Objective To construct the ecological classroom of epidemiology from the perspective of educational ecology, and evaluate its teaching effects.

Methods Students majoring in five-year prevention in grade 2020 and grade 2019 of Bengbu Medical University were selected as experimental class(95 students) and control class(92 students), respectively.The experimental class adopted the teaching mode of ecological classroom, constantly innovated teaching methods, optimized teaching environment and integrated teaching resources, and regarded teachers, students and the environment as an ecosystem.The control group mainly adopted the traditional teaching mode of "teaching method".The teaching effects in two classes were evaluated after the teaching was completed.

Results The satisfaction with the teaching mode in the experimental class was higher than that in control class, the control class thought that the epidemiology course was more difficult, while the experimental class thought that the learning goal was more oriented to practice, the participation in teaching activities was higher, and the support degree of teaching environment and teaching resources was more satisfied.After epidemiology teaching, the scientific research ability, innovative thinking ability, topic reporting ability, scientific research paper writing ability, community communication ability and teamwork ability in two classes were improved.The improvement degree in the experimental class was better than that in control class(P < 0.05 to P < 0.01).

Conclusions The construction of epidemiology ecology classroom can improve the teaching effects of epidemiology, cultivate students' practice and innovation ability, and promote the in-depth development of education reform.
