<正>Objective:A computer-based STS（simulative training system） in providing pre-hospital trauma care at a disaster site was applied to teaching nursing students in the Second Military Medical University

China.This article reports on the teaching effectiveness of this system.Methods:Among 92 participants

46 were in the study group and 46 were in the "control" group. Each student completed a multiple-choice quiz after completing 18 hours（six three-hour sessions） of the study module

and a score was recorded.The simulative training module was completed only by the study group;the "control" group was assigned in-class discussions for the same amount of time covering the same content as the study group.The final course scores

which included both comprehensive and group task-based tests were compared between these two groups.The study used a descriptive and comparative approach for quantitative data analysis.Tests of independency between the multiple choice scores and the simulation scores were also performed.Finally

anonymous surveys were conducted.Results:The study group performed better than the "control" group with a significantly higher average score for the group scenario task-based test score

and consequently the study group’s final course score was significantly higher than the "control" group.As per chi-square tests

no significant associations were found between the multiple choice scores and the simulated training scores.The final surveys showed students overwhelmingly agreed that STS training improved their knowledge and skills

their ability to recognize a potential critical event

and their initial response for trauma care at pre-hospital settings.The survey responses of the study group were noteworthy as they indicated that students recognized the importance of simulative training

appreciated the realism of the simulation

and were able to fight/adjust to the stressful feelings in order to focus on the task.Conclusion:Computer-based STS may be an effective teaching model to help students improve their capability in providing pre-hospital trauma care

and in their effectiveness in disaster response.
