PBL结合情景教学在核应急医学救援教学中的应用

Application of PBL combined with situational teaching in medical rescue of nuclear emergency teaching

目的探讨以问题为基础的学习(problem-based learning,PBL)结合情景教学在核应急医学救援教学中的应用效果。方法选择陆军军医大学2017级100名学员为教学对象,将核应急医学救援课程前20个学时的教学设为对照组,后20个学时的教学设为实验组。对照组采取传统讲授法进行教学;实验组理论教学以PBL教学模式开展,技能实践教学则采用情景教学;采用理论考试、技能考核和问卷调查的形式对两组学员进行考查。采用SPSS 17.0进行卡方检验。结果理论考试成绩:实验组(77.10±8.11)分,对照组(73.97±7.93)分,两组差异存在统计学意义(P<0.01);技能考核成绩:实验组(78.40±6.35)分,对照组(71.04±7.51)分,两组差异存在统计学意义(P<0.01);从理论考试和技能考核结果、学员自评情况来看,实验组各项均优于对照组,差异有统计学意义(P<0.05)。结论与传统讲授法相比,PBL结合情景教学能提高学员的积极性,增强学员自主学习能力,促进其熟练掌握辐射防护相关知识和技能,培养学员团队合作精神,锻炼学员动手实践能力。

Objective To explore the application effect of problem-based learning(PBL)combined with situational teaching in medical rescue of nuclear emergency teaching.Methods The 100 students from Batch 2017 of the Army Medical University were selected as the teaching objects,and the nuclear emergency medical lessons were divided into two parts:the control group(the first 20 lessons)and the experimental group(the last 20 lessons).The control group adopted traditional teaching method,the experimental group adopted PBL teaching mode for theoretical teaching,and situational teaching method for skill practices.The teaching effect of the two groups of students were examined by theoretical examination,skill practical assessment and questionnaire survey.SPSS 17.0 was used for chi-square test.Results Theoretical examination results of experimental group(77.10±8.11)were higher than those of control group(73.97±7.93),with significant differences(P<0.01).Practical assessment results of experimental group(78.40±6.35)was higher than those of control group(71.04±7.51),with significant differences(P<0.01).Concerning the results of theoretical examination,practical assessment and student self-evaluation,the experimental group was superior to the control group in all aspects(all P<0.05).Conclusion Compared with traditional teaching methods,the PBL combined with situational teaching could encourage the learning interest of students,enhance their ability of independent learning,promote them to master the knowledge and skills of medical rescue of nuclear emergency adroitly,cultivate their team spirit and elevate the practical ability of students.
