Development and Evaluation of Quality Assurance System for Digital Content

本文收集了有关数字内容质量保证体系方法的文献，开发了数字内容质量保证体系REAS，并对其进行了评价（实时评估辅助系统）作为数字内容质量保证系统的一部分。该系统用作数字和电子学习内容评估、远程学习内容协作评估、同步学习环境的实时反馈和各种评价项目的积累与共享。利用REAS的功能和RealPlayer的真实的实时通信功能，我们开发了一个名为Streaming-REAS的创作系统。该系统使我们能够链接和进行各种评估和测试调查与流视频的基础上，自动随机排序，显示在浏览器上的任何预设时间的响应页面，同时播放电影文件。在本文中，我们将阐明这个新系统的结构，并解释创作过程如何工作。本文还讨论了使用该系统后的学习效果的验证结果，同时显示了学习者对该系统的高度肯定。

We collected some literatures of method of quality assurance system for digital content.We developed and evaluated the REAS (Real-time Evaluation Assistance System) as used for a quality assurance system for digital content.This system is used as support tool for evaluation of digital ＆ e-learning content, collaborative evaluation of distant learning content, real-time feedback of synchronous learning environments and accumulating and sharing of various evaluation items.Using the functionality of REAS with the real time communication features of RealPlayer, we have developed an authoring system called Streaming-REAS. This system enables us to link and conduct various evaluations and testing surveys with streaming video by automatically, on the basis of random sequencing, displaying a response page at any preset time on a browser while a movie file is played. In this article we will clarify the structure of this new system and explain how the authoring process works. This article also deals with the results of verification of learning effects after using this system while showing a high degree of affirmative recognition toward the system from learners.
