The Application of Scaffolding Instruction in Senior High School Mathematics Teaching—Taking “Binomial Distribution” in the People’s Education Edition A Textbook as an Example

支架式教学是当代高中数学课堂教学的一种重要模式，支架式教学以搭建支架的方式引领学生认知知识、领悟知识、掌握知识。基于此，文章简单阐述支架式教学在高中数学教学中的教学策略，即灵活搭建支架；利用支架衍生问题；学生自主探究；加强巩固训练；重视成果评价。并以“二项分布”内容为例，探讨支架式教学在教学过程中的具体应用和注意事项。Scaffolding instruction is an important mode in contemporary senior high school mathematics classroom teaching. It guides students to recognize, comprehend and master knowledge by means of constructing scaffolds. Based on this, this article briefly expounds the teaching strategies of scaffolding instruction in senior high school mathematics teaching, namely flexibly constructing scaffolds, deriving problems by using scaffolds, enabling students to conduct independent inquiry, strengthening consolidation training, and attaching importance to achievement evaluation. Taking the content of “binomial distribution” as an example, this article explores the specific application of scaffolding instruction in the teaching process and the matters needing attention during the teaching process.
