Physics experiment course in senior high school plays a very important role in cultivating students' scientific thinking and scientific inquiry ability. However, in teaching practice, due to large experimental error, poor demonstration effect and lack of experimental conditions, it cannot achieve the expected teaching effect. This study integrates the simulation experiment software into the physics experiment classroom in senior high school, in order to optimize the experimental teaching

... and promote the development of students' inquiry ability. In this study, 45 students from class 5 and 47 students from class 6 of grade 1 in a high school in Beijing were selected as the experimental class and the control class respectively. The demonstration experiment of "synchronous satellite orbit transfer launch" and the exploration experiment of "uniform linear motion" were carried out with the help of simulation experimental software. The results showed the teaching based on simulation experimental software plays a positive role in teachers' experimental teaching, reducing experimental errors, improving self-efficacy and teaching performance. On the other hand, limited by the simulation experiment environment, the simulation experiment could reduce the trial and error opportunities of excellent students, and affect the development of students' innovation ability to a certain extent.
