研究依据互动仪式链理论、教育学、社会心理学等理论，以在线开放课程“教育学”在哔哩哔哩网站上所装填的弹幕文本为研究对象，采用定性与定量相结合之研究方法，利用自然语言处理技术对网站的弹幕进行爬取分析。发现在线教学过程中“学习主体再创能力强、教学主体探究动力足、教学过程互动频率高、教学反馈正向评价高”，但也存在着“偏离预设目标隐患急待正视、探究意愿的稳定性有待维持、参与主体的多元性有待夯实、反馈对象的先进性急需赋能”等挑战，建议通过“引导+疏导、高阶+挑战、预设+陪伴、温度+亮度”等策略来提升在线教学的质量，回应“在线教学的质量效果究竟如何”等质疑。
【英文摘要】：
Based on theories of interactive ritual chain, pedagogy, social psychology, etc., this study takes the bullet screen text of the online open course "Pedagogy" loaded on the Bilibili website as the research object, combines qualitative and quantitative research methods to crawl and analyze the bullet screen of the website using natural language processing technology. It was found that in the process of online teaching, “the learning subject has a strong ability to recreate; the teaching part has sufficient motivation to explore; the frequency of interaction in the teaching process is high; and the positive evaluation of teaching feedback is high ". However, there are also challenges such as "the deviation from the predetermined goal which needs to be faced, the stability of the willingness to explore which needs to be maintained, the diversity of the participating subjects which needs to be consolidated, and the advanced nature of the feedback objects which needs to be empowered". It is suggested that the quality of online teaching should be improved through strategies such as "guidance + facilitation, high-level + challenge, preset + company, temperature + brightness" to respond to questions such as "what is the quality and effect of online teaching?".
