How do you handle language interference in large classes?

A discussion in Teaching English in Indonesia on the SpeakWise Indonesia teacher forum.

We've been thinking about the challenges of teaching English in our large classrooms, where L1 often takes center stage. A teacher in our community recently shared their struggle with students relying heavily on Indonesian in discussions, which made us wonder: how do you encourage English use while still being respectful of their native language? We invite you to share your experiences and strategies for balancing this delicate interplay—it could inspire many of us trying to navigate similar waters!
