摘　　要：目的探讨三维重建数字模型结合基于问题学习(problem-based learning,PBL)教学方法在肿瘤放射治疗学靶区勾画教学中的应用效果。方法采用试验对照方法,选取2020年1月至2021年1月在哈尔滨医科大学附属肿瘤医院参加肿瘤放射治疗学住院医师规范化培训的30名学员为研究对象,采用随机数字法将其分为试验组和对照组,每组15名学员。试验组采用三维重建数字模型结合PBL教学方法,对照组采用PBL教学方法。培训后对两组学员进行理论知识考核、临床技能考核和问卷调查。结果试验组学员理论知识考核成绩[(89.19±4.59)分比(85.21±2.32)分]、临床技能成绩[(88.01±3.16)分比(81.05±4.12)分]高于对照组学员,其差异均具有统计学意义(均P<0.01)。问卷调查结果显示,试验组学员对其教学方法提高学习效率的评分[(3.75±0.62)分比(2.89±0.53)分]、教学方法提升靶区勾画技能的评分[(4.03±0.56)分比(3.53±0.67)分]高于对照组学员,其差异均具有统计学意义(均P<0.05)。结论三维重建数字模型结合PBL教学方法应用于肿瘤放射治疗学靶区勾画教学,有助于提高住院医师的理论知识成绩、临床技能成绩及靶区勾画基本操作技能,有助于提高住院医师的学习效果。Objective To discuss the application outcomes of a 3D reconstruction digital model combined with problem-based learning(PBL)in the training of tumor radiotherapy target delineation.Methods Using the experimental control method.From January 2020 to January 2021,30 trainees from the program of standardized residents training of oncology radiotherapy in Harbin Medical University Cancer Hospital were selected as the research objects.Random sampling was used to divide them into an experiment group and a control group with 15 in each.The experiment group adopted PBL method supported by 3D reconstruction digital model,and the control group was trained by the PBL teaching method only.After the training,the two groups of trainees were evaluated on theoretical knowledge,clinical practice,and investigated by questionnaire surveys.Results The experimental group's theoretical evaluation score is(89.19±4.59),which is higher than the control group's(85.21±2.32),and the practical skills score is(88.01±3.16),which is also higher than the control group's(81.05±4.12),(all P<0.01).The results of the questionnaire survey showed that the trainees in the experimental group scored significantly higher on their teaching methods to improve learning efficiency than those in the control group[(3.75±0.62)vs.(2.89±0.53)].The scores of skill for radiotherapy target delineation in experiment group were also higher than those of the control group[(4.03±0.56)vs.(3.53±0.67)],and the differences were statistically significant(all P<0.05).Conclusions Three-dimensional reconstruction digital model combined with PBL method in the training of tumor radiotherapy target delineation significantly improves the trainees'clinical practice skill through enhancement of the learning outcomes.
