基于PBL的高中数学建模教学探究——以“管理红绿灯最佳转换时间”为例
Research on High School Mathematical Modeling Teaching Based on PBL—Taking “Managing the Optimal Change Time of Traffic Lights” as an Example

数学建模是数学学科核心素养的重要内容，而PBL是一种有效的教学方法，应用于数学建模能实现教学优化。为此，本文将PBL教学法与高中数学建模教学相结合并分析其应用可行性，进行“管理红绿灯最佳转换时间”为主题的高中数学建模教学设计。
Mathematical modeling is an important part of the core literacy of mathematics subject, and PBL is an effective teaching method, which can realize teaching optimization when applied to mathematical modeling. Therefore, this paper combines PBL teaching method with high school mathematical modeling teaching and analyzes the feasibility of its application, and carries out the design of high school mathematical modeling teaching with the theme of “managing the optimal traffic light transition time”.
