and you anticipated that reaction, you waited for it,

and it came back, and the person hated it?

相手の反応を期待して待ちますが

in which I spent every working day of the last six years. (Laughter)

that doesn't want it, but is forced by law to buy it.

法律なので、とモノを売るのです

So there's a useful stereotype about students that I see,

説明に便利な生徒の典型例があります

皆さんにも当てはまるかもしれません

And both of these facts say less about you or my students

than they do about what we call math education

To start with, I'd like to break math down into two categories.

One is computation; this is the stuff you've forgotten.

1つは計算。お忘れだと思います

例えば、2次方程式の因数分解です

This stuff is also really easy to relearn,

1より大きい首位係数のものです

provided you have a really strong grounding

数的推論の基本が出来ていれば

of math processes to the world around us --

This is what we would love students to retain,

even if they don't go into mathematical fields.

数学を志すかどうかに関わらず

This is also something that, the way we teach it in the U.S.

生徒に身につけて欲しい項目です

why that's such a calamity for society, what we can do about it

and, to close with, why this is an amazing time

そんな教育に対して何ができるか、です

驚くべき時代なのかにも触れます

One is a lack of initiative; your students don't self-start.

1つは率先力欠如で、自ら学習しません

and immediately you have five hands going up

asking you to re-explain the entire thing at their desks.

また全て説明してくれと言うのです

re-explaining concepts three months later, wholesale.

which describes 99 percent of my students.

David Milch, creator of "Deadwood" and other amazing TV shows,

「デッドウッド」の創作者のデイビッド ミルチ氏は

because he saw that when people fill their mind

with four hours a day of, for example, "Two and a Half Men," no disrespect,

「チャーリーシーンのハーパーボーイズ」を

in such a way that they expect simple problems.

He called it, "an impatience with irresolution."

単純問題を期待するようになるというのです

You're impatient with things that don't resolve quickly.

彼の言う「決断できないじれったさ」です

You expect sitcom-sized problems that wrap up in 22 minutes,

すぐ解決しないものに我慢できないのです

three commercial breaks and a laugh track.

22分で問題解決するホームコメディー式を望みます

what you already know, that no problem worth solving is that simple.

解決価値のある問題は単純ではありません

because I'm going to retire in a world that my students will run.

将来生徒の指揮下で暮らすのですよ

役に立たないことをしているのです

I'm here to tell you that the way our textbooks -- particularly

mass-adopted textbooks -- teach math reasoning

it's functionally equivalent to turning on "Two and a Half Men" and calling it a day.

「ハーパーボーイズ」を観るのと同じです

In all seriousness. Here's an example from a physics textbook.

さてこれが例です。物理の教科書です

that you have exactly three pieces of information there,

この1つ1つがやがて公式となり

And ask yourself, what problem have you solved, ever,

where you knew all of the given information in advance;

どんなものを解決したことがありますか

where you didn't have a surplus of information and you had to filter it out,

情報を全て入手している場合ですよ

or you didn't have sufficient information

情報が余分にあれば取捨選択したでしょう

I'm sure we all agree that no problem worth solving is like that.

And the textbook, I think, knows how it's hamstringing students

有価値の問題でそのようなものは皆無です

because, watch this, this is the practice problem set.

教科書も生徒の思考力を阻害しています

When it comes time to do the actual problem set,
