I do have some experience working with LD children because my brother has severe dyslexia. I know the frustration in trying to teach him when he has a very difficult time reading simple words on a page. Kids with dyslexia are not stupid, they just have a very difficult time reading. Try anything and everything you can to reach them. I guess this also goes for the behaviorally and emotionally disabled.
Patience is always a good virtue.
These kids will probably try their hardest if we show them htat we respect and care about them as people. From what I have seen and come in contact with the best way to deal with students that have been mainstreamed is definitely to have patience as well as show them that you care. Many of them just want to know that someone genuinely cares.
