The present study aims to explore an embodied approach to students' deep learning; specifically, how deep learning is interactively achieved through teachers' languaging dynamics and multimodal representations in interactive lecturing in L2 higher education (HE) contexts. The purpose is to understand how an instructor's embodied and multimodal pedagogical practices of interactive teaching facilitate students' active classroom engagement in lecture sessions that are often considered a form of passive knowledge transmission. The case study focuses on the languaging dynamics mobilised by the target teacher participant, who has been recognised as a representative of teaching excellence due to an international background and rich localised teaching experience. Aligned with the theoretical underpinnings of an embodied approach to learning from a constructivist perspective, this study focuses on the multimodal repertoire employed by the teacher's use of gestures to stimulate students' responses to the pedagogically designed high-order questions. We argue that this complementarity encourages thinking and active learning in the knowledge transfer. Further, this embodied interactive teaching mode with the affordances of gestures not only supports learning potential for information transmission but also affords action potentials for cognitive thinking and projected interaction for knowledge transformation in the active learning process.
