Research has identified English oral language proficiency as being critical for bilingual students' literacy development. This study examines developmental patterns and associations among oral vocabulary and narrative skills in a longitudinal sample of 24 Spanish/English bilingual children from low socioeconomic backgrounds so as to further our understanding of the development of oral proficiency.
English and Spanish data were gathered using standardized vocabulary tests and narrative elicitation tasks provided to kindergartners and first graders. Narratives were coded for length using two measures of productivity and for quality at two levels: story score and language score. Descriptive, correlation, multivariate, and regression analyses were conducted.
Significant gains from kindergarten to first grade were found for all English oral language measures. Despite showing improvements in English vocabulary, the majority of children continued to score below the monolingual mean in first grade. For English narrative productivity, total number of different words (TDW) proved to be a sensitive developmental measure in contrast to total number of words (TNW). In Spanish, significant gains were noted only for narrative story score. Kindergarten Spanish story scores predicted first-grade English narrative quality even when controlling for the effects of English vocabulary and English narrative productivity. First-grade Spanish narrative quality was best predicted by Spanish vocabulary.
The need for early assessment and monitoring of expressive vocabulary and oral narrative skills, and the potential contributions of Spanish story organization skills to English narrative performance in bilingual children from low socioeconomic families, are highlighted.
研究表明,英语口语能力对双语学生的读写能力发展至关重要。本研究调查了24名来自社会经济背景较低的西班牙裔/英语双语儿童纵向样本中的口语词汇和叙事技巧的发展模式及关联,以增进我们对口语能力发展的理解。
通过向幼儿园儿童和一年级学生提供标准化词汇测试和叙事引出任务来收集英语和西班牙语数据。叙事根据两种产出量度进行长度编码,并在两个层面进行质量编码:故事分数和语言分数。进行了描述性、相关性、多变量和回归分析。
所有英语口语指标从幼儿园到一年级都有显著提高。尽管英语词汇有所进步,但大多数儿童在一年级时的得分仍低于单语儿童的平均水平。对于英语叙事产出,与单词总数(TNW)相比,不同单词总数(TDW)被证明是一个敏感的发展指标。在西班牙语方面,仅叙事故事分数有显著提高。即使控制了英语词汇和英语叙事产出的影响,幼儿园西班牙语故事分数仍能预测一年级英语叙事质量。一年级西班牙语叙事质量的最佳预测指标是西班牙语词汇。
强调了对表达性词汇和口语叙事技巧进行早期评估和监测的必要性,以及西班牙故事组织技巧对社会经济背景较低的双语儿童英语叙事表现的潜在贡献。
