One of the things that I try to incorporate into my classroom culture is respect. Students are to address any adult that comes into the classroom as "ma'am" or "sir". I also address them as such. Students are also taught to listen (not talk) while someone is talking in the classroom, whether it be myself or another student. They are reminded to show respect to fellow classmates and teachers throughout.
I believe that respect is something that many students have lost, no matter their socioeconomic situation.
