We examined the development of 3 executive function (EF) components--inhibition, updating, and task shifting--over time in monolingual and bilingual school-age children. We tested 41 monolingual and 41 simultaneous bilingual typically developing children (ages 8-12) on nonverbal tasks measuring inhibition (the Flanker task), updating (the Corsi…

Purpose: Current understanding about the effect of first language (L1) background on morphological awareness (MA) development in those who are bilingual is largely limited to school-aged second-language learners. This study examined the development of MA in bilingual Mandarin-English (ManEngBi) and Spanish-English (SpaEngBi) children ages 4 to 7…

Purpose: This article aims to describe how exemplar variability can manipulate the word learning environment to maximize within- and cross-language generalization in Spanish--English bilinguals. Furthermore, we examined sources of individual variability that predicted word learning. Method: Nineteen Spanish--English bilingual children participated…

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/."…

The number of English language learners (ELLs) in early childhood education (ECE) continues to increase, particularly with students whose first language (L1) is Spanish. Recent studies have shown the connection between teachers' self-efficacy and student achievement, but very few specifically address early childhood education teachers'…

This article offers a critical appraisal of "educación intercultural bilingüe," an educational model with at least five decades of implementation. When this term was coined, Indigenous populations were mostly monolingual and their settlements mostly rural and distant from the seats of cultural hegemony and power. The situation is now…

Constraints on linguistic variation are consistent across adult speakers, yielding probabilistic and systematic patterns. Yet, little is known about the development of such patterns during childhood. This study investigates Spanish subject pronoun expression in naturalistic data from 154 monolingual children in Mexico, divided into four age…

Previous analyses of the Spanish deictic verbs "venir" "to come", "ir" "to go", traer "to bring" and "llevar" "to take" have drawn upon Fillmore's (1975) series of lectures on deixis in noting that speakers of Spanish forbid the use of the verbs "venir" and…

This research investigates the effectiveness of using a child's first language (L1), specifically Spanish, with Audio Prompting (AP) delivered via a tablet computer by monolingual English-speaking clinicians to enhance vocabulary growth in the L1 and second language (L2) of children who are English Learners (ELs). Outcomes of vocabulary…

Purpose: This study examines the effects of the levels of speech practice on fast mapping in monolingual and bilingual speakers. Method: Participants were 30 English-speaking monolingual and 30 Spanish-English bilingual young adults. Each participant was randomly assigned to 1 of 3 practice conditions prior to the fast-mapping task: (a) intensive…

Purpose: The acceptable noise level (ANL) measure has gained much research/clinical interest in recent years. The present study examined how the characteristics of the speech signal and the babble used in the measure may affect the ANL in listeners with different native languages. Method: Fifteen English monolingual, 16 Russian-English bilingual,…

The unique relation of language use (i.e., output) to language growth was investigated for forty-seven 30-month-old Spanish-English bilingual children (27 girls, 20 boys) whose choices of which language to speak resulted in their levels of English output differing from their levels of English input. English expressive vocabularies and receptive…

This article reports on a case study of a kindergarten, monolingual teacher and how she used Spanish, the home language of her Latino/a students who are English language learners (ELLs), in the classroom. The article focuses on how the teacher develops and uses her emerging knowledge of Spanish to scaffold students' learning, specifically when…

The teaching and research communities in mathematics education agree that mathematical discussions pose challenges in elementary classrooms. These challenges continue to motivate research on mathematical discussions, with a focus on how students use talk in discussions. This study addresses the question, "What can teachers and researchers…

Bilingual preschoolers often perform better than monolingual children on false-belief understanding. It has been hypothesized that this is due to their enhanced executive function skills, although this relationship has rarely been tested or supported. The current longitudinal study tested whether metalinguistic awareness was responsible for this…
