Overview
The goal of the proposed study is to directly and rigorously address current scientific controversy about phonological awareness intervention content and timing for prekindergarten and kindergarten children. Using an experimental design, we will compare the relative impact of phonological sensitivity + phonemic awareness intervention versus phonemic awareness intervention on children's phonemic awareness and later reading and spelling abilities. We expect that both types of intervention will lead to impacts beyond business-as-usual instruction but do not have directional hypotheses as to which type of intervention will be most effective. Also, we will determine the relative efficacy of intervening in prekindergarten versus kindergarten, examine child characteristics that might moderate effects, and explore whether a transition point can be identified as to when phonemic awareness intervention may be most effective. Ultimately, our findings will help optimize early phonological awareness instruction.
