PBL教学法与3D-slicer影像重建技术在长学制医学生神经外科临床实践教学中的应用

目的  探讨在长学制临床医学专业学生神经外科临床实践教学中，以问题为中心教学法（problem-based learing，PBL）联合3D-slicer影像重建技术教学模式的应用效果。方法  选择在我科2019年4月－2019年6月进行神经外科临床实践教学的62名临床医学八年制的长学制学生为研究对象，学生随机分为试验组和对照组。对照组采用传统授课教学模式，试验组给予PBL教学法联合3D-slicer影像重建的模式进行教学。教学效果的评价采用临床实践考核和理论考核成绩，迷你临床演练评估（mini-clinical evaluation exercise，Mini-CEX）考核以及学生问卷调查。结果  试验组临床实践教学成绩，理论考核成绩以及Mini-CEX评估成绩显著高于对照组(均P<0.05)。通过问卷调查发现，试验组学生对新教学模式下的课堂气氛、影像阅片效果、手术讲解情况和教学效果满意度高于对照组(均P<0.05)。结论  在临床医学长学制神经外科临床教学实践中，采用PBL教学法联合3D-slicer影像重建技术的教学模式能激发学生对于神经外科的学习兴趣和学习主动性，提高学习效率，改善教学效果。

Application of combining PBL teaching method with 3D-slicer image reconstruction technology in neurosurgical clinical practice teaching for long-term-system medical students

Objective  To explore the application of problem-based learning (PBL) combined with 3D-slicer image reconstruction technology in neurosurgical clinical practice teaching for long-term-system medical students.  Methods  A total of 62 long-term-system medical students underwent neurosurgical clinical practice teaching in our department from April 2019 to June 2019 were selected. They were randomly divided into experimental group and control group. The control group received traditional teaching mode,  while the experimental group was given PBL teaching method combined with 3D-slicer image reconstruction mode. The teaching effect was evaluated by   clinical practice test,  theory examination， mini-clinical evaluation exercise (Mini-CEX) and student questionnaire. Results   The clinical practice test results,  theoretical assessment results and Mini-CEX results (all P<0.05) in experimental group were significantly higher than those in control group. According to the questionnaire survey,  students in experimental group were more satisfied with the class atmosphere,  radiological image evaluation,  operation explanation and satisfaction of teaching than those in control group ( all P<0.05). Conclusion  In the neurosurgical clinical practice teaching in long-term-system medical students,  PBL teaching method combined with 3D-SLicer image reconstruction technology can stimulate students' interest and initiative in neurosurgical practice learning,  improve the learning efficiency and the teaching effect.
