【摘要】：随着现代计算机网络技术的发展,互联网技术在教育教学领域中的应用也日益广泛与深入。网络教育、网络课程、在线教学与网络学习环境的设计已经成为当前国际教育界的热门话题,这在一定程度上有效地推动了网络教育教学的发展。在教育的形式方面,网络教学视频已是教师进行网络教学和学生进行在线学习的最主要数字资源。在当前网络课堂教学中,不管是一般的课程教学网站还是目前热门的MOOC或SPOC课程等学习平台,播放的学习视频一般都是教师的讲授视频与教学课件的相互配合。学习者观看这样形式的视频资源就相当于将传统的教学形式搬进了视频中,学生不是学习的主动者,依然是知识被动的接收者。同时,学习平台中视频播放的单一形式,导致学习者只是简单地观看视频并没有强烈的学习兴趣。因此,在线学习的学习效果没有得到进一步的提升,这对高等教育的网络化、数字化带来很大不便。本课题的研究首先对国内外在线学习平台上的学习资源中视频的播放情况,以及学习者在学习过程中的视频播放流程进行了调查,例如:学堂在线、慕课网、华文慕课和中国大学MOOC等知名学习网站。笔者通过文献调查了解分析了国内外针对于在线视频播放过程中采取的行为和技术手段,并发现其存在的不足与缺陷。通过HTML5+jPlayer技术手段,笔者对在线学习中视频的播放进行了控制,再加上沉浸主义理论、在线学习反馈理念和联通主义学习理论中关于在线学习平台的研究,笔者设计并实现了一个在线学习平台。本系统模块可以基于网络学习平台使用,也可以单独为网络视频控制提供服务。系统开发与实现架构是依据了 Strus2 MVC分层设计思想,并使用了 Mysql作为系统平台的数据库。前端页面采用HTML5+jQuery+jPlayer库,通过自身设计与实现控制视频播放的逻辑算法,系统最终实现了基于HTML5视频控制的在线学习系统模块。此外,视频播放逻辑控制的实现算法也可以为移动端的应用提供参考价值。
[Abstract]:With the development of modern computer network technology, the application of Internet technology in the field of education and teaching is becoming more and more extensive. The design of online teaching and online learning environment has become a hot topic in the international education circle, which to some extent has effectively promoted the development of online education and teaching. The online teaching video is the most important digital resource for teachers to teach online and students to learn online. In current network classroom teaching, no matter it is a general course teaching website or a popular learning platform such as MOOC or SPOC courses, Generally speaking, the learning video broadcast is the cooperation between the teacher's teaching video and the teaching courseware. The learner watching this kind of video resource is equivalent to moving the traditional teaching form into the video, and the student is not the active learner. At the same time, the single form of video playing in the learning platform causes the learners to simply watch the video and have no strong interest in learning. The effect of online learning has not been further improved, which brings great inconvenience to the networking and digitization of higher education. And the process of playing video in the process of learning, such as online classroom, Motule.com. Through literature investigation, the author analyzes the behavior and technical means adopted in the process of online video playback at home and abroad. By means of HTML5 jPlayer technology, the author controls the playback of video in online learning, plus the theory of immersion. The author designs and implements an online learning platform based on the theory of online learning feedback and Unicom learning theory. The system module can be used on the basis of network learning platform. The system development and implementation framework is based on the Strus2 MVC hierarchical design idea, and uses Mysql as the system platform database. The front-end page uses HTML5 jQuery jPlayer library. By designing and implementing the logic algorithm to control video playback, the system finally realizes the online learning system module based on HTML5 video control. The realization algorithm of video playback logic control can also provide reference value for mobile applications.
