Abstract The small private online course (SPOC) of Principles of Chemical Engineering for the majors of Chemistry, Material, Environment, Pharmaceutical Sciences, etc., has been constructed by the teaching team of chemical engineering in Zhejiang Normal University. We recorded 101 micro‐videos of knowledge points, which explained in detail the fluid flow, fluid transportation machinery, heat transfer as well as distillation and absorption; and briefly interpreted the operations involving particulate solids, mass transfer equipments, evaporation, extraction, and drying of solids. The SPOC course has been online and run for 2 years on Zhejiang Institutions of Higher Learning Online Open Course Sharing Platform. Our teaching practices show that the online/offline blended learning combines the students’ online self‐study through micro‐videos before class with traditional classroom, and greatly improves the learning efficiency. Meanwhile, the blended learning based on the online courses shares the high‐quality courses and will be the future trend in higher education.
