Anyone who cares about what schools teach and how their students learn will be interested in the memoir（回忆录）of Ralph W. Tyler. Ralph W. Tyler is one of the most famous men in American education.

Born in Chicago in 1902, brought up and schooled in Nebraska, the 19-year-old college graduate Ralph Tyler became hooked on teaching. So he changed his major from medicine to education.

While he was working at the University of Chicago, he got to know two famous educators, Charles Judd and W. W. Charters, whose ideas of teaching and testing had an effect on his later work. In 1927, he became a teacher of Ohio State University where he further developed a new method of testing.

Tyler became well-known nationally in 1938, when he carried his work to the University of Chicago.

Tyler was the first director of the Center for Advanced Study at Stanford, a position（职位） he held over 10 years. There, he firmly believed that researchers should be free to look for an independent spirit in their work.

Although Tyler officially retired（退休）in 1967, he never actually retired. He served on many educational organizations in the United States and abroad. Even in his 80s he traveled across the country to advise teachers on how to set goals that develop the best teaching and learning within their schools.
