Transition of medium of instruction in bilingual education in Aba Prefecture

Abstract The medium of instruction (MoI) in the bilingual education of Aba Tibetan and Qiang Autonomous Prefecture is regulated through two modes. The first stipulates that Putonghua should be used for most school subjects, while the second requires exclusive use of Putonghua as the MoI for all subjects. In 2023, a field trip was conducted to investigate the ongoing implementation of MoI in bilingual schools for Tibetan students in Aba Prefecture. This research initially examines the current bilingual education situation for Tibetans in two local schools, with a focus on classroom teaching supported by the first MoI mode. It reveals that translanguaging pedagogy is a primary practical strategy employed to adapt to the transition from the first MoI mode to the second. Furthermore, it scrutinises attitudes and localised strategies of teachers, students and parents towards this transitional process, aiming to provide a comprehensive understanding of the current medium of instruction for Tibetan students. The findings indicate that (1) teachers’ translanguaging practices significantly contribute across three dimensions; (2) stakeholders’ attitudes towards bilingual education transformation vary; and (3) partial national initiatives offer support to promote the transition in different ways. Finally, this paper briefly summarises existing discrepancies related to MoI transitions and translanguaging practice, and offers insights into future developments in MoI transition for minority ethnic students attending bilingual schools in China.
