生成AIで英検3級の問題を作るプロンプトの例

2025/05/20

さて、先日来、英検3級の対策をしている話をしていたかと思いますが、今日は、生成AIを使って、英検3級の問題を作ってしまう話です。 生成AIに「英検3級の問題を作って」と言うと、恐らく何かしら問題は作ってくれると思いますが、それが、対話文の問題なのか、長文読解の問題なのか、ライティングの問題なのか、良くも悪くも生成AIは適当に作ってくれます。これをハルシネーションと呼んだりしています。 生成AIを使ったことがある方はわかると思いますが、生成AIにときには対話的に上手に教えて、やって欲しいことをやってもらわなければなりません。これは人に仕事を頼むときと同じです。言われたことしかしないのは、半ば当然のことで、職場にもよりますが、忖度できる人を優秀とするのは、指示する人の能力が低いと私は見ています。生成AIは、適当に処理してくれますが、忖度してくれるほどではありません。だからより具体的に説明し、お願いしなければならないのです。

私は、生成AIに順番に以下のようなお願いをして、英検3級の問題を作成しました。でも、逆に言ってしまえばこんなもんです。作成にかかった時間は、15分ぐらいだったでしょうか。思ったのですが、これは学校の先生が問題作成にかける時間が大幅に削減されたはずですね。先生は忙しいと聞きますが、本当ですかね。

英文 My name is Sarah, and I live in a small town near the mountains. Every morning, I wake up early and go for a walk. I love listening to the birds singing and watching the sunrise over the mountains. After my walk, I prepare breakfast for my family. We usually eat toast, eggs, and fruit together. Then, I go to work at the local bookstore. I enjoy helping customers find interesting books to read. In the afternoon, I take a break and drink tea while reading a book.
