Assessing the Effects of the McGraw Hill Phonemic Awareness Program with Preschool Children with Developmental Delays: A Case Study

This study assessed the effects of McGraw Hill Phonemic Awareness on the phonemic awareness skills of 5 preschool children with developmental delays. The children received 60 of the 110 lessons included in this program over 5 months. They were pre- and posttested using the kindergarten level Initial Sound Fluency and Phoneme Segmentation Fluency subtests of the Dynamic Indicators of Basic Early Literacy Skills (DIBELS). Results showed average increases of 16.6 initial sounds per minute and 27 phonemes per minute. Implications for future research are discussed.
