摘　　要：目的探讨利用X片为载体的影像实物演示教学在医学影像技术本科专业X线摄影检查技术学实验课程教学中的应用价值。方法2015级医学影像技术本科生共63名,随机均分为3组进行胸腹部X线摄影检查技术部分实验课程的教学。实验课程前的准备工作和实验用机器均相同,作为实验组,A组和B组在实验教学过程中添加了以X片为载体的影像实物演示环节。通过模拟上机考核和小测试评估两种方法的教学效果差别,通过问卷调查评估X片为载体的影像实物演示教学在医学影像技术本科生X线摄影检查技术学实验教学中的接受度。结果实验组的模拟上机考核成绩[(7.36±1.39)分]和小测试成绩[(4.24±2.01)分]均高于对照组[(6.05±1.28)和(3.10±1.48)],差异均具有统计学意义(P<0.01,P=0.024)。实验组的问卷结果为,学生100%认可X片为载体的影像实物演示法在X线摄影检查技术学实验教学中的应用。结论将以X片为载体的影像实物演示教学用到医学影像技术本科专业X线摄影检查技术学实验教学中,有助于该专业本科生对新知识的接受,加深其对知识点的印象,提高教学效率,值得开展和推广。Objective To study the application value of practical demonstration of actual X-ray film images in the experimental teaching of radiography technology courses in medical imaging undergraduates.Methods A total of 63 medical imaging undergraduates of Grade 2015 were randomly divided into three groups to receive part of the experimental courses about chest and abdomen radiography examination.Their pre-class work and machine were the same.As the experimental group,group A and group B added demonstration with X ray film images,while group C(control group)did not.The different teaching effects of the two methods were evaluated by simulate practical assessment and quiz.The accepting degree of demonstration method was evaluated in accordance with questionnaire survey.Results The scores of simulated practical assessment(7.36±1.39)and quiz(4.24±2.01)in experimental group were significantly higher than those of(6.05±1.28)and(3.10±1.48)in the control group,with a statistically significant difference(P<0.01,P=0.024).Questionnaire survey showed that the experimental group were 100%accepted practical demonstration of X ray film images.Conclusion The application of practical demonstration of X-ray film images in radiology technology experimental courses can help undergraduates to accept new knowledge,deepen impression on knowledge and improve teaching effect,which is worth developing and popularizing.
