物理大观念导向的真实情境下的高中物理实验探究——以超重和失重为例

High School Physics Experimentation Guided by Big Ideas in Physics within Authentic Contexts—A Case Study on Overweight and Weightlessness

摘要: 研究基于“双新”的课程背景，利用文献研究法，梳理了物理观念、大观念等知识概念，以“超重与失重”章节为例，开展了基于物理大观念及真实情境的实验教学探究。通过创设真实情境，引导学生运用Phyphox工具创新课本实验，探究超重和失重过程中加速度的变化，旨在提升学生对物理概念的深入理解与应用能力，培养学生物理大观念。研究认为，物理大观念导向的真实情境下的实验教学，能有效激发学生学习兴趣，促进其科学思维和问题解决能力的提高。

Abstract: Against the backdrop of China’s “Double New” curriculum reform (new curriculum standards and new textbooks), this study employs literature analysis to clarify conceptual foundations such as “physics concepts” and “big ideas”. Taking the chapter “Overweight and Weightlessness” as an exemplar, we conducted an experimental teaching investigation guided by big ideas in physics within authentic contexts. By designing real-world scenarios, students were guided to innovate textbook experiments using Phyphox tools, exploring acceleration changes during overweight and weightlessness phenomena. This approach aims to deepen students’ conceptual understanding and application skills while cultivating their big ideas in physics. Findings indicate that authentic context-based experimentation guided by big ideas effectively enhances learning motivation and advances scientific thinking and problem-solving abilities.
