弹幕视频中的学习交互分析

Enabling learning interaction through “bullet screen” videos

科学技术日新月异,推陈出新,人类的学习方式也发生了重大的变化。"互联网+"时代,基于视频的交互技术——弹幕为在线学习提供了新的交互方式。本研究通过对B站中一门PS课程的弹幕数据进行分析和文本挖掘,发现弹幕在一定程度上有助于促进老师和学习者、学习者和学习者之间的情感交流,缩小学习者、老师之间的距离,增强学习者的社会临场感,减少其在网络学习过程中产生的孤独感。在学习过程中,学习者之间交互的语言特点体现了互联网时代的时空转换,学习者之间就此形成了语言认同。相比传统课堂,弹幕学习中学习者表达情感的方式更为直接,情感交流更加频繁。基于这些发现,希望本研究能够对以后的弹幕学习研究起到抛砖引玉的作用。

Human learning approaches have developed greatly with the ever growing scientific and technological innovations. In the Internet plus era,'bullet screen'video(video with overlaid comments), a videobased interactive technology, has brought a new style of interaction for online learning. Data mining and discourse analysis of the video course for Photoshop on the video website blibli.com indicated that the presence of'bullet screen'helped, to some extent, promote affective interaction between teachers and learners, and among learners too, shorten the distance between teachers and learners, and among learners too, increase the social presence of learners, and lower learners' sense of loneliness during the learning process. Learners' language used in the interaction showed special and temporal dimensions in the Internet era, hence forming a shared language identity. Compared to conventional classroom learning, learners using'bullet screen'videos engage themselves in more direct and more frequent affective exchanges.
