Abstract
This pilot study presents an analysis of the EFL writing produced by Japanese university students (n = 474) in core English classes. Students were asked to write one post a week on the microblogging platform Tumblr over 15 weeks. The blog posts were manually copied, pasted, and compiled
into a microblog corpus. The writing was then analyzed using Compleat Lexical Tutor. A separate
word list, including target words from the textbooks used in class, was also used. Analytical tools were
used to gain a better understanding of how students were learning and using the words when writing.
The findings show an initial 63.67% coverage of target words. However, the coverage dissipates when
analyzed for repeated word use. In turn, the analysis of words that were not covered reveals several
interesting findings. Examples of frequently used words and phrases are presented with the further intent of developing a research-based approach to improving pedagogy for writing skill in the Japanese
English as a Foreign Language (JEFL) context.
この予備実験では、日本人の大学生（n = 474）が必修英語授業で作成したEFL文章の分析を書いた。学生はマイクロブログ
と言うのTumblrに週1回で投稿するように依頼された。ブログ記事は手動でコーピーが取れ、マイクロブログコーパスにまとめら
れた。それから文章はCompleat Lexical Tutorを使って分析を行った。授業で使用されている教科書の中から対象となる単語を
含む別の単語リストも使用した。分析手段は、学生がどのように学んでいるか、そして書くときに言葉を使っているかのより良い
理解を得るために使われた。調査結果は文法狙いとターゲット語彙の最初の63.67％の適用範囲を示している。ただし、単語の
繰り返し使用について分析すると範囲は失われる。それに加えて、カバーされていない語彙の分析は、いくつかの興味深い発見
が得られた。頻繁に使用される語彙やフレーズの例は、英語は外国語として（ＪＥＦＬ）の文脈での文章力を向上させるための
研究ベースのアプローチを開発するという目的を持って提示される。
