本研究旨從台灣高中生的觀點探討準備英語演講的過程中所遇到的挑戰與其相關對策以及個人成長收穫。本研究採取質性個案研究，研究對象為兩位有不同語言程度的台灣高一學生。分析資料由多重管道蒐集，包含與學生的半結構式訪談，練習時的觀察記錄以及其他相關文件，最後經由對比原始資料得出研究結果。 研究結果顯示，兩位研究對象所面臨的挑戰可分成四大類，分別為單句內的問題、跨句間的問題、口語表達與演說焦慮，其中又以口語表達與演說焦慮為兩大首要挑戰。以語言焦慮而言，焦慮的確對口說有負面影響，然而，它也能對於學習者的表現有正面的影響，如能促使學習者更認真面對比賽。此外，焦慮程度也與語言熟練度有關，擁有較高語言程度的學習者傾向擁有較低程度的焦慮。以口語表達的挑戰而言，兩位學習者所面臨的挑戰皆是與非語言方面的困難，例如站姿、手勢、聲音與面部表情等。此外，學生的個人收穫分別如下所列：(一) 開拓眼界的經驗；(二) 成就感；(三) 其他同儕的認同感；(四)自我實現。研究者根據這些發現，提出相關教學建議及未來研究方向，以期對未來有興趣參與英語演講的師生更多建設性的研究貢獻。 / This study aims to examine what challenges would be confronted, how those challenges were dealt with and what personal growth reaped during the process of preparing for an English speech contest from the perspectives of high school students in Taiwan. A qualitative research method was employed in this case study. Two first-year high school students with different proficiency levels were invited to be the participants of this study. Data were collected through multiple sources, including semi-structured interviews with students, observations of each practice, and other related artifacts. Data were analyzed by constant comparative method. The results showed that the challenges the two participants faced could be divided into four categories, including the intra-sentence level challenges, inter-sentence level challenges, oral delivery and anxiety. Among these challenges, the top two challenges they faced were anxiety and oral delivery. In terms of language anxiety, anxiety did have debilitating effects on speaking; however, it can also have some facilitating influence on learner’s performance such as compelling the participant to face the contest more seriously. Also, the degrees of anxiety have to do with language proficiency. Learners with higher proficiency tended to have lower degree of anxiety. As for the challenges in oral delivery, what the two participants faced is associated with other non-linguistic aspects of speaking, such as posture, gesture, and voice and facial expression. In addition, the personal growth gained from such experience can be listed as below: (a) horizons-broadening experience, (b) a sense of achievement, (c) a sense of recognition from his peers, and (d) a sense of self-actualization. Based on the findings, pedagogical suggestions and direction for future research are provided. It is hoped more insights could be offered to both instructors and students who are interested in taking part in English speech contests.
