"Beer Fermentation Engineering Experiment" is a highly practical experiment in brewing technology, which is of great significance to improving students' practical ability. Participatory teaching can guide students to actively participate in experimental courses, and the participatory teaching model can guide students to actively participate in the teaching process, maximize the role of students as the main body, and improve the teaching effect of experimental courses [1]. The introduction of participatory teaching into the teaching of "Beer Fermentation Engineering Experiment" has changed the teaching mode and promoted the interaction between teaching and learning. Students have changed from "passive instillation" to "active learning", which effectively improved students' active exploration, independent analysis and The ability to deal with exercises is conducive to the cultivation of innovative spirit and enhance the quality of experimental teaching.
