This study compared the effects of Tier 2 reading interventions that operated in response-to-intervention contexts. Kindergarten children (N = 90) who were identified as at risk for reading difficulties were stratified by school and randomly assigned to receive (a) Early Reading Intervention (ERI; Pearson/Scott Foresman, 2004) modified in response…

This report describes a cluster randomized control trial (RCT) intervention study of the effectiveness of the ABRACADABRA (ABRA) Web-based literacy system using a classroom-level RCT intervention with 1,067 children in 74 kindergarten and Grade 1 or Grade 1/2 classrooms across Canada. The authors closely followed the CONSORT criteria for executing…

Reading fluency is a critical component of effective reading instruction for students of early elementary age. However, national data suggest that 40% of U.S. fourth-grade students are nonfluent readers. Implementing evidence-based, time-efficient, and procedurally standardized instructional strategies may help address this problem. This study…

The purpose of this study was to evaluate the efficacy of a classroom-teacher-delivered reading intervention for struggling readers called the Targeted Reading Intervention (TRI), designed particularly for kindergarten and first-grade teachers and their struggling students in rural, low-wealth communities. The TRI was delivered via an innovative…

The relative effectiveness of two computer-assisted instructional programs designed to provide instruction and practice in foundational reading skills was examined. First-grade students at risk for reading disabilities received approximately 80 h of small-group instruction in four 50-min sessions per week from October through May. Approximately…

This intervention study tested whether invented spelling plays a causal role in learning to read. Three groups of kindergarten children (mean age = 5 years 7 months) participated in a 4-week intervention. Children in the invented-spelling group spelled words as best they could and received developmentally appropriate feedback. Children in the 2…

The effectiveness study examined a supplemental reading intervention that may be appropriate as one component of a response-to-intervention (RTI) system. First-grade students in 31 schools who were at risk for reading difficulties were randomly assigned to receive Responsive Reading Instruction (RRI; Denton, 2001; Denton & Hocker, 2006; n =…

Successful implementation of evidence-based educational practices at scale is of great importance but has presented significant challenges. In this article, the authors address the following questions: How does the level of on-site technical assistance affect student outcomes? Do teachers' fidelity of treatment implementation and their perceptions…

This study investigated the effects of three instructional conditions on precursors to successful reading for Spanish-speaking English language learners (ELL). The study was conducted using a randomized, alternate treatment control group design specifically targeting phonological awareness (PA) listening comprehension (LC), and decoding in a…

To help states and districts make informed decisions about the professional development (PD) they implement to improve reading instruction, the U.S. Department of Education commissioned the Early Reading PD Interventions Study to examine the impact of two research-based PD interventions for reading instruction: (1) a content-focused teacher…

In this article, the authors report achievement outcomes of a multisite cluster randomized field trial of Open Court Reading 2005 (OCR), a K-6 literacy curriculum published by SRA/McGraw-Hill. The participants are 49 first-grade through fifth-grade classrooms from predominantly minority and poor contexts across the nation. Blocking by grade level…

The No Child Left Behind (NCLB) Act of 2001 created the Early Reading First (ERF) program to enhance teacher practices, instructional content, and classroom environments in preschools and to help ensure that young children start school with the skills needed for academic success. This report to Congress describes the impacts of the Early Reading…

The evaluation of the Voyager Universal Literacy System[R] was designed to provide a rigorous assessment of the effectiveness of the program with beginning readers. Using a quasi-experimental design, researchers conducted a systematic evaluation of changes in 398 kindergarten students' command of early reading skills in 4 Voyager and 4 comparison…

A variety of preschool curricula is available and in widespread use, however, there is a lack of evidence from rigorous evaluations regarding the effects of these curricula on children's school readiness. The lack of such information is important as early childhood center-based programs have been a major, sometimes the sole, component of a number…

Background: The Waterford Early Reading Program (WERP), a technology-based program for early elementary grades, was provided through Arizona all day kindergarten funds to kindergarten students in 15 Title I elementary schools in the Tucson Unified School District (TUSD) in the 2005-06 school year. The purpose of this study is to evaluate the…
