Objective To assess the effectiveness of flipped classroom based on Chaoxing platform in teaching clinical nu-trition.Methods From September to October 2022,students from 2 nursing classes of Grade 2020 in Guangdong Medical University were conveniently selected as the research objects,and were divided into the flip group(n=38)and the control group(n=36).The students in the experimental group participated in flipped classroom instruction based on Chaoxing plat-form,while the control group was assigned to traditional lecture-based teaching.After teaching,the scores of chapter tests,self-directed learning ability and course satisfaction were compared between the two groups.Results There was no signifi-cant difference in the test scores between the two groups(P>0.05).The total score of the self-directed learning ability scale in the flip group was higher than that in the control group,the difference was statistically significant(P<0.05).In the evalu-ation of the two groups of students on the course,except for the positive description item"improve my learning enthusiasm",the agreement rate of the other items in the flip group were higher than those in the control group,the differences were sta-tistically significant(P<0.05).There was no significant difference in the agreement rate of three negative descriptive items between the two groups(P>0.05).Conclusion The flipped classroom based on the Chaoxing platform is helpful in improv-ing students'satisfaction and learning autonomy in teaching clinical nutrition among undergraduate nursing students.Edu-cators should optimize flipped classroom strategies and adjust the evaluation indicators of teaching effect for specific subjects to maximize the practical significance of the flipped classroom approach.
