基于增强现实技术的立体化教材研究与开发

Research and development of three-dimensional teaching materials based on augmented reality technology

教材作为教学活动的基本工具,是沟通教师教与学生学的桥梁.为优化教学活动和提高教学时效,提出建设AR立体化教材来搭建沉浸式学习环境.利用微视频技术开发了AR微课;依托大数据技术和网络教学资源构建了智能习题库;基于Unity3D和EasyAR虚拟现实API创建立体模型并开发移动增强现实教学实践应用,使传统教材中二维内容三维立体化展示,尤其是实现了斜二测几何图形的立体化呈现.在高中数学课实践AR立体化教材的多种技术,表明教材为营造个性化和沉浸式教学环境提供了介质基础,有助于提高知识转化率和学生学习兴趣,具有良好的价值和意义.

As a basic tool of teaching activities,teaching materials are the bridge between teachers and students.In order to optimize teaching activities and improve teaching effectiveness,AR three-dimensional teaching materials are proposed to build an immersive learning environment.AR micro course is developed by using micro video technology.Relying on big data technology and network teaching resources,an intelligent exercise bank is constructed.Based on Unity3 d and EasyAR virtual reality API,the three dimensional model is created and the practical application of mobile augmented reality teaching is developed,which makes the three-dimensional display of two-dimensional content in traditional teaching materials,especially the three-dimensional presentation of oblique two survey geometry.The application of AR three-dimensional teaching materials in high school mathematics shows that teaching materials provide media basis for creating personalized and immersive teaching environment,which is helpful to improve knowledge conversion rate and students’interest in learning,having good value and significance.
