基于PBL的高中数学情境教学模式探究——以“直线与平面垂直”为例

Senior High School Mathematics Situational Teaching Mode Based on PBL—A Case Study of “A Straight Line Perpendicular to a Plane”

摘要: 在高中数学课程改革背景下，情境化教学成为落实学科育人目标的重要路径。本文以提升高中数学核心素养为根本宗旨，针对传统教学模式中知识与应用脱节的困境，对基于PBL的高中数学情境教学模式进行了深入探究。研究在梳理PBL与情境教学理论的基础上，明确构建原则、目标和流程。并且以“直线与平面垂直”为例设计以“校园旗杆垂直度检验”为驱动项目的完整教学案例。本研究为高中数学课堂教学改革提供了有益的参考与实践范式。

Abstract: In the context of the ongoing reform in senior high school mathematics curriculum, contextualized teaching has emerged as a vital approach to achieving educational goals through disciplinary instruction. With the primary objective of enhancing students’ core mathematical competencies, this study addresses the disconnection between theoretical knowledge and practical application in traditional teaching models. It conducts an in-depth exploration of a Problem-Based Learning (PBL) contextual teaching framework for senior high school mathematics. Building on a systematic review of PBL and contextual teaching theories, the research clarifies the construction principles, instructional objectives, and operational procedures of this teaching model. Furthermore, taking “a straight line perpendicular to a plane” as an illustrative example, it designs a complete teaching case centered on the driving project of “inspecting the vertical alignment of campus flagpoles”. This study offers valuable insights and a practical paradigm for the reform of mathematics classroom teaching in senior high schools.
