Research on translingualism in Taiwan has so far observed existing translingual practices occurring in language classrooms. While it is important to investigate how translingualism is taking shape in Taiwan in its current form, what is missing is an exploration of the pedagogical applications of translingualism that have yet to occur and how it can be adopted. This article focuses on envisioning a certain future in which language teacher education in Taiwan is willing to take on a translingual approach and focus on fostering translingual teacher identities. What would such an endeavor look like? How would it be implemented? In this article, I will start by giving an introduction to the importance of language teacher identity and translingualism, and then shift to demonstrating the benefits translingualism can bring to teacher education programs and how translingualism can be enacted.
