Working With Special English Needs Students?

[cathyh]

I'm working with students who have special needs in learning English. They are ESL learners. My goal is to improve their accent/pronunciation. For example, I found that most Asian students often miss the ending sounds like "s" or "t" when speaking English. I would like to know some of the speaking problems that your English learners have (Spanish or Asian) and your teaching strategies in helping them to improve. Thank You.
