PCMC教学法结合精品微课在医学影像学教学中的应用

Application of PCMC plus quality micro-curriculum in instruction of medical imaging

目的:探究医学影像学精品微课应用效果。方法:选取皖南医学院2018级影像专业本科生作为教学研究对象,随机划分成对照组和研究组,对照组学生在医学影像诊断学、医学超声影像学和介入放射学教学采用典型病例为基础-临床问题导向的(PCMC)教学方法,研究组学生在PCMC教学方法的基础上同时加入医学影像学精品微课《消化系统少见病变的影像诊断》。教学结束后,对两组学生的教学效果开展问卷分析,同时对两组学生的医学影像诊断学、医学超声影像学和介入放射学3门课期末考试试卷涉及消化系统成绩得分统计分析比较差异。结果:研究组学生对提高学习主动性、影像诊断思维的锻炼等5个维度的认可度均高于对照组(P<0.05)。研究组学生在医学影像诊断学、医学超声影像学和介入放射学3门期末考试涉及消化系统试题得分均高于对照组的学生(P<0.05)。结论:精品微课有助于医学影像学教学效果的提升。

Objective:To observe the outcomes of problem-originated clinical medical curriculum(PCMC)combined with quality micro-curriculum in instruction of medical imaging.Methods:Undergraduates majoring in medical imaging,enrolled in Wannan Medical College in 2018,were included as study subjects,and randomized to control group and observational group.Students in the control group were taught with simple PCMC based on the typical cases for medial imaging diagnostics,medial ultrasound imaging and interventional radiology,and those in the observational group were given additional quality micro-curriculum Imaging Diagnosis of Rare Diseases in Digestive System besides the teaching in control group.Questionnaires were used to survey on the teaching effect in both groups upon completion of the curriculum.In addition,the final scores on medical imaging diagnostics,medial ultrasound imaging and interventional radiology were statistically summed up and compared between groups.Results:Students in the observational group had higher consensus in the five dimensions such as improving learning initiative and exercising of image diagnostic thinking as well as the scores in the final examination of curriculums of medical imaging diagnostics,medial ultrasound imaging and interventional radiology involved in the diseases of digestive system than those in the observational group(P<0.05).Conclusion:Quality micro-curriculum can contribute to improving the teaching effect of medical imaging.
