Jonathan Kozol is a grown-up who talks a lot about schools and the way they treat kids. He thinks that some schools treat some kids differently because of the color of their skin or the amount of money their families have. He wants all kids to have a fair chance to learn and be happy at school. He also writes books and tells stories about his experiences visiting different schools and talking to kids and teachers. He wants everyone to know how important it is to have good schools for all kids, no matter who they are or where they come from.
