指向深度学习的高中数学支架式教学模式实践与探究——以“椭圆及其标准方程”为例
Practice and Exploration of Scaffolding Teaching Mode of Mathematics in Senior High School Oriented to Deep Learning—Taking “Ellipse and Its Standard Equation” as an Example

《普通高中数学课程标准(2017年版)》提出了以学生的发展为本，培养和提高学生核心素养的要求，同时国家要求尽快落实立德树人的根本任务，发展素质教育。在素质教育理念的指导下，高中数学教学模式发生了根本性的变化，支架式教学成为课堂教学的一种重要模式，基于此，对我国高中数学教学现状进行分析，以“椭圆及其标准方程”为例，探讨支架式教学模式对实现学生深度学习的重要意义，为数学学科核心素养落地课堂提供新思路。
The General High School Mathematics Curriculum Standard (2017 Edition) puts forward the requirements of taking the development of students as the basis and cultivating and improving the core qualities of students, and at the same time, the state requires the implementation of the fundamental task of establishing moral education as soon as possible and the development of quality education. Under the guidance of the concept of quality education, the teaching mode of high school mathematics has undergone fundamental changes, and scaffolding teaching has become an important mode of classroom teaching. Based on this, the current situation of high school mathematics teaching in China is analyzed, and “ellipse and its standard equations” is taken as an example to explore the significance of scaffolding mode of teaching in realizing the depth of student learning. Based on this, we analyze the current situation of high school mathematics teaching in China, and take “ellipse and its standard equation” as an example to discuss the importance of scaffolding teaching mode in realizing students’ deep learning, and to provide new ideas for the implementation of core literacy in the classroom of mathematics.
