I take this subject very personally. I am a hearing impaired person.
During the Culinary Supervision and or Law class; this is when I introduce the subject of reasonable accomadations to the class using myself. I think why I am successful with explaining this is I use humor. 99% of the time I have at least 5 -8 students stay after class and ask me questions about my disability.
The goal is for the students to look at the next deaf person they see and be more positive.
