In response to the teaching requirements under the new situation of medical education reform, the Department of General Surgery of the First Affiliated Hospital of Harbin Medical University has actively carried out the SPOC (small private online course). Through special seminars, online platform exchanges and skill operation exercises, students can accurately grasp the learning focus and learn the subject knowledge efficiently, which has realized the teaching goals of situational, problematic, multi-dimensional and task-based teaching and learning. It is a new type of online and offline interactive teaching model, which is worth further promotion.
