Objective To explore the effects of simulation teaching on undergraduate nursing students′ perception of learning environment, and to provide references for improvement of teaching environment and results. Methods Simulation teaching was applied in the practicum sessions of community nursing course for 85 undergraduate nursing students: home visits contents from home care chapter were compiled into a simulation scenario, and standardized patients were trained; the scenario and standardized patients were used in simulation teaching.Before and after the teaching, students were evaluated with the Dundee Ready Education Environment Measure (DREEM). Results The scores of DREEM and four dimensions after simulation teaching were higher than those before the teaching （P＜0.05，P＜0.01）. Conclusion The application of simulation teaching in the practicum sessions of community nursing course can improve students′ perception of learning environment, and boost their active involvement in learning.
