英語已被公認為全球的國際共通語言；然而，在缺乏英語練習的學習環境下，
以英語為外語(English as Foreign Language, EFL）的學生較少有機會練習口說。虛擬實
境技術的普及，讓學生可以藉由科技的幫助，在情境中學習。本研究應用了環景影
像虛擬實境 (Spherical video-based virtual reality, SVVR)，提供學生一個模擬真實情境
的英語交流環境；同時，透過同儕互評策略的應用，引導學生學習評估同伴的口說
表現並做出反思。為了檢驗研究方法的有效性，本研究採準實驗設計，將兩個班級
共 69 名學生分配到實驗組和控制組。實驗組學生在 SVVR 環境中學習並採用同儕
互評策略，而控制組學生在一般的SVVR環境中學習，並由教師提供回饋。由研究
結果發現，本研究提出的方法，顯著地提升了學生英語口說表現、學習動機、批判
性思維能力，同時降低了英語學習焦慮。

English has been recognized as a means of communication in the globe. However, owing to the lack of realistic English practicing contexts, EFL (English as Foreign Language) students generally have few opportunities to communicate with people in English, including speaking as well as interpreting and identifying what they have heard. In this paper, a spherical video-based virtual reality (SVVR) environment is developed to situate students in authentic English oral contexts; moreover, a peer assessment strategy is employed for guiding the students to learn to evaluate peers’ oral presentation and make reflections. To evaluate the effectiveness of the proposed approach, an experiment was conducted with a total of 69 students assigned to an experimental group and a control group. The students in the experimental group learned employing a peer assessment strategy in the SVVR environment, while those in the control group learned in the SVVR environment without peer assessment. It was found that the proposed approach significantly improved the performances of the students in terms of English oral presentation, learning motivation, critical thinking skills as well as reducing their English learning anxiety.
