.

Student: Force can deform an object. For example, if you pull a rubber band, it will stretch.

Teacher: Please think about the effects of (3) and (4) students' speeches. And give another example to illustrate.

Student: Force can change the motion state of an object. Because of resistance, the football rolling on the grass slowly stopped.

Teacher: Please summarize the function of strength.

The students spoke enthusiastically at this time and summed up the role of force very accurately. In the whole discussion process, students actively participate, think actively, and draw correct conclusions under the guidance of teachers. It plays an active role in the interaction between teachers and students, which undoubtedly stimulates students' interest in learning and cultivates their habit of positive thinking, and plays an inestimable role in stimulating students' subjectivity and cultivating innovative consciousness.
