本文探討以部落或社區為本－賽德克族太魯閣群語言之復振策略，屬於微觀層面的語言規劃之一。藉由提供青年參與以原住民文化及領域為導向之語言復振計畫經驗，進一步探討這種以部落或社區為本的復振策略，是否能在此關鍵時刻有效地減緩日益嚴重的瀕危語言轉移現象。本策略主要採用的執行方法包括：（i）社會戲劇和訪談法，（ii）以文化及領域為導向之語言課程規劃，（iii）師徒制語言教學，（iv）語言數位典藏，及（v）大學與部落夥伴關係。研究方法包括問卷調查，焦點小組訪談和觀察。研究結果顯示維持部落或社區年輕族人母語學習動機之重要性，並且發現強化全方位的身份意識、發展以文化及場域為導向之課程計畫、創造情感和關係本位的語言學習環境、及提供青年主導的機會，對瀕危語言學習及部落或社區為本的語言復振策略執行相當有助益。

This paper provides an understanding of young people's experiences of participating in a language revitalization project in an indigenous setting. Emerging from a community-based language revitalization initiative that is part of a micro-level language planning project in a Truku Seediq community, this study explores whether the community-based language revitalization initiative has contributed to the goal of stemming further indigenous language erosion at this critical point in the ongoing process of language shift. The project centers on five activities: (i) community theater and interviews, (ii) culture-based and domain-oriented weekly language classes, (iii) a master-apprentice program, (iv) language documentation and archiving, and (v) university-community partnerships. Methodologies include surveys, questionnaires, focus group interviews, and observations. The results of the study show the significance of motivation and suggest four main factors that can contribute to maintaining youth's motivation for learning an endangered language: a strong sense of holistic identity, a culturally-based and domain-oriented language curriculum, an affective and relational language learning environment, and the positioning of the youth as crucial agents of the community-based language revitalization initiative.
