本文研究中学数学教学中的问题链设计。在以学生为中心的教育理念下,问题链作为有效教学策略意义重大。文章阐述了问题链的定义、特点,分析了其在激发学习兴趣、构建知识体系、契合认知发展等方面的作用,探讨了设计需遵循的原则与方法。通过教学实践案例验证了问题链的有效性,但实践中存在难以兼顾学生差异、教学节奏把控难等问题,提出了分层教学、提升教师应变能力等对策。未来应结合教育心理学优化设计,构建最佳问题链模式,提升教师教学能力,探究其应用效果及与其他教学方式的融合,为中学数学教学改革提供支撑。This paper investigates the design of problem chains in middle school mathematics teaching. Under the student-centered educational philosophy, problem chains serve as an effective teaching strategy with significant implications. The paper elaborates on the definition and characteristics of problem chains, and analyzes their roles in stimulating learning interest, constructing knowledge systems, and aligning with cognitive development, among others. It also explores the principles and methods to be followed in their design. The effectiveness of problem chains is verified through practical teaching cases, yet issues such as difficulty in accommodating student differences and controlling teaching pace arise in practice. Countermeasures such as tiered teaching and enhancing teachers’ adaptability are proposed. In the future, it is essential to optimize design by integrating educational psychology, establish optimal problem chain models for different knowledge types, enhance teachers’ teaching capabilities, and explore the application effects and integration with other teaching methods to support the reform of middle school mathematics teaching.
