Second Life為新興的網路虛擬實境軟體。近年來，已有很多運用於教育領域的實例，其仿真情境及營造使用者自由交流的特質，讓外語教學者也躍躍欲試。台灣因華語教學市場的限制及線上教學市場的潛力，給予Second Life與華語教學結合的契機，本研究目的是運用Second Life於培訓華語師資於一對一線上教學，以協助實習教師對線上教學的認知，進而探討實習教師在面對虛擬教學環境時所面臨到的困難、教學成長及其他具體相關注意事項，以提供給後繼有意從事培訓遠距師資的專家學者參考。

Second Life, a virtual reality space, has gained great attention among foreign language teachers and has been viewed as a potential education tool. Due to the limited teaching opportunities for pre-service teachers in Taiwan and the potential power of Internet, this study adopted Second Life as an authentic Mandarin pre-service teacher teaching environment and offered a systematic training model to educate those pre-service teachers. The purposes were to create an online teaching environment to allow pre-service teachers gain practical knowledge in one to one teaching and further investigate the challenges that the pre-service teachers encountered and the professional knowledge they obtained. Conclusion and suggestions were also addressed for teacher training programs.
