Mr. Salazar, I love your approach. Not only are you teaching critical thinking skills, you are moving your students from just thinking of themselves as potential victims, to thinking of themselves as well-educated citizens who may be able to make a difference.
I also taught inner-city kids for a number of years in the Boston area. At one point, almost every Boston student I had knew someone–a family member or friend–who was a victim of gun violence. I wish I had thought of your approach then.
