本研究旨在探討臺灣雙語教育政策的影響之下，雙語實驗學校如何透過雙語教師專業發展社群以及雙語教師增能來發展並培育雙語教學團隊。本研究以質性個案研究作為研究架構，以深入了解個案學校具體如何推行雙語教育，並以「沃土」雙語模式為分析架構探討影響國中階段推行雙語教育的因素，以及雙語教師專業發展社群與雙語教師增能如何影響校內推動雙語教育。研究結果發現，雙語教師增能幫助教師提升自我效能感並精進教師的雙語教學技巧，而在內容與管道上必須多元化並賦予更多彈性空間。此外，雙語教師專業發展社群協助雙語教師精進雙語教學，其組成需為本國籍英語教師搭配學科教師。最後，透過個案學校的經驗提出對於臺灣國中階段實施雙語教育之省思與建議，並作為臺灣推動雙語教育時之參考。

The purpose of this study is to explore how a bilingual teaching team is formed and cultivated through a professional bilingual teacher learning community and teacher professional growth. This study chose qualitative case study as its research framework to deeply understand how to implement bilingual education in junior high schools. It selected a bilingual experimental curriculum school in Taipei and analyzed the background and development of its bilingual education. This study used the “fertile” bilingual model as the analysis framework to explore those factors that could affect the implementation of bilingual education in junior high schools. The findings are as follows. First, bilingual teachers could benefit from attending teacher training programs, workshops, and related activities in the aspect of their self-efficacy and to increase their teaching strategies. Second, the contexts and accesses of bilingual teacher training should be verified, diversified and given more flexibility. Third, a bilingual teacher professional community provides a platform for maintaining bilingual teachers’ instruction strategies and cooperation between administrators and teachers. Fourth, the composition of the community should be local English teacher and bilingual subject teachers. Lastly, this study put forward some reflections and suggestions on the implementation of bilingual education in junior high schools in Taiwan and serves as a reference for Taiwan to promote bilingual education nationwide.
