Vocabulary plays a critical role in later reading achievement of emergent bilingual children (EBC) who are learning two languages. Given emerging vocabulary intervention research for EBC, we synthesize studies on vocabulary interventions designed for preschool and kindergarten EBC to provide the cumulative knowledge on the following dimensions:…

This secondary analysis study examined patterns, predictors, and outcomes of dual language learners' (DLLs') development in Spanish and English. Research Findings: Latent profile analysis identified three groups of DLLs: Balanced Bilinguals (54%), English-Dominant Bilinguals (25%), and Spanish-Dominant Bilinguals (21%).

Georgia's Pre-K Longitudinal Study followed a statewide sample of 1,169 children who attended Georgia's Pre-K Program in 2013-14 through their 4th grade year in 2018-19. The study was conducted by researchers at the Frank Porter Graham (FPG) Child Development Institute at the University of North Carolina at Chapel Hill. The following summary…

The purpose of this study was to explore the use of code-switching in the narratives of dual-language Latino preschoolers, specifically by examining its incidence, types, functions, and grammaticality. Previous work has investigated code-switching in younger children and in older children and adults, but relatively little work has investigated…

Young English learners (ELs) whose home language is Spanish continue to lag behind in several school readiness areas including language and literacy skills in spite of their strong social skills, which are positively related to language and literacy. The purpose of this article is to identify challenges that preschool Spanish speaking ELs face,…

The purpose of this evaluation study was to examine children's longitudinal academic and social outcomes associated with attendance in Georgia's Pre-K Program and to examine the quality of the classrooms attended. This report covers pre-k to 4th grade outcomes collected between the 2013-2014 and 2018-2019 school years as well as a sub-study…

Cross-linguistically, monolingual children produce target-like inflected verbs much earlier than they can reliably distinguish between singular and plural subject-verb agreement morphology in comprehension (i.e. Johnson, V., J. de Villiers, and H. Seymour. 2005. "Agreement Without Understanding? The Case of Third Person Singular /s/."…

Although the COVID-19 pandemic has profoundly affected K-12 education worldwide, Peru has faced particularly unique challenges. A combination of quarantine requirements and unequal access to remote learning technology led to the creation of a series of multimodal programs by Peru's Ministry of Education under the umbrella title Aprendo en Casa [I…

This longitudinal qualitative study examined the progression in the levels of writing conceptualizations in Spanish and English of 20 simultaneous bilingual children from PreK-K.

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…

Children from lower socioeconomic (SES) backgrounds tend to be at-risk for executive function (EF) impairments by the time they are in preschool, placing them at an early disadvantage for academic success. The present study examined the potentially protective role of bilingual experience on the development of inhibitory control (IC) in 1146 Head…

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…

English-Spanish cognates are words that possess identical or nearly identical spellings and meanings in both English and Spanish as a result of being derived mainly from Latin and Greek. Of major importance is the fact that many of the more than 20,000 cognates in English are academic vocabulary words, terms essential for comprehending school…

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…
