数学沉浸式学习环境的设计与实现

The Design and Realization of Mathematics Immersive Learning Environment

数学学习具有抽象化水平高、逻辑关系强和思维能力要求高的特点。数学科普在训练和促进创新性思维方面具有不可替代的作用。沉浸式学习环境使学习者获得良好的学习体验,有益于学习者“身临其境”地体验和学习数学科学知识,促进其对抽象知识的掌握。然而,国内对于数学学科构建高沉浸感、自然交互性的沉浸式学习环境研究还十分稀缺。基于中国科学技术馆的数学科普展项,设计和实现数学学科内容的沉浸式学习环境,提出其总体框架和相关技术,运用基于虚拟现实的沉浸式可视化技术实现抽象数学知识具象化,借助建模软件、3D引擎、虚拟现实设备等实现沉浸式交互体验。最后,通过用户体验评价得出所设计的沉浸式学习环境使学习者获得良好的感官体验和交互体验。

Learning mathematics requires high levels of cognitive skills as it mostly consists of abstract concepts and complex logical relationships. Mathematical science education plays an irreplaceable role in training and promoting innovative thinking and cognition. The immersive learning environment enables turning abstract mathematical concepts and problems into visible items or processes. And learners can learn mathematics through sensory interaction in the immersive learning environment, which promotes their mastery of abstract concepts. However, research for building an immersive learning environment for mathematics learning with high immersion and natural interaction is still very limited. Based on the mathematics science exhibition of China Science and Technology Museum, this study provides an overall framework for developing a mathematics immersive learning environment and uses immersive visualization technology based on Virtual Reality(VR) to reify abstract mathematical knowledge. Users can get an audio-visual interactive experience with VR Head-Mounted Devices(HMD) and controllers. Finally, through the user experience survey, it is concluded that this immersive learning environment can enhance learners’ learning experience for mathematics learning.
