This article draws upon the history of teacher education to provide an introduction to four competing pedagogical philosophies. These four philosophies battled for control over curriculum for teachers during the period from 1890 to 1930. I begin by defining curriculum for teachers to include the liberal, the professional, and the experiential dimensions. Then, I identify four interest groups that sought to gain power over curriculum for teachers. I categorize these interest groups as the traditionalists, the integrationists, the technicians, and the romantics. Then, I explain how leading individuals from each interest group answered questions regarding human nature, the purpose of schooling, and curriculum for teachers. Finally, I argue that education schools should revitalize the integrationist tradition within pedagogical philosophy. This view has been forgotten for nearly 50 years, and the profession of teaching has suffered because of it.
