核心素养导向下高中数学项目式学习的教学设计与实践研究 ——以“三角函数的实际应用”为例

Teaching Design and Practice Research of Project Based Learning in High School Mathematics under the Guidance of Core Literacy—Taking “Practical Application of Trigonometric Functions” as anExample

摘要: 当前基础教育课程改革的核心在于促进学生核心素养的发展。数学核心素养作为学科育人价值的集中体现，其有效培养亟需突破传统教学中侧重知识传授与解题训练的局限。项目式学习凭借其情境真实性、任务驱动性和探究过程性，为整合发展数学抽象、逻辑推理、数学建模等核心素养提供了重要的实践路径。本研究聚焦高中数学，以“三角函数的实际应用”为具体载体，系统探索核心素养导向下的项目式教学设计与实践，旨在为深化素养落地提供可操作的案例参考和理论支撑。

Abstract: The core of current basic education curriculum reform is to promote the development of students’ core competencies. As a concentrated manifestation of the educational value of the subject, the effective cultivation of mathematical core literacy urgently needs to break through the limitations of traditional teaching that focuses on knowledge transmission and problem-solving training. Project Based Learning (PBL) provides an important practical path for integrating and developing core competencies such as mathematical abstraction, logical reasoning, and mathematical modeling through its situational authenticity, task-driven nature, and exploratory process. This study focuses on high school mathematics, using the practical application of trigonometric functions as a specific carrier to systematically explore project-based teaching design and practice under the guidance of core competencies, aiming to provide actionable case references and theoretical support for deepening the implementation of competencies.
