摘要： 本文概述了医用化学课程中“溶液的渗透压”章节的教学设计与思考。该章节涉及到渗透现象、渗透浓度、溶液渗透压的计算以及渗透压在医学上的应用等内容。渗透浓度和渗透压的计算是大部分学生较难掌握的部分。因此在教学设计中，以问题为导向，结合生活中的现象和案例，通过“创设问题情境-实验探究-计算推导-知识迁移与应用-知识拓展延伸-课程思政融入”将知识点串联起来。将计算实例与医学案例贯穿到整个教学中，通过问题导向的教学方式能够提高学生的学习兴趣，使学生在课堂教学中就能及时掌握本章的知识点与内容，达到教学目标。

Abstract: This paper presents an overview of the teaching design and considerations for the chapter on “osmotic pressure of solutions” in medical chemistry courses. The chapter covers topics such as osmotic phenomena, osmotic concentration, the calculation of solution osmotic pressure, and its applications in medicine. The calculation of osmotic concentration and osmotic pressure presents significant challenges for most students. To address this, the teaching design is centered on a problem-based approach, incorporating real-life phenomena and case studies. The instructional sequence includes creating problem scenarios, experimental exploration, computational derivation, knowledge transfer and application, knowledge extension, and integrating ideological and political education. By weaving computational examples and medical case studies throughout the course, the problem-oriented teaching approach enhances student engagement and helps them grasp the key concepts and content of the chapter during classroom instruction, ultimately achieving the teaching objectives.
