Abstract
Second language acquisition (SLA) courses in US higher education often emphasize monolingual frameworks, despite the increasingly multilingual reality of US classrooms. With the shifts shaping the Multilingual Turn, these courses present opportunities for growth and renewal. As educators in graduate programs, we have sought to integrate critical perspectives, including translanguaging and other approaches to foster more liberatory and democratic teaching practices. However, we continue to explore ways to enhance these foundational courses. This article details a critical peer collaboration between two researcher–practitioners from different higher education institutions, aimed at improving their respective Foundations of SLA courses. We engaged in a mutual exploration of two SLA-focused courses offered to pre-service and in-service teachers, reflecting on our development as teacher educators. Our collaborative study was guided by two primary questions: (1) How do translanguaging pedagogies inform the approach and implementation of each course? (2) How can these courses be strengthened on the basis of shared experiences and practices? We approached our reflections through a collaborative narrative inquiry conducted over eight sessions. This article recounts the scope and nature of this collaboration, illustrating how translanguaging and critical perspectives were integrated into our courses, maps future improvements, and highlights the potential of such critical peer collaborations in fostering small-scale professional development communities.
