基于标准病例的案例教学法在普外科见习教学中的应用探讨

Discussion the Application of CBL Based Standardized Patients for Clinical Teaching in Forensic Surgery

目的:探讨基于标准病例(SP)的案例教学法(CBL)在普外科见习教学中的应用效果。方法:选取2014年6月至2015年6月我院见习的五年制临床本科医学生共112人,利用随机数字表的方法将其分为对照组和研究组,两组人数各56人。对研究组采取基于SP的CBL教学法,而对照组则使用传统临床带教方法,1个月后对理论、技能进行评价,并对学生和教师的满意进行问卷调查。结果:在技能考核和病例分析方面,研究组学生的得分显著高于对照组(P<0.05),理论成绩无明显差异(P>0.05)。对学生满意度的调查中,在"课堂气氛活跃"、"对学习兴趣的激发"、"利于理论与实践结合"以及"有利于形成正确临床思维"四个方面,研究组的满意度显著高于对照组(P<0.05)。在对教师满意度调查中,认为试验组教学法的效率要高于对照组教学法(P<0.05),而在"易实施性"满意度低于对照组教学法(P<0.05),在"可操作性"方面差异无统计学意义(P>0.05)。结论:与传统教学模式比较,基于SP的CBL教学法具有显著的优势,能更直观的展示某种疾病的特征,使学生通过实践巩固对基础知识的记忆,值得进一步探索并推广。

Objective： To discuss the efficacy of CBL based standardized patients for probationersin forensic sursery. Methods： Selected 112 five year clinical undergraduate medical students who were practicing in our hospital from June 2014 to June 2015, They were placed into the study group and the control group by random number table, 56 cases in each. The study group was given CBL teach- ing method, while the control group was given traditional teaching method. One month later, theoretical and technical achievements were evaluated. And the degree of satisfaction of probationers and teachers were investigated by questionnaire. Results： In the skills assessment and case analysis, the score of the study group was significantly higher than that of the control group （P〈0.05）. There was no significant difference in theoretical achievements （P〉0.05）. In ＂active classroom atmosphere＂, ＂interest in learning＂, ＂to combine theory with prac- tice＂and＂the formation of correct clinical thinking＂, the satisfaction of study group was significantly higher than the control group（P〈0. 05）. In the investigation of teachers＇satisfaction, the efficiency of case teaching method of study group was higher than that of the control group （P〈0.05）. However, in terms of ease of implementation was significantly lower than control group （P〈0.05）, it was no significant difference in the ＂maneuverability＂ （P〉0.05）. Conclusion： Comparing with the traditional teaching mode, the CBL based SP has more ad- vantages. It is worth to spread the CBL teaching method based on SP, because of it being more intuitive to show the characteristics of certain diseases and make students consolidating the memory of basic knowledge through practicing.
