What does it mean to make content comprehensible?
Imagine for a moment that you are sitting in a classroom in a foreign country surrounded by new classmates and a teacher speaking a language that you don't speak. Keep in mind, you have to stay all day and you are expected to follow directions, do the work, and understand the language.
How would you do? Would you become frustrated? Would you get off task? Maybe begin to fidget, doodle, or get mad? Sometimes when our ELLs experience this, they react in ways that we may not understand. Learning a new language, culture, and content is not an easy task by any means. It's important that we respect the job they are doing and support them through it.
The best way to support their content needs is to make content comprehensible.
