【摘要】 随着世界网络技术的不断进步,以及Web2.0理念的进一步推广,国内外的视频共享平台的建设愈加成熟。无论是视频上传中的文件大小及支持格式的限制条件方面,还是网络带宽不足导致的视频播放需要长时间等待方面,都已经不再是制约其发展的主要问题。但是纵观国内已有的各大视频共享平台,都没有把教育视频的共享作为平台发展的重点之一,有所涉足的几个视频分享平台在教育视频的建设方面都存在着较为明显的缺陷。这其中的主要原因可以归结为以下几点：一方面,由于面向的对象人群的层次多样,以及视频内容的数量庞大,教育视频在内容的分类上要想做到全面存在一定的难度；另一方面,教育视频受限于视频的质量及版权问题,很难实现商业网站期望的经济效益等。这些都在一定程度上制约了我国广大教育工作者和学习者在一个开放的平台寻找和使用这一更为有效地信息传播媒体——教育视频。我们应该如何利用已有的技术手段来帮助我国的教育工作者和学习者更好的利用教育视频这一最佳的教育信息传播媒体?如何帮助他们实现更好的教育教学和学习效果?怎么样才能促进更多的优秀教育视频的出现?这也是本研究所想解决的主要问题。本研究尝试以系统论作为方法论来指导整体研究,综合运用了文献分析法、内容分析法、归纳总结法等研究方法,对国内外现有的视频分享平台进行了综合比较分析。通过分析找出国内已有的视频平台在教育视频分类方面的不足,并参考借鉴国外一些优秀的教育视频平台的优缺点,从而整理出一套基本能囊括我国各教育类视频的分类体系。同时本着促使教育工作者和学习者更好的利用教育视频进行教育学习的想法,笔者提出了一些对应的功能模块,并尝试去实现。基于上述的选题背景和研究思路,全文由以下几部分组成：第一部分是绪论。阐述了本研究问题的提出背景、国内外研究现状、理论基础与相关概念、研究目的和意义；第二部分是国内外视频平台的比较分析。对国内外现有的视频分享平台进行了综合的比较分析,通过这些分析得出本教育视频平台开发的必要性和可行性。从而整理出笔者认为的比较科学合理的教育视频分类系统。此外,笔者还重视了教育工作者和学习者在使用教育视频平台的时候可能需要的支持服务,提出构建了视频互动系统和多媒体辅助学习系统。通过对平台功能的不断完善,描绘出一个较为完整的教育视频平台的框架。第三部分是教育视频平台的平台设计。鉴于笔者在技术方面的不足,所以只选取了力所能及的几个功能模块进行了实现,证明了该教育视频平台框架的可用性。第四部分为教育视频平台的实现。笔者就已实现的功能进行了阐述,基本达到了设计初期预想的效果,经过小范围的测验能够较好的运行。第五部分是总结和展望,总结本研究所做的工作,提出尚待解决的问题,以及希望未来能够继续进行的研究内容。通过对现有平台的综合比较分析,参考借鉴较为成功的案例,以及自己的实践研究,笔者认为本研究不仅为我国当代教育视频的推广运用研究挖掘了新的研究重点,而且对我国当前面临的教育视频数量庞大、分类混乱、质量良莠不齐、缺乏完善的管理体系提供了一定的解决办法。更多还原

【Abstract】 With the continuous progress of the network technology, as well as the further promotion of Web2.0, the building of video sharing platform is becoming more mature from home and aboard. The video upload file size limits, conditions of supported formats, or inadequate network which needs video player to take a long time to wait for connection, are no longer the main problems that restrict the development of video sharing platform. However, throughout the country, the major video sharing platforms existing haven’t treated the educational video sharing platform as a key part. And there are obvious flaws in several video sharing platforms involved in the education. The main reasons are as follows:on the one hand, due to the diversity of audience, and the large number of video content, there is a certain difficulty in the comprehensive classification of educational video content; On the other hand, it is difficult to achieve the copyright issues. All mentioned above restrict the majority of educators and learners to find and use educational videos as an information media more effectively in an open platform. How should we use the existing techniques to help educators and learners with better use of educational videos as the best educational information communication media? How to help them achieve better teaching and learning? How to promote more good educational video appear? This is the major problems this research wants to solve.This study attempts to use dynamic systems theory as a methodology to guide the overall study, including the integrated use of the document analysis, content analysis, summarization and other research methods, and comprehensive comparative analysis of the existing domestic and foreign video sharing platforms. After the analysis of the domestic video platforms’drawbacks, and the advantages and disadvantages of video platforms abroad, this paper will summarize a set of basic classification system including the whole education class video. At the same time, this paper will make a number of the corresponding function models to help educators and learners with a better use of educational videos for education and learning ideas. Based on the ideas mentioned above and research topic ideas, the paper consists of the following components:The first part is an introduction, which describes the background of the problem, research status, theoretical basis and related concepts, purpose and meaning;The second part is the comparative analysis of domestic and international video platform. I did a comprehensive comparative analysis between existing domestic and foreign video sharing platform. I draw a conclusion on the basis of this analysis about the need and feasibility for education and video platform. In addition, I also paid attention to the support services which educators and learners may need in the use of educational video platform. In the end, I’ll paint a more complete framework for the education screen platform.The third part is the design of the education video platform. As for the technical deficiencies, I selected only a few function modules to achieve, and show that the availability of educational video platform framework.The fourth part is the realization of educational video platform. I elaborated on the function was already achieved. The basic design has achieved the desired results, has run steadily after a small-scale tests.The fifth part is a summary and outlook. I summarized the work done in this study, as well as put forward the issue to be resolved, and hope would continue in the future.Through a comprehensive comparative analysis of the existing platform, together with a reference of the successful cases, and my own practical research, I believe the study of promotion of the modern educational video not only raise a new research focus, but also come up with a solution for the educational videos which is facing a classification confusion, quality variance, and a lack of a sound management system.更多还原
