本研究目的為探討應用手勢溝通教學提升發展遲緩幼兒溝通能力成效。研究對象為三名22-31個月發展遲緩幼兒。研究方法採用單一受試之A-B-A`倒返實驗設計,共分為基線期、介入期與維持期三階段。自變項為手勢溝通教學方案,依變項為受試者之溝通行為。研究者收集資料結果繪製成曲線圖,並進行視覺分析,用以解釋發展遲緩幼兒接受手勢溝通教學後,其溝通行為的改變。本研究的主要發現如下: 一、手勢溝通教學有助於改善三位發展遲緩幼兒溝通能力。 二、手勢溝通教學對三位發展遲緩幼兒在維持期溝通能力也有成效,尤其是在主動口語表達部份成效最佳。 三、家長與老師均支持手勢溝通教學對三位發展遲緩幼兒在溝通能力的改善。 研究者根據上述結果,分別針對手勢溝通教學及未來相關研究提出具體之建議,提供其他研究者作為參考,並作為發展遲緩幼兒早期療育教學介入的方案之一。
The purpose of this study was to evaluate the effect of gesture communication teaching to children with developmentally delayed in their communication ability. Samples were three developmentally delayed children within 22-31 months old. The study used the single-subject experimental A-B-A` design, including 3 steps: The first step was to record children’s baseline communication ability data, the second step was to implement experimental intervention, which was gesture communication teaching, and the third step was to evaluate the improvement and maintaining effect of children’s communication ability. Charts and visual illustrations were utilized to explain the outcome effect. The major findings were summarized as follow: 1. Gesture communication teaching can improve communication ability for children with developmentally delayed. 2. Gesture communication teaching has maintaining effect for children with developmentally delayed, especially in their oral verbal expression. 3. Parents and teachers all agree that gesture communication teaching improves communication ability for children with developmentally delayed. According to the findings of this study, suggestions and recommendations are proposed when applying gesture communication teaching as an intervention for children with developmentally delayed.
