以案例为基础的学习法(CBL)在医学、商学和法学领域应用日益广泛，CBL在医学教育领域一直受到人们的关注。笔者将CBL应用在临床诊断学教学，以真实的临床场景为基础培养医学生临床实践技能和正确诊断思维，培养学生使用所学理论知识和推理能力来解决临床问题。CBL具有参与性和启发性，能有效提高医学生的分析和解决问题能力，有助于医学生的逻辑推理能力和综合诊断技能的培养并在未来的职业发展过程中灵活运用其诊断技能。CBL能有效提高学生临床诊断技能，在临床诊断学教学中取得了较好效果，值得重视和推广。

Case-based learning (CBL) is widely applied in the field of law, business and medicine education.CBL is a student-centered teaching methodology, which has been receiving attention in medical education.We applied CBL in clinical diagnostics teaching. CBL exposes students to real-world scenarios that need to be solved using their reasoning skills and existing theoretical knowledge.The participation and stimulation of CBL could effectively improve medical students′ ability to analyze and solve clinical problems, which is very important for their career development in the future. CBL helps medical students′ logical reasoning ability and the comprehensive diagnostic skills training, so that medical students could actively apply clinical reasoning skills to their diagnostic interpretative, diagnostic, and treatment skills in a scalable way. CBL improves clinical skills, and it achieves good effect in clinical diagnostics teaching. This teaching method is worth promoting.
