1“梦想”普通话标准化评估在听障儿童语言测试中的应用显示文摘目的本文讨论了用口语交流的听障儿童语言发展效果评估的最新实证。方法研究强调,语言评估须足够具体,才能捕捉到细微的词汇及语法缺陷。'普通话听力理解和表达能力标准化评估'(Diagnostic Receptive and Expressive Assessment of Mandarin,DREAM,译为'梦想')抓住儿童普通话习得的核心特征,是基于中国大陆地区的普通话儿童来建立常模的综合性的语言测试,可以测量中国大陆儿童在各个年龄阶段的语言技能。声音和图片通过平板电脑呈现,答案以触屏的方式进行记录,减少了人为差异,使操作更加标准化。结果本文报告了DREAM的题目设计、信度和效度研究等内容。试验研究显示,该测试可提供听障儿童语言发展的详细信息。测试可提供诊断儿童具体语言发育缺陷的报告,用来指导康复计划的制定,使更加个性化的康复干预成为可能。结论 DREAM是转化科学的成功范例——把科研结果从语言习得的循证研究转移到临床评估和干预康复的应用领域。以循证医学为基础的综合性普通话语言测试将推动中国听障儿童干预和康复的效果评估研究。刘雪曼 de Villiers,Jill 宁春岩 Rolfhus,Eric Hutchings,Teresa Lee,Wendy 江帆 章依文 2015中华耳科学杂志2015,13,4:7
2New language outcome measures for Mandarin speaking children with hearing loss显示文摘Objective:The paper discusses recent evidence on the assessment of language outcomes in children with hearing loss acquiring oral language.Methods:Research emphasizes that language tests must be specific enough to capture subtle deficits in vocabulary and grammar learning at different developmental ages.The Diagnostic Receptive and Expressive Assessment of Mandarin(DREAM) was carefully designed to be a comprehensive standardized Mandarin assessment normed in China's Mainland.Objective:The paper discusses recent evidence on the assessment of language outcomes in children with hearing loss acquiring oral language.Methods:Research emphasizes that language tests must be specific enough to capture subtle deficits in vocabulary and grammar learning at different developmental ages.The Diagnostic Receptive and Expressive Assessment of Mandarin(DREAM)was carefully designed to be a comprehensive standardized Mandarin assessment normed in China's Mainland.Results:This paper summarizes the evidence-based item design process and validity and reliability results of DREAM.A pilot study reported here shows that DREAM provided detailed information about hearing impaired children's language abilities and can be used to aid intervention planning to maximize progress.Conclusion:DREAM represents an example of translational science,transferring methods from empirical studies of language acquisition in research environments into applied domains such as assessment and intervention.Research on outcomes in China will advance significantly with the availability of evidence-based comprehensive language tests that measure a sufficient age range of skills,are normed on Mandarin speaking children in China's Mainland,and are designed to capture features central to Mandarin language acquisition.Xueman Liu Jill de Villiers Wendy Lee Chunyan Ning Eric Rolfhus Teresa Hutchings Fan Jiang Yiwen Zhang 2016Journal of Otology2016,11,1:4
