Chances are your middle and high school teachers taught what's in the textbook: Christopher Columbus, early American settlers, the Revolutionary War, the Civil War, World War I, the Depression, and World War II. But what about the other historical events that have shaped America, like Seneca Falls, the Red Summer of 1919, Harvey Milk's political career and assassination, and our long history of environmental activism?
Schools won't teach this unless we ask for it (and help them do it.) To get a school/teacher you know started, send them to the Zinn Education Project, which offers more than 100 free, downloadable teaching activities for middle and high school classrooms. They also list hundreds of recommended books, films, and provide links to other websites that can help schools teach outside the textbook.
