基于移动设备的视频教学方法在整形外科教学中的应用

Application of mobile device-based video teaching in plastic surgery education

目的了解基于移动设备的视频教学方法应用在整形外科教学中的可行性和效果。方法选取北京协和医学院新入学的22名硕士研究生为研究对象,按"规培"地区分为两组。试验组(n=11)为京外"规培"的学生,实施移动视频教学;对照组(n=11)为北京地区"规培"的学生,采用课堂面对面传统教学。第一学期教学结束后,对两组学生进行理论及临床操作理论考试,比较测评结果。应用SPSS 12.0软件进行t检验和卡方检验。结果试验组的客观理论题考试成绩为(38.82±3.22)分,对照组的客观理论题考试成绩为(38.36±2.98)分,两组比较差异无统计学意义(P=0.74);试验组与对照组的临床操作理论考试成绩分别为(46.36±3.44)分、(41.00±5.24)分,两组比较差异有统计学意义(P=0.01);总成绩方面,试验组成绩为(85.18±4.83)分,对照组为(79.36±5.52)分,两组比较差异有统计学意义(P=0.016)。结论采用基于移动设备的教学方法,既可以使学生学习理论知识,又能帮助学生更好地培养临床思维,值得在整形外科教学中进行推广。

Objective:To assess the feasibility and effects of the mobile device-based video teaching in plastic surgery education.Methods:In the study,22 participants were assigned into two groups according to their standardized training area.The intervention group(n=11)which was outside Beijing had an unlimited access to video-based education;the control group(n=11)which was in Beijing received traditional teaching.After the end of the first semester of teaching,the two groups of students were tested on theory and clinical operational theory,and the evaluation results were compared.SPSS 18.0 software was applied for t test and chi-square test.Results:After the first semester,the effect of teaching method was evaluated by the scores of written examination and clinical examination.The average scores of the written test in the intervention group were(38.82±3.22)points,while that in the control group were(38.36±2.98)points,without significant differences between the two groups(P=0.74);the average scores of the clinical examination theory test in the intervention group and the control group were(46.36±3.44)points and(41.00±5.24)points,respectively,with significant differences between the two groups(P=0.01).In term of total scores,the average scores of the intervention group were(85.18±4.83)points,and those of the control group were(79.36±5.52)points,with statistical differences between the two groups(P=0.016).Conclusion:Mobile device-based video teaching in plastic surgery education can not only improve students'performance but also facilitate their clinic skills,which is worth popularizing.
