不同反馈方式对腹腔镜模拟培训教学的影响

Impact of different feedback methods on the education of laparoscopic simulation training

目的探讨在持续两周的培训课程中,不同反馈方式对腹腔镜模拟培训学习者训练效果的影响。方法以2017年8月至2018年4月在新疆医科大学第一附属医院微创技能培训中心参加腹腔镜模拟培训的98名学员为研究对象,分为三组。Group 1(32人):训练过程中只观看视频教程,不接受指导教师反馈;Group 2(33人):训练过程中可全程观看视频教程,训练过程中指导教师随时进行反馈(即时性反馈);Group 3(33人):训练过程中可全程观看视频教程,每个项目训练结束后接受指导教师总结性反馈。比较培训前、后各组考核操作时间和考核评分的差异,以及培训后各组之间考核操作时间和考核评分的差异。采用STATA 11.0软件进行卡方检验和t检验。结果三组培训后的考核评分均高于培训前(P<0.05),考核操作时间均短于培训前(P<0.05)。培训后,考核操作时间Group 3高于其他两组(P<0.05);考核评分,Group 3高于其他两组(P<0.05);但其他两组差异无统计学意义(P>0.05)。三组训练周期结束后所花费的训练时长及重复次数差异有统计学意义(P<0.05),Group 3达到合格水平所花费的训练时长及重复次数小于其他两组(P<0.05)。结论在腹腔镜模拟培训中,总结性反馈相较于其他两组能够很大程度上加快学习速度,提高训练效率。

Objective To investigate the impact of different feedback methods on the training effects of laparoscopic simulation training learners in two-week training course.Methods A total of 98 trainees receiving simulation laparoscopic training from August 2017 to April 2018 in The First Affiliated Hospital of Xinjiang Medical University were randomized into three groups,including Group 1(n=32),watching video tutorials only;Group 2(n=33),watching video tutorials and receiving immediate feedback;Group 3(n=33)watching video tutorials and receiving conclusive feedback.All the trainees received assessment before and after the training.The differences of assessment scores and operation time before and after the training were compared among the three groups.Chi-square test and t test were conducted by STATA 11.0.Results The assessment scores of the three groups were significantly improved after the training than before(P<0.05),and the operation time of the three groups were significantly shorter than before(P<0.05).The assessment scores and operation time of Group 3 after the training were significantly better than the other two groups(P<0.05),and the assessment scores of Group 3 were higher than those of the other two groups(P<0.05),but there was no significant difference between the other two groups(P>0.05).There were significant differences in training duration and repetition times among the three groups(P<0.05).The training duration and repetition times of Group 3 were significantly less than those of the other two groups(P<0.05).Conclusion Compared with the other two groups,conclusive feedback can greatly accelerate learning and improve training efficiency in laparoscopic simulation training.
