국문 초록

본 연구에서는 음성합성기술이 포함된 프로그램을 태블릿 PC에 설치하여 보완대체의사소통 중재를 실시하고 그러한 중재가 발달장애아동의 의사소통능력 증진에 어떠한 효과가 있는지를 알아보고자하였다. 연구 참여자는 발달장애 아동 3명이었으며 이들을 위한 중재는 중다 간헐 기초선 설계에 따라 예비단계, 기초선, 중재, 일반화, 유지의 순서로 진행되었다. 연구 결과에 의하면, 중재 이후 아동들의 어휘(NDW)와 구문길이(MLU-w)가 증가하여 언어적 능력 증진에 효과가 있는 것으로 나타났다. 또한 의사소통 기능과 방식이 다양하게 증가하여 화용적 능력 증진에도 효과가 있는 것으로 나타났다. 본 연구는 제한적이기는 하지만 한 낱말 표현이 가능한 발달장애아동을 대상으로 하이테크놀로지를 이용한 보완대체의사소통 중재를 실시하고, 그러한 중재가 화용적 능력뿐 아니라 언어적 능력 모두를 포함한 의사소통능력 촉진에 효과가 있음을 입증하였다는 데 그 의의가 있다.

영문 초록

The purpose of this research is to investigate the effects of AAC intervention using tablet computer adopting text to speech(TTS) program on children who are able to speak in limitedly expressed words. The effect was considered in both aspects of communicative competence, linguistic and pragmatic competence. Three children with developmental disabilities were participated in subjects for AAC intervention which was with performed multiple probe design. This research measured number of different words(NDW) and mean length of utterance(MLU-w) to examine linguistic communicative competence, and observed the change of communicative functions and communication modes to analyze pragmatic communicative competence. NDW and MLU-w was measured by speech and AAC device. Communicative functions were analyzed by speech, AAC device, and gestures. Communicative methods were separately analyzed by speech, vocalization, gestures, and AAC device. The results of this research are as follows. Firstly, NDW of children with developmental disabilities were increased dramatically after AAC intervention with high technology, and the improvement was persisted in maintenance stage. Secondly, MLU-w of the children were increased after AAC intervention with high technology and maintained thereafter. Usage of AAC mainly contributed to the improvement. Thirdly, communicative functions of the children either became diverse or increased in frequency. Lastly, AAC intervention with high technology was effective in diversifying communication modes. Especially this research verified intensification in forms of expression as a result of increased interaction by utilizing AAC. In summary, AAC intervention with high technology increased NDW and MLU-w as well as improved communicative functions, and diversified modes of communication in children with developmental disabilities. This research is clearly meaningful in suggesting the effectiveness of AAC intervention which improves linguistic and pragmatic communicative competence to children with disabilities who are able to speak in limitedly expressed words.
