支架式教学模式下基于数学建模素养培养的高中数学教学设计——以“解三角形的应用”为例

The Teaching Design of High School Mathematics Based on the Cultivation of Mathematical Modeling Literacy in the Scaffolded Teaching Mode—Taking “Application of Triangle Solution” as an Example

摘要: 支架式教学模式为学习者提供框架，将复杂问题逐步简单化，同时培养学生在学习中的自主性，以达到知识建构的目的。数学学习与应用在数学学科核心素养中的地位逐渐加重，数学建模作为其中之一，搭建了理论与实践的桥梁。本文以数学建模思想为基础，结合支架式教学，以解三角形的应用教学为例，探讨和研究建构主义学习理论下的支架式教学设计。

Abstract: The scaffolded teaching model provides learners with a framework to gradually simplify complex problems, and at the same time cultivates students’ autonomy in learning, so as to achieve the purpose of knowledge construction. The learning and application of mathematics play an increasingly important role in the core literacy of mathematics, and mathematical modeling, as one of them, builds a bridge between theory and practice. Based on the idea of mathematical modeling, combined with scaffolded teaching, this paper takes the applied teaching of solving triangles as an example to discuss and study the scaffolded teaching design under the constructivist learning theory.
