How do you foster critical thinking in large classes with diverse English proficiency levels?

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

We've been thinking about the unique challenges of teaching English in our large Indonesian classrooms, where students might have vastly different levels of proficiency and backgrounds. This raises an important question: how can we create an environment that encourages all students to develop their critical thinking skills, despite the language barriers and curriculum pressures we face? We invite you to share your personal experiences and strategies that have worked for you in navigating this complexity together.
