基于核心素养的初中数学大单元教学设计策略——以“一次函数”为例
Middle School Mathematics Teaching Design Strategy Based on Core Accomplishment—Taking the “Linear Function” as an Example

在当前教育改革的大环境下，中学数学核心素养在课堂教学中的落实显得尤为重要。大单元教学相比传统课时教学更有利于学生从整体上掌握知识，培养核心素养。本文结合初中数学的内容制定了大单元教学设计的一般步骤，然后选取“一次函数”为大单元主题进行了教学设计分析，并以“一次函数与方程、不等式”为例设计教学过程，为教师的教学实践提供参考。
In the current environment of educational reform, the implementation of core mathematical literacy in middle school mathematics is particularly important in classroom teaching. Compared to traditional classroom teaching, large unit teaching is more conducive to students mastering knowledge as a whole and cultivating core competencies. In this paper, the general steps of large unit teaching design are formulated based on the content of junior middle school mathematics, and then the teaching design is analyzed by selecting “Linear function” as the theme of large unit, and the teaching process is designed by taking “Linear function, equation and inequality” as an example to provide reference for teachers’ teaching practice.
