摘要: 本案例以解决传统Fe(OH)₃胶体电泳实验中存在的胶体废液浪费、缺乏探究性以及思政育人难融入等局限为出发点，通过发展胶溶法、引入表面带不同电荷AgI胶体制备及其带电性质自主判断环节，守正创新，赋予该实验项目以资源节约、绿色环保、富有探究性等特色。尤其重要的是，本案例通过综合采用任务驱动自主学习、翻转课堂、研讨启发等多种教学模式，将经典基础物理化学实验与提高我国数量巨大但来之不易的钢铁资源的循环利用率和改变学生对胶体带电性质的固有认识有机结合起来，在潜移默化中弘扬/培育了学生“绿色”化学理念、可持续发展责任担当、科学辩证思维素养以及创新精神等。本案例已初步推广应用于本校的胶体电泳实验教学中，教学反响热烈，达到了专业知识、技能传授与课程思政育人相济相长的教学效果；为提升传统实验的专业育人和思政育人效果提供有益借鉴。

Abstract: This experimental case aims to address the limitations of traditional Fe(OH)₃ colloid electrophoresis experiments, such as the waste of Fe(OH)₃ colloids, the lack of exploration, and the difficulty in incorporating ideological and political education. To do so, we have developed a colloidal dissolution method, introduced AgI colloids with different surface charges and designed colloid surface charge exploring assays, thus rendering this experiment with the features of resource conservation, green development, and richness of inquiry. It is particularly important that this case has integrated multiple teaching modes (e.g., task-driven self-learning, flipped classroom, and deliberative teaching) to seamlessly combine this basic experiment with the improvement of the recycling ratio of China’s steel resources and the correction to students’ inherent knowledge on the surface charges of colloids. As a result, green chemistry concept, sustainability responsibility, scientific dialectical thinking skills, and innovation spirit can be implanted into the mind of students in a nature way during this experiment. This case has been initially applied to the colloid electrophoresis experimental taught in our university, achieving excellent teaching responses and mutual promotion effect between value shaping, knowledge imparting and ability cultivation. Hopefully, this case can provide helpful reference for enhancing the effect of professional education and ideological and political education in basic experiments.
