本文探討英語學習者對成功學習及其所意識到自身能力不足處的看法。此項研究對台灣一所大學109 位新生進行了問卷調查，其中14 人並接受了焦點小組訪談。問卷結果顯示，學生所列出促成成功學習的因素多為情意相關因素，且學生把這些因素列成遠重要於其它因素(包括語言天賦和學習策略)。後續的焦點訪談結果則是突顯出學生感到自身對社會語言學知識的缺乏及其英語口說焦慮。此研究的發現將可幫助英語教學工作者改進其教學規劃。 This study examined EFL learners’ views on what it takes to effectively learn a language and their own perceived deficiencies as learners. In the study, 109 freshmen at a Taiwanese university were surveyed, and 14 of them were interviewed in focus groups. Among the factors they listed in the questionnaire, the students perceived a variety of affect-related factors as more important for successful learning than other factors they added low on the list such as aptitude and learning strategies. The follow-up focus group interviews then highlighted the students’ perceived deficiencies as a lack of sociolinguistic knowledge, and also anxiety when speaking. It was concluded in the paper that knowing the information gleaned from this research could help instructors improve their teaching practices.
