This paper reports on a study investigating changes in L2 motivation for Japanese learners of English as they completed their first communicative English language course at university. I aim to describe the strength and structure of students’ motivation and the degree to which these changed over one semester. A 36-item questionnaire was used to measure components of the L2 Motivational Self System and International Posture. The questionnaire was administered twice to 202 second-year university students in Japan: during the first week of the semester and 11 weeks later. Structural equation models were created to describe the causal relationships between motivational variables for the two time periods. Paired t tests revealed that both motivated learning behavior and ought-to L2 self significantly increased over the semester. A comparison of the two models indicated that there was a change in the motivational structure from Week 1 to Week 12.
本研究は、英語学習者の動機づけの強さと構造、及びその変化に焦点をあて、日本人大学生の外国語（L2）に対する動機づけの変化を調査した。大学で最初に履修するコミュニケーション英語の授業を対象に、第2言語習得を動機づける自己システム（L2 Motivational Self System）と国際志向性の2側面を測定する36項目からなる質問紙を作成し、2年生202名に対して授業第1週目とその11週間後に調査を実施した。分析は、まず構造方程式モデリングで2回の調査間の動機づけの変化を分析し、それに基づき対応のあるt検定を実施した。分析の結果、動機づけの高い学習行動と義務自己ought-to selfに関する数値が1学期を通して向上したことが明らかになった。
