This document summarizes a study that investigated factors contributing to speaking-in-class anxiety among Chinese ESL learners in Hong Kong. The study involved a questionnaire completed by 313 first-year university students. Factor analysis identified five main factors: speech anxiety and fear of negative evaluation, comfortableness speaking with native speakers, negative attitudes towards English class, negative self-evaluation, and fear of failing class. The results showed that negative self-evaluation was an important factor leading to speaking anxiety. The conclusion suggests these findings could apply to other non-Chinese language learners as well.
