Purpose: This study explored approaches for measuring vocabulary among bilingual children with varying levels of proficiency in Spanish and English. Method: One hundred fifteen kindergarten and first-grade Spanish--English-speaking children completed measures of vocabulary and sentence repetition in Spanish and English. Scores were derived from…

In recent years, the use of external proficiency-based tests to measure learners' language ability has increased significantly, in part thanks to the Seal of Biliteracy movement. However, there exists very limited research investigating the influence of such tests and their subsequent outcomes data on teachers' practices. As such, this study…

Morphological knowledge is known to be positively associated with reading ability. However, whether morphological knowledge affects children's learning of new orthographic representations is less clear. Purpose: This study aimed to investigate morphological effects on orthographic learning in English, and whether this effect, if any, is different…

Purpose: This longitudinal study investigated the trajectory of Spanish article accuracy in Spanish-English dual language learners (DLLs) from preschool to first grade, addressing the need for longitudinal data on the variability of Spanish grammatical skills in DLLs in English immersion classrooms. Method: Language sample analysis was conducted…

Spanish-speaking students constitute the largest subgroup of emergent bilingual (EB) students in the United States. Using longitudinal data on a nationally representative sample of Spanish-English EBs, we explore profiles of English reading trajectories and how early individual differences (i.e., early Spanish reading and English oral proficiency)…

This study examined the unique contribution of Home Literacy Environment (HLE), Classroom Literacy Environment (CLE), and parent and teacher expectations to the development of Dutch (L1) and English (L2) vocabulary in children in Dutch-English bilingual primary education. The children (n = 106) were tested on vocabulary in both languages in…

Building on theories of cross linguistic transfer, reading proficiency of Spanish-speaking Emerging Bilinguals may be enhanced by providing tiered instruction through multitiered systems of support. To realize the benefits of this systems-level framework, technically adequate universal screening assessments to support teachers' decision making are…

Providing first language (L1) translations in L2 vocabulary interventions may be beneficial for L2 vocabulary learning. However, in linguistically diverse L2 classrooms, teachers cannot provide L1 translations to all children. Social robots do offer such opportunities, as they can be programmed to speak any combination of languages. This study…

The Comprehensive Test of Phonological Processing, 2nd Edition (CTOPP-2; Wagner et al., 2013) is commonly used in k-12 public schools to assess basic cognitive processing skills foundational for reading achievement. Psychometric support for its use with dual language learners (DLLs), a group representing over 10% of the school-aged population in…

Purpose: The differential diagnosis of developmental language disorder (DLD) in bilingual children represents a unique challenge due to their distributed language exposure and knowledge. The current evidence indicates that dual-language testing yields the most accurate classification of DLD among bilinguals, but there are limited personnel and…

The Matthew effects suggest that children who struggle when learning to read are less likely to read for pleasure later in life compared to children who ease into reading quickly. One aspect of early literacy instruction that might hamper reading progress is learning to read simultaneously in two languages. Despite the long-lasting and widespread…

Purpose: This study examined performance of dual language learners (DLLs) on Spanish- and English-language narrative story retells and unique tells. Transcription and analysis focused on comparisons of common microstructural language sample measures in Spanish and English across tasks. Each language sample measure was evaluated for its possible…

This study aimed to test three competing hypotheses concerning the strength of the cross-language relationship in listening comprehension proficiency in emergent bilinguals: Cummins's developmental linguistic interdependence hypothesis, Proctor, August, Snow, and Barr's interdependence continuum hypothesis, and Goodrich, Lonigan, Kleuver, and…

This study examined the longitudinal prediction of decoding, oral reading fluency (ORF), and bilingual language proficiency (BLP) on student reading comprehension (RC) outcomes in Spanish and in English. Participants were first-grade Latinx students attending bilingual programs. Findings indicated that BLP initial status and gains were significant…

Children with Developmental language disorder (DLD) have particular difficulty learning language despite otherwise general normal development. When school age bilingual children struggle with language, a common question is if the difficulties they present reflect lack of ability or lack of language experience. To address the question of…
