Development is a keyword in the vocabulary of teacher education research. Keywords are high-frequency words and phrases that while bringing people together in conversation are nonetheless sites of significant contestation in the field. At its most basic level, in the phrase “teacher development,” development can refer either to the development of the teacher (personal-professional formation) or to the development of the practice (teaching). Adopting descriptive categories from literacy research to delineate “simple” and “complex” views on the underlying questions of development, it becomes clear that, within such a dichotomous construction, “simple” approaches are insufficient either to describe or to plan for becoming a teacher and experiencing growth in professional practice. Underpinning these “simple” and “complex” views in the research on teacher education, divergent perspectives on formation (e.g., the “natural born teacher” vs. becoming through struggling with an identity) and learning (e.g., high-intensity training in “moves” vs. complex trajectories of participation in social practices and the growth of critical reflexivity). Thus, in the research literature, it is possible to discern critical-humanistic and also techno-rationalist clusters of meaning: optimistic yet expansive understandings of learning and change alongside well-intentioned oversimplifications of inherently contingent and uncertain situations. Navigating these clusters is consequential for how the work of teaching and of educating teachers can be understood. Indeed, the vocabulary of teacher education research needs to be examined much more closely so that, by interrogating keywords such as development, new spaces for a more critical deliberation of becoming a teacher and for more transformative practices of both teaching and teacher education can be stimulated.
