Implementation fidelity is often thought of as a necessary condition to achieve internal validity and as having a relation to student outcomes. This relation is increasingly modeled; we reviewed reading intervention studies for students in pre-K-12 in which measures of implementation fidelity were included in final data analysis. A systematic…

Classroom reading instruction is the foundation of Multi-Tiered Systems of Support in Reading (MTSS-R) and the focus of many state reading reforms, initiatives, and policies. The purpose of this study was to evaluate whether comprehensive and coordinated Tier 1 core reading instruction was associated with higher early reading outcomes of students…

Core reading programs have a tremendous influence over reading instruction in the United States. Federal policies such as Reading First put increasing pressure on schools to implement a core reading program. While core reading programs contain a wide variety of suggested strategies and activities, they may not provide sufficient text or volume of…

This study examined the impact of Oregon Reading First on student reading outcomes. Outcomes in schools that began Reading First implementation in 2003-2004 (Cohort A) were compared to outcomes in schools that began Reading First implementation in 2005-2006 (Cohort B). The primary hypothesis, that experienced Cohort A schools would outperform…

This study used a randomized experimental design to examine the relationship between teacher-student ratio and literacy learning outcomes for experienced intervention teachers working with the most at-risk first-grade students. Eighty-five Reading Recovery teachers, working with 170 students, each taught in a 1:1 and a small-group instructional…

Examined first-year results of the Success for All (SFA) program, designed to bring every student to grade level in reading by third grade. Found that SFA benefits were most significant at the kindergarten level; teachers were highly accepting of the program; and the program's strengths included cooperative learning, regrouping, tutoring, early…

Examined six aspects of vocabulary instruction given to fourth and sixth graders prior to reading in two basal reading series. Found that words targeted for instruction were already known; instruction in the two series differed markedly; much of the instruction was not sufficient to improve comprehension; and instruction was not necessarily suited…
