外部视觉情绪设计对多媒体学习的影响

以高中生为被试对象，以大陆漂移论为素材，研究外部视觉情绪设计对多媒体学习的影响。结果表明，接受情绪设计组(实验组)的积极情绪显著高于中性组(对照组)；实验组与对照组内在认知负荷、相关认知负荷均无显著差异，外在认知负荷小于对照组；实验组保持测验成绩显著高于对照组，迁移测验成绩无差异。同时，外部视觉情绪设计能显著提高多媒体学习效果。外部视觉情绪设计的实验设计突破了已有研究300s学习素材的诱发时间，拓展了多媒体学习情绪设计的内涵。

The Influence of External Visual Emotion Design on Middle School Students' Multimedia Learning

Taking high school students as subjects and the theory of continental drift as learning materials, this paper studies the influence of external visual emotion design on multimedia learning. The study found that the positive emotions of the emotional design group(experimental group)were significantly higher than those of the neutral group(control group). There was no significant difference in internal cognitive load and related cognitive load between the experimental group and the control group, and the external cognitive load was smaller than the control group. The results of retention test in the experimental group were significantly higher than those in the control group. The research shows that the external visual emotion design can significantly improve the multimedia learning effect. The experimental design of external visual emotion design breaks through the induction time of 300s of learning materials that have been studied, and expands the connotation of multimedia learning emotion design.
