摘　　要：随着新冠肺炎感染在全球范围内的持续发展以及局部地区的疫情反复,在线教育的学习模式得到进一步的深入推广和广泛应用。当前主流的在线教育模式主要通过专门的应用程序,如智慧树、雨课堂、云课堂以及腾讯会议等传统在线方式实现,目前还没有通过Web浏览器的B/S模式进行通信的免费、高质量的完整解决方案。研究当前在线学习系统中存在的依赖于专门App、学习模式单一、学习者之间互动性不足等问题,针对服务器上实现基于WebRTC的web-Skyclass系统。该系统通过不同的多媒体控制方式提供问答模式、论文答辩和课堂直播等多种实际场景的不同学习模式,为学习者提供文字、视频、音频的多种学习场景和互动方式。基于这些媒体控制设计了一个具有用户友好界面的系统,在此基础上进行实验以评估所提控制方式支持的系统的有效性和实用性。With the continuous development of the New Crown Pneumonia infection globally and the recurrence of the epidemic in localized areas,the learning mode of online education has been further promoted in depth and widely used.The current mainstream online education mode is mainly realized through specialized apps,such as Wisdom Tree,Rain Classroom,Cloud Classroom,and Tencent Conferencing and other traditional online methods,and there is no free,high-quality and complete solution for communication through the B/S mode of Web browser.We study the problems of relying on specialized apps,single learning mode,and insufficient interactivity among learners in the current online learning system and aim to implement the web-Skyclass system based on WebRTC on the server.The system provides different learning modes for a variety of practical scenarios such as question and answer mode,thesis defense and classroom live broadcast through different multimedia control methods and provides learners with a variety of learning scenarios and interaction methods in text,video and audio.A system with user-friendly interface is designed based on these media controls,and experiments are conducted on this basis to evaluate the effectiveness and practicality of the system supported by the proposed controls.
