Objective To explore the effect of counterexample and micro video filming in cardiopulmonary resuscitation training for nursing students. Methods A total of 40 nursing students pursuing associate′s degree were randomly divided into a control group and an observation group, with 20 students in each group. Conventional teaching was used in the control group and counterexample micro video filming was employed in the observation group. The teaching effects were evaluated after training. Results The observation group had significantly higher scores of cardiopulmonary resuscitation exam,success rate of simulated rescue,evaluation of tea-ching, and significantly lower incidence rates of error-prone points, than the control group（P＜0.05,P＜0.01）. Conclusion Application of counterexample micro video filming can effectively improve the quality of cardiopulmonary resuscitation training,cultivate students′ critical thinking ability and inspire students′ learning interest.
