基于问题式学习的反思性教学法在外科手术学技能教学中的应用

The application of problem-based learning based reflective teaching in surgical skill teaching

目的探讨基于问题式学习(PBL)的反思性教学法在外科手术学技能教学中的应用效果。方法选取2020年8月至10月于北京大学医学部参加外科手术学课程的临床医学本科生20名作为研究对象,按照随机数字表法将其分为对照组和试验组,每组10名。对照组采用传统教学方法,试验组采用基于PBL的反思性教学法。课程结束后采用操作考核、满意度调查、自我评价等方法评价学生的学习效果。结果试验组导尿术、手术打结、离体肠吻合术成绩和满意度均高于对照组,差异有统计学意义(P<0.05)。试验组学生自我评价得分最高的是团队合作能力和解决问题的能力。结论基于PBL的反思性教学法在外科手术学技能教学中有较好的教学效果。

Objective To explore the application effect of problem-based learning(PBL)based reflective teaching in surgical skill teaching.Methods Twenty clinical medical undergraduates participated in the surgery course in Peking University Health Science Center from August to October in 2020 were selected as the research subjects,and they were divided into the control group and the test group according to the random number table method,with ten students in each group.The control group used traditional teaching methods,and the test group used PBL based reflective teaching methods.After the course,the students’learning effects were evaluated by means of operation assessment,satisfaction survey and self-evaluation.Results The results of urethral catheterization,surgical knotting and intestinal anastomosis in vitro and satisfaction in the test group were higher than those in the control group,the differences were statistically significant(P<0.05).The students in the test group scored the highest in self-evaluation,which was the ability of teamwork and problem-solving.Conclusion PBL based reflective teaching method shows a good teaching effect in the surgical skills teaching for undergraduates.
