A Study on the Strategy of Refining Big Concepts in Physics Based on Core Literacy—Taking “Mechanical Energy and Its Law of Conservation” as an Example

文章基于核心素养，研究高中物理大概念提炼策略。本文首先通过文献研究与理论分析，界定了广义大概念，并论证了核心素养是大概念提炼的立足点。基于理论，文章提出综合运用多种方法提炼大概念群，构建“大概念网络”，并绘制层级图归纳核心大概念的两步提炼法。最后文章以《机械能及其守恒定律》为例，阐述了大概念提炼策略的应用，为中学物理大概念教学提供创新参考。Based on the core literacy, the article studies the strategy of refining big concepts in high school physics. Firstly, this article defines the broad concept through literature research and theoretical analysis, and argues that core literacy is the basis for refining big concepts. Based on the theory, the article proposes a two-step refining method that integrates multiple methods to refine the big concepts, constructs a “big concept network”, and draws a hierarchical diagram to summarize the core big concepts. Finally, the article takes “Mechanical Energy and Its Law of Conservation” as an example to illustrate the application of the big concept refining strategy, which provides an innovative reference for the teaching of big concepts in secondary school physics.
