【Abstract】 Objective To compare and study the effect of two practice models on clinical practice teaching in pediatric orthopedic surgery. Methods A total of 60 5-year undergraduate interns were selected and assigned randomly separately into control group(n=30)and experimental group (disease-based internship group

n=30).The control group took bed-based internship model that interns managed patients with fixed beds.The experimental group took disease-based internship model that interns managed the same disease patients and rotated regularly.Both groups used the same teaching method that the PBL+LBL teaching.At the end of the internship

SPSS18.0 was used to analyze the data

the independent sample t test and chi-square test were used to compare the results of the two groups. Results In the dimensions of theoretical knowledge

medical records written and consolidated results

the score of the experimental group were higher than the control group

the differences were statistically significant(P<0.05).The score of practical skill in two groups was no statistically significant difference(P>0.05).The satisfaction survey showed that the experimental group had higher satisfaction than the control group

the difference was statistically significant(P<0.05). Conclusion The disease-based internship model is better than the bed-based internship model in clinical practice teaching in pediatric orthopedic surgery

and improve the quality of clinical teaching practice.
