This book provides an overview of an action research model which utilizes the Common European Framework of Reference for Languages (CEFR) and stresses the importance of systematically researching classroom practice. Undertaken in a Japanese educational context, the focus of the book is squarely on classroom-based CEFR-focused action research concerning issues that all educators face, such as course design, materials development/selection, classroom implementation, learner autonomy and assessment.
