Abstract

This study examined the effects of a parent-implemented intervention on preschool children's development of letter-naming and phonological awareness skills. Six parent-child dyads with children enrolled in a Head Start Program in West Central Florida were selected to participate in the study. A multiple baseline across participants design was used to evaluate the impact of an intervention package that included activities focusing on: (1) using mnemonics to learn letter names and (2) developing phonological awareness of the onsets of words through parent questioning and feedback. Phonological awareness development was measured using the Dynamic Indicators of Basic Early Literacy Skills First Sound Fluency (DIBELS-FSF) and letter-naming ability was measured using the DIBELS Letter Knowledge (DIBELS-LK) probes. Results showed that five of the six students responded favorably to the intervention, increasing their growth rate on at least one of the two measures. The final child showed little change in trends across the phases. Additionally, data was collected regarding intervention integrity of intervention implementation as well as social validity, or the acceptance and usefulness, of the intervention. Intervention integrity data revealed that the majority of parents completed the intervention with high levels of fidelity, although variability across parents was noted. Social validity data indicated that the parents found the program helpful and effective. Implications for research and practice are discussed.
