摘要： 微电极技术发展迅速，其理论已被纳入理论课教材中，但缺乏实验教学内容。为了推动实验教学与科学前沿的高效衔接，我们设计了新型的微电极教学实验。从简便的碳纤维微电极制备入手，通过比较式学习，实现了从电极过程到性能分析的多维度知识融合。同时创新地引入试错式教学模式，有效提高学生独立探索的能力，助力人才培养。

Abstract: Despite the rapid advancement of microelectrode technology and its incorporation into theoretical chemistry textbooks, there remains a significant gap in experimental teaching materials. To bridge this gap and foster a more effective integration between experimental pedagogy and cutting-edge electrochemical research, we have developed an innovative microelectrode teaching experiment. This experiment begins with a straightforward carbon fiber microelectrode fabrication process and employs a comparative learning approach to integrate multidimensional knowledge ranging from electrode processes to performance analysis. Furthermore, we have introduced a trial-and-error teaching methodology to enhance students’ independent exploratory skills, thereby contributing to the cultivation of exceptional talents.
