Literacy instruction for students with significant intellectual disabilities traditionally emphasizes isolated skills instruction focusing on sight words and basic vocabulary. Recent research suggests these students benefit from high-quality instruction that includes comprehension and storybook reading. This study examined the effect of a…

Increasing the accurate use of research-based practices in classrooms is a critical issue. Professional development is one of the most practical ways to provide practicing teachers with training related to research-based practices. This study examined the effects of in-service plus follow-up coaching on first grade teachers' accurate delivery of…

This study examined the effects of instructional intensity on the acquisition of storybook vocabulary in first graders who were at risk of early reading failure. It also measured whether the intervention was effective for closing the vocabulary knowledge gap between students who were at risk and their average-achieving peers. A total of 66…

Patterns of identification for special education services across three cohorts of students in kindergarten through third grade before and after implementation of a schoolwide, three-tier reading prevention model in one large school district are reported. The first cohort of students represents a historical control group that did not participate in…

This study documents the implementation of research-based strategies to minimize the occurrence of reading difficulties in a first-grade population. Three strategies were implemented: (a) A system of progress monitoring was used to assess student progress and skill acquisition; (b) instruction was characterized by high intensity through the use of…

This study sought to examine the effects of Tier 2 intervention in a multitiered model on the performance of first- and second-grade students who were identified as having mathematics difficulties. A regression discontinuity design was utilized. Participants included 126 (Tier 2, n = 26) first graders and 140 (Tier 2, n = 25) second graders. Tier…

This study examined the efficacy of a paraprofessional-led supplemental early intervention for first-grade students with poor early literacy skills and behavioral concerns. The goal was to determine if (a) the relatively brief intervention was effective in improving phonological skills, and (b) improvements in academic skills would be accompanied…
