Abstract: With the deepening of teaching reform and the continuous improvement of quality education requirements, in order to highlight the main position of students in experimental teaching, a “reverse” thinking experimental teaching mode based on fault circuit is proposed. Through the diagnosis, analysis, and elimination of fault circuits, students can be trained to solve practical problems independently, and they can also inspire students’ ability to develop ideas and innovation. At the same time, it also adds interest and challenge to the experimental project, which can stimulate students’ experimental interest to a greater extent. According to the comparison of student performance distribution between the experimental class and the non-experimental class, the experimental class has greatly improved in terms of overall theory and comprehensive ability, and a set of feasible and efficient training mode is explored for cultivating high-quality professional and technical personnel.
