摘要： 在大学本科基础课程的教学中，将基础知识与科学研究适当结合，有助于激发学生的学习积极性，并能够在学生脑海中埋下一些科学研究的种子，对学生的学术发展与国家的人才培养战略具有重要意义。在材料专业基础课无机化学“沉淀溶解平衡”章节的教学中，我们采用了文献阅读、教师引导、学生分组自学讨论、课堂讨论汇报等教学环节，将“溶度积规则”用于前沿有机半导体材料——“电荷转移共晶”沉淀析出过程的分析，从而丰富了教学内容，并扩展了溶度积规则在实际应用中的物质范畴。这样的教学设计不仅拓宽了学生对“溶度积规则”的理解，也使学生对科学研究有了初步的认识，同时培养了他们的自学能力、英语文献阅读能力、问题分析能力以及语言表达能力。

Abstract: In undergraduate foundational courses, effectively integrating basic knowledge with cutting-edge scientific research can increase students’ learning enthusiasm and ignite a sense of scientific inquiry. This approach is highly valuable for students’ academic development and aligns with talent cultivation strategic. When teaching the topic of “Precipitation-Dissolution Equilibrium” in the core Inorganic Chemistry course for materials science majors, we implemented methods such as designated literature, guided instruction, group discussions, and student-led presentations. The “Solubility Product Rule” was applied to analyze the precipitation process of “Charge Transfer Co-crystals,” a novel class of organic semiconductor materials, broadening the scope of teaching content and extending its applications. This approach not only deepens students’ understanding of the “Solubility Product Rule” but also introduces them to scientific research practices. Additionally, it strengthens their self-directed learning, English reading, problem-solving, and communication skills.

Key words: Precipitation-dissolution equilibrium, Teaching reform, Precipitation, Teaching optimization
