基于眼动信息分析的多媒体教学优化设计

Multimedia teaching optimization design based on eye movement information analysis

针对优化与高校学生密切相关的课堂教学质量问题,选择30名视力正常的大学生作为被试,采用眼动跟踪系统记录被试在阅读同样内容的文字版、图片版、视频版教学课件设计过程中的眼动信息,对获取的人体眼动数据进行处理及综合分析。结果表明:1墨蓝字体比红色和粉色字体更具有吸引力,宋体、仿宋或楷体等字体产生的阅读效果更好,每页幻灯片字数建议在150字以内且字号大于40。2添加图片有助于提高学生的注意力,但图片的大小及数量需要控制,图片过大会影响学习效果。3在多媒体教学中适当增加动画或视频设计,可以突出教师所要传达的重点教学内容,提高学生的注意力和兴趣度,从而达到良好的教学效果。研究结果为改善多媒体教学课件、提高课堂教学质量提供了参考依据。

Ink blue font is more attractive than red and pink, Song typeface, hnitation Song typeface and Regular script have better reading effect. In each page, the number of PF＇T words less than 150 and the font size larger than 40 is suggested. 2.
