We present findings across three randomized trials of "Descubriendo la Lectura" (DLL), an intervention designed to improve literacy skills of Spanish-speaking first graders struggling with reading. DLL is a one-to-one Spanish-language literacy program lasting 12-20 weeks offered to a school's lowest performing emerging bilingual first…

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…

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…

This randomized controlled trial in 55 low-performing schools across Florida compared 2 early literacy interventions--1 using stand-alone materials and 1 using materials embedded in the existing core reading/language arts program. A total of 3,447 students who were below the 30th percentile in vocabulary and reading-related skills participated in…

Using a low inference observation instrument, we investigated the effect of an ongoing, intensive, and structured virtual professional development [VPD] on fidelity of implementation across conditions in a randomized control trial validation study implemented in seven Texas school districts. The observations were collected three time in the…

This study explores preliminary results from a pedagogical intervention designed to improve instruction for all students, particularly emergent bilinguals in the United States (or English language learners). The study is part of a larger efficacy randomized controlled trial (RCT) of the Instructional Conversation (IC) pedagogy for improving the…

The purpose of this study was to test the promise of the NumberShire Level 1 Gaming Intervention (NS1) to accelerate math learning for first-grade students with or at risk for math difficulties. The NS1 intervention was developed through the Institute of Education Sciences, Small Business Innovation Research Program (Gause, Fien, Baker, &…

The Instructional Conversation (IC) is a complete classroom pedagogy that focuses on teaching through small-group dialogue with students allowing responsive instruction for each student. The IC is anchored by cognitive-developmental theory and by four decades of multi-method quasi-experimental studies. This study describes the first research of an…

This study examines the effect of 30 min of small group explicit instruction on reading outcomes for first-grade Spanish-speaking English learners (ELs) at risk of reading difficulties. Participants were 78 ELs from seven schools who were receiving Spanish only, or Spanish and English, whole group reading instruction in first grade. Students were…

Head Start is the largest publicly funded preschool program in the U.S., and one of its primary goals is to improve the school readiness of low-income children. As has been widely reported, the first randomized trial of Head Start in the program's history found some evidence that it is achieving this goal. Receiving one year of Head Start had…
