This study investigated the relationship among home language use, parents' beliefs about dual language development, and Spanish-speaking children's vocabulary knowledge. Parents (n = 162) completed a questionnaire about their home language use and beliefs about dual language development, and elementary-age children (N = 190) -- Kindergarten…

This study contrasted face-to-face and remote coaching models using an empirically-based professional development model, The Early Education model (TEEM). Child care teachers (n = 174) were randomly assigned to 1 of 3 conditions: remote coaching (n = 59), face-to-face coaching (n = 66), and business-as-usual (n = 49). This study examined…

Purpose: Despite the unprecedented growth of Spanish-English dual language learners (DLLs) in new destination states--where DLLs have not been historically served--empirical understanding of their language and literacy skills is scant. Drawing on scientific understandings of bilingual language acquisition, we compare monolingually scored and…

Given the importance of math in today's society, it is critical that children who are at risk for math difficulty are identified early. We developed and validated a prekindergarten math subtest (i.e., CIRCLE Progress Monitoring [CPM] Math Subtest). This teacher-completed measure evaluates domains considered important for later math development.…

Fingerspelling and its relationship with literacy skills among deaf and hard of hearing children who use American Sign Language is an increasingly popular research topic. However, there is limited research on whether reading interventions that systematically include fingerspelling are more effective for improving literacy skills than reading…

A tenet of the Multi-Tiered System of Supports (MTSS) is that even evidence-based interventions will not be effective with all children. We examined preschool children's response to a supplemental literacy intervention ("Story Friends") in two classrooms. Children with weak vocabulary skills were identified and received the intervention.…

Preschool teachers from a high-poverty, urban school district were trained to implement Story Talk, a book reading intervention designed to increase children's vocabulary and language development using supportive materials and strategic individualized coaching. Thirty-five teachers were randomly assigned by site to the intervention (20) or the…

Children from low-income and ethnic minority backgrounds have demonstrated substantially lower levels of math achievement than their middle class majority peers for decades. The present study addressed two research questions: (1) when used as a supplement to typical classroom instruction and in isolation from the larger curriculum, does Building…

This study evaluated Earobics Step 1, a commercial literacy program, and examined whether impact varied with children's school readiness and classroom instruction. Participants included 247 kindergarteners from 37 classrooms in nine Title 1 schools. Children were randomly assigned to receive 21 weeks of computerized instruction with Earobics or…

In experimental studies, researchers are often interested in secondary research questions that explore important aspects of main findings, such as whether or not program effects vary according to the level of fidelity in which the program has been implemented; or according to the dosage received by individuals participated in the program. In this…

Learning-related behaviors are important for school success. Socioeconomic disadvantage confers risk for less adaptive learning-related behaviors at school entry, yet substantial variability in school readiness exists within socioeconomically disadvantaged populations. Investigation of neurophysiological systems associated with learning-related…

Research Findings: This study examined processes of change associated with the positive preschool and kindergarten outcomes of children who received the Head Start REDI (REsearch-based, Developmentally Informed) intervention compared to usual practice Head Start. Using data from a large-scale randomized controlled trial ("N" = 356…

"Tools of the Mind" is an early childhood curriculum for preschool and kindergarten children, designed to foster children's executive function through development of self-regulation, working memory, and cognitive flexibility. Activities emphasize both executive functioning and academic skills. One study of "Tools of the Mind"…
