This study purposed to examine the trends of research on Vygotsky’s scaffolding theory in early childhood education studies in Korea. For this purpose, we analyzed 68 research outcomes including master’s and doctoral theses on scaffolding in the area of early childhood education published by general graduate schools in Korea and academic dissertations registered at Korea Research Foundation, and through the analysis, reviewed research trends in Korea comprehensively and suggested future research tasks. According to the results of analysis, in the domestic area of early childhood education, the concept of scaffolding has been changed variously depending on interpretation and approach due to its metaphoric characteristic. Each researcher defined and studied the concept of scaffolding based on different criteria, and more of related studies tested the educational effects of scaffolding and looked for efficient methods through the comparative analysis of scaffolding types. However, these studies had limitations in that they simplified scaffolding into some benefits, support system or teaching strategy rather than explaining directly the characteristics of reciprocal scaffolding suitable for young children, that the concept of scaffolding was limited to verbal types and behavioral expressions, and that teachers’ roles for reciprocal scaffolding were not suggested clearly and therefore they might be misunderstood. For future tasks to solve these problems, this study suggested research for clarifying teachers’ roles for reciprocal scaffolding, for analyzing the context of scaffolding in multi?dimensional relations, and for the use of qualitative research methods.
