摘要(Abstract)：

针对量纲分析教学中存在的重代数运算、轻物理机制以及由果溯因式的公式验证等现状,本文提出了物理机制主导、问题导向的教学重构方案。引入与量纲分析数学原理相同的化学方程式配平作为认知脚手架,借鉴其原理主导配平的思维范式,重构了涉及量选取与单位制确定的物理逻辑。在涉及量选取环节,界定了普适常量的机制转换作用,构建了基于物理规律的选取流程;在单位制确定环节,类比化学原子团与离子反应概念,挖掘量纲的物理独立性内涵,提出了量纲独立化与冗余删除操作。通过4个典型案例的对比分析,表明了物理机制主导方案在还原物理图景、提升分析效力及简化数学运算方面的优势。该教学重构旨在引导学生从机械地配平回归对物理本质的探究,有助于提升科学思维与模型建构素养。
