Arthur Benjamin: Teach statistics before calculus!

Filmed:

Someone always asks the math teacher, "Am I going to use calculus in real life?" And for most of us, says Arthur Benjamin, the answer is no. He offers a bold proposal on how to make math education relevant in the digital age.

Now, if President Obama

invited me to be the next Czar of Mathematics,

http://e-vid.net/v/en/587-1

00:15

then I would have a suggestion for him

http://e-vid.net/v/en/587-2

2

7000

3000

00:19

that I think would vastly improve

http://e-vid.net/v/en/587-3

10000

2000

00:22

the mathematics education in this country.

http://e-vid.net/v/en/587-4

4

12000

3000

00:24

And it would be easy to implement

http://e-vid.net/v/en/587-5

5

15000

2000

00:27

and inexpensive.

The mathematics curriculum that we have

http://e-vid.net/v/en/587-7

19000

2000

00:31

is based on a foundation of arithmetic and algebra.

http://e-vid.net/v/en/587-8

8

21000

4000

00:33

And everything we learn after that

http://e-vid.net/v/en/587-9

25000

2000

00:37

is building up towards one subject.

http://e-vid.net/v/en/587-10

10

27000

3000

00:39

And at top of that pyramid, it's calculus.

http://e-vid.net/v/en/587-11

30000

4000

00:42

And I'm here to say

http://e-vid.net/v/en/587-12

12

34000

2000

00:46

that I think that that is the wrong summit of the pyramid ...

http://e-vid.net/v/en/587-13

13

36000

4000

00:48

that the correct summit -- that all of our students,

http://e-vid.net/v/en/587-14

14

40000

2000

00:52

every high school graduate should know --

http://e-vid.net/v/en/587-15

15

42000

2000

00:54

should be statistics:

http://e-vid.net/v/en/587-16

16

44000

3000

00:56

probability and statistics.

01:01

I mean, don't get me wrong. Calculus is an important subject.

http://e-vid.net/v/en/587-19

It's one of the great products of the human mind.

http://e-vid.net/v/en/587-20

2000

01:07

The laws of nature are written in the language of calculus.

http://e-vid.net/v/en/587-21

21

57000

4000

01:09

And every student who studies math, science, engineering, economics,

http://e-vid.net/v/en/587-22

22

61000

4000

01:13

they should definitely learn calculus

http://e-vid.net/v/en/587-23

23

65000

2000

01:17

by the end of their freshman year of college.

http://e-vid.net/v/en/587-24

24

67000

2000

01:19

But I'm here to say, as a professor of mathematics,

http://e-vid.net/v/en/587-25

25

69000

3000

01:21

that very few people actually use calculus

http://e-vid.net/v/en/587-26

26

72000

4000

01:24

in a conscious, meaningful way, in their day-to-day lives.

http://e-vid.net/v/en/587-27

27

76000

3000

01:28

On the other hand,

http://e-vid.net/v/en/587-28

28

79000

2000

01:31

statistics -- that's a subject that you could,

http://e-vid.net/v/en/587-29

29

81000

3000

01:33

and should, use on daily basis. Right?

http://e-vid.net/v/en/587-30

30

84000

3000

01:36

It's risk. It's reward. It's randomness.

http://e-vid.net/v/en/587-31

31

87000

3000

01:39

It's understanding data.

http://e-vid.net/v/en/587-32

32

90000

2000

01:42

I think if our students, if our high school students --

http://e-vid.net/v/en/587-33

33

1

92000

2000

01:44

if all of the American citizens --

http://e-vid.net/v/en/587-34

34

94000

2000

01:46

knew about probability and statistics,

http://e-vid.net/v/en/587-35

35

96000

3000

01:48

we wouldn't be in the economic mess that we're in today. (Laughter) (Applause)

http://e-vid.net/v/en/587-36

36

99000

3000

01:51

Not only -- thank you -- not only that ...

http://e-vid.net/v/en/587-37

37

102000

3000

01:54

but if it's taught properly, it can be a lot of fun.

http://e-vid.net/v/en/587-38

38

105000

3000

01:57

I mean, probability and statistics,

http://e-vid.net/v/en/587-39

39

108000

2000

02:00

it's the mathematics of games and gambling.

http://e-vid.net/v/en/587-40

40

110000

4000

02:02

It's analyzing trends. It's predicting the future.

http://e-vid.net/v/en/587-41

114000

02:06

Look, the world has changed

http://e-vid.net/v/en/587-42

from analog to digital.

And it's time for our mathematics curriculum to change

Why you should listen

Arthur Benjamin makes numbers dance. In his day job, he's a professor of math at Harvey Mudd College; in his other day job, he's a "Mathemagician," taking the stage in his tuxedo to perform high-speed mental calculations, memorizations and other astounding math stunts. It's part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner.

Benjamin is the co-author, with Michael Shermer, of Secrets of Mental Math (which shares his secrets for rapid mental calculation), as well as the co-author of the MAA award-winning Proofs That Really Count: The Art of Combinatorial Proof. For a glimpse of his broad approach to math, see the list of research talks on his website, which seesaws between high-level math (such as his "Vandermonde's Determinant and Fibonacci SAWs," presented at MIT in 2004) and engaging math talks for the rest of us ("An Amazing Mathematical Card Trick").
