Development of professional knowledge in learning to teach elementary science

The purpose of this research was to understand how preservice elementary teacher experiences within the context of reflective science teacher education influence the development of professional knowledge. We conducted a case analysis to investigate one preservice teacher's beliefs about science teaching and learning, identify the tensions with which she grappled in learning to teach elementary science, understand the frames from which she identified problems of practice, and discern how her experiences played a role in framing and reframing problems of practice. The teacher, Barbara, encountered tensions in thinking about science teaching and learning as a result of inconsistencies between her vision of science teaching and her practice. Confronting these tensions between ideals and realities prompted Barbara to rethink the connections between her classroom actions and students' learning and create new perspectives for viewing her practice. Through reframing, she was able to consider and begin implementing alternative practices more resonant with her beliefs. Barbara's case illustrates the value of understanding prospective teachers' beliefs, their experiences, and the relationship between beliefs and classroom actions. Furthermore, the findings underscore the significance of offering reflective experience as professionals early in the careers of prospective teachers. © 1999 John Wiley & Sons, Inc.
