跨学科数学教学实践——基于猪肉解冻时间的数学建模研究

Interdisciplinary Mathematics Teaching Practice—Mathematical Modeling Based on Pork Thawing Time

摘要: 本文基于《义务教育课程方案(2022年版)》及高中数学课程标准，探讨跨学科数学教学实践。强调跨学科学习是对分科教学的拓展，需实现教、学、评一体。以探究猪肉常温解冻时间为例，阐述数学建模过程：提炼问题，控制变量收集温度数据，依据物理定律和散点图选指数函数建模，优化模型，分析模型缺点并检验。该案例体现数学与物理融合，展现跨学科教学在培养学生应用数学解决实际问题能力的价值。

Abstract: This paper explores interdisciplinary mathematics teaching practice based on the Compulsory Education Curriculum Plan (2022 Edition) and high school mathematics curriculum standards. It emphasizes that interdisciplinary learning extends subject-based teaching and requires the integration of teaching, learning, and assessment. Taking the exploration of the optimal thawing time of pork at room temperature as an example, the mathematical modeling process is elaborated: refining problems, controlling variables to collect temperature data, selecting exponential functions for modeling based on physical laws and scatter plots, optimizing the model, and analyzing and testing model drawbacks. This case reflects the integration of mathematics and physics, demonstrating the value of interdisciplinary teaching in cultivating students’ ability to apply mathematics to solve practical problems.
