This is the sixth segment in a series on K-12 education. Although John Dewey, the originator of “progressive education,” defied most of the cultural, moral, and economic norms of his era, his message nevertheless somehow mainstreamed its way into K-12 schools nationwide. Dewey characterized himself as a “democratic socialist.” Over the years, his writings increasingly underscored an aversion to the free-market system; an abhorrence of religion, especially Christianity; a distaste for educational basics such as reading and writing; and finally, in 1928, an admiration for Soviet schooling — for the creation of what he called a “collectivistic mentality.” Given the traditionalistic norms of the 1920s and 30s, the likelihood of his affecting a sea change in education seemed about as likely as the United States replacing the Constitution with Shariah law. Then again, strange things happen, and not usually by chance. Throughout Dewey’s voluminous writings, two themes recur: that education and learning are interactive processes, which had some basis, and that the school itself is a social institution through which social reform can and should take place, which paved the way for political opportunists.
