Information about children's cultural and linguistic diversity and language acquisition patterns is important for the development of sustainable educational practices. While there is some knowledge about language maintenance and loss in adults and older children, there is limited information about young children. The first three waves of data from the Longitudinal Study of Australian Children (LSAC), involving 4252 young children, were considered longitudinally over the first five years of life to identify patterns of language maintenance and loss among those who speak languages other than English. The most common languages other than English spoken by the children were Arabic, Vietnamese, Italian, Spanish, and Greek and 9.1% of all children were reported to use a language other than English at wave 1, 15.7% at wave 2, and 15.2% at wave 3. Overall, 91.5% of children maintained speaking a language other than English between wave 1 and wave 2, and 86.6% did so between wave 1 and wave 3. Children's patterns of language acquisition and loss over the first five years of life varied within and between language groups. For example, Arabic-speaking children tended to maintain Arabic throughout early childhood, whereas Italian-speaking children's use of Italian decreased over the first five years of life while use of English steadily increased. Environmental and personal factors such as parental language use, presence of a grandparent in the home, type of early childhood care, first- and second-generation immigrant status, and parental perception of support from the educational environment were related to language maintenance among non-English speaking children. 相似文献

Recent science-education reforms have targeted students’ ability to ‘talk science’, especially in science classrooms. Prior research has shown that participation in scientific discourse in class is one of the most challenging scientific-literacy tasks, and particularly complex for English language learners (ELLs) at the upper elementary level. The present study explores this issue in a fourth-grade science classroom in the United States in which students from various linguistic and cultural backgrounds were studying together. Specifically, it analyzes the case of a focal Asian-background ELL who encountered challenges in her attempts to respond to the teacher’s questions and participate in the classroom academic discourse on earth science. Our analysis indicated that this ELL was unaware of the teacher’s expectations regarding the intertextual connections and academic language required to successfully accomplish science tasks. The ELL’s unexpected responses exposed a complex set of academic and social issues – notably, gaps between the teacher’s, students’, and ELL’s own expectations about language participation – that could have contributed to her supposed behavioural problems. 相似文献

The literature of gerontology may be found in the journals of many disciplines and in the popular press. Only journals published in the U.S. and devoted exclusively or in large part to the literature of social gerontology are described here. Journals intended primarily for the layman rather than for the professional worker are not included, even though they may contain some material of interest to the professional. All available bibliographic information is given, and special features of each journal are described. Newsletters of more than local significance are listed but not individually described. 相似文献

从知识组织的角度介绍概念映射的重要性,分析概念映射方法的深度及研究情况。面向等同、等级和相关映射的类型特征,提出基于精确匹配可以继承的概念映射关系,并分析由于中英文词表异质异构而引起的映射关系矛盾情况,如由于代项或参项而引起的一个概念精确匹配到多个概念的问题、等级映射的深度及相关映射的选择等,并基于汉语用户的需要及编制规则提出相应的处理规则。 相似文献
