| Abstract: | Research Findings: Multitiered instructional frameworks are becoming a recommended approach for enhancing prevention and intervention efforts targeting early literacy and language skills. However, few studies to date have studied the feasibility of tiered oral language interventions before kindergarten; therefore, this pilot study explored the effectiveness of such an approach in prekindergarten. Teachers in 39 classrooms were randomly assigned to an experimental or comparison condition that contrasted the implementation of an intervention that had both Tier 1 (whole group) and Tier 2 (small group for at-risk children) components. The pilot study included only 4 weeks of teacher-administered intervention. Despite this short duration, a significant and large effect size (d = .81) was observed for the experimental group on a receptive target vocabulary assessment. No significant changes were found on measures of vocabulary fluency, expressive target vocabulary, or listening comprehension. It is important to note that teachers’ fidelity in implementing the intervention as designed was a significant predictor of children's learning. Practice or Policy: These findings suggest the potential promise of the multitiered instructional framework, especially when teachers can be supported in ways that ensure adequate fidelity of implementation. Implications for use in prekindergarten response-to-intervention models are discussed. |
