"理实一体化"模拟教学在经阴道超声检查技能培训中的应用

Application of simulation teaching of theory-practice integration model in transvaginal ultrasound skill training

目的探索"理实一体化"模拟教学在经阴道超声检查技能培训中的应用效果。方法采用试验对照方法。于2020年12月选取济宁医学院2017级五年制临床医学专业47名学生为研究对象,采用随机数字表法将其分为试验组和对照组,试验组24名学生采用"理实一体化"模拟教学方式,对照组23名学生采用传统教学方式,在医学超声影像学课程授课结束后,通过两组学生考核成绩和问卷调查结果比较两种方法的教学效果。采用t检验或卡方检验比较两组间差异。结果试验组学生超声检查技能考核成绩为(92.40±3.40)分,高于对照组学生的(88.67±2.35)分,其差异具有统计学意义(F=4.35,P<0.001);试验组学生在激发学习兴趣、提高自信心和团队协作能力方面感到满意的人数占比分别为87.5%(21/24)、91.7%(22/24)和83.3%(20/24),高于对照组学生的60.9%(14/23)、56.5%(13/23)和56.5%(13/23),其差异均具有统计学意义(均P<0.05)。结论"理实一体化"模拟教学能够提高学生经阴道超声检查技能水平,得到学生的认可,值得推广应用。

Objective To explore the application effect of simulation teaching of theory-practice integration in transvaginal ultrasound skill training.Methods Experimental control method was used.A total of 47 students from a five-year program of clinical medicine in Jining Medical University were selected as the research objects in December 2020.They were divided into experimental group and control group by random number table method.The experimental group(24 students)adopted simulation teaching of theory-practice integration,while the control group(23 students)adopted traditional teaching.At the end of the course of medical ultrasonic imaging,the related learning effect of students in the two groups was evaluated and compared by examination results and questionnaire survey results.T test and chi-square test were used for comparising between groups.Results The score of ultrasound skills of the experimental group was(92.40±3.40),which was higher than that of the control group(88.67±2.35),and the difference was statistically significant(F=4.35,P<0,001).In the experimental group,87.5%(21/24),91.7%(22/24),and 83.3%(20/24)of the students were satisfied with stimulating their interest in learning,improving their self-confidence and teamwork ability,respectively,which were higher than 60.9%(14/23),56.5%(13/23)and 56.5%(13/23)in the control group,and the differences were statistically significant(all P<0.05).Conclusions The simulation teaching of theory-practice integration can improve students'practical skills of transvaginal ultrasound,which is worthy of popularization and application.
