教学PPT插图颜色及布局规律的实验研究

An Experiment on Illustration Colors and Layouts of Educational PowerPoint

PPT是目前教学活动中最常用到的媒体,而插图是构成教学PPT的重要元素,良好的插图设计可以引导学习者注视,提高学习者学习效率。本文通过眼动实验法探究不同插图颜色和布局方式对于学习者的影响。实验发现,彩色插图PPT的眼动指标优于黑白插图,然而后测成绩未发现显著差异,表明插图颜色并未影响信息传递效果,但能更好地激发学习者兴趣。另外,研究发现插图的不同布局方式(上、下、左、右)对于眼动指标也产生了影响,学习者表现出了一定的注视偏好。基于发现的规律,本文提出了教学PPT设计的几个策略。

PowerPoint is the most widely used media in instruction and the illustration is an important component of PPT. Well-designed illustrations could attract student's attention and enhance learning efficiency. In this research,eye tracking system is used to record the eye movement indexes of college students when they are reading PowerPoint with different illustration colors and layouts. The results show that the related eye movement indexes of the color illustration are significantly better than the black-white illustration. However,no significant difference was founded in the test scores, indicating the color only enhanced the motivation of the subjects. The location( up,down,left, right) of illustration influenced the eye movement indexes of the subjects. The eye-tracking data shows the students have some attention preferences. According to the experiment result,advices are given for better design of educational PowerPoint.
