新闻组和在线讨论板长期以来一直被用来补充课堂讨论。我们描述了一项研究，比较了 WebAnn 和 EPost 这两个系统的使用，以支持研究生课程中技术论文的课堂讨论。 WebAnn 是一个共享注释系统，支持网页上的锚定讨论，并允许用户轻松地将评论与正在讨论的论文中的特定段落、短语或单词相关联。 EPost 是一个高质量的传统讨论板系统。在我们的研究中，学生使用 WebAnn 对在线讨论的贡献几乎是其两倍。 WebAnn 还鼓励不同的讨论风格，重点关注论文中的具体观点。我们希望 WebAnn 讨论能够作为课堂上深入讨论的起点；但事实上，在线讨论常常与课堂讨论相互竞争。我们总结了这项研究对技术设计及其使用过程的影响。
Newsgroups and online discussion boards have long been used to supplement class discussions. We describe a study comparing the use of two systems, WebAnn and EPost, to support class discussion of technical papers in a graduate course. WebAnn is a shared annotation system that supports anchored discussions on web pages, and allows users to easily associate comments with a particular paragraph, phrase, or word in the paper being discussed. EPost is a high-quality conventional discussion board system. In our study, students contributed almost twice as much to the online discussion using WebAnn. WebAnn also encouraged a different discussion style, focused on specific points in the paper. We expected WebAnn discussions to serve as a starting point for in-depth discussions in the classroom; but in fact, online discussions often competed with classroom discussions. We conclude with implications of the study for technology design and the process of its use.
