The problem is language. There are diverse languages within the student base. Instead of using parts of their native language its time to be strong with use of proper english. Yup, teach them to speak like a Haole! No more pidgin! It aint gonna happen overnight, but their vocabulary will improve, amongst all of their language skills. This is not intended to kill their native language, but it is intended to increase their potential for the future. I like the Hawaiian Immersion concept. Can do the same thing with English!
