中文简介:
视频文档为e-learning提供了强大的支持,在某些情况下甚至构成了提议内容的核心。然而,视频仍然是一种特殊的媒介,它缺乏更容易在文本中找到的特性,例如结构或有意义的索引。这限制了学习者和教师对它们的操作方式。克服这些限制的一种方法是定义、管理和利用视频注释。在本次演讲中,我们首先定义了什么是视频注释,然后重点介绍了视频注释可用于增强在线学习相关过程的各种方法,包括用于专用(主动学习、共享)、协作、课程改进、课程检索和构建等。我们提供了当前系统的一些示例,然后提出了一些与模型和平台相关的技术问题来管理和使用注解。最后,我们介绍了最近推出的CominOpenCourseware(COCo)项目和我们打算做的工作。
课程简介: Video documents provide a great support for e-learning, and in some cases even constitute the core of the proposed contents. Yet video remains a particular medium that lacks properties that can be found more easily in texts, such as structure or meaningful indexing. This limits the way they can be manipulated by both learners and teachers. One way of overtaking these limitations consists in defining, managing and harnessing video annotations. In this talk we first define what precisely are video annotations, before highlighting various ways in which they can be used to enhance elearning-related processes, be it for appropriation (active learning, sharing), collaboration, course improvement, course retrieval and building, etc. We provide several illustrations from current systems, and then address some technological issues related to models and platforms to manage and use annotations. Lastly, we present the recently launched CominOpenCourseware (COCo) project and the work we intend to do.
