Research on the Cultivation of High School Mathematics Stereoscopic Geometry Space Concept under Virtual Reality (VR) Technology

基于高中新课改后对立体几何教学方面所考察的重难点，通过构建VR技术支持的高中立体几何教学模式，探索技术赋能下空间观念培养的理论路径与实践策略。方法上采用设计研究法，通过三轮迭代开发VR教学案例，结合学生培养发展方向与目标，提炼核心设计原则。最终提出“三维具象化–动态交互–抽象内化”的VR教学框架，形成关键设计策略与典型应用场景。最终以VR技术通过多模态感官协同与认知具身化，有效突破高中生复杂空间问题的认知瓶颈。Based on the key and difficult points examined in the teaching of solid geometry after the new curriculum reform in high schools, by constructing a teaching model of solid geometry in high schools supported by VR technology, the theoretical path and practical strategies for cultivating spatial concepts empowered by technology are explored. Methodologically, the design research method was adopted. VR teaching cases were developed through three rounds of iterations. Combined with the direction and goals of students’ cultivation and development, the core design principles were refined. Finally, a VR teaching framework of “Three-dimensional visualization-Dynamic interaction-Abstract internalization” was proposed, forming key design strategies and typical application scenarios. Ultimately, through multi-modal sensory collaboration and cognitive embodiment with VR technology, the cognitive bottleneck of complex spatial problems among high school students is effectively broken through.
