Context: Assessments of baseline equivalency of intervention and control groups, "balance," play a critical role in evaluating educational interventions. The highest What Works Clearinghouse (WWC) of the Institute of Educational Studies (IES) standard for educational studies, "Meets WWC Design Standards Without Reservations,"…

This paper presents evidence confirming the validity of the RD design in the Reading Recovery study by examining the ability of the RD design to replicate the 1st grade results observed in the original i3 RCT focused on short-term impacts. Over 1,800 schools participated in the RD study over all four cohort years. The RD design used cutoff-based…

Beginning in 2002, researchers developed, implemented, and evaluated the efficacy of an English reading intervention for first-grade English learners using multiple randomized control trials (RCTs). As a result of this efficacy work, researchers successfully competed for an IES Goal 4 effectiveness study using the same intervention. Unlike the…

This report presents the SPARK literacy model, an innovative approach developed by Boys & Girls Clubs of Greater Milwaukee, for addressing the literacy needs of low-income and minority schools in Milwaukee. It also presents the results of a two-year randomized control trial evaluation of the SPARK literacy program's impact on reading…

Previous research has suggested that learning to read irregular words depends upon knowledge of a word's meaning and the ability to correct imperfect decoding attempts by reference to the known pronunciations of a word. In an experimental training study, 84 children ages 5-7 years were randomly assigned to an intervention or control group.…

Understanding written language is crucial to academic success in all content areas. Ensuring a strong foundation in the components of written language--that is, the literacy skills of reading, writing, and oral language--is essential if students are to read with understanding and, thus, is a primary goal of early literacy instruction and of the…

This randomized controlled trial in 55 low-performing schools across Florida implemented two literacy interventions--one using a standalone intervention and one using materials embedded in the core reading program. The interventions were delivered daily for 45 minutes for 27 weeks in 2013/14 and 2014/15 in small groups of K-2 students at risk of…

The purpose of this closely aligned conceptual replication study was to investigate the efficacy of a Tier 2 kindergarten mathematics intervention. The replication study differed from the initial randomized controlled trial on three important elements: geographical region, timing of the intervention, and instructional context of the…

For children with the most serious and persistent academic and behavior problems, parent involvement in education, particularly teacher perceptions of involvement, is essential to avert their expected long-term negative outcomes. Despite the widespread interest in and perceived importance of parent involvement in education, however, few…

This article reports the results of a randomized controlled trial that replicated and extended research on the Targeted Reading Intervention (TRI), a professional development program for kindergarten and first-grade teachers in low-wealth rural schools that helps enhance literacy skills of struggling readers. In weekly webcam coaching sessions,…

In this longitudinal study, the cross-language transfer from second language (L2) to first language (L1) was examined among Spanish-speaking English-language learners in an English intervention (Grades 1-3) in the southwest United States. Path analysis revealed statistically significant transfers (ps < 0.05) for the treatment group from English…

The aim of the present study is to examine the effectiveness of combination therapy based on executive function and sensory integration child-centered on ADHD. For this purpose, from among all first, second and third grade primary school students in Shiraz, 40 children were selected. The selected students were randomly assigned in two groups of…

The purpose of this report is to present the results of a two-year randomized control trial evaluation of the SPARK literacy program. SPARK is an early grade literacy program developed by Boys & Girls Clubs of Greater Milwaukee. In 2010, SPARK was awarded an Investing in Innovation (i3) Department of Education grant to further develop the…
