问题驱动式教学法,培养数学核心素养——以“三角函数的诱导公式”为例

Problem-Driven Teaching Method to Cultivate Core Literacy in Mathematics—Taking “Induction Formulas for Trigonometric Functions” as an Example

学科核心素养既是课程标准的集中体现,也是实现课程目标的基础。在高中阶段的数学教学课堂上,学生自主探究的能力被忽视,影响着学生对数学知识的掌握、思维的发展和数学核心素养的培养。文章以“三角函数的诱导公式”为例,采用问题驱动式教学法,通过问题链引领学生经历三角函数诱导公式的推导过程,培养学生逻辑推理、数学抽象、直观想象的数学核心素养。The core literacy of the discipline is not only the concentrated embodiment of the curriculum standards, but also the basis for achieving the curriculum goals. In the high school mathematics classroom, students’ ability to explore independently is neglected, which affects students’ mastery of mathematical knowledge, the development of thinking and the cultivation of mathematical core literacy. Taking the “induction formula of trigonometric functions” as an example, this paper adopts the problem-driven teaching method to lead students through the derivation process of trigonometric function induction formula through the problem chain, and cultivates students’ mathematical core literacy of logical reasoning, mathematical abstraction, and intuitive imagination.
