案例教学结合多媒体技术在临床小儿外科示教中的应用

目的 探讨案例教学（case based learning,CBL）结合多媒体技术在临床小儿外科示教中的应用效果.方法 将2009级儿科学五年制专业144名学生随机为实验组和对照组,各72人.针对实验组学生实施结合多媒体技术的CBL,针对对照组学生采用传统的多媒体教学.课程结束后对两组学生进行临床示教知识考核,各项考核平均成绩以均数±标准差表示,两组间比较行t检验;同时对实验组学生进行教学满意度调查.结果 实验组学生在技能操作成绩、临床思维评分、平时成绩、理论成绩及总成绩方面均高于对照组学生,差异有统计学意义（P=0.003,P=0.002,P=0.008,P=0.009,P=0.008）.问卷调查结果显示,实验组学生认为CBL结合多媒体技术较传统多媒体教学能够更好地培养自身多方面能力,对学习大有帮助.结论 CBL结合多媒体技术可以提高临床小儿外科示教效果,值得推广.

The application of case-based learning with multimedia teaching in the clinical teaching of pediatric surgery

Objective To explore the application of case based learning（CBL）combined with multimedia teaching in the clinical pediatric surgery.Methods 144 five-year program students of Pediatrics in grade 2009 were randomly and evenly divided into the experimental group using CBL with multimedia teaching,and the control group using multimedia teaching mode.After the end of the course the students of the two groups took clinical teaching knowledge test.The evaluation scores were shown by mean ± standard deviation and comparison was made between the two groups with t test.At the same time,teaching satisfaction survey was conducted among the students of the experimental group.Results The usual results,the theoretical scores and total scores of the students in the experimental group were higher than those of the control group students in the operation skills,clinical thinking,and there was statistically significant difference in P〈0.01.（P=0.003,P=0.002,P=0.008,P=0.009,P=0.008）.The questionnaire survey shows that compared with traditional multimedia teaching,CBL combined with multimedia teaching can preferably culture students＇ various abilities and is beneficial to learning.Condusion The use of CBL combined with multimedia teaching can affirmatively improve the clinical teaching effect in the clinical pediatric surgery,and it deserves to be generalized in the future teaching.
