以问题为基础的学习在心电图学中的实验研究

Experimental Research on Problem-based Learning for Electrocardiogram

目的:探讨以问题为基础的学习(PBL)在心电图教学中的可行性和有效性。方法:实验组采用PBL教学法,对照组采用传统的讲授法。以考试成绩和自制的问卷调查作为评价方法。结果:在心电图学习结束时的理论成绩和案例分析成绩两组均有差异(t=2.76,P<0.01;t=1.95,P<0.05);学习结束半年后再次考试,两组案例分析成绩有统计学差异(t=1.76,P<0.05);91.2%的学生认为此教学方法很好,能提高学习心电图的兴趣;85.3%认为这种教学法能提高自学能力和分析问题的能力。结论:PBL在心电图教学的近期效果和远期效果都比较理想,绝大部分学生给予充分肯定和赞同。

Objective：Research on the feasibility and the availability of problem-based learning （PBL） for electrocardiogram（ECG）. Method：The experiment group received PBL while the control group took completely traditional teaching method. The evaluation approaches included examination,questionnaire. Results：It is significant difference in the theoretical record and case analysis （t= 2.76,P〈0.01;t=1.95,P〈0.05）,between the experiment group and control group after learning ECG immediately. The marks gained for case analysis （t=1.76,P〈0.05）,by experiment students are significantly higher than those by control students. More than 91.2% students think that PBL is a very good method for their learning and promote their interest in ECG. More than 85.3% students thought that the competence of self-learning and analysis problem will be improved by PBL. Conclusion：The short term effect and forward effect are good by PBL in ECG. The most of students support this new approach of learning.
