摘要本研究旨在突破传统静态病例设计的局限性，构建基于大语言模型的"动态提示词模型"，并探究其在儿科医学教育中的应用效果。该模型涵盖疾病病程推进信息(前驱期、急性期、恢复期)、完整的临床决策链条(问诊、查体、辅助检查、诊断、治疗)和由浅入深的认知目标(记忆、理解、应用、分析、评价)。疾病清单包括儿科常见病和少见病两大类。选取中国医科大学儿科医学专业四年级45名学生作为研究对象，开展为期4周的学习任务。研究结果表明，动态病例学习后，虚拟病例成绩从(75.31±15.21)分提高至(82.22±11.43)分；批判性思维能力从(102.67±10.93)分提高至(110.13±12.61)分，其中系统分析能力从(42.85±3.91)分提高至(45.13±4.61)分，知识探索意愿从(31.55±3.74)分提高至(36.32±5.11)分，其差异均具有统计学意义(均 P<0.05)。不同病例的真实感评分较高(均>4分)，难度评分分布具有一定合理性。在体验评价中，促进学习维度评分最高[(4.02±0.47)分]。"动态提示词模型"有效提升了医学生的临床思维能力和批判性思维能力，为儿科医学教育提供了一种高效、创新的教学工具。

abstractsThis study aims to break through the limitations of traditional static case design by constructing a ″dynamic prompt model″ based on large language models and exploring its application and effectiveness in pediatric medical education. The model encompasses disease course progression information (prodromal, acute, and recovery phases), a complete clinical decision-making chain (history taking, physical examination, auxiliary investigations, diagnosis, and treatment), and progressively advanced cognitive objectives (remembering, understanding, applying, analyzing, and evaluating). The disease list includes two categories: common pediatric diseases and rare diseases. The study selected 45 fourth-year pediatric medical students from China Medical University as research participants to conduct a 4-week learning program. The results indicate that after learning with dynamic cases, the virtual case scores significantly increased from (75.31±15.21) to (82.22±11.43). Critical thinking ability improved from (102.67±10.93) to (110.13±12.61), with system analysis skills rising from (42.85±3.91) to (45.13±4.61) and knowledge exploration willingness increasing from (31.55±3.74) to (36.32±5.11), all P<0.05. The realism scores of different cases were relatively high (all>4), and the difficulty ratings were reasonably distributed. In the experience evaluation, the ″enhancing learning″ dimension scored the highest (4.02±0.47). Therefore, the ″dynamic prompt model″ effectively improved medical students′ clinical thinking and critical thinking abilities, providing an efficient and innovative tool for pediatric medical education.
