Practice Spread Over Three Weeks Helped

音声・ゲームはこちらから

1Students did better on a math test after they spread their practice over three weeks, a study found. Researchers in the US and the UK did the study.

2The study was done with 99 students at a large school in the UK. The students were 11 or 12 years old. They learned two new kinds of math problems. For one kind, they solved 12 problems in one class. For the other kind, they solved four problems a week for three weeks.

3About a month later, the students took a test. Their scores were higher for the kind they practiced over three weeks. Each student tried both ways, so the researchers could compare them.

4The students also guessed their scores before the test. After practicing all at once, they thought they would do better than they really did. After practicing over three weeks, their guesses were close.

5The study was small, and all the students went to one school. Both ways used the same number of practice problems, 12.

全文訳

1練習を3週間に分けた生徒のほうが、数学のテストでよい点を取った、という研究が出ました。アメリカとイギリスの研究者たちが、この研究をしました。

2研究には、イギリスの大きな学校の生徒99人が参加しました。生徒たちは11歳か12歳でした。生徒たちは、新しい2種類の数学の問題を学びました。1つ目の種類は、1回の授業で12問を解きました。もう1つの種類は、1週間に4問ずつ、3週間かけて解きました。

3約1か月後、生徒たちはテストを受けました。3週間かけて練習した種類の問題のほうが、点数が高くなりました。どの生徒も両方のやり方を試したので、研究者たちは2つを比べることができました。

4生徒たちは、テストの前に自分の点数の予想もしました。まとめて練習したあとは、実際よりもよい点が取れると思っていました。3週間かけて練習したあとは、予想がほぼ当たっていました。

5研究は小さなもので、生徒は全員が1つの学校に通っていました。どちらのやり方も、練習した問題の数は同じ12問でした。

文法ポイント:前置詞のあとの動名詞(after ~ing)

前置詞(after, before, for など)のあとに動詞を置くときは ~ing の形(動名詞)にする。本文の After practicing all at once は「一度にまとめて練習したあとで」。after practice ではなく after practicing と、動詞を ~ing にしている。
