 note = {[Abstract] This paper focuses on heightening researchers' awareness of the problems that could occur if instruments are not properly validated, which could ultimately end in obscured results. It will demonstrate a systematic approach to validating a Likert-scale instrument used to measure change across multiple occasions with multiple groups in an EFL context. It will detail many of the possible pitfalls that researchers may encounter when processing their data and solutions to overcoming these problems. This will be facilitated by utilizing the Rasch Rating Scale Model to expel confounding effects from the data and, thereby, present a more accurate representation of the actual changes that occur in a study.
[要旨] このことをふまえ, 本論文は上記のような長期的研究を行う研究者にとって測定手段を有効化することがいかに重要であるかを実証する。具体的には, EFLで複数の被験者グループを対象にした長期的研究において用いるリッカート尺度方式による測定手段の有効化の方法を, ラッシュ評定尺度モデルを使って例示する。またデータ分析の際多くの研究者が直面するであろう問題点やその解決方法も紹介する。, application/pdf},
