以改變理論探討新住民語文課程導入安置型評估之影響力研究

The Impact of Placement Assessment in New Immigrant Language Instruction: Insights from the Theory of Change

本研究以「改變理論（Theory of Change, TOC）」為核心架構，深入探討新住民語文課程導入安置型評估之實施機制與成效。研究目的在於探討安置型的級別評估在語文課程教學分流中的實質影響，並進一步透過社會投資報酬率（Social Return On Investment, SROI）分析法，評估該級別評估制度對學校與政策制定者等教育利益相關者所帶來的社會價值。研究設計涵蓋三大階段：第一階段透過深度訪談蒐集利害關係人對政策介入過程中的實際變化經驗；第二階段進行量化問卷調查，評估成果重要性、持續性與歸因程度；第三階段則進行成果驗證與貨幣化估算，建構完整的成果事件鏈（Outcome Chains）。本研究採立意抽樣，涵蓋全國五大分區（北一區、北二區、中區、南一區、南二區），以提升樣本的代表性與政策普遍適用性。透過實證資料分析，本研究發現導入安置型評估有助於提升教學資源配置效率與學習成效分流的精準性，進而促進新住民學生語文學習的公平與適性。以SROI分析結果顯示SROI為3.16，代表每投入1元可創造3.16元的社會效益，呈現高度的資源效益與教育制度擴散潛力。整體而言，本研究不僅驗證改變理論在教育介入評估中的應用價值，也為新住民語文政策優化提供實證依據與策略建議，具備高度政策參考價值與實務推廣潛力。

This study, grounded in the Theory of Change (TOC), explores the implementation and impact of placement assessments in new immigrant language programs. It aims to examine how level-based placement influences differentiated instruction and learning outcomes. Using the Social Return on Investment (SROI) approach, the study evaluates the societal value generated for key stakeholders, including schools and policymakers. Empirical analysis reveals that placement assessments enhance resource allocation efficiency and equitable learning opportunities. The research design comprises three main phases. In the first phase, in-depth interviews were conducted to gather stakeholders’ experiences of change resulting from policy implementation. The second phase involved a quantitative survey to assess the significance, duration, and attribution of outcomes. The third phase focused on outcome validation and monetization estimation, leading to the construction of comprehensive outcome chains. This study employed purposive sampling, covering five major administrative regions in Taiwan (Northern Region I, Northern Region II, Central Region, Southern Region I, and Southern Region II) to enhance the representativeness of the sample and ensure broad policy applicability. The SROI result of 3.16 indicates that every NT$1 invested yields NT$3.16 in social value, highlighting strong potential for policy impact and educational system optimization.
