摘要： 透射电子显微镜作为材料科学、生命科学等领域的重要表征工具，其精密复杂的操作流程要求操作者兼具扎实的理论知识与娴熟的实验技能。针对现行培训体系中存在的知识点分散、学生实践参与度低等问题，本研究将问题导向学习(PBL)模式融入透射电镜培训体系，通过引入真实科研问题情境，促使学习者在解决真实科学问题的过程中深入理解电镜知识，同步提升电镜操作和分析能力。通过理论分析与案例设计，验证了PBL模式在提升学习者自主探究能力等方面的有效性，为大型精密仪器的培训提供创新思路。

Abstract: As a crucial characterization tool in materials science and life sciences, the transmission electron microscope (TEM) requires operators to possess both comprehensive theoretical knowledge and proficient operational skills. Addressing current training limitations such as fragmented knowledge delivery and limited student engagement in practical applications, this study incorporates the problem-based learning (PBL) approach into TEM training. By implementing authentic research scenarios, the PBL model facilitates deeper understanding of TEM principles while simultaneously enhancing operational and analytical competencies as learners solve real scientific problems. Theoretical analysis and case studies demonstrate the effectiveness of PBL in fostering independent inquiry skills, offering innovative perspectives for training on sophisticated analytical instrumentation.
