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…

The main objective of this study was to evaluate the efficacy of a Tier 2 intervention within the context of the Response to Intervention (RtI) model implemented by Spanish first- to second-grade primary school teachers to improve at-risk students' transcription skills. Teachers were instructed in the administration of a writing curriculum-based…

Prior research suggests that Spanish-speaking Dual Language Learners (DLLs)--young children who must master two languages simultaneously, their home language and English (Espinosa, 2013)--differentially benefit from quality Early Childhood Education (ECE), and in particular from Head Start, compared with children of other subgroups and…

This study examined the impact of two different interventions: Phonological Awareness PA-only versus PA, vocabulary, and Morphological Awareness (MA) on Spanish-speaking kindergarteners' language and literacy skills. We took measures on PA, vocabulary, letter-name and sound knowledge, and MA. Children in the comprehensive intervention condition…

Research Findings: Using a nationally representative sample of Head Start recipients, this study compared Head Start classroom contexts and English language and literacy skill trajectories for Spanish-speaking dual-language learners (DLLs) and English speakers from preschool through kindergarten. It also examined whether Head Start classroom…

Purpose: Early Interventions in Reading (Vaughn et al., 2006), the only literacy intervention with demonstrated effectiveness for U.S. dual language learners, was enhanced to support the development of oral language (vocabulary, grammar, and narrative) and literacy, which we refer to as "Language and Literacy Together." The primary focus…

The Houston Independent School District (HISD) has provided free prekindergarten classes for eligible Houston area four-year old students since the 1985-1986 school year. HISD offers full-day prekindergarten programs to all eligible students within its attendance boundaries. HISD collaborates with four federally-funded Head Start agencies that…

The purpose of this study was to evaluate the efficacy of the Home Instruction for Parents of Preschool Youngsters program when implemented within Head Start programs by measuring children's language proficiency scores. Participants were kindergarteners concurrently enrolled in both a Head Start program and the Home Instruction for Parents of…

This brief focuses on Head Start children's developmental progress and kindergarten experiences, drawing on data from the 2009 cohort of the Head Start Family and Child Experiences Survey (FACES 2009). The focal population is children who entered Head Start for the first time in fall 2009, completed one or two years of the program, and were…

This study hypothesized that HISD prekindergarten participation consistently correlated with better educational outcomes for students. Taking into account students' age differences through kindergarten enrollment, propensity score matching controlled for students' background characteristics. Three cohorts of students in this study were eligible or…

Dyslexia is a specific learning disability in reading and writing, which requires adequate early intervention to prevent future school failure. We describe the diagnostic assessment of a 7-year-old boy labelled "dyslexic", the evaluation of his family, social, medical, developmental, and academic status as a preliminary for the design…

We investigated the latent factor structure of the "Phonological Awareness Literacy Screening for Kindergarteners" in Spanish ("PALS español K"). Participants included 590 Spanish-speaking, public-school kindergarteners from five states. Three theoretically-guided factor structures were measured and tested with one half of our…
