This study aimed to explore the evolution of prospective teachers’ beliefs about children’s rights, children, and preschool teachers through metaphor construction. The participants selected for the study were 6 prospective teachers enrolling in the child welfare course at a university in Seoul. During one semester, participants engaged in the construction of personal metaphors, analysis of changing beliefs about children’s rights, and metaphor development and modification. The updated metaphor activity was carried out following the university-based academic experiences and field-based experiences. Metaphor analysis was proceeded with a qualitative inquiry approach and those were transcribing, memoing, open coding, focused coding and developing themes. The analysis revealed that, first, in participants’ initial metaphors at the beginning of the semester, early childhood prospective teachers described the ambiguity of children’s rights and teacher-child relationships to be mutually related to the characteristics of children who are subject to protection and of teachers who fulfill their obligations. In this light, three main themes emerged: ‘children’s right as invisibility’, ‘children as diversity and universality’, and ‘teachers whose obligations are emphasized.’ Second, in participants’ updated metaphors at the end of the semester, prospective teachers’ beliefs about children’ rights were changed and expanded under the themes of ‘rights requiring social efforts’, ‘children with rights as social agents’, and ‘teachers with rights and duties as a social being.’ The results of this study may help to facilitate early childhood prospective teachers’ beliefs construction about children’s rights, and to suggest the potential value of metaphor work for informing teacher education and professional development.
