Beginning to Read in Vietnamese: Kindergarten Precursors to First Grade Fluency and Reading Comprehension

A Narrative Approach to Synthesizing Research on Vietnamese Bilingual and Monolingual Children

PURPOSE

This review article offers a narrativized synthesis of my research over the past 15+ years with Vietnamese-speaking children based on data collected from individual bilingual and monolingual children in preschool and elementary schools.

METHOD

I begin with a positionality narrative to describe who I am in relation to the research conducted. I provide an overview of the research program including tool building and how my research with bilinguals in the United States led me to international collaborations in Vietnam.

RESULTS

I present main findings from this body of work in three areas: typical bilingual development, reading performance in Vietnam, and characteristics of developmental language disorder in the Vietnamese language. Implications within each area are discussed in terms of clinical application and future research directions. Practitioners and researchers alike can freely access the Vietnamese assessment tools created and validated to date from our website, https://vietslp.sdsu.edu/.

CONCLUSIONS

This research overview aims to offer clinicians and researchers the sociocultural context for understanding the relevance of this body of research. It also serves as an invitation for new generations of scholars, particularly scholars of color, to see their own unique positionings and perspectives as valuable and necessary for scientific innovation and progress.

Vietnamese children with and without DLD: Classifier use and grammaticality over time

INTRODUCTION

One way to identify Developmental Language Disorder (DLD) is to establish clinical markers in a language to serve as reliable indicators of the disorder. This study embarks on the search for clinical markers for Vietnamese using longitudinal data from children with and without DLD.

METHODS

We matched ten children previously classified with DLD to ten with typical development (TD) by age and gender. Participants completed a story generation task at three time points: kindergarten, first, and second grade. Overall grammatical development was measured using mean length of utterance, MLU, and proportion of grammatical utterances, PGU. We examined a language-specific feature, classifiers, in terms of accuracy (omission errors), diversity (number of different classifiers), and productivity, or the use of classifiers in constructions of two-to-three elements (classifier+noun, numeral+classifier+noun). Longitudinal change and group differences were examined using linear mixed modeling, supplemented by linguistic analysis.

RESULTS

Both groups increased in MLU and PGU over time. The DLD group performed lower in kindergarten and continued to show lower performance over time on these measures. Classifier omission errors decreased over time with no group differences. Classifier diversity increased across groups, with lower performance by the DLD group in kindergarten and over time. For classifier productivity, TD children used classifiers in multiple constructions in kindergarten and maintained the same level over time. In contrast, children with DLD had minimal use of three-element constructions in kindergarten but increased in productivity over time.

CONCLUSIONS

Children with DLD produce shorter utterances with relatively more grammatical errors compared to their TD peers in the early school years. Though no longer committing classifier omission errors, children with DLD showed more restricted use of classifiers in terms of the number of different classifiers and constructions produced. Findings inform the search for Vietnamese clinical markers of DLD.

Reading Attitudes in Vietnam: Initial Study of the Early School Years

Whereas cognitive and linguistic factors for learning to read have been extensively studied, less is known about affective factors including children's attitudes toward reading. Studies primarily from English-speaking and Western countries show gradual declines in reading attitudes in elementary school (McKenna et al., 1995) and a positive association between reading attitudes and achievement (Petscher, 2010). Children from Asian and African countries are underrepresented in this literature; whether these patterns can be generalized across cultures needs further investigation. This longitudinal study examined the reading attitudes of 84 children in Vietnam from grades 1 to 2 and their relations to reading performance, as measured by translated and adapted versions of the Elementary Reading Attitude Survey and Early Grade Reading Assessment, respectively. This sample from Vietnam showed a small decline in reading attitudes over time, particularly in attitudes toward academic reading. However, children on average reported feeling happy about reading in both grades. Correlations revealed different patterns of association between reading attitudes and performance based on the reading measure employed, grade level, and type of reading in question (academic versus recreational). In grade 2, reading attitudes explained unique variance in reading comprehension even after text fluency and mother's education were considered. We present a margins plot to visualize the role of reading attitudes on reading comprehension. We discuss educational implications and future directions.
