Now, if President Obama
0
12160
3000
現在,假如歐巴馬總統
00:15
invited me to be the next Czar of Mathematics,
1
15160
4000
邀請我擔任下一個數學教育總管
00:19
then I would have a suggestion for him
2
19160
3000
我將對他提個建議
00:22
that I think would vastly improve
3
22160
2000
我認為將會大幅改善
00:24
the mathematics education in this country.
4
24160
3000
國內的數學教育
00:27
And it would be easy to implement
5
27160
2000
而且可以很容易實施
00:29
and inexpensive.
6
29160
2000
而且費用不多。
00:31
The mathematics curriculum that we have
7
31160
2000
我們現在的數學課程
00:33
is based on a foundation of arithmetic and algebra.
8
33160
4000
是以算術與代數為基礎,
00:37
And everything we learn after that
9
37160
2000
而在那之後所學的一切
00:39
is building up towards one subject.
10
39160
3000
都在朝著同一個主題發展
00:42
And at top of that pyramid, it's calculus.
11
42160
4000
在這金字塔的頂端,就是微積分
00:46
And I'm here to say
12
46160
2000
我在這裡要說
00:48
that I think that that is the wrong summit of the pyramid ...
13
48160
4000
我認為這是個錯誤的目標
00:52
that the correct summit -- that all of our students,
14
52160
2000
而正確的目標,對全體學生而言
00:54
every high school graduate should know --
15
54160
2000
每一個畢業生應該知道的
00:56
should be statistics:
16
56160
3000
應該是統計
00:59
probability and statistics.
17
59160
2000
機率與統計
01:01
(Applause)
18
61160
2000
鼓掌聲
01:03
I mean, don't get me wrong. Calculus is an important subject.
19
63160
4000
請別誤會,微積分是個重要的學科
01:07
It's one of the great products of the human mind.
20
67160
2000
它是人類心智最重要的產物之一
01:09
The laws of nature are written in the language of calculus.
21
69160
4000
大自然的定律是以微積分來描述的
01:13
And every student who studies math, science, engineering, economics,
22
73160
4000
每一個學習數學、科學、工程、經濟的學生
01:17
they should definitely learn calculus
23
77160
2000
他們絕對需要學習微積分
01:19
by the end of their freshman year of college.
24
79160
2000
在他們大一就得學會
01:21
But I'm here to say, as a professor of mathematics,
25
81160
3000
但身為一個數學教授,我要說
01:24
that very few people actually use calculus
26
84160
4000
很少人會實際用到微積分
01:28
in a conscious, meaningful way, in their day-to-day lives.
27
88160
3000
以有意識、有意義的方式,用在日常生活中
01:31
On the other hand,
28
91160
2000
但另一方面
01:33
statistics -- that's a subject that you could,
29
93160
3000
統計學--是你可以應用的學科
01:36
and should, use on daily basis. Right?
30
96160
3000
並且應該在日常生活中使用的,對嗎?
01:39
It's risk. It's reward. It's randomness.
31
99160
3000
它討論風險、報償、隨機性
01:42
It's understanding data.
32
102160
2000
它是了解數據的工具
01:44
I think if our students, if our high school students --
33
104160
2000
我想,如果我們的學生,
01:46
if all of the American citizens --
34
106160
2000
如果所有的美國人民
01:48
knew about probability and statistics,
35
108160
3000
懂得機率與統計學
01:51
we wouldn't be in the economic mess that we're in today. (Laughter) (Applause)
36
111160
3000
我們就不會陷入今天這場經濟風暴
01:54
Not only -- thank you -- not only that ...
37
114160
3000
不止這樣
01:57
but if it's taught properly, it can be a lot of fun.
38
117160
3000
如果教法適當,它可以是很有趣的
02:00
I mean, probability and statistics,
39
120160
2000
機率與統計
02:02
it's the mathematics of games and gambling.
40
122160
4000
它是遊戲與賭博的數學
02:06
It's analyzing trends. It's predicting the future.
41
126160
4000
它分析趨勢、預測未來
02:10
Look, the world has changed
42
130160
2000
你看,這世界已經改變了
02:12
from analog to digital.
43
132160
3000
從類比式的變成數位式
02:15
And it's time for our mathematics curriculum to change
44
135160
3000
也是改變我們數學課程的時候了
02:18
from analog to digital,
45
138160
2000
從類比式變成數位式
02:20
from the more classical, continuous mathematics,
46
140160
4000
從古典、連續式的數學
02:24
to the more modern, discrete mathematics --
47
144160
3000
變成更現代、分離式的數學
02:27
the mathematics of uncertainty,
48
147160
2000
探討不確定性的數學
02:29
of randomness, of data --
49
149160
2000
探討數據的隨機性
02:31
that being probability and statistics.
50
151160
3000
那就是機率與統計
02:34
In summary, instead of our students
51
154160
2000
簡要的說,與其
02:36
learning about the techniques of calculus,
52
156160
3000
讓學生學微積分
02:39
I think it would be far more significant
53
159160
3000
我想更重要的是
02:42
if all of them knew what two standard deviations
54
162160
3000
讓他們了解,距離平均值兩個標準差
02:45
from the mean means. And I mean it.
55
165160
3000
代表什麼意思,會更有意義
02:48
Thank you very much.
56
168160
2000
謝謝大家
02:50
(Applause)
57
