摘要：随着网络技术的发展，BBS论坛为人类群体交流互动提供了新的环境，因而应用越来越广泛。校园BBS论坛同样也方便了大学生之间进行知识探讨、信息交流、放松娱乐。本文旨在探究大学BBS学习讨论区中交互特性和群体特征。通过使用内容分析法和社会网络分析法对“扬帆南师大校园BBS”中的“电脑技术”学习讨论区进行了分析。研究结果表明，该学习讨论区中学习者对新知识的建构大多处于较低阶段，但交互能够得到及时反馈，并且大多数主题帖的发帖者和回帖者能够针对主题进行双向有效的交互，此外，该讨论区的整体网络成员间的联系不紧密，成员参与交互的积极程度不高。笔者建议，要使该讨论获得良好发展，应注重促进讨论区成员间的交互。
