Abstract

Online learning is gradually becoming a mainstream education method, and instructional video plays an indispensable tool for online learning. In order to improve learning efficiency, more and more studies focus on the design of instructional video content. However, online learning requires video transmission over the network, and instructional videos may become blurred due to bandwidth limitation. In this case, the instructional video content designed to improve learning efficiency will lose its usefulness, and alternative instructional strategies need to be provided to improve learning efficiency when online learning video quality degradation occurs. The experimental results have shown that paper assistant learning materials and audio assistant learning materials with voice cues can solve the impact of video quality degradation and improve learning efficiency.
在线学习视频质量下降时提高学习效率的有效学习辅助策略
在线学习正逐渐成为一种主流的教育方式,而教学视频则是在线学习不可或缺的工具。为了提高学习效率,教学视频内容的设计成为越来越多的研究热点。然而,在线学习需要通过网络传输视频,由于带宽的限制,教学视频可能会变得模糊。在这种情况下,为提高学习效率而设计的教学视频内容将失去其有用性,当在线学习视频质量下降时,需要提供替代的教学策略来提高学习效率。实验结果表明,纸质辅助学习材料和带有语音提示的音频辅助学习材料可以解决视频质量下降的影响,提高学习效率。
