Yes, I'm new at this too. I teach Diesel and Meavy Equipment Mechanics at a technical college and this year I have a Deaf student. I am looking forward to having him in my class but at the same time I'm Safety concerned too. has anyone out there gone through a mechanics class? My biggest concern is the Operations portion of the class where my students operate bull-dozers, excavators, backhoes etc. I presently communicate with them via walkie-talkies while they are operating. Whats the best way with the deaf? I'm old and not too computer literate so please excuse me if I make mistakes.
