Abstract

With digital technology development, online video platforms have become key informal learning spaces. This study examines Bilibili’s high school physics content, analyzing how danmu and comments shape this space through content and topic analysis. Results show the space aligns with the school cycle: danmu fosters emotional interaction, while comments deepen knowledge. Discussions reflect community identity, with highly upvoted comments focusing on summaries, reflections, and resource sharing. User collaboration enhances learning and emotional support but may cause disturbances from danmu overload, misinformation, or off-topic content. Recommendations for platform optimization and user engagement are provided.
