“…On the one hand, student feedback literacy development depends on four levels of contextual factors, including textual level (e.g., features of feedback), interpersonal level (e.g., learners’ relationship with the teacher), instructional level (e.g., methods of assessment), and sociocultural level (e.g., educational policy in a society). Teacher, as a key agent of the classroom ecosystem, creates learning resources that are likely to be used by students (Q. Liu & Chao, 2018 ) in each of the four levels. Moreover, an ecological perspective emphasizes the interplay among resources in the classroom ecosystem and the interaction between micro-level (e.g., classroom instruction), meso-level (e.g., school community), and macro-level contexts (e.g., wider sociocultural contexts) in a holistic–systemic manner (Bronfenbrenner, 1979 ; Cowie & Khoo, 2018 ).…”
