## 华人家长热点议题之九——美国人的数学很差吗？（续）

“好主意！可是绳子并不到旗杆的顶端，还不能达到精确的目的。”

“很好！我们看到探寻真理的目标了，可是怎样才能测得这个仰角呢？”

Brainstorming 又开始了……

“太好了！我们向真理迈出了一大步！动手吧！”

“Bingo!”所有的同学欢呼起来，老师更是兴奋，看着他的学生，他好像看见了一颗颗智慧之星，看见了他的学生们都成了伟大的科学家……

1. 小红看一本126页的故事书, 已看了一些还剩38页, 小红看了多少页? （评：此题意义何在？看了多少页一目了然，怎么会先知道剩下的页数而要求看了多少页呢？不就是把简单的问题弄复杂了，让学生在数字游戏里转悠？）

2. 家具店运来45把木椅, 运来的折椅比木椅的3倍还多10把, 家具店共运来多少把椅子? （评：怎么会不知道共运来多少椅子？挨个数一下不比先知道折椅比木椅多多少倍更容易？）

3. 王庄乡有水田507公顷, 比旱田的3倍还少3公顷, 王庄乡有旱田多少公顷？（评：同样是一个脱离实际编造的问题，学生只是套公式摆弄数字，对解决现实问题几乎没有帮助）

“其本质是在争论衡量数学教育质量的标准问题”非常同意这个观点，也许在中国现有的教学基础上加强基础科学在实践中的应用，提高学生的科学思维能力。毕竟天才是少数，教育的本质不因该是培养天才而是让大多数普通人有基本谋生的技能。

I have a boy who is a 3rd grader and I saw algebra questions in his book the other day, many of them were similar to the "bad examples" raised in here, not much difference. E.g. Sue said that her family had 1.5 litter milk before breakfast, after breakfast, only 0.5 litter left. Is that possible?" Comparing to your book page problem, which one is worse? When I was in graduate school, I graded pre-calculus for Math department, the content was just about Chinese junior high level. The funny thing is that I got the answer sheet from the instructor and the answer sheet was wrong! In some colleges here, there is this class called "calculus using calculator" by the math department, you tell me.
kebob 文章的题目和内容很不匹配，题目说的是美国，文章的例子是加拿大的，不懂。
smallking People who made comments shall first go through the Chinese math education and the American way of education before making comments.

To understand math is to understand the fundamentals behind the math. It is to understand the logic, reasoning, step by step behind these elegant formula or questions.

At a higher level, to understand the universe and the laws of nature, you need really good at grasping math, not just remembering how to solve the questions.

The American way of math education to high school/undergraduate is totally superficial. Don't you see the 30 years of rapid economic growth in China; isn't that not related to great number of the students graduated in China that are well educated in math and sciences!

locke 游泳池和旗杆的题国内也作。用一节课来讲解旗杆的题，效率太低，可想而知，一学期能学到多少东西。看来加国的数学教学水平还真是差不少。
ubcdavid In study and research, the most important thing is to find the question, not the answer. How can you find the question, that is the goal and target of education in North America. Even you can get 100 in exam, that just means you can repeat others' works very well. That's the reason so many "stupid" professors leading so many clever students.

smallking math is the crown of the science. the current Chinese math education is much better, in my opinion, which teach the students, the fundamentals, not just something seems interesting in real life.

American/Canadian only learn the surface, or half-full. It will be very difficult for a country to grow without a large amount of graduates really understand math.

Nice!
