The course of introduction to animal science is complex and involves a wide range of subjects.Based on the requirements of biosafety,it is impossible to lead students to onsite teaching in animal farms.How to let the students get rid of the simple boring theory,strengthen the perceptual understanding,and truly master the course content has put forward new requirements for teachers' teaching.The traditional classroom pure theory teaching method is obviously unable to achieve the teaching purpose.Therefore,teachers are required to have rich practical experience and be able to introduce practical cases in production into the teaching process,so that students can understand the problems in production and the ways and approaches to solve them,strengthen the deep understanding of the course content,improve the quality of classroom teaching,and cultivate students' ability of independent thinking,practical innovation and teamwork.
