本文针对本科量子力学一维无穷深势阱教学中重数学推演、轻物理图像的普遍问题，提出以“物理图像—数学形式—经典极限”三维架构重构教学.核心方法是引入经典碰撞模型建立认知桥梁.物理图像维度：模型直观展示动能势能转化守恒，阐明无穷深势阱边界来源，纠正“经典深井”认知偏差；数学形式维度：模型通过量纲分析及概率密度类比，赋予能量参数与边界条件物理实质；经典极限维度：模型通过平均概率密度、零点能对比，加深理解量子体系本质特征.实践表明，该策略在多数情况下能有效帮助学生克服认知偏差，深刻理解波函数统计诠释、能量量子化等概念，成功构建量子思维范式.

This paper addresses the prevalent issue in undergraduate quantum mechanics instruction of the onedimensional infinite square well, where mathematical derivation is prioritized over physical imagery, proposing a restructured teaching approach through a threedimensional “physical imagerymathematical formalismclassical limit” framework by introducing a classical collision model as a cognitive bridge—where the physical imagery dimension visually demonstrates kineticpotential energy conservation to clarify boundary origins and correct “classical deep well” misconceptions; the mathematical formalism dimension employs dimensional analysis and probability density analogies to imbue energy parameters and boundary conditions with physical meaning; and the classical limit dimension contrasts average probability density and zeropoint energy with classical models to reveal quantum systems’ essential characteristics, with practice confirming this strategy effectively helps students overcome cognitive biases, grasp core concepts like wave function statistical interpretation and energy quantization, and establish a quantum thinking paradigm.
