基于问题导向学习的透射电镜培训模式探索

doi:10.12461/PKU.DXHX202505034

Abstract

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.

Key words: Problem-based Learning, Transmission electron microscope, Instrumentation training, Independent inquiry skills
