目的 探讨微课程结合以案例为基础的教学模式(CBL)在低温影响心肺功能教学中的效果.方法 选取60名五年制临床医学专业学生作为研究对象.随机分为对照班(5组,6人/组)为传统教学班,试验班(5组,6人/组)为微课结合CBL联合教学模式班.课程结束后,通过成绩分析和问卷调查进行教学效果评价.学生对教学效果的评价以百分比表示.结果 试验组学生的总成绩明显高于对照班(P＜0.01).问卷调查的结果显示,学生对微课结合CBL模式的教学效果评价明显优于传统的授课方式,不仅有助于提高学生的学习兴趣和独立思考问题的能力,而且有利于知识点的理解和掌握.结论 微课结合CBL模式教学法在低温影响心肺功能教学中的应用可以明显提高课堂教学效果,加深学生对理论知识的掌握,提高学生的综合能力.","AIM To evaluate the practical efficiency of microlectures combined with case-based leaing in the instruction of low temperature influence on the cardiac and pulmonary functions.METHODS A total of 60 students of a 5-year medical curriculum were chosen for this study.The enrolled students were randomly divided into control group (Class A,30 students) and experimental group (Class B,30 students).The traditional teaching method was used for instruction in Class A,while the new method of microlectures combined with case-based leaing was used in Class B.In both classes,the students were subdivided into 5 groups (6 people per group).At the end of the course,effects of teaching were evaluated by score analysis and questionnaire survey.Studentsevaluation of the teaching effectiveness was expressed as percentage.RESULTS The total score in experimental group was significantly higher than that in control group (P ＜0.01).The questionnaire results revealed that microlectures combined with case-based leaing was significantly more efficient than the traditional teaching method.The new method not only enhanced students leaing interests and independent thinking,but also improved their knowledge-acquiring ability.CONCLUSION The application of microlectures combined with case-based leaing in the instruction of low temperature impact on cardiac and pulmonary functions significantly improves the effect of classroom teaching,helps the students better master the theoretical knowledge and improves their comprehensive ability.
