Do you discuss something deliberately in class that's not exactly related to Art? I like to start my first lesson (especially to a new cohort of students) explaining to my students about the difference between equity and equality by introducing them my propaganda wall. In school, everyone recite the National Pledge during morning assembly daily. Since they are not going to receive the same treatment from me throughout the year, I think it's clearer to be explicit about my actions by adopting a single word from the National Pledge and began my lecture.
