This narrative inquiry into teacher development focuses on my relationship with teacher-participant Bob Fitzgerald over four years of classroom observation and collaboration. I employed participant observation, dialogue with my participant, personal reflections and detailed field texts to develop an understanding of the contexts in which teachers work and teacher development as a relational process.The first part, a narrative account of my field observations, begins with an examination of the three-dimensional educational landscape of Lippincott School followed by an exploration of Bob's personal professional knowledge. Then I examine the development of our relationship as I helped Bob respond to the principal's criticisms. This section concludes with an outline of the long-term impact on Bob's practice.The initial purpose was to develop a narrative understanding of teacher knowledge and development by examining Bob's personal professional knowledge and professional knowledge landscape. Later, my purpose shifted to examining the "helping" relationship (Rogers, 1961) Bob and I developed in response to a crisis. Building on Clandinin and Connelly's "teacher as curriculum maker" (1992) and Hollingsworth, Dybdahl and Minarik's "relational knowing" (1993), I puzzled over the relational characteristics that prompted our individual and shared professional development.In the second part, these experiences are interpreted through examinations of Bob's personal practical knowledge, the principal's supervision, and our helping relationship. While all three elements were important, our helping relationship is identified as critical in directing Bob's professional development in a positive direction. Seven characteristics of our teacher development relationship are identified and examined.The final part begins with a consideration of how the relational approach to teacher development that emerged from my work with Bob has informed my practice as a teacher educator. I conclude by considering how relational teacher development might enrich teacher knowledge and development in a range of professional contexts.
