I typical talk about mindful and cross cultural competence at the begining of every class. I also usually define diversity to include students with various disability. Most students with learning disability are comfortable discusing their disability in class. When they do, I find that it excites great sensitivity among other students. I have has a student with PTSD once in my class who jumped and hid under the table. The fellow students were compationate and helpful due to the fact that we discussed it.
