My older sister Jean teaches writing at Indiana University east. She and I sometimes talk about how a writer can bring the voices and lives of ordinary people to wider notice.
She’s recently developed a course that gets students to write about “real people and real events,” and then get that work out of the classroom to a wider public. I think it’s a great way to use the arts — read this article, and see what you think: http://www.homepages.indiana.edu/042205/text/life.shtml
I think there are some interesting paralells to her class, and what we do in churches — learn to listen to, learn to really see other people, and figure out ways to integrate the arts into ordinary lives.
