This study guided by Vygotsky's Zone of Proximal Development (ZPD) theory explored the perception of pre-service teachers about the application of the ZPD in the classroom. Five participants, all junior students, were purposefully selected from a university in the southern region of the United States to participate in the study. Open-ended interview questions were designed from a review of the literature regarding the effectiveness of Vygotsky's ZPD in the classroom. Axial coding was used to analyze the data for the final research report. A major finding from the study is that Vygotsky's ZPD is recognized by Educator Preparatory Providers (EPPS) as a major instructional approach used to promote student achievement and that some pre-educator candidates perceive problems implementing this innovative form of teaching social studies in the early childhood classroom. Another significant finding from the study is that it extends our knowledge about the application of Vygotsky's ZPD in the early childhood social studies classroom. Implications for early childhood teacher preparation and future research are considered in the paper.
