Frederick Jackson Turner was a prominent American Historian who lived during America's Progressive Movement of the early twentieth century. Turner's most seminal piece, The Significance of the Frontier in American History, commonly referred to as The Frontier Thesis, challenged the accepted assumption that American culture stemmed from European ancestors. Turner resisted conventional wisdom that did not take into account the struggles and advances of the pioneers of the West. Turner believed the experiences of the pioneers forced them to adapt and modify their European roots, thus developing a distinct and separate culture from Europe. As a university professor, training a plethora of doctoral students in the field of history, Turner embraced the changes in educational thought of the time; including the importance of lifelong learning and the need to continually re-evaluate previously held beliefs. To Turner, a university professor's priority was to facilitate learning experiences that helped develop students into independent and competent critical thinkers. One way Turner differed from his contemporaries was the way he studied and wrote about history. Turner subscribed to the ideal that all aspects of historical events, incorporating information that set a complete context of the event itself was essential. The historiography Turner employed is considered a standard today. The Progressive Era also brought a wave of reformation in political, social and educational thought. Adult education programs began to develop throughout the nation. Adults for the first time had low cost opportunities outside of collegial studies to expand their professional expertise, literacy skills, and appreciation for art and entertainment. Adult education thinkers also began to systematically research and study ways in which adults best learn. The impetus of this study was to examine Turner's educational and career efforts juxtaposed with adult learning theory, principles and practices as an embedded university elite and active planner and participant of alternative adult education programs. As such, this study investigated Turner as an educator outside the field of adult education, who emulated the principles, practices and value structure of adult learning theory. / Ph. D.
