Abstract The wave function is a core concept in Structural Chemistry,yet its abstract nature and mathematical complexity pose significant challenges to students' conceptual understanding.To address this issue,we have designed and implemented a novel instructional approach centered around a “cognitive logic framework of the wave function”. By utilizing the Stern-Gerlach cascade experiment to guide students in establishing the concepts of eigenstates and superposition states,deriving the state vector from the mathematical form of superposition states,and then transitioning to the wave function through graphical representations of state vector projections in different representations,this teaching design adheres to the principles of progressing “from the known to the unknown,from experimental phenomena to abstract concepts,from mathematical forms to physical images,and from the abstract to the concrete”. Throughout the process,graphical teaching of concepts and mathematics is incorporated.Teaching practice demonstrates that this new instructional design effectively enhances students' deep understanding of the origin,meaning,and application of the wave function.
