Bitsboard應用程式介入方案對提升發展遲緩幼兒語言表達能力之成效

The Effectiveness of Bitsboard App in Improving Language Expression for a Child with Developmental Delay

本研究目的在探討應用程式（Bitsboard）介入方案對發展遲緩幼兒語言表達能力訓練之成效，研究採單一個案研究法之跨行為多探測設計，自變項為應用程式，依變項為詞彙命名、需求表達兩種語言表達能力之表現。研究對象為3歲10個月發展遲緩幼兒1名，本研究進行7週介入，以語言表達評量表來蒐集學生語言表達能力，研究資料以目視分析、C統計及效果量來分析語言表達能力學習成效資料，並以問卷及訪談內容分析本研究的社會效度。本研究結果如下：一、應用程式對發展遲緩幼兒語言表達能力具有立即成效。二、應用程式對發展遲緩幼兒語言表達能力具有維持成效。三、家長和教師對應用程式介入方案的內容，皆感到滿意。四、家長和教師對應用程式介入方案增進研究對象語言表達能力，皆持正向肯定的態度。最後，依據研究結果，提出未來教學與研究的相關建議。

The purpose of this study is to investigate the effectiveness of increasing the language expression through Bitsboard intervention program for a child with developmental delay. The participant of this study was a 3 years and 10 months child with developmental delay. The study used multiple probe design across behaviors of single-subject experimental design. The intervention program was seven weeks. The research used language expression scale as posttest. Visual analysis, C statistics, and effect size were used to analyze the data of language expression. The questionnaires and interviews were used to analyze the social validity. The results of this study are as follows: 1. The intervention of Bitsboard had the immediate effects on the language expression. 2. The intervention of Bitsboard had the maintenance effects on the language expression. 3. Parents and teachers agreed that Bitsboard intervention had positive effects for the participant's language expression. Finally, according to the results of the study, suggestion for teaching and future research were discussed.
