基于数字孪生讲台的在线沉浸式教学体系分析与流程设计

随着新技术的迅猛发展,“大数据+AI”已成为现代社会一种新的驱动力和思维方式。一种可有效实现物理世界和信息世界智能互联与交互融合的新技术——数字孪生应运而生。基于数字孪生技术,可构筑联通现实教学空间与虚拟教学空间的数字孪生讲台,并成为在线教学空间的“数字大动脉”。数字孪生讲台可分为在线学习特征分析技术和虚实教学空间融合分析技术,通过“在线教”与“在线学”间的深度融合、映射与镜像,能为在线沉浸式教学注入新的数字生产力。基于此,从教学、技术两方面,探索数字孪生讲台的在线沉浸式教学流程设计与技术运用,即基于混合式平台的教学数据采集与管理,基于多维分析的教学数据分析与建模,基于精准教学和精准管理的数据应用,基于增强现实技术的在线沉浸式教学体验,进而设计其教学流程。旨在通过数字孪生讲台的多源数据融合、虚实融合映射、教学服务融合优化,促进数字化、智能化课堂的形成,推动数智融合在教学方面的创新性应用,从而形成一种基于大数据的课堂数据互动、映射的新形态,进而革新与重塑现代教育体系。

Research on Online Immersive Teaching System Analysis and Process Design based on Digital Twin Platform

With the rapid development of new technologies,“big data+AI”has become a new technology and a way of thinking in modern society.One of them is digital twin technology,a new technology that can effectively achieve the intelligent interconnection and interaction of the physical world and the information world.Based on digital twin technology,the digital twin platform connecting the real teaching space with virtual teaching space can be built and become the“digital artery”of the online teaching space.Digital twin platform is divided into online learning features analysis technology and space fusion analysis technique of virtual and real teaching.It focuses on the deep integration as well as the mapping and image of“online teaching”and“online learning”,injecting new digital productivity into online immersive teaching.From two aspects of teaching and technology,therefore,this study explored the design of online immersive teaching process and technology application based on digital twin platform,namely the teaching data acquisition and management based on a hybrid platform,teaching data analysis and modeling based on multidimensional analysis,data application based on precision teaching and precision management,and online immersive teaching experience based on augmented reality.Through multi-source data fusion,virtual-real fusion mapping and fusion optimization of teaching and service,the digital twin platform can promote the generation of new forms of digital and intelligent classroom and the innovative exploration of digital and intelligent integration in teaching,so as to create a new form of classroom interaction and mapping based on big data,and then innovate and reshape modern educational system.
