ChatGPTでIELTS英語資格の記述問題学習・教材作成を試す

こんにちは、Vitalify AsiaのNihei です。普段は、PMやAI Specialistとして、生成AIなど、AIを使った案件のお手伝いをさせていただいています。
今日は、英語資格のIELTsのWriting試験の勉強をChatGPTと一緒にやってみようと思います。IELTsのホームページより以下のサンプル問題を使ってみます。

The chart below shows the number of men and women in further education in Britain in three periods and whether they were studying fulltime or part-time. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
問題文
下のグラフは、英国の高等教育機関在籍者の男女数を、フルタイムかパートタイムかによって示したものである。

Band 5.0 レベルの回答
The chart shows the number of men and women in further education in the UK between 1970/71 and 1990/91. The chart also shows if they were studying full-time or part-time.
In 1970/71, most men and women were studying part-time. The number of men in part-time education was about 1,000,000, while for women, it was about 700,000. Full-time education numbers were much lower for both men and women.
By 1980/81, the number of men in full-time education increased a little, and for women, it also grew slightly. The number of part-time students remained similar for both genders.
In 1990/91, more women joined education. The number of women in full-time education increased, and part-time education for women became much higher than before. The number of men remained stable.
Overall, the number of women in education increased more than men, especially in part-time education.
Band 6.0 レベルの回答
The chart illustrates the number of men and women in further education in Britain during three different periods: 1970/71, 1980/81, and 1990/91. It also distinguishes between full-time and part-time education.
In 1970/71, most men and women were engaged in part-time education. Around 1,000,000 men and 700,000 women studied part-time, while the number of full-time students was much lower. The number of full-time male students was slightly higher than females.
Over the next two decades, the number of people in full-time education gradually increased. By 1990/91, the number of full-time students had grown for both genders, with a more noticeable increase among women. Additionally, part-time education for women increased significantly, surpassing 1,000,000.
In contrast, the number of men in part-time education remained relatively stable over the years. Although full-time education among men also increased, the rise was not as sharp as for women.
Overall, while men consistently had higher numbers in part-time education, women experienced significant growth in both full-time and part-time education by 1990/91.
一見すると、5.0 と 6.0 は同じようですが、よく見比べると 5.0 の方は、文章が短く、単純な文法構造が多く、データを単純に羅列しているだけで、基本的な単語が多いですが、6.0 は 関係詞や副詞を使った接続が増え、比較を意識した表現が多く、語彙の幅が広く、具体的な表現があります。
またスコアを上げるためのアドバイスを貰うことができました。

このようにChatGPTを使うことで、英語の塾やIETLsの対策講座などで、人手の必要な採点部分をAIにサポートしてもらうことができたり、個人でも学習を進めることができるようになるかと思います。
今回はシンプルに検証をしてみましたが、具体的なIELTsの採点基準をAIに覚えさせることで、採点基準を考慮して、納得感のある解説を作成してくれて効果的な学習ができたいできるかと思います。
他にも、例えば、自分でどこかからグラフをとってきてそれを元にChatGPTに練習問題を作成してもらい、模範回答を生成してもらい、学習をする、といった使い方も可能かと思います。

試しに、政府の統計の資料から、問題を作成してみました。
IELTS Writing Task 1 - 練習問題
課題:
You should spend about 20 minutes on this task.
The chart below illustrates Japan's population distribution by age and gender in 2020.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
また、模範回答を Band 5.0 レベルで作成してもらいました
The chart shows the population of Japan in 2020, divided by age and gender. The blue bars represent males, and the pink bars represent females. The population is shown in different age groups, from 0 to 100+ years old.
One main feature of the chart is that older people make up a large part of the population. The number of people aged 65 and over is much higher than younger people. In particular, the number of women is higher than men in older age groups.
Another important point is that the younger population is smaller. The number of children (0–4 years old) is much lower than the middle-aged population (40–59 years old). This shows that Japan has a low birth rate.
In conclusion, the chart shows that Japan has an aging population. The number of old people is increasing, while the number of young people is decreasing. This may cause problems in the future, such as a smaller workforce and higher costs for elderly care.
解説
Band 5.0 のポイント:シンプルな文法と語彙: 難しい単語は使わず、簡単な表現で説明。
基本的な比較: "higher than", "lower than", "much smaller than" などの単純な比較表現を使用。
文章の流れ: イントロ → 特徴1(高齢者が多い)→ 特徴2(若年層が少ない)→ 結論、の構成。
スコアを上げたい場合は、比較を増やす、より具体的なデータを入れる、語彙を強化する ことがポイントになります!
このような形で出来ましたね!
これを応用することで、ご自身の学習に活かしていただくことはもちろん、学校の先生の採点や問題作成・解説を作る時間の削減になることも可能かと思います。
ぜひご参考になりましたら幸いです。
