Everybody seems to have a short memory, which is why people keep making mistakes. This is supposed to be why people study history. The history of the education reform movement from the 1960s through the 1990s seems to elude 21st century attempts at reform--tremendously sad, because there is so much to learn from the successes and failures of the time. Ted Sizer (actually a historian by training) was the main reformer of that era. His books (the "Horace trilogy" and others), his television appearances, his Congressional testimonials in Washington, the way he sold ideas to big corporations--all guided by his pursuit for better high schools--led everyone. The beauty was that Sizer could relate to everybody, the high school students and the college presidents, the teachers and the founders, the principals and the legislators. In this article, the author describes Sizer's accomplishments.
