基于CBL原理的三明治教学结合网络资源库在小儿外科临床教学中的应用

摘要

Objective To investigate the application of sandwich teaching method based on CBL principle in clinical teaching of pediatric surgery combined with network database. Methods A total of 147 undergraduate students in clinical medicine were selected and randomly divided into experimental group (84 persons) and control group (63 persons). The experiment group used sandwich teaching based on CBL principle + bedside demonstration + network resource library, while the control group adopted tradi-tional teaching + bedside teaching. The teaching effect was evaluated through theoretical and practical ex-aminations and quantitative feedback questionnaires. The t-test of independent samples was performed in two groups, and the scores of the questionnaires were matched by paired t-test. Results The scores of net-work test, case discussion, summary and written test in the experimental group were better than those in the control group [(37.56 ±1.32) vs. (35.10 ±1.25); (27.61 ±0.94) vs. (24.71 ±1.51); (27.02 ±1.11) vs. (26.29±1.30); (88.28±1.97) vs. (83.60±4.58)], the difference was statistically significant. The question-naire survey showed that the students in the experimental group were better than the control group in the learning efficiency, team cooperation, independent thinking, theory connection, and so on. Conclusions The sandwich teaching method based on CBL principle, combined with the network database, is better than the traditional method in the clinical teaching of pediatric surgery, and can promote the theoretical and overall teaching effect, which is worth popularizing.%目的 探讨基于CBL原理的三明治教学结合网络资源库在小儿外科临床教学中的应用及效果评价.方法 选取临床医学七年制儿科专业本科阶段学生147人,随机分为实验组(84人)和对照组(63人).实验组采用基于CBL原理的三明治教学+床旁示教+网络资源库应用,对照组采用传统讲授+床旁示教.教学效果通过理论和实践考试,以及教学反馈量化问卷来评估.采用SPSS 18.0统计软件进行分析,两组成绩行t检验.结果 实验组网络测验、病例讨论、综述、笔试成绩均优于对照组[(37.56±1.32)vs.(35.10±1.25);(27.61±0.94)vs.(24.71±1.51);(27.02±1.11)vs.(26.29±1.30);(88.28±1.97)vs.(83.60±4.58)],差异有统计学意义.问卷调查显示,实验组学生在学习效率、团队合作、独立思考、理论联系实际等方面优于对照组.结论 基于CBL原理的三明治教学结合网络资源库,在小儿外科临床教学中效果优于传统方法,同时促进理论课及整体教学效果的提升,值得推广.
