英語の音読とシャドーイングがスピーキングに及ぼす効果

研究成果の概要 (和文) : 本研究は日本人大学生を対象とした音読およびシャドーイングの練習がスピーキングパフォーマンスに及ぼす影響を探った。1年目は音読とスピーキングのスコア、スピーキングの描写タスクによる発話データの言語的計量分析結果から、シャドーイングとスピーキングに有意な中程度の相関関係を確認した。2-3年目は音読とシャドーイングを組み合わせた長期的な授業における指導がリスニング中心の指導と比して、スピーキングの慎重に効果をもたらすかを探った。その結果、音読シャドーイング指導が、文法の正確さ・複雑な語彙使用を高める効果をもたらすことが分かった。

研究成果の概要 (英文) : This study examined the relationships among performances of reading aloud, shadowing, and speaking. It also studied the effects of reading aloud and shadowing instruction on speaking ability development. In the first study, it was found that shadowing and speaking had a positive relationship with a medium strength of correlation. On the other hand, reading aloud showed no significant relationship with speaking performance. It was concluded that reading aloud helped the learners take in learned linguistic knowledge rather than enhance their speaking performance directly. In the classroom research, it was found that in both the shadowing instruction group and the listening instruction group the participants improved their speaking performance. However, especially in the aspect of grammatical accuracy and vocabulary complexity, the shadowing group had a higher effect size than listening group.
