[1]刘祖希,宋书华.代数推理视角的初中数学估算教学研究与建议——兼谈《义务教育数学课程标准(2022年版)》的一个重要变化[J].中学数学杂志,2025,(04):16-20.
文章目录：
  • 1 问题提出
  • 2 研究概述
  • 3 案例剖析
  •     3.1 估近似值，以简驭繁
  •     3.2 估算中值，比较大小
  •     3.3 估计算法，优化算程
  •     3.4 以算估形，以形估算
  •     3.5 估计范围，感悟变化
  • 4 教学建议
  •     4.1 加强情境设置，帮助学生体会估算的价值
  •     4.2 加强推理训练，帮助学生理解估算的本质
  •     4.3 加强运算沟通，帮助学生完善运算能力结构
许多研究者开展了实践与思考，但鲜有人关注估算对代数推理的促进作用。随着新课标的实施，代数推理、估算教学引来了新的契机。我们可以学习这篇文章中，将每一个具有两点的陈述句首先放在每一个论点的第一句话的写法。再次感谢刘老师和宋老师的大作。
