Since the 1830s, public schools have spread into every corner of America. Then and now, what kind of people have been called to teach in these schools? This program explores the importance of educators in the lives of their students, emphasizing a teacher’s influence as role model, as upholder of society’s norms, and even as agent of social change. Dedicated women who spent their careers teaching newly freed slaves and turn-of-the-century teachers of immigrants are profiled, as well as exemplary instructors of today’s struggling teenagers. Education reformer Theodore Sizer, education historian David Tyack, and author Frank McCourt are featured. (56 minutes)
