Effects of a Peer-Mediated Program on Reading Skill Acquisition for Two-Way Bilingual First-Grade Classrooms

The purpose of this study was to examine the effect of a supplemental peer-mediated reading program on reading achievement of first graders (N = 76) in a two-way bilingual immersion (TWBI) program. Nearly 80% of students were Hispanic; of these, 24 were identified as English language learners (ELLs). Classrooms were randomly assigned to peer-assisted learning strategies (PALS) or contrast condition. PALS students participated in a 30-hour peer-mediated early literacy intervention that was conducted three times a week. Results showed statistically significant differences, with large effect sizes favoring PALS on phoneme segmentation fluency, nonsense word fluency, and oral reading fluency. Additionally, disaggregated results analyzed by subgroups (ELLs and English proficient) revealed a differential pattern in response to intervention. Implications of findings in relation to research and practice are discussed.
