1
Good morning, everyone. Let me begin with a quick question about how you study.
皆さん、おはようございます。まず、皆さんの勉強の仕方について簡単な質問をさせてください。
2
When an exam is coming, what do most of you actually do?
試験が近づいてきたとき、皆さんの多くは実際に何をしていますか。
3
If you're like most students, you read your notes again, and then again.
たいていの学生と同じなら、ノートを読み返して、そしてまた読み返しますよね。
4
It feels productive, and the material starts to look wonderfully familiar.
はかどっている気がしますし、内容もすっかり見慣れたものに思えてきます。
5
The trouble is that familiarity isn't the same thing as memory.
問題は、見慣れていることと覚えていることは同じではない、という点です。
6
Today I want to show you why testing yourself is far more effective.
今日は、自分でテストすることのほうがはるかに効果的な理由をお見せします。
7
Psychologists call this the testing effect, or retrieval practice.
心理学ではこれをテスト効果、あるいは検索練習と呼びます。
8
Retrieval simply means pulling information out of your memory without looking.
検索とは、何も見ずに記憶から情報を引き出すことです。
9
In two thousand and six, Henry Roediger and Jeffrey Karpicke tested this idea carefully.
2006年、Henry RoedigerとJeffrey Karpickeがこの考えを綿密に検証しました。
10
They asked university students to learn short passages about science topics.
彼らは大学生に、科学をテーマにした短い文章を覚えてもらいました。
11
One group simply read a passage four times, in four separate study periods.
あるグループは、4回に分けた学習時間で文章を4回読むだけでした。
12
Another group read it only once, and then tried to recall it three times.
別のグループは一度だけ読み、そのあと3回思い出そうとしました。
13
During those tests, they wrote down everything they could remember, with no help at all.
そのテストでは、何の手がかりもなしに、思い出せることをすべて書き出しました。
14
Five minutes later, the students who had reread the passage did noticeably better.
5分後のテストでは、読み返したグループのほうが明らかに成績が良かったのです。
15
So far, rereading seems to win, which is exactly what most of us would expect.
ここまでは読み返しの勝ちに見えますね。まさに多くの人が予想するとおりです。
16
But the researchers also tested everyone again one week later.
ところが研究者たちは、1週間後にも全員をもう一度テストしたのです。
17
And this time, the picture was completely reversed!
そして今回は、結果がまったく逆になったのです！
18
The repeated testing group remembered about sixty-one percent of the ideas.
繰り返しテストしたグループは、内容の約61%を覚えていました。
19
The group who had only reread remembered just forty percent.
読み返しただけのグループは、わずか40%でした。
20
In other words, rereading helped in the short term, but testing lasted far longer.
つまり、読み返しは短期的には役立ちましたが、テストの効果のほうがずっと長続きしたのです。
21
What surprised me most, though, was what the students themselves predicted.
ただ、私がいちばん驚いたのは、学生たち自身の予想でした。
22
Those who had reread four times felt more confident that they would remember the passage.
4回読み返した学生のほうが、文章を覚えていられると自信を持っていたのです。
23
Their sense of fluency fooled them, and that confidence turned out to be misplaced.
すらすら読めるという感覚が彼らを欺き、その自信は見当違いだったとわかりました。
24
So how can you put this into practice tonight?
では、今夜からこれをどう実践すればいいでしょうか。
25
After reading a chapter, close the book and write down everything you can recall.
1章読み終えたら本を閉じて、思い出せることをすべて書き出してください。
26
Then check what you missed, and test yourself again a few days later.
それから抜けていた部分を確認して、数日後にもう一度自分をテストしましょう。
27
It'll feel harder than rereading, but that struggle is precisely what makes memories last.
読み返すより大変に感じるでしょうが、その苦労こそが記憶を長持ちさせるのです。
28
See you next week, and do test yourselves before then!
では来週また会いましょう。それまでにぜひ自分をテストしてくださいね！

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
