目的 探讨吉布斯反思循环对ICU护理实习生评判性思维能力与自我导向学习能力的干预效果。 方法 采用便利抽样法选取2021年7月—2022年9月在遵义医科大学附属医院ICU实习的150名护理本科生为研究对象，按照入科时间分成试验组（n=75）与对照组（n=75）。对照组采用传统带教模式，试验组在此基础上采取吉布斯反思循环进行临床实践教学干预，为期4周，实习生根据吉布斯反思循环要求完成反思日记，汇报与分享反思结果，整合反思结论。比较干预前后两组的评判性思维能力与自我导向学习能力。 结果 干预后试验组的评判性思维能力得分为（300.33±16.71），对照组为（291.49±11.69），两组比较差异有统计学意义（t=3.754，P<0.001）；干预后试验组自我导向学习能力得分为（151.69±21.95），对照组为（136.99±27.56），两组比较差异有统计学意义（t=3.614，P<0.001）。 结论 吉布斯反思循环能够在一定程度上提高ICU护理实习生的评判性思维能力及自我导向学习能力。

Objective To explore the effect of Gibbs reflective cycle on critical thinking ability and self-directed learning ability of nursing undergraduates in their internship in intensive care unit （ICU）. Methods A convenience sampling method was used with 150 nursing undergraduates who practiced in the ICU of the Affiliated Hospital of Zunyi Medical University from July 2021 to September 2022. The participants were divided into two groups with 75 students in experimental group and 75 students in control group depending on their time of admission. The control group was treated with traditional follower teaching mode，and the experimental group was treated with Gibbs intervention on this basis among four weeks. Participants completed the reflection diary according to Gibbs，reported and shared the reflection results，integrated the reflection conclusions. The scores of critical thinking ability and self-directed learning ability before and after intervention were compared between the two groups. Results After intervention，the score of critical thinking in the experimental group was（300.33±16.71），while that in the control group was（291.49±11.69）. The difference between the two groups was statistically significant（t=3.754，P<0.001）. After intervention，the score of self-directed learning ability in the experimental group was （151.69±21.95），while that in the control group was（136.99±27.56）. The difference between the two groups was statistically significant（t=3.614， P<0.001）. Conclusion Gibbs teaching method can improve the critical thinking ability and self-directed learning ability for nursing undergraduates during their clinical internship in ICU.
