This study examined the effects of a supplemental early reading intervention on the beginning literacy skills of 12 kindergarten/first-grade urban English language learners (ELLs). The Early Reading Intervention (ERI; Simmons & Kame'enui, 2003) was the instructional intervention used with all students. A multiple-baseline design across students was used to investigate the effects of the instruction on phoneme segmentation fluency (PSF) and nonsense word fluency (NWF), as measured by the Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2002). Data analyses showed that all students increased in the number of phonemes segmented and the number of letter sounds produced correctly. Gains were commensurate with the amount of instruction received. (Contains 2 figures and 3 tables.)
