摘　　要：[目的]探讨认知负荷理论在骨科多媒体教学应用中的价值。[方法]随机抽取200名北华大学第一临床医学院2008级临床医学专业本科生为研究对象,将其平均分为试验组和对照组;参考人民卫生出版社第7版教材骨科学部分教学大纲,以最大程度降低外在认知负荷为目的设计多媒体教学课件,对试验组学生实施骨科教学;同时参考骨科部分教学大纲,以有限时间内向学生讲授尽可能多知识为原则,按章节设计多媒体课件,对对照组学生实施教学;最后以问卷调查及测试方式,比较两组学生测试成绩及各指标有无显著性差异。[结果]试验组学生测试成绩明显高于对照组,两组比较差异有统计学意义(P﹤0.01);问卷调查显示,试验组学生对骨科学习更有兴趣,专业知识的掌握水平亦较高,与对照组相比差异有统计学意义(P﹤0.05);在多媒体教学过程中试验组学生思维能力及临床工作能力均得到很大提高,同时对课件设计有较高的满意度,与对照组相比差异有统计学意义(P﹤0.05)。[结论]基于认知负荷理论,巧妙运用语音、图片等方法设计骨科多媒体课件,可以有效地减轻外在负荷,从而使学生能够轻松、牢固地掌握骨科理论知识。[Objective]To study the application of cognitive load in in orthopedics teaching through multimedia.[Methods]200 clinical medical students were randomly divided into two groups.The students of experimental group were taught orthopaedic knowledge through multimedia.In order to minimizing the external cognitive load,the multimedia was designed based on the cognitive load theory before using.At the same time,the students of control group were taught through traditional multimedia courseware.Within a limited time,the students were taught as mush knowledge as possible.After teaching,all the students were accepted the test and questionnaire survey.Compared the effect of two kinds of multimedia.[Results]The score of experimental group＇ students was significantly higher than of control group（P﹤0.01）.The students of experimental group had more interested in orthopaedic learning and the real level of mastery was higher than the control group（P﹤0.05）.The thinking ability and the clinical ability of experimental group were higher.At the same time,they had higher degree of satisfaction with the multimedia courseware（P﹤0.05）.[Conclusion]Basing on cognitive load theory in orthopedics teaching,multimedia can make students study easily and effectively and grasp orthopaedic theory knowledge.
