Abstract: Based on the sound speed measurement experiment, taking the standing wave method as an example, this paper makes a theoretical exposition and error analysis on the sound speed measurement experiment. The student-centered and multi-step experimental research is carried out. The teachers demonstrate the principle and significance of the experiment on the Internet, design the experimental scene at home, reproduce the experimental process, understand the experiment, and further optimize the experimental scheme after entering the laboratory Now the experimental process is in-depth exploration of the experiment, a variety of forms of learning, experience the experimental process, students have a clearer understanding of the sound speed measurement experiment, which is conducive to understanding the propagation of sound waves in the medium and standing wave synthesis and other theoretical knowledge, and helps teachers further improve their teaching.<br>Key words: sound speed measurement; student-centered; various forms<br>
