Abstract

This study explored the use of transmission electron microscopy (TEM) in undergraduate and postgraduate biology laboratory teaching and research training. Traditional TEM courses had limited experiments, rigid teaching methods, and weak links to current research. To address this, instructional content was improved, teaching methods diversified, research activities included, and assessments updated. Students completed the full TEM workflow, including sample preparation, instrument operation, imaging, and data analysis. This hands-on experience strengthened understanding of TEM principles, practical skills, and data interpretation. After the reform, students showed higher motivation, deeper comprehension, and better performance. The findings indicate that a structured TEM curriculum with integrated research activities enhances experimental competence and supports the development of research-focused biological talent. This approach provides a practical model for high-quality laboratory education.
