初中数学新教材教学框架讨论1
22课标数学教材共出版11个版本：人教版、北师大版/鲁教版、华师大版、沪教版、浙教版、湘教版、冀教版、北京版、沪科版、苏科版、青岛版。
华师大版
（1）模块均分，代数几何每学期基本2章（如果5,6章节合并就更和谐），概率统计后4学期1章
（2）代数：各章节相对独立，每学期前后关联不大，如“数的开方”和“整除的乘除”、“分式”和“函数及其图像”；“数的开方”前置，便于“勾股定理”学习，但也导致“二次根式”放入九年级、偏晚
（3）几何：模块内容相对集中，七年级以感受为主，推理从八年级全等三角形开始
（4）设置“实践与探索”、“铺设地面”等内容作为章节内实践活动
浙教版
（1）开篇直接从有理数扩展到实数；
（2）模块章节连接相对集中，如“整式乘除”、“因式分解”到“分式”，三角形到特殊三角形，平行四边形到特殊平行四边形；跨学期上也注重连续性，如七上最后1章“图形的初步知识”到七下第1章“相交线与平行线”
（3）概率与统计内容穿插在几何和代数之间，做好缓冲作用；按照统计（收集、整理、分析）、概率进行分别编排
（4）将图形的变换放入相关图形的认识中
（5）“反比例函数”挪到最后1章，似乎也不影响之前的教学连贯性
苏科版
（1）保留“数学与我们同行”、“走进几何世界”、“定义命题证明”三个章节单独说理
（2）代数章节拆得较细，如“幂的运算”、“整式乘法”，且分布很散，与几何、概率章节穿插、不连贯；
（3）几何内容相对集中，相关内容集中在一个章节进行处理，如“三角形”、“四边形”，但章节前后不连贯
（4）概率与统计分4个章节进行处理，且分别2章节的处理也很碎
（5）编排处理可能考虑了代数和几何联系上，“实数的初步认识”放在“勾股定理”前，“平面直角坐标系”放在“一次函数”前
注：仅对框架进行初步解析，尽请批评指正
