可是如果只是省FICA TAX的话, 那5000 * 7.65% = $382.5. 而如果CLAIM CHILDCARE
EXPENSE CREDIT的话, 即使工资再高也应该拿到3000*0.2=$600
这样还是FSA不省钱阿 |

t*******r 发帖数: 22634 | 2 我的意思是学琴要学音乐,学成琴匠最最没意思。特别是 mp3 如此普及的
今天,谁需要一个琴匠给你 replay 乐谱啊?过去那是码工们没搞出 mp3,
没办法。。。
实际上,这年头,码工们对音乐性的普及做了巨大贡献。对于手头有 mp3,
也喜欢听音乐的码工而言,如果还被人说成音盲,我看是谁盲还真不好说。
如果小孩弹一首比如 row row row your boat 之类的脍炙人口的乐曲,
码工父母也听过这首曲子,然后父母还听不出来小孩弹错了。。。那可能是
有点那个啥。。。
但是弹一首父母们听也没听过的十八世纪的啥复杂破曲子。。。其实我也可

t*******r 发帖数: 22634 | 4 “更重要的一方面是养成思维和分析能力” —— 这点你说的没错。
但是你下面说的,“如何通过对证明若干引理 。。。 数学归纳法等等” ——
似乎没有强调 “global picture” 的重要性。
其实我觉得中小学教师思维上容易出现的偏差是,中小学教师通常都在 work
on 对他们自己已知的问题。教授过程,对他们自己更多的是 replay the
known,而不是 explore the unknown。就像在固定的线路上教开车,
久而久之,就会越来越强调方向盘/刹车/信号灯/路标,却忘了强调如何看地图 /
应付不同海拔气候条件 / 不同能见度 / 如何使用 GPS / 汽车机械故障 。。。
不少中学教师,做未知的竞赛题,即使在不限制时间的条件下(考虑思维的速度
受到年龄的影响),也不一定能做过学校里学科竞赛的种子选手,俺认为部分是
上述原因。。。 |

25 Ways to Talk So Children Will Listen
A major part of discipline is learning how to talk with children. The way
you talk to your child teaches him how to talk to others. Here are some
talking tips we have learned with our children:
1. Connect Before You Direct
Before giving your child directions, squat to your child's eye level and
engage your child in eye-to-eye contact to get his attention. Teach him how

驱动,关键是 shutdown 感性。
比如看些书/教育节目,不仅是理解,而且是通过书/教育感受到毒品的后果,
培养厌恶毒品的情绪。重复 replay 该 pattern 到一定程度,从而
shutdown 对此的好奇心之类的人之本能,才能不去碰。说白了,就是
自己给自己洗脑。。。
另外独立价值观,anti-verbal-bully,不人云亦云等等的综合素质,

t*******r 发帖数: 22634 | 9 我觉得不排除有 "teacher-introduced-false-solution-path" 的可能。
现实的说, 很多 teacher 并不是 excellent problem solver, 他们往往是 excellent

这很多时候是好事, 但在对待思维训练目的的娃版 jigsaw puzzle, 他们可能反而会倾
向于把原本是 inherently non-routine problem, 试图把其转化为 routine problem,
使得娃能尽快掌握 solve 此类 problem 的技巧。。。但娃也可能学成一个 good

Scientists/Engineers 正相反. They are excellent people to confuse everyone
else, and frequently be the most poor presenter in this planet.... 阅读全帖 |

t*******r 发帖数: 22634 | 10 俺觉得,如果不是单纯为了考试的话,practice 有三个层次:
1. practice "replay the procedure / routine"
2. practice "from known to known (efficiently)"
3. practice "from known to unknown"
所谓刷题走火入魔,指的就是不强调应才施教,也不考虑世易时移,以及娃的成长变化
,钻在上面第二个层次的 practice 出不来了。。。后果可能是杀兴趣,或者杀创造心
,或者废材。。。 |

也就是说,虽然我们都知道数学史不是这样的,但 "let's say, let's

t*******r 发帖数: 22634 | 13 如果不是有人直接告诉答案,而是一步一步从少到多给 hints,
哪个凑结果的方法容易自然 induce 出来?
或者你用这个去凑一下(当然你也可以看着公式凑就是了):
1^5 + 2^5 + 3^5 + 4^5 + .... + N^5 ?
其实俺觉得很多所谓 “巧妙” 的凑法,其实可能从教育角度
看是有问题的。。。因为虽然数学教学虽然不是 re-invent
the wheel,但数学教学实际上是在 replay the invention
of the wheel。。。而实际上就是,历史上前几个证明/导出
常常是相对而言繁琐的。。。
俺不是数学老师,俺也不知道咋教娃。。。不过俺认为如果
俺自己不能借助 minimal 的 hint 给 induce 出来的方法,
我就悠着点。。。
所以其实俺前面那个导出,俺是先不看现成结果,自己尝试
导出,在娃面前 fail 了两次,最后导出以后,才跟网上的
方法比较。。。因为我觉得作为普通人,这样搞对普通娃比较

t******l 发帖数: 10908 | 18 我觉得祖国数学的优势方面,还是在于代数及代数之后。
个人觉得祖国数学这并不是题海的优势,而是题目的答案和解题步骤是标准的、正确的
。这样而来对师资培训要求不高,教师只要能按既定方针 replay 几遍,然后盯着娃娃
做 workbook,就行了。当然学生的修行就要靠自身了。
美帝这边的教育理念高大上的多,但实践上的 implementation 是个问题,特别是对师
资的要求。 |

t******l 发帖数: 10908 | 19 个人觉得,从竖式乘除法,推广到所有的 standard algorithm、以及见过的题型,
需要练习多少,练习到多熟练,我觉得都要看自家情况以及对娃的预测,按各家娃不
同的目标,而驱动。
如果走数学竞赛 track,哪怕是 AMC8,那 standard algorithm 以及见过的题型,
一定得熟练。
Quantified 举例,AMC8 的 1 - 15 题,如果能做到每题一分钟,那么总共 15
分钟,还留下 25 分钟做后面的 16 -25 题有难度的题。但如果每题花了两分钟,
30 分钟就去掉了,再卡壳一两题脑筋转弯想一想,基本 16 题以后根本也没机会
做了。
不要取笑上面这个,大部分普通娃就是搞成两分钟多才做一题。后面的题连个机会
都不会有。
但如果考虑普通娃高中能跟上进度不 decay,那我个人觉得瓶颈,就不在于这一分钟
还是两分半钟的差别。瓶颈更在于:
(1)能不能上难度(理解 algebra 和 formal/spatial operation)
(2)认知新事物的速度(而不是 replay standard algorithm 和已知
题型的速度)有多快。 |

Y********d 发帖数: 1478 | 20 免得你又删贴,我把你的回复copy全了。
虽然我娃离高中还有很多年,也不知道数学竞赛是否和她相关,我读你的帖子的理解就
是,
数学竞赛要求both proficiency in standard algorithms and ability in high-
order thinking skills,而高中数学不decay更侧重后者。
所以,你也不是盲目反对人肉竖式计算器,而是强调个体差异和最终目标。
赞客观,公允,和宝贵第一手经验。

t******l 发帖数: 10908 | 21 这个刚才就有个实战例子,娃在复习 2013 AMC 8 时,在 Problem 4 发生计算错误,
对不上选择枝。
我于是问娃这么简单的破题也能算错?娃立马罗罗嗦嗦地开始用学校教的 pre-algebra
verbal logics 开始 explain。天地良心啊,我又不是 verbal thinker,我立马被
娃搞昏头。
于是我对娃说,娃你不是已经会 algebra 了么,这题用 algebra 来解释,首先第一步
符号方程化,设每个人最初该付 x 美刀,于是:
8x = 7(x+2.5)
=> 8x = 7x + 7 * 2.5
=> x = 7 * 2.5
=> 8x = 7 * 2.5 * 8
(change order of operations)
=> 7 * 2.5 * 2 * 4 = 7 * 5 * 4 = 7 * 20 = 140

t******l 发帖数: 10908 | 22 好吧,我觉得你的疑惑是,你 presume:

(2)娃的数学方面主要的 information 来自于父母的问答,而不是来自于
父母 + AMC 标准答案 + 学校数学老师的解释。
What if 你的 assumption 不成立?
如果说实在的:
(第一)其实我现在不咋教大娃,也就是开车时聊聊概念。娃自己会去美国
数学计算题八对答案。我现在经常也就是 grade 一下,然后问问娃是不是
review 了错误。
(第二)我以前四年级教娃的时候,大部分时候也是用教具和比喻,lay out
the facts。至于具体的题目解题步骤,我主要就是 replay 一遍。
(第三)我觉得父母主要的任务是 layout facts,这些 facts 也包括父母
大脑中的 picture。

t******l 发帖数: 10908 | 23 另外 by the way,mathsisfun.com 上对于 probability 的解释还是不错的。
当然问题是,在学习的阶段,我们到底需不需要娃 replay 那些解释,还是首先
要能做题 problem-solving,解释以后慢慢跟进。
当然,我娃的风格是,撞上南墙做错题还看不懂解释以前,是绝不看解释类网页的。
我如果墙裂要求,她就给我上有政策下有对策,应付一下。所以这个 mathsisfun.com
虽然是我娃介绍给我的,但我估计娃多半没看下面这个 probability 的网页。
这里也有个问题,如果娃混日子型的,大人如果没有 create need (比如错了题
还看不懂解释,或者干脆屡败屡战),那强迫娃看解释搞成鸡飞狗跳,真还不如等
