Measuring Interactional Competence in a Japanese University EFL Speaking Context

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The ability to interact is an integral aspect of speaking proficiency. Therefore, methods of assessing interaction need to be incorporated into second language (L2) speaking tests. The main purpose of this exploratory study is to attempt to quantify interactional competence (IC) in a Japanese university EFL (English as a foreign language ...

Changed Minds and L2 Motivation: Reflections of Japanese EFL Students Living, Laboring and Learning in Vietnam

International Journal of Applied Linguistics, EarlyView.
ABSTRACT English as a lingua franca (ELF) is increasingly used for communication in many EFL contexts, including Vietnam. Although Japan and Vietnam have a long history of economic cooperation, for practical reasons, English typically functions as the medium of communication between the two groups. This study examines Japanese expats who had studied or

Examining the Effects of Synchronous Written Corrective Feedback During Computer‐Mediated Collaborative Writing: Feedback Type and Learner Perceptions

International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1194-1207, May 2026.
ABSTRACT Spurred by the advancement of educational technology, more language instruction has been offered in online environments. Consequently, teaching practices have had to adapt to digital platforms. Accordingly, teachers’ provision of synchronous written corrective feedback (SWCF) on digital texts has received increasing attention.
