1 INTRODUCTION
CURRENT e-learning systems focus on supporting the
creation and presentation of learning materials.The
communication between the learners,which is also an
important factor for a successful learning experience [1],is
not taken into account seriously enough in today’s
E-Learning systems.
Discussion fora provide unique communication features,
which make them a perfect candidate for handling communication
in an e-learning environment:Forums allow for
asynchronous communication,and hence,do not force
learners to negotiate for specific communication times as this
would be required in chats.Furthermore,as all exchanged
knowledge is stored within a forum,it can be explored or
searched by all users at any time.This could possibly give an
immediate answer for frequently asked questions.
Another strong benefit of discussion fora is the tree-like
structure.While a discussion forum usually has an overall
topic,user can further divide the forum into subfora where
specific subtopics can be discussed.Within the subfora,
different discussions can be distinguished by so-called
threads.This structure enables learners to browse through
discussion topics quickly and further to navigate directly to
relevant topics.Thus,users are not overwhelmed by
unrelated information as this could happen in mailing lists
where users can only decide to opt-in and receive all mails
or opt-out and receive none of the mails.
Drawbacks of the structure arise when 1) users start a
discussion in a wrong thread,2) a topic would fit in
multiple threads,or 3) the forum becomes so big that the
structure can not be overlooked by the users.In such a case,

1介绍
当前的电子学习系统重点扶持
创造和表达的学习材料.这
学习者之间的沟通,也是一个
重要的因素对一个成功的教学经验[1]
不考虑在今天的足够的重视
电子学习系统.
论坛讨论提供独特的沟通特点,
使他们的完美候选人处理沟通
电子学习环境:论坛允许
异步通讯,因此,不要勉强
学习者为特定的通信倍谈判
将被要求在聊天.而且,当所有交换
知识是存储在一个论坛,它可以探测或
所有用户搜索.这可能给一个
立即回答为经常被问到的问题.
又有强烈的好处是树讨论论坛
结构.当讨论论坛通常有一个全面的
话题,用户可以进一步划分成subfora论坛的地方
特定的主题可以商量.在subfora,
不同的讨论可以辨识所谓了
螺纹.这个结构使学习者浏览
很快,并进一步讨论题目直接航行
相关主题.因此,用户没有被打倒
不相关的信息,因为这可能发生在的邮寄名单中
玩家只能决定选择、接受一切做到
或“选择退出”和接受所有的邮件.
结构中存在的不足之处时出现的1)玩家开始
讨论在一个错误的线程,2)主题能融入新环境
多线程,;(3)论坛变得如此大,
搭建无法被广大用户.在这种情况下
