A small group of students sat around a table Friday morning reading about World War II. As the students discussed what they had read, they realized they were helping each other learn. "It helps me learn more if we talk about it," said Chandler Dial Watson, a fifth-grade student at Centennial Arts Academy, "If I don’t get everything, maybe they’ll help me understand it better." Which is exactly what his teacher, Heather Weiser, is trying to do.
