Abstract: At present, education informatization is vigorously promoted. In view of the problems of single traditional training forms, heavy tasks, and time and space constraints, the college platform introduces the WeChat public platform into the large-scale instrument training mode to explore a new model. The practice shows that the operation of this model stimulates the initiative and innovation of students’ independent learning, and significantly improves their professional cognition, scientific research level and training quality. At the same time, the failure rate of the instrument is effectively reduced, and the use efficiency of the large instrument is improved. In addition, the operation of this mode improves the professional level and professional ability of teachers, and enhances the ability of platform comprehensive services.
