促进学习还是干扰学习——弹幕对学习影响的元分析

弹幕(Danmaku)作为在线视频课程中的一种新型交互方式,能够让学习者与视频内容实时互动,因而受到广大学习者和研究者的关注。为了探讨弹幕是否能够真正促进学习发生,文章采用元分析的研究方法,对生成的25个效应量(被试2578人次)进行分析,考察弹幕对学习过程及学习结果的影响。研究结果表明:(1)弹幕对学习者学习的总效应量显著,弹幕对学习过程的影响不显著,弹幕对学习结果的影响显著;(2)弹幕嵌入的视频时长对学习过程及学习结果没有预测作用;(3)视频课程的知识类型、弹幕类型及有无字幕对弹幕影响学习过程及学习结果不起调节作用。

Facilitating Learning or Interfering Learning: A Meta-analysis of Impact of Danmaku on Learning

Danmaku, as a new interactive mode in online video courses, enables learners to interact with video content in real time, so it has attracted the attention of many learners and researchers. In order to explore whether the Danmaku can really promote the occurrence of learning, this paper adopts the research method of meta-analysis to analyze 25 generated effect quantities(2578 subjects) to investigate the impact of Danmaku on learning process and learning outcomes. The results show that:(1) the Danmaku has a significant total effect on learners' learning, The Danmaku has no significant effect on learning process, while it has a significant effect on learning outcomes;(2) The video duration embedded in Danmaku has no predictive effect on learning process and learning outcomes;(3) The knowledge types, Danmaku types and the presence or absence of subtitles of video courses have no regulating effect on the influence of the Danmaku on learning process and learning outcomes.
