Outline of Final Research Achievements

In this research, I developed MAST (Mobile Application for Summary speaking Task) that offered English speaking practice using a virtual tutor and evaluated the effectiveness. The result showed two implications. First, virtual tutors for English speaking self-study could support how to speak a specific contents and to use appropriate words and as a result, learners could concentrate on grammatical encoding and speak longer sentences with few self-repair. Second, when learners used MAST for preparation for face-to-face practice, they could reflect more effectively on their speech in terms of not how to speak but what they should speak.

Academic Significance and Societal Importance of the Research Achievements

本研究ではバーチャルチューターが学びのパートナーとしたスピーキング自学自習が行えるシステムを開発し,その効果を量的な観点と質的な観点から明らかにした.この結果は,日本のような日常的に英語を話す機会の少ない非英語圏におけるより効果的な英語学習を行うための1つの方向性となり得ると考える.
また,バーチャルチューターによる自学自習を踏まえた上で対面活動を行い,その効果を自学自習と対面活動それぞれの学習プロセスを詳細に検証しながら評価することで,バーチャルチューターが担える役割と,対面活動が担える役割の可能性について示唆を提供することができた.
