The papers in this monograph review the literature and summarize recent research findings on factors affecting educational change in the public schools. The authors also report the reactions of several principals who have attempted to implement significant educational innovation in their schools. In the opening chapter, Kenneth A. Tye uses a systems model to discuss equilibrium, resistance, and strategies that facilitate change. Next, Mary M. Bentzen discusses the demands that accompany the principal's role, the conflicts he faces, and how these demands and conflicts might be channeled and resolved. Robert L. Sinclair examines the expression, requirements, and determinants of leadership behavior. Jerrold M. Novotney's chapter describes methods for achieving optimum staff involvement and cooperation in change efforts. In the final chapter, Donald A. Myers discusses the roles of the principal and of his teachers in the decision-making process. Lillian K. Spitzer prepared the annotated bibliography on change which contains 65 recent citations.
