发帖数: 22634 | 5 俺说句大实话。。。这里面只有 New Math 和 Traditional Math 是
正确的道路和方向。。。其他的都是因为数学老师师资问题，执行不下去，
然后教育部门里的数学家和政治家两者折中出来的垃圾。。。典型的例子
就是 New-new-math，说白了把 traditional math 和 new math
平行教就完事了，如果中小学师资过关。
俺现在个人的看法：
（1）New Math 和 Traditional Math 要平行教。因为 New Math
主要是电算用的，Traditional Math 是肉算用的。其实 99% 的小学
毕业生，将来一辈子也就只能是肉算。（按计算器本身不能算“电算”，
那个叫“不算”，设计计算器才是“电算”。）所以取消 Traditional
Math 不可取。
具体而言，俺觉得，二年级以前可能是以 Traditional Math 为主，
二年级以后逐步加入 New Math，四年级应该建立起集合论和数论之间
关系的概念。
当然，跟娃说不要用 New / Traditional 这种词。我觉得用 Ancient

是专有名词，即所谓新数学
1950s-1960s
从美国经几个法国大数学家在美国开始倡导，不仅在美国大行其道，西欧亦步亦趋。
新数学彻底改变传统数学，无论从内容，从教学法，还是考试选拔。
从 Kindergarten 开始学集合论，基本上取消传统的殴氏几何。
关键词：SMSG，后被戏称为some math,some garbage
New math是彻底失败，60年代后期被取消。
Reform math：
从1970s开始持续到现在
因为new math 彻底失败，1970年代美国开始提出back-to-basics的口号。
Reform math 又被成为 new-new math，以everyday math系列为典型。
Reform math 把大部分的集合论从小学数学当中去掉，但新数学的残余阴魂不散。所以
，理论不见了，离散数学的许多内容被强行加入到从Kindergarten自始的数学教育当中。
Reform math的特点是，强调推翻传统数学的学习方法，在kindergarten开始就开始使

1. Math Olympiad 到底是不是中国的奥数？ 学校专门有选拔，组织team, 似乎美国的

2. Math Olympiad是不是课外活动？孩子除了做题以外, 还做什么？家长需要很帮忙吗

6. Math Circle 感觉是高大上, 是不是除了数学天才，就免了？
谢谢啦！ |

So here is the question：Now... 阅读全帖 |
