The Factors Which Activate the Interaction Among the Learners in the Learning Group : From the Viewpoint of Fostering Junior High School Students' Positive Attitude on Communicating in English in English Classroom [PDF]

open access: yes, 1998
本研究の目的は、学習集団がどのような要因を備えていれば、学習者が積極的にインターラクションを行うことができるのか、日本人中学生の英語教育の視点から検討するものである。生徒が英語でコミュニケーションを行なおうとするとき、学習集団において心理的、社会的な問題が妨げとなり、話すことが躊躇される場合があるという。そこで、集団カウンセリングの七つの条件、学習者の性格、リーダーシップ、学習者間相互の尊敬と承認、という四つの側面から学習集団に必要とされる要因が検討された。さらに具体的な斑学習の進め方を検討し ...
