In the traditional practice class, it is the practice content and operation steps that teachers have drawn up in advance. The main task of practice students in class is to listen to the teacher's lectures, plug in the circuit according to the experimental instruction, verify the experiment, record the data, and complete the practice report. With the teacher as the main body, there is no more time for students to think and play. Therefore, students lack initiative, and this kind of practice process can't fully arouse students' enthusiasm and activity. Project-driven teaching method can fully arouse students' learning enthusiasm, and combine theoretical knowledge with teaching tasks to help students master corresponding theoretical knowledge while completing tasks and exercising practical ability. This teaching method has improved students' ability to practice engineering, solve practical problems, explore and innovate, and unite and cooperate, and achieved good teaching results.
