Predictors of English reading comprehension: Cantonese-speaking English language learners in the U.S
2013
In this paper, first language (L1) and second language (L2) oral language and word reading skills were used as predictors to devise a model of reading comprehension in young Cantonese-speaking English language learners (ELLs) in the United States. L1 and L2 language and literacy measures were collected from a total of 101 Cantonese-speaking ELLs during the early spring of second grade. Results show that English vocabulary and English word decoding, as measured with real and nonsense words, played significant roles in English reading comprehension. In particular, results highlight the crucial role of English vocabulary in the development of L2 English literacy skills. English listening comprehension did not predict English reading comprehension. Theoretical and practical implications are discussed.

Consequences of multilingualism vary from offering cognitive benefits to poor educational and cognitive outcomes. One aspect of multilingualism that has not been systematically examined is the typology of multilinguals' languages: Do differences and similarities between languages multilinguals are exposed to contribute to the development of their cognition and brain? We investigated
n
= 162 5–6-year-olds with various language backgrounds on a monolingual-to-quintilingual continuum. Our results show that typological linguistic diversity can be related to expressive vocabulary knowledge in the dominant language. On neural level, it relates to brain activation patterns in (among others) the PGa area in the bilateral IPL, a brain region previously associated with multilingual experience, but never with language typology. We propose an ecologically valid way of describing the continuum of multilingual language experience and provide evidence for both the cognition and the brain of multilingual kindergartners to be related to the typological linguistic diversity of their environment.

Dual language learners (DLLs) are sensitive to teachers’ language influence in early childhood classrooms. In this mixed methods study incorporating 53 teachers from 28 preschools in Northern California, we investigated the characteristics of teachers’ language use in preschools teaching Chinese–English and Spanish–English DLLs. We further examined the links of teachers’ language use to the DLLs’ expressive vocabulary in English and their heritage language (HL), controlling for home language exposure and other confounding variables. Finally, we conducted interviews with teachers to understand how they make meaning of their daily language practices. The sample of children consisted of 190 Chinese–English (N = 125) and Spanish–English (N = 65) DLLs (mean age = 48.3 months; 48% females). The teacher survey showed that most teachers spoke two or more languages and used a mix of English and their HL during their interactions with DLLs. The results of random-intercept models showed that teachers’ language use did not uniquely predict children’s vocabulary, controlling for family-level factors. However, the teachers with more years of teaching DLLs oversaw children with a higher HL vocabulary. The interview data revealed that teachers employ several strategies to communicate with DLLs and support HL maintenance. Our study reveals the multilingual backgrounds of preschool teachers and the rich language strategies they implement in multilingual classrooms. Future directions concerning the quality and development of teachers’ language use are discussed.

Child second language development of English tense and aspect: The role of narrative organization
2022
Much research has documented that second language (L2) development of tense and aspect markers is influenced by a range of factors that include cross-linguistic influences, phonological nature of forms, inherent semantics of predicates, and discourse structure. Nonetheless, relatively little research has examined the role of discourse organization in the development of tense and aspect marking. To expand our understanding of L2 tense and aspect, this study examined child L2 development of English tense and aspect in oral narratives in relation to the foregrounding and backgrounding of narrative discourse. Thirty-eight learners’ oral narratives were elicited, using Frog, Where Are You? (Mayer, 1969) three points in time: kindergarten, Grade 1, and Grade 2. The foreground in oral narratives was associated with more frequent use of the simple past than the background across the grade levels. While the occurrence of the simple past did not necessarily mark the foreground, the simple past emerged as the dominant form in the foreground in Grade 1. In the background, on the other hand, it took longer for the past forms to catch up with the non-past forms. The simple past became dominant in the background in Grade 2.

Development of vocabulary in Spanish-speaking and Cantonese-speaking English language learners
2014
This study examines vocabulary growth rates in first and second languages for Spanish-speaking and Cantonese-speaking English language learners from kindergarten through second grade. Growth-modeling results show a within-language effect of concepts about print on vocabulary. Language exposure also had an effect on English vocabulary: earlier English exposure led to larger English vocabulary in kindergarten. There was no interference of early English exposure on native-language vocabulary. Moreover, Cantonese-speaking children had higher English expressive vocabulary scores than Spanish-speaking children and this difference remained for the 3 years. In contrast, although there were no significant differences in first language vocabulary at the start of kindergarten, Spanish-speaking children had steeper growth rates in first-language vocabulary than Cantonese-speaking children, after controlling for language of instruction and first-language concepts about print.

English vocabulary development in bilingual kindergarteners: What are the best predictors?
2006
This study examines growth rates in vocabulary over an academic year for 150 Latino English language learners. In October, February, and June of kindergarten, participants completed standardized measures of receptive and expressive vocabulary. Before the second and third assessments, a third of the children watched Arthur three times a week during school hours, while another third viewed Between the Lions. The last third did not view either show during school hours. Data on children's preschool experiences and home literacy activities were collected. Growth modeling analyses show while there were no effects of classroom viewing, children who viewed Arthur and Between the Lions at home had steeper growth trajectories than those who had not. Additional effects of native language home use and preschool attendance were seen. Boys displayed better English vocabulary skills than girls. These findings suggest the importance of English exposure and native language maintenance for English L2 vocabulary development.

Parental level of education, instruction time, and amount of language practice that children receive have enhanced our understanding of how bilingual and multilingual children learn to comprehend text. Guided by the simple view of reading and the interdependence hypothesis, this longitudinal study conducted in Canadian French immersion programs examined the (a) within- and cross-language association between oral language skills and reading comprehension of bilingual English–French and multilingual children and (b) patterns of growth, while controlling for possible influences of parental level of education and methods of instruction on reading achievement. The sample included 150 children tested once at the beginning of Grade 4 (T1) and again at the end of Grade 4 (T2) and in Grade 6 (T3). Individual growth modeling revealed that bilingual and multilingual children showed similar development in oral language and reading skills across the timeframe. Moreover, growth in English and French reading comprehension was associated with within-language variables. English reading comprehension in Grade 4 was also associated with cross-language variables, including French listening comprehension and vocabulary knowledge. Reading development in the second and third language is enhanced in contexts where classroom instruction, as well as social, economic, and educational opportunities to learn, is equivalent for all students.

Auditory plasticity

Learning to read transforms the brain, building on children’s existing capacities for language and visuospatial processing. In particular, the development of print-speech convergence, or the spatial overlap of neural regions necessary for both auditory and visual language processing, is critical for literacy acquisition. Print-speech convergence is a universal signature of proficient reading, yet the antecedents of this convergence remain unknown. Here we examine the relationship between spoken language proficiency and the emergence of the print-speech network in beginning readers (ages 5–6). Results demonstrate that children’s language proficiency, but not their early literacy skill, explains variance in their print-speech neural convergence in kindergarten. Furthermore, print-speech convergence in kindergarten predicts reading abilities one year later. These findings suggest that children’s language ability is a core mechanism guiding the neural plasticity for learning to read, and extend theoretical perspectives on language and literacy acquisition across the lifespan.
•We studied spoken and written word processing in 5–6 year olds using fMRI.•Similarity between print and speech processing is related to successful reading in adults.•In beginning readers, language proficiency shapes the emerging print-speech network.•Print-speech neural convergence in kindergarten predicts reading one year later.

Objective:This longitudinal study investigates whether reading strategies are influenced by the orthographic depth of languages, specifically Spanish or Cantonese, acquired through enrollment in bilingual immersion programs. Spanish shares an alphabet with English and is considered a phonologically transparent language (Sun et al., 2022). Research has shown that second language learners of Cantonese, an opaque language, performed better on orthographic awareness tasks that involve whole-word visual information processing (Wang and Geva, 2003). We hypothesize that students enrolled in a bilingual immersion program will outperform peers in general education (GENED) on selected reading tasks. More specifically, those in Spanish-immersion programs will perform better on English tasks involving phonological processing; whereas those in Cantonese-immersion programs will perform better on single-word/character processing tasks.Participants and Methods:Participants (n=102) were native English speakers recruited from the San Francisco Unified School District. Our sample included 42 females and 60 males. Thirty-nine identified as White, 33 Mixed Race, 25 Asian, 4 Latinx, and 1 Black. Thirty-nine children were in GENED, 33 in Spanish immersion programs (Sp), and 30 in Cantonese immersion programs (Cn). Each child was assessed on a core language/behavioral battery at Kindergarten (T1) and 2nd-3rd grade (T2). Time 2 participants were between 7 and 9 years old.Those that scored at least one standard deviation below the mean (SS=85) on a nonverbal intelligence screener (KBIT-2 Matrices) were excluded to mitigate confounds of intellectual disabilities. Groups' performance in English was compared on English tasks involving phonological processing (CTOPP-2 Blending Words and Elision) and single-word/character information processing tasks (WJ-IV Letter Word Identification and KABC-II Rebus).Results:Simple main effects analysis showed that time did have a statistically significant effect on test performance (p <0.001). At T2, analysis revealed a significant impact of school enrollment on Blending Words [F (2, 51.0) = 4.19, p = 0.018]. As predicted, post-hoc analysis revealed the students enrolled in the Spanish-immersion program significantly outperformed those in general education on this task. Across the other three tasks, those enrolled in Spanish and Cantonese immersion programs performed as strong as or better than those in GENED, but the variability was not statistically significant.Conclusions:This study uniquely isolated the effects of bilingual education without confounding factors of access to resources of a more heterogeneous socioeconomic sample. Mixed results partially supported our hypotheses: Spanish-immersion participants performed significantly better than those in GENED on one English phonological processing task (Blending Words). Although Cantonese immersion students had a higher mean performance than those in GENED on single-word/-character processing tasks, the variance was not statistically significant. This implies that bilingual education may offer advantages in either reading strategy. According to the literature, characteristics of a language may influence literacy acquisition; thus, subsequent research may continue to examine the effect of learning multiple languages with varying levels of orthographic depth on the development of English reading strategies.
