The purpose of this study is to explore early childhood pre-service teachers’ perspectives on child, teacher, and assessment and highlight changes in their perspectives as those are revealed through their metaphor-narrative construction and the modification. The research participants are 13 pre-service teachers enrolling in the early childhood assessment course at a Southwestern university in the United States. Pre-service teachers participated in the continuos process of constructing, sharing and reflecting upon their child assessment metaphor throughout the semester. Two metaphor-narratives pre-service teachers submitted at the beginning and at the end of the semester and their reflection paper were the main sources of the qualitative data for this study. The results show that, in their first metaphors, pre-service teachers represented interrelated images of child, teacher and assessment, which could be summarized as the themes of ‘different but same children’, ‘objectification of children vs. teachers as a homeogenous group’, and ‘positivism.’ In the modification of metaphors at the end of the semester, pre-service teachers began to raise questions about the sources of knowledge, justification of the knowing process, and the certainty of knowledge. To account for these changes in pre-service teachers’ epistemological beliefs, the following three themes were discussed: ‘complex and unpredictable children’, ‘different teachers with standardized work’, and ‘child assessment: subjectivity.’ This study provides implications for teacher education program in helping pre-service teachers’ self-understanding and re-construction of personal and practical knowledge concerning the child assessment. This study also contributes to re-assessing the value of metaphor not just as a research tool for investigating teachers’ perception but also for an active pedagogical tool to guide teachers’ reflection.
