ELL used to be LEP or some other acronym.
* ELL = English language learner
* LEP = limited English proficient
It doesn't really matter which term you use; the point is to help these kids learn English, and not just "playground" English. They need to learn English well enough to function successfully in academic settings.
Here are some sites with some ideas for you. (Hint: Whatever you learn to do for ELL students will work well for all your students!)
There are many others, but these seem to be among the best!
Use visual aids often.
Incorporate hands-on activities to demonstrate concepts.
Allow sufficient wait time.
Model spoken language, but refrain from embarrassing ELL students with verbal correction in front of others.
Prepare outlines for lectures and distribute to ELL learners.
Encourage skim and scan reading strategies for textbook assignments.
Avoid forcing language learners to speak. Encourage them to contribute when they are ready.
All look good.
But remember what I said above -- what works well for ELL students works well for all students.
Use these teaching strategies with all your students, and they'll all learn much more than if you don't. You also don't want to be treating the ELL students noticeably differently (e.g., handing only the ELL students outlines).
