ROCHELLE RILEY: Detroit teacher points out the schools' problems: "Across Detroit, teachers provide counseling, clothes or food and try to build self-esteem in some children who feel unworthy of learning. Nearly every day, they suspend instruction to calm disruptive kids. Teachers, particularly in high schools, combat rampant absenteeism. In the lower grades, some students are so transient their classes look entirely different by semester's end. Absenteeism is rampant in the high schools. Most schools need computers, photocopiers and additional supplies. "
