本研究探討學前混齡融合班大肌肉活動介入，對特殊幼兒粗大動作之學習成效與教保服務人員之教學歷程。學習成效採單一受試研究法之A-B-C設計並採用PGMQS為評量工具，每週課程設計由研究者依據幼兒大肌肉活動當週表現設計下週活動教案，並請專家小組審核後執行。研究個案為三位不同障別特殊幼兒，在參與大肌肉活動10週後個案粗大動作品質之變化，利用視覺分析、效果值分析及GOOGLE表單進行資料處理做為學習成效之結果。而教保服務人員教學歷程採用行動研究法，在執行大肌肉活動過程中研究者進行每週教學省思與個案紀錄，透過不斷的發現問題-診斷問題-擬定教學計劃-選擇方法與分析資料-省思與結論之循環，介入10週結束後將蒐集到的資料教學省思、個案觀察紀錄為教學歷程之結果。結果一、本研究個案在大肌肉活動介入10週後，從效果值分析顯示具有效果並從三角驗證結果顯示對於個案身體動作表現有助益。二、透過研究者的教學省思內容，建議教保人員在設計教案時依據幼兒表現及興趣隨時調整教學策略，並以遊戲方式進行為佳。建議未來研究可擴大研究對象人數、障礙類別。 This study aims to discuss the effectiveness of exceptional children's gross motor skill learning and preschool educators' teaching through the intervention of big muscle activities in mixed-age inclusion classes.This study employed an A-B-C single-subject research design to study the learning effectiveness and the Preschooler Gross Motor Quality Scale （PGMQS） as the main assessment tool.The researcher designed a lesson plan of big muscle activities for the following week based on children's weekly performances of big muscle activities.The lesson plan then was implemented after being reviewed by an expert group.The research subjects consisted of three students with different classifications of disabilities.The visual, C-statistics, effect-size analyses, and Google forms had been conducted to process and analyze the collected data in order to have comprehensible results of their learning effectiveness.The action research was adopted in this study to assess preschool educators' teaching effectiveness. Throughout the implementation of big muscle activities, the researcher had collected all weekly teaching reflections and case records from the repeated cycle of problem discovery, problem diagnosis, lesson-plan design, method adoption and data analysis, and reflection and inference.To obtain the study results on teaching effectiveness, we conducted a coding analysis on all the collected data, including the teaching reflections and case observation records, at the end of the 10-week big muscle activity intervention. The results of this study are shown as follows： 1.After the subjects finished their 10 weeks of big muscle activity intervention, it is obvious that the consecutive values on the run chart present an upward trend.The effect size analysis also shows medium-high or high effectiveness.It indicates a positive effect of early intervention on subjects' body movement performances.We also used triangulation in this study, and the results also indicate that there had been a significant improvement in the subjects' body movement performances. 2. Based on the researcher's teaching reflections, preschool educators are suggested to make necessary adjustments to their teaching strategies and include more classroom games into their teaching.It is also suggested that future research should expand the sample size, include more classifications of disabilities.
