Once the fight to provide free education for all children had been won, educators turned their attention to the quality of that education. To find out more about learning and the learning process, American schools looked to Europe. In the 1860s, they discovered, and for about 20 years were influenced, by Pestalozzi. His belief was that the goal of education should be the natural development of the individual child, and that educators should focus on the development of the child rather than on memorization of subject matter that he or she was unable to understand.
