Literacy skills are essential for full inclusion in society, particularly for individuals with Down syndrome who have limited intelligible speech, as literacy provides an additional modality for accessing receptive and expressive language. Telepractice provides convenient access to services in the natural context that might otherwise be inaccessible for many individuals. The current case study explored the effect of a telepractice intervention with home practice that consisted of an AAC Transition to Literacy (T2L) decoding feature, designed to support single word reading.
This paper presents a case study of a young boy, Henry (pseudonym), with a diagnosis of Down syndrome, limited functional speech, and limited literacy skills. Henry was provided with a 12-week intervention that consisted of the introduction of an AAC technology decoding feature that modeled single word decoding. He participated remotely at home, with support from his mother. Data was collected on Henry's accuracy of (a) single word reading and (b) generalization to single word spelling.
Henry demonstrated increased single word reading skills, particularly for words presented with the T2L decoding feature, but minimal generalization to spelling was observed.
The findings indicated that an AAC technology T2L decoding feature that offered models of single-word decoding may be beneficial for supporting early literacy skills in young children with Down syndrome. Furthermore, telepractice with additional home engagement with the intervention appears to be a viable option for the delivery of literacy intervention. Implications for clinical practice and directions for future research are discussed.
读写能力对于充分融入社会至关重要,特别是对于那些语言表达有限的唐氏综合征患者而言,因为读写能力提供了一种额外的方式来获取接受性和表达性语言。远程医疗实践提供了在自然环境中便捷获取服务的途径,否则许多人可能无法获得这些服务。本案例研究探讨了一种包含家庭练习的远程医疗实践干预的效果,该干预采用了辅助沟通(AAC)向读写能力过渡(T2L)的解码功能,旨在支持单字阅读。
本文介绍了一个小男孩亨利(化名)的案例研究,他被诊断患有唐氏综合征,功能性言语有限,读写能力也有限。亨利接受了为期12周的干预,包括引入一种AAC技术解码功能,该功能模拟单字解码。他在母亲的支持下在家中远程参与。收集了关于亨利(a)单字阅读准确性和(b)单字拼写泛化的数据。
亨利的单字阅读技能有所提高,特别是对于呈现T2L解码功能的单词,但观察到拼写泛化极少。
研究结果表明,提供单字解码模型的AAC技术T2L解码功能可能有助于支持唐氏综合征幼儿的早期读写能力。此外,远程医疗实践以及增加家庭对干预的参与似乎是提供读写能力干预的可行选择。文中讨论了对临床实践的启示以及未来研究的方向。
