Education lecturer Keith Catone will discuss how teaching is inextricably linked to social justice and activism. Catone, who joined the Annenberg Institute for School Reform, is the author of a book titled "The Pedagogy of Teacher Activism: Portraits of Four Teachers for Justice," which shares the stories of teacher activists, and how they became social change agents. A book signing and reception will follow. The event begins at 4:30 p.m. in the Watson Institute for International and Public Affairs, Joukowsky Forum, 111 Thayer St.
