Objective　To evaluate the teaching effect of Emergency Nursing practice course using scenario simulation teaching combined with formative assessment. Methods　The subjects were selected from vocational nursing students of Batch 2015 (control group

n=49) and Batch 2016 (intervention group

n=40). The control group adopted the scenario simulation teaching method

and the intervention group added formative assessment on the basis of simulation teaching. The end-of-term theoretical scores of Emergency Nursing and the scores of students' general self-efficacy scale were used as evaluation tools. SPSS 22.0 statistical software was used for data processing and analysis. Results　 The scores of the intervention group (85.20±8.05) were higher than those of the control group (79.73±8.46)

with statistical significance (P<0.05). The scores of self-efficacy in both groups were improved

while the scores of the control group after the course (2.68±0.42) were higher than those before the course (2.61±0.47)

but there was no statistical significance. The scores of the intervention group after the course (2.78±0.43) were higher than those before the course (2.62±0.43)

with statistical significance. Conclusion　The application of scenario simulation teaching combined with formative assessment in the practical course of Emergency Nursing can be helpful to improve students' self-efficacy and comprehensive ability of first aid.
