Effect of modality and task type on interlanguage variation

Abstract

AbstractAn essential component for assessing the accuracy and fluency of language learners is understanding how mode of communication and task type affect performance in second-language (L2) acquisition. This study investigates how text-based synchronous computer-mediated communication (SCMC) and face-to-face (F2F) oral interaction can influence the performance of language learners in producing grammatical forms accurately when learners of English as a second language complete different tasks in their L2. Findings show a systematic variability in learner interlanguage that depends on mode of communication and task type. L2 learners used articles more correctly and produced advanced-stage questions more frequently in text-based SCMC than in F2F. These findings suggest that task types and the mode of communication in which a task is completed need careful selection based on pedagogical purposes in order to maximize L2 learning and better evaluate L2 performance.
