This paper investigates the use and impact of an online discussion forum in a large-scale beginners' Chinese course at the UK Open University. By analyzing both quantitative data from questionnaires and qualitative data from interviews alongside forum interactions, the study explores the nature, patterns, and functions of the forum among distance language learners. Findings reveal that students had a highly positive experience, with the forum serving as a crucial virtual space for support, resource sharing, and communal learning. It fostered a sense of belonging and course cohesion, enhancing the overall enjoyment and effectiveness of the Chinese language learning process.
