CBL结合LBL在军事体力劳动影响心血管系统功能教学中的应用

Application of case-based learning combined with lecture-based learning in teaching course on effect of military physical labor on cardiovascular system

摘要

摘要:
目的评价以案例为基础的教学模式（case-based learning, CBL）结合以授课为基础的教学模式（lecture-based learning, LBL）在军事劳动卫生学教学中的效果。
方法选取五年制临床医学专业学生224名作为研究对象，随机分为对照组（n=112）和试验组（n=112）。在军事体力劳动影响心血管功能相关内容授课时，对照组学生采用传统LBL模式，试验组采用CBL结合LBL教学模式。课堂授课结束后，采用随堂测试成绩对比分析和学生问卷调查形式评价授课效果。
结果 CBL结合LBL组的考试成绩显著高于对照组（P<0.01）。在问卷调查中，学生对CBL模式教学效果的评价显著高于传统的LBL模式，对“提高学习兴趣”等10项授课效果指标表现出更高的认可率（9项 P<0.01,1项P<0.05）。
结论在军事体力劳动影响心血管功能相关内容教学中采用CBL结合LBL模式，可以提高授课效果和学生考试成绩，是军事劳动卫生学教学模式研究中值得探索的方向。

Abstract:
AIM To explore the effect of case-based learning (CBL) combined with lecture-based learning (LBL) in teaching courses on Military Labor Hygiene.
METHODS A total of 224 students majoring in 5-year clinical medicine were selected and randomly divided into control group (112 students) and experimental group (112 students). For course on the influence of military physical labor on cardiovascular functions, the control group adopted traditional LBL teaching mode, while the experimental group adopted CBL combined with LBL teaching mode. At the end of the course, the teaching effect was evaluated by comparing the results of in-class test and questionnaire survey of students.
RESULTS The scores of CBL+LBL group were significantly higher than those of control group (P<0.01). The questionnaire survey results showed that the students’ evaluation of the teaching effect of CBL mode was significantly higher than that of traditional LBL mod(P<0.01 or P<0.05).
CONCLUSION CBL combined with LBL improve the teaching effect and students’ test scores in the course on effect of military physical labor on cardiovascular functions. It is a direction worth exploring in the teaching mode research for military labor hygiene courses.
