This proposed Klingenstein project is a design for a professional development program for the Upper School faculty (N=41) at Renbrook School, an independent school, in West Hartford (Connecticut). It is also an attempt to use the theories of adult learning, human cognition, educational leadership, and definitions of school culture and change to create a prototypical orientation to effective and long-lasting staff development efforts in independent schools. Several concrete goals and products are attached to the design. For example, teachers will collect personal and scholarly pieces for a professional portfolio during the course of the year; some content choices and requirements are delineated. Also, in order to fit such a plan into already loaded school days, several official professional development presentations are scheduled to occur within regular divisional faculty meetings at monthly intervals. An annotated bibliography, a workbook of activities to promote collegial discourse, and a collection of four resource volumes provide print support for this undertaking. The final outcome of this plan will be a teacher-constructed curriculum of "learning strategies" overlaying the full range of upper school content area courses, to be in place within 2 years after starting the project.
