This dissertation draws on both qualitative and quantitative approaches to investigate the linguistic practices of teachers and children who are learning Mandarin Chinese as a Heritage Language (CHL) in two dual immersion preschools in California. CHL children have been interpreted as novice members in local speech communities who actively explore…

California is on the cusp of implementing universal preschool--a step that could help level the playing eld for young children. Over the next few years, all four-year-olds will become eligible for Transitional Kindergarten (TK), which has been part of the state's early learning programs since 2012. In this report, the authors examine the…

Purpose: Emergent bilinguals (EBs) from Spanish-speaking households are a sizable and quickly growing segment of the preschool population in the United States. However, there is limited research on the provision of opportunities for EBs to engage in language-rich classroom discussion, particularly in English-dominant contexts where most EBs attend…

This brief shares findings from a formative evaluation of Early Childhood Language Development Institute (ECLDI) programs at two early learning sites. At each, ECLDI provided training and support to program leadership, teaching teams, and families. The brief provides a summary of the report and discusses lessons for the field. [This three-part…

Dual language learners make up an increasing share of preschool students, but they often perform worse than monolingual students on assessments measuring school achievement. This study compares Head Start classrooms implementing either the dual language model or the English with home language support model. The author examines how the models…

This research compared the relative impact of different preschool activities on the development of bilingual students' English-language skills. The study investigated whether bilingual preschool children would engage more, and use more of their second language (English), during free-play (non-academic) versus teacher-structured (academic)…

Significant differences in language and self-regulation skills exist among children when they enter formal schooling. Contributing to these language differences is a growing population of dual language learners (DLLs) in the United States. Given evidence linking self-regulatory processes and language development, this study explored bidirectional…

The population of Spanish-speaking preschoolers in the United States continues to increase and there is a significant need to develop psychometrically sound early language and literacy screening measures to accurately capture children's ability in Spanish. In this paper, we describe the innovative design and calibration process of the new…
