| 目的 探讨"虚实结合"的实践教学在《医学影像设备学》中的应用效果。方法 以齐齐哈尔医学院2018级医学影像技术专业学生为观察组，在《医学影像设备学》实践教学采用"虚实结合"的教学方法，实物参观教学（8学时）、实验箱电路测量教学（20学时）、虚拟仿真教学（16学时）。2017级医学影像专业（对照组）没有采用虚拟仿真教学。比较两个年级学生授课效果和学生成绩。采用SPSS 17.0行t检验和卡方检验。结果 2018级观察组学生实践成绩提高，与2017级对照组比较差异有统计学意义（t=6.44，P=0.007）；观察组授课满意度为100%，两组授课满意度比较差异有统计学意义（χ2=5.25，P=0.022）。结论 "虚实结合"的教学方式，能够有效提高学生的动手操作能力，加强了对抽象性原理的认知，并且解决了实物教学中无法完成的设备故障分析、大型设备拆解与安装等的教学难题。 |

| Objective To explore the application effect of the "combination of virtuality and actuality" practical teaching on Medical Imaging Equipment. Methods The 2018 medical imaging technology students of Qiqihar Medical University were taken as the observation group, and the study adopted teaching method of "combination of virtuality and reality" in the practical teaching of Medical Imaging Equipment, including in-kind visit teaching (8 learning hours), experimental box circuit measurement teaching (20 learning hours) and virtual simulation teaching (16 learning hours). Besides, the 2017 medical imaging major students (control group) did not conduct virtual simulation teaching. The teaching effect and student achievement were compared between the two groups, and SPSS 17.0 was used to conduct t test and chi-square test. Results There was significantly improvement in the practical performance of the students in the observation group compared with the control group (t=6.44, P=0.007); the teaching satisfaction of the two groups was significantly improved (χ2=5.25, P=0.022), and the teaching satisfaction degree was 100%. Conclusion The teaching method of "combination of virtuality and reality" can effectively improve students' hands-on ability, strengthens their cognition of abstract principles, and solves the problems of equipment failure analysis, disassembly and installation of large-scale equipment that cannot be completed in physical teaching. |
