The paper discusses recent evidence on the assessment of language outcomes in children with hearing loss acquiring oral language.
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 Mainland China.
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.
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 mainland China, and are designed to capture features central to Mandarin language acquisition.
本文探讨了近期有关听力损失儿童习得口语的语言结果评估的证据。
研究强调语言测试必须足够具体，以捕捉不同发育阶段在词汇和语法学习方面的细微缺陷。普通话诊断性接受与表达评估（DREAM）经过精心设计，是一项在中国大陆进行标准化的全面普通话评估。
本文总结了DREAM基于证据的项目设计过程以及效度和信度结果。此处报告的一项初步研究表明，DREAM提供了有关听力受损儿童语言能力的详细信息，可用于辅助干预计划以实现最大程度的进步。
DREAM代表了转化科学的一个范例，即将研究环境中语言习得实证研究的方法应用于评估和干预等应用领域。随着基于证据的综合语言测试的出现，中国的相关研究将取得显著进展，这些测试能够测量足够广泛的技能年龄范围，以说普通话的中国大陆儿童为常模，并旨在捕捉普通话语言习得的核心特征。
