为促进学生深度学习，提升物理化学课程教学质量，以表面化学中“弯曲表面的附加压力和蒸气压”的教学为例，从学生实际出发，应用DOK (Depth of Knowledg，知识深度)理论划分教学内容等级，设计不同课堂活动和小组任务，从力和能量两个角度深化逻辑主线，体现学科融合，培养高阶思维。对于教学难点Kelvin方程，以表现性任务体现生活和生产中的实际应用，激发兴趣。以小组讨论话题层层递进，从力对于化学势的影响出发，将Kelvin方程从单组分系统推广到多组分溶液和多组分化学反应系统，体现热力学的多元应用，意义建构。通过课前SPOC (Small Private Online Course，小规模在线课程)任务清单，课上雨课堂翻转讨论，课后公众号展示拓展，开展混合式教学。经过教学实践，结合问卷调查和学生产出，发现基于深度学习的DOK教学，不仅能帮助学生发展各项高阶能力，而且学习主动性和实践创新能力都得到有效提高。
