目的 探讨基于案例学习(case-basedlearning,CBL)教学方法在医学影像技术专业本科实习教学中的应用效果。方法 选择四川大学2015级四年制医学影像技术专业46名本科实习生为研究对象,将其平均分为实验组和对照组,每组23人。实验组采用CBL教学方法,对照组采用基于讲授学习(lecture-basedlearning,LBL)教学方法。实习结束后,对两组学生进行医学影像技术理论和操作考核,并对教学效果进行问卷调查。结果 实验组学生理论考核的主观题成绩、总分、操作考核成绩均高于对照组,差异均具有统计学意义[(28.29±2.18)分比(23.50±3.34)分、(74.17±6.79)分比(69.46±6.02)分、(75.75±5.37)分比(70.42±5.88)分,均P＜0.05];问卷调查显示,实验组在学科兴趣的激发、课堂气氛的调动、临床思路的培养、自学能力的锻炼、疑难问题的分析5个方面均优于对照组,差异均有统计学意义[4(3,4)分比3(2,3)分、4(3,4)分比2(2,3)分、4(3,4)分比2(2,3)分、4(3,4)分比2(2,2)分、3(3,4)分比2(2,3)分,均P＜0.05]。结论 CBL教学方法在医学影像技术专业本科实习教学中的合理运用,有助于提高学生的临床分析能力、实际操作能力、学习积极性和自学能力。
Objective To explore the application of case-based learning method in the practice teaching for medical imaging technology undergraduates.Methods A total of 46 undergraduate interns from the 2015 four-year medical imaging technology of Sichuan University were recruited.They were divided into 2 groups:experimental group(23 persons) and control group(23 persons).Case-based learning method was used in experimental group,and the traditional lecture based learning method was used in control group.The theoretical-test scores,operational-test scores and questionnaire results of the two groups were compared.Results The subjective,total and operational scores of the experimental group were higher than those of the control group,with statistical significance [(28.29±2.18)vs (23.50±3.34),(74.17±6.79)vs(69.46±6.02),(75.75±5.37)vs(70.42±5.88),all P<0.05].The stimulation of subject interest,the mobilization of classroom atmosphere,the cultivation of clinical thinking,the exercise of self-study ability and the analysis of difficult problems were better than those of the control group.The differences were statistically significant [4 (3,4) vs 3 (2,3),4 (3,4) vs 2 (2,3),4 (3,4)vs 2 (2,3),4 (3,4) vs 2 (2,2),3 (3,4) vs 2 (2,3),all P<0.05].Conclusions Case-based learning method in the practice teaching of medical imaging technology may improve undergraduates'clinical analysis ability,practical operation ability,learning enthusiasm and self-learning ability.
