Abstract:Objective：This study aims to evaluate the quality of the medical education environment at a certain grade A tertiary hospital in Suqian using the DREEM scale，explore medical students' comprehensive perceptions of the educational environment and its influencing factors，and provide empirical evidence for optimizing the clinical teaching system. Methods： A cross-sectional survey was conducted with 240 randomly selected medical students using the revised DREEM scale（48 items）. Data were analyzed via one-way ANOVA and correlation analysis using SPSS 23.0. Results：The total score for the educational environment was 186.90±31.91（77.88% of the maximum），indicating a “good” level. Significant differences in social perception were observed across majors（F=3.219，P=0.003）. Strong positive correlations were identified between the educational environment and learning perception（r=0.732），teacher perception（r=0.637），and academic perception（r=0.822）（P ≤ 0.01）. Weak areas included teacher-centered instruction（3.54/5），classroom experience（3.44/5），and curriculum preferences（3.55/5）. Conclusion： Systematic improvements to the educational environment should focus on Problem-Based Learning（PBL）reform，optimizing teacher-student interaction mechanisms，and restructuring learning spaces.
