基于视觉认知特征的网课界面布局设计研究

Layout Design of Online Course Interface Based on Visual Cognitive Features

目的 探究网络课程教育的教学效果。方法 以大学思政网课为研究对象,结合个体视觉认知特征归纳出三种典型网课界面布局,通过实验采集被试者在不同网课界面布局中的眼动数据、绩效数据及问卷数据。结果 网课界面布局中文字的左右分布更能吸引被试者的视觉注意力,从而产生更好的学习效果;网课界面布局中教师人像因素会对被试者的凝视时间、凝视次数等眼动数据产生显著影响(P<0.05);教师的眼神与肢体动作会有效吸引被试者的注意力,形成更多的凝视时长与凝视次数,从而达到更好的学习效果;问卷数据也进一步表明,被试者对有教师存在的网课界面布局评价更高。结论 该设计为网课教育教学的发展提供了科学的理论参考。

The work aims to explore the pedagogical effectiveness of online course education.With the online ideo-logical and political course offered by universities as the research object,three typical online course interface layouts were summarized combined with individual visual cognitive characteristics,and the subjects'eye-movement data,performance data and questionnaire data in different online courses interface layouts were collected through experiments.The left-right distribution of text in the online course interface layout was more likely to attract subjects'visual attention,resulting in a better learning effect.The teacher's portrait factor in the online course interface layout had a significant effect on subjects'gaze duration,gaze frequency and other eye-movement data(p<0.05).The teacher's eyes and body movements effectively attracted subjects'attention,resulting in more gaze duration and gaze frequency as well as a better learning effect.The questionnaire data further indicated that subjects rated the layout of the online course interface more highly when the teacher was present.The research provides scientific and theoretical recommendations for the development of online education and teaching.
