强调"procedure" 即所谓的constructive math,
意在不是通过老师去教授解道,而是要强调学生自己去摸索出数学的真意。
数学的概念,在中国(其实是模仿前苏联50年代的数学)是通过学生自己大量做题之后
逐渐地加以理解。我认为这有两个原因,其一中国数学老师自己本身就弱,况且数学也
是从西方引进的,还没有彻底融入到中华文化当中。其二,中国传统文化强调“熟读唐
诗三百首”和潜移默化。
在美国的数学课堂上,数学老师的作用跟美国现任总统一样,是个community
organizer,老师的作用是让学生高兴玩乐,学生通过各种manipulatives(即各种教学
玩具)自己去构建数学概念。
美国在历史上数学一直不强,二战之后骤然兴盛,是因为犹太人都跑来美国了。
但二战后的fields奖,许多即使美国的获奖者,大家可以去查查看,许多是东欧裔犹太
人的后代。
90年代之后这么多中国人可以拿美国大学的奖学金来美国读书工作,原因之一就是美国
的数学太差。数学差,导致所以物理化学工程类,美国人自己都作不来。所以,虽然不
喜欢中国人,但也只得忍着让多少懂点数学的中国人来了。

不过总体而言,两者结合比较好。
另外还是要加数学的课时。。。数学发展了很多年了,比以前复杂多了。
况且 modern mathematics 对小学娃,其实还是在讲故事的阶段,
应该加开课程,而不是去取代 traditional math。。。(当然,
traditional math 的刷题部分可以适当减少)。

近日,我系沈维孝教授的论文“Combinatorial rigidity for unicritical

表(2006年),另有两篇论文被接受发表。据悉,自改革开放以来,有国内学者参与的、
在Ann. Math.上正式发表的论文只有5篇,其中以国内为独立完成单位的只有两篇(含
沈维孝教授的一篇)。
在这篇与Artur Avila,Jeremy Kahn,Mikhail Lyubich合作的论文中,作者证明了非

另外,我觉得 New Math 在小学中年级执行不下去的几个坎是
(list 不全):
(1) 不严格的娃版 Axiom of Infinity => 自然数
(2) 从 token 和 pattern 的角度来娃版粗浅理解
positional notation system (place value)
(3) 娃版映射到自然数集的概念(indexing)
(4) 娃版通过加法乘法分配率环来理解娃版负数和分数的乘法
这个坎有点稍大
(4) 娃版 UPF (unique prime factorization)
(5) 无理数的出现,分数的可数性
(6) 娃版空间对称性
(7) 娃版理解和处理有关环结构
这个坎也有点稍大
(8) 娃版 decision tree

另外有关环结构。。。现代数学的晦涩环理论虽然实际用处也不大
。。。但对小学娃而言,俺觉得,建立“环”和“数(tree)”的那么
一点点味道(以及更复杂的结构图景),是给将来 complex problem
solving 打点地基。。。娃小的时候,思维没有定型,正好是探索
“play the middle like a magician” 的最佳时机。
从这个角度说,traditional math 在小学阶段最大的缺点,
就是太强调线性的思维方式。。。用俺老的说法,就是“铁棒式
思维”,或者“冰箱说明书从第一页翻到最后一页之循规蹈矩姿势
的铁棒式思维”。。。但是将来高大上一点的数学,一点都没有
“乱中取胜”的味道,都不好意思出门跟人打招呼是不是?。。。

Everyday math 我只翻了翻
但那一套玩意跟麻州这边的发现式数学什么破玩意都是一回事
用美国数学家的专有名词来解释
就是spiral 式学习模式
数学定义定理在kindergarten就开始学
越早学越好,这是他们的教学哲学
第一年学了虽然没懂也不要紧
第二年,第三年反复不停地学
这种教育哲学是suppose 现代数学的思想只有这样才能彻底贯穿下去

前苏联的数学强,因为采取的恰恰是classical education的模式
强调的是基本功、脚踏实地、步步为营的教学哲学
要知道 Moscow State Univ.的 数学系用英语可以翻为
Dept of math and mechanics
数学必须跟科学工程结合在一起。
这个恰恰是中国数学教学中差的无穷远的地方。
Hungary 的数学也非常强。Hungary的数学教学一直像前苏联看齐
当前苏联也开始跟美国同步搞新数学时,Hungary就慢了一步
因此前苏联在新数学上的弯路,Hungary就没有照搬。

但我从我实战看娃的角度看,我觉得许多 spatial thinker,即使有不错

从任何角度来看,其实教fin maths的学术难度并不高。记得以前有人说,对于一个工程

几乎所有的quant都是这么出来的。说北大教fin maths的教授刚开始学,没问题

问题是fin maths是一个实用性很强的学科,有些东西没有实地在trading desk干过,完全

I don't know which state you are in. If you want to get certified to teach
math in public schools, you'd better check the certification requireements.
For getting in the program, I do think math background is important. If you
