Vocabulary knowledge of preschool children is a key factor in predicting literacy success in elementary school (Hammer, Farkas, & Maczuga, 2010). However, few deliberate attempts to teach basic concept vocabulary have been studied (Bowers & Schwarz, 2013; Wilson, 2004). The purpose of this research is to determine if large group explicit instruction with interactive activities of specific basic concept vocabulary will increase preschool children\u27s understanding of basic concept terms when measured by a standardized basic concept assessment. This research will also assess the validity of a basic concept-curriculum based measure (BC-CBM) as an efficient tool to monitor a child\u27s understanding of basic concept vocabulary over time. There were 30 preschool children (M age=53.8 months) who participated in this experiment. Results demonstrated the standardized assessment and BC-BM raw scores improved through intervention. Further research is supported to evaluate the BC-CBM on a larger scale and control for more factors, which influence vocabulary development in children.
