In the United States the "Progressive Education Movement", starting in the 1880s and lasting for sixty years, helped boost American public schools from a budding idea to the established norm. John Dewey, a principal figure in this movement from the 1880s to 1904, set the tone for educational philosophy as well as concrete school reforms. His thinking had been influenced by the ideas of Fröbel and Herbart.[8][9] His reactions to the prevailing theories and practices in education, corrections made to these philosophies, and recommendations to teachers and administrators to embrace "the new education", provide a vital account of the history of the development of educational thinking in the late nineteenth and early twentieth centuries.
