One month after the class

90 students were randomly selected to participate knee puncture examination

including 39 in experimental group and 51 in control group

and their examination results were recorded and analyzed. The statistical analysis was conducted by t test and chi-square test. Results　The mean scores in experimental group were (84.18±7.21) points

which were statistically higher than these in the control group (80.17±10.51) points

P=0.044. On the other hand

there was no statistical difference between experimental and control group in the aspect of score distribution in each score section. Conclusion　Competitive teaching is beneficial for the improvement of students' overall grades and clinical skills.
