BACKGROUND
Computer-based video training (CBVT) provides flexible opportunities for surgical trainees to learn fundamental technical skills, but may be ineffective in self-directed practice settings because of poor trainee self-assessment. This study examined whether CBVT is effective in a self-directed learning environment among novice trainees.
METHODS
Thirty novice trainees used CBVT to learn the 1-handed square knot while self-assessing their proficiency every 3 minutes. On reaching self-assessed skill proficiency, trainees were randomized to either cease practice or to complete additional practice. Performance was evaluated with computer and expert-based measures during practice and on pretests, posttests, and 1-week retention tests.
RESULTS
Analyses revealed performance improvements for both groups (all P < .05), but no differences between the 2 groups (all P > .05) on all tests.
CONCLUSIONS
CBVT for the 1-handed square knot is effective in a self-directed learning environment among novices. This lends support to the implementation of self-directed digital media-based learning within surgical curricula.
背景
基于计算机的视频培训（CBVT）为外科实习生提供了学习基本技术技能的灵活机会，但由于实习生自我评估能力较差，在自主练习环境中可能效果不佳。本研究探讨了CBVT在新手实习生的自主学习环境中是否有效。
方法
30名新手实习生使用CBVT学习单手方结，同时每3分钟自我评估一次熟练程度。在达到自我评估的技能熟练程度后，实习生被随机分为停止练习组或完成额外练习组。在练习期间以及在预测试、后测试和1周保留测试中，使用基于计算机和专家的方法评估表现。
结果
分析显示两组的表现均有改善（所有P < 0.05），但在所有测试中两组之间无差异（所有P > 0.05）。
结论
单手方结的CBVT在新手的自主学习环境中是有效的。这为在外科课程中实施基于自主数字媒体的学习提供了支持。
