Jim Vera teaches government at Oswego East High School. He often has his students, mostly sophomores, stand in all four corners of the classroom. The corners are marked "Agree," "Disagree," "Strongly agree" and "Strongly disagree."
He starts small. Do we have good sports programs here? They all pick a corner. Then the debate escalates until, eventually, they're discussing topics like if it's okay to burn the American flag.
