【中文摘要】:

VR全景视频是近几年新兴的视频类型和学习资源,其学习方式主要包括两种,即直接观看和使用头戴式显示器观看,但两种方式的学习效果是否存在差异以及各自的优缺点是什么亟待人们的探索。VR全景视频能够呈现出360度全景画面,具有虚拟现实的沉浸性、交互性和构想性特点,对于情境化学习、空间认知学习、虚拟学习环境构建等具有重要的意义。以空间认知学习为例,对基于全景视频的教育实验进行了等组实验设计,直接学习组与使用头戴式显示器学习组分别选择了30名在校生作为被试,实验数据测量分两个阶段:在观看全景视频的学习过程中进行空间认知的测量,学习完成后进行知识掌握、学习心理感受以及认知负荷的测量。实验研究结果表明:两种学习方式在空间认知、学习心理感受上具有显著性差异,而在知识掌握、认知负荷方面不存在显著性差异。


【英文摘要】:

Virtual Reality (VR) panoramic video is a sort of emerging video type and learning resource in recent years. Direct viewing and head-mounted display viewing are the two main learning methods. However, whether there are differences between the effects of the two learning methods and what are their respective advantages and disadvantages need to be explored. VR panoramic video can present 360-degree panoramic images, which has the features of immersion, interaction, imagination of virtual reality. Those features are of great significance for situated learning, spatial cognitive learning and virtual learning environment construction. Taking spatial cognitive learning as an example, the equal group experiment of VR panoramic video is designed. The direct learning group and the head-mounted display learning group select 30 students as research subjects respectively. The experimental data are measured in two stages: the spatial cognition is measured during the learning process of viewing panoramic video; knowledge mastery, psychological feelings of learning and cognitive load are measured after students' completion of learning. The experimental results show that there are significant differences between the two learning methods in spatial cognition and psychological feelings of learning, while in knowledge mastery and cognitive load there is no significant difference.
