Classroom gesture instruction on second language learners' academic presentations: Evidence from Chinese intermediate English learners

Gesture has been recognized as an important aspect of second language (L2) acquisition, playing a vital role in L2 communication. Previous research has shown that L2 learners' communicative efficacy can be facilitated through gesture mediation. In particular, L2 learners may find gesture a useful tool to deliver their subject-related academic presentations. However, whether classroom gesture instruction could boost L2 learners' gesture use in academic speaking context and their overall presentation performance has rarely been explored. Drawing on activity theory, this study aims to investigate the potential role of gesture instruction in intermediate L2 English learners' gesture use and their academic presentation performance. Our study found that L2 learners who received classroom gesture instructions showed significant improvement in their use of gestures, and outperformed the control group in a post-test presentation session, showing improvement in all gesture types among which beats were significantly increased. These findings confirm the teachability of gesture to enhance Chinese L2 English learners' academic presentation skills, proving gesture as an indispensable instructional component in English for Academic Purposes (EAP) classroom.
