AbstractThis study explores how preservice English teachers in China perceive and leverage their Chinese and English linguistic repertoires in ELT methodology training, and how a reflective understanding of their use of these repertoires can contribute to their development as teachers. To understand how their practices and conceptualizations of language and teaching are in accord with an orientation toward or away from principles of Global Englishes Language Teaching (GELT), we drew on theories of translanguaging space and stance (García, Ibarra Johnson, & Seltzer, 2017; Li, 2011) and the GELT framework (Rose & Galloway, 2019) to examine preservice teachers' experiences in teacher training. Through multimodal conversational analysis of lesson recordings, we found that preservice teachers created translanguaging spaces to utilize different languages in the critical negotiation of pedagogies. In addition, they displayed traslanguaging stance by strategically incorporating multimodal and multicultural resources in microteachings. We also carried out semistructured interviews in which the preservice teachers, influenced by factors such as language ideologies and curriculum design, displayed mixed views toward translanguaging practices in teacher training, and the ELT classroom. By investigating the feasibility of GELT in TESOL teacher training in China, this study emphasizes the need to empower preservice teachers as critical agents in terms of assessment design and curriculum delivery for sustainable Global Englishes‐oriented innovations to occur.
