通过问题引领，引导数学探究——以“椭圆及其标准方程(第一课时)”教学为例
Guide Mathematical Exploration through Problem Guidance—Taking the Teaching of “Ellipse and Its Standard Equations (the First Lesson)” as an Example

数学问题不仅是数学活动的重要载体，还能有效激发学生的数学思维，并引导他们进行深入地数学探究。本文以椭圆及其标准方程(第一课时)为例，通过创设合理的问题情境引导学生进行数学探究，帮助学生构建新知，以此来发展学生的数学学科核心素养。
Mathematical problems are not only an important carrier of mathematical activities, but also can effectively stimulate students’ mathematical thinking and guide them to carry out in-depth mathematical exploration. This article takes ellipses and their standard equations (the first lesson) as an example to guide students to conduct mathematical exploration by creating reasonable problem situations and helping students build new knowledge, so as to develop students’ core literacy in mathematics.
