"You tryin' to change us?"A few seconds into my first class ever, a student asked a question that had no answer. Then, he walked out.It was a fitting introduction to City High, inner-city education, and what would soon become the most challenging experience of my entire life. I was a white, middle-class, Midwestern man thrown into a Philadelphia school that had performed so poorly it was surrendered to state control. My next two years as a teacher at City High were hectic, heartbreaking, and at times, hilarious. I met students whose own lives seemed more dramatic than anything you might find in the movies. There was Manny, an oversized class clown with Ivy League dreams and a million-dollar smile, a city kid who liked NASCAR and got kicked out of Catholic school for carrying nun chucks. There was Romeo, a kid who got arrested for making his own adult films and Randy, a kid whose father was serving life in prison for shooting a police officer. And there were others too, every one of them struggling to survive in a city that would witness more than 400 homicides in a single year.I taught them all. I taught through the whirlwinds of overworked teachers, underfunded classrooms, and educational policies that often seemed more puzzling than practical. I taught kids who seemed to provoke every emotion possible, laughter and love and rage, often all of them in a single period.Maybe I made an impact, maybe they changed. I know I did.My story is different than all those feel-good, happy-ending Freedom Writer type films that seem to appear in theaters every few years.It is real.
