Relationships between reading,phonological skills and language development in individuals with Down syndrome: A five year follow-up study

This article is based on language, memory andreading information gathered for a five yearfollow-up study of 30 children and adolescentswith Down syndrome, aged from 10 to 24 years atthe end of the study. At Time 1, 10individuals were classified as readers but byTime 2 this number had risen to 16. Readers significantly outperformed non-readerson tests of nonverbal ability, languagecomprehension and production, phonologicalmemory and phonological awarenesss. However,some of these differences could be accountedfor by readers' significantly lower hearingthresholds. Phonological memory and earlyletter knowledge at Time 1 were significantpredictors of reading scores for Time 2readers, after controlling for age, nonverbalability and corresponding Time 1 readingscores. There was no evidence that learning toread had a significant impact on later languagecomprehension, but early reading skills may besignificant predictors of MLU five years later,after controlling for age, nonverbal abilityand hearing.     

数学新境——MathDL数学数字图书馆

作为国家科学教育数字图书馆（NSDL）通道项目之一,数学数字图书馆（MathDL）是由美国国家科学基金会（NSF）资助、美国数学协会（MAA）主办的,致力于提升大学数学教育水平的数字图书馆项目。MathDL集合了多种类型数学资源,通过建立集中平台为用户提供专业信息服务。文章针对该数字图书馆的背景、建设、现状及发展进行了综合评述,包括数字资源及组织、服务特点、技术特征及作者的评价与建议。     

教育学的门户网站——起跑点与教育进行时数字图书馆

起跑点（Starting Point： Teaching Entry Level Geoscience）和教育进行时（Pedagogy in Action）这两个数字图书馆都是由卡尔顿大学（Carleton College）的科学教育中心（SERC）开发的项目。它们作为SERC教育学图书馆的门户,旨在为地球科学教育工作者提供高质量的教学方法和相关的教学经验,同时通过鼓励教学者上传相关的教学案例,反映自己的教学方法和教学活动,并探索新的教学方法,为教育工作者提供教学方面的资源。这两个数字图书馆存在着紧密的联系。文章从该馆建设、馆藏组织、技术特征、界面设计、服务特点等方面分别对这两个数字图书馆进行了评述,并给出了作者的评价与建议。     

科技赋能助推精准脱贫

党的十八大以来,以习近平同志为核心的党中央将扶贫开发提高到治国理政的重要位置。科技扶贫作为贯彻精准扶贫、精准脱贫方略的重要内容,是发挥科技、人才支撑作用的有效途径,是打赢脱贫攻坚战的关键性举措。脱贫攻坚战打响以来,科技扶贫工作取得重要进展,文章提出进一步促进科技扶贫工作的5点思考:科技赋能助力培育扶贫产业;大力培育贫困村创业致富带头人;统筹整合各类帮扶资源;做好科技扶贫案例的示范推广;实现信息共通共享。
