立体3D、2D视频对大学生学习效果的影响

The Impact of Stereoscopic 3D and 2D Videos on University Students’Learning Effects

为了探究立体3D视频相较于传统2D视频能否更好地支持学习,文章以72名大学生为研究对象,进行了"2(两种视频呈现方式)×2(两种空间认知能力)"的两因素随机实验,结果显示:视频呈现方式对主要眼动行为没有显著影响,但对学习成绩、认知负荷与学习心理感受有显著影响;空间认知能力与视频呈现方式在主要眼动行为、学习成绩、认知负荷和学习心理感受方面均不存在交互影响。研究结果并不支持立体3D视频相较于2D视频在学习效果上存在显著优势,故文章建议教师与学生应针对不同的教学、学习需要,选择合适的数字资源和信息技术工具。文章的研究结论可为3D显示技术在教学中的有效应用提供参考。

In order to explore whether stereoscopic 3D video could better support learning compared with traditional 2D video,the paper took 72 university students as research objects and conducted a two-factor random experiment of 2(video presentation mode)×2(spatial cognitive ability).The results showed that the video presentation method had no significant impact on the main eye movement behavior,but it had significant impacts on academic performance,cognitive load and learning psychological perception.Meanwhile,it was found that there was no interactive influence between spatial cognitive ability and video presentation mode on the main eye movement behavior,cognitive load,learning achievement and learning psychological perception.The research results did not support the significant advantages of stereoscopic 3D video in the learning effect as compared with 2D video.It was recommended that suitable learning resources and information technology tools should be selected for different teaching and learning needs.It was suggested that appropriate digital resources and information technology tools should be selected according to different learning needs.The research conclusion of this paper could provide reference for the effective application of stereoscopic 3D technology in teaching.
