核心素养下的同课异构——“椭圆的标准方程”教学实践与反思

The Differentiated Teaching Followed the Core Literacy —Teaching Practice and Reflection on the “Standard Elliptic Equation”

摘要: 《普通高中数学课程标准》2017版强调培养学生的数学核心素养，教师需关注学生的长远发展，在教法上注意贴合新课改的核心理念，在教学中渗透数学思维和思想方法，切实提升学生的综合能力，以达到育人目标。以“椭圆的标准方程”一课的同课异构为例，探讨什么是核心素养下好的数学课堂。

Abstract: The 2017 edition of China’s high school mathematics curriculum standards focuses on promoting students’ core mathematical skills and their long-term development. Teachers should incorporate the core concepts of the new curriculum reform into teaching methods and integrate mathematical thinking and reasoning into lessons to improve students’ comprehensive skills and achieve educational goals. This paper discusses what is a good mathematics classroom under the core literacy by taking the isomerism of “standard equation of Ellipse” as an example.
