摘　　要：目的评价肿瘤放疗剂量测量中"任务"式教学对培养学生独立实践能力的可行性。方法将21名放疗剂量测量专业的本科学生随机分成实验组(11人)和对照组(10人)。实验组采用以自主学习、思考和自主设计为主的"任务"式教学,对照组采用以教师指导为主的传统教学。通过加速器电子束吸收剂量的测量案例进行学生实践考核。并采用客观而全面的评分标准对两组学生的实践能力进行评分和比较。结果实验组各实践步骤评分和总分均高于对照组(P<0.05),其中,两组总分的平均值分别为(90.18±1.97)分和(83.70±3.68)分。结论"任务"式教学可提高学生独立完成放疗剂量测量的能力。Objective To evaluate the feasibility of the"task-based"teaching mode in dose measurement of tumor radiotherapy to develop the independent practical ability of students.Methods Twenty-one undergraduate students majoring in radiotherapy dosimetry were randomly divided into experimental group(n=11)and control group(n=10).The"task-based"teaching mode based on independent learning,thinking and designing was used in the experimental group,while the traditional teaching mode based on the guidance of teachers was applied in the control group.Then the practical examination of students was carried out through the case of measuring the absorbed dose of accelerator electron beam.The practical ability of the two groups of students was scored and compared by the objective and comprehensive scoring criteria.Results The scores of each practical step and total score in the experimental group were higher than those in the control group(P<0.05).The average total scores of the two groups were(90.18±1.97)and(83.70±3.68),respectively.Conclusion The"task-based"practice teaching mode can improve students'ability of completing radiotherapy dose measurement independently.
