Abstract: In this study, small class teaching was carried out for some main courses in Agricultural College of Shenyang Agricultural University, such as general theory of crop cultivation and farming. Taking general theory of crop cultivation as an example, students and teachers' feelings on small class teaching were investigated in the form of questionnaire, and the effect and harvest of small class teaching were discussed from the aspects of learning mentality and class efficiency. The results show that small class teaching is a great challenge for teachers, and increases the workload of teachers. In the process of small class teaching, teachers' teaching ability has a greater impact on classroom teaching effect. The treatment of students should be changed from "management" to "guidance". Teachers need to increase collective lesson preparation and communication to enhance the ability of education and teaching. Small class teaching effect is better, but many of the specific implementation rules, still need to constantly sum up experience, improve.

Key words: Small class teaching, Learning attitude, Learning efficiency
