课程BBS讨论的漂移现象与表现特征

Research on Excursion in Course Discussion on BBS

本文在分析课程BBS论坛内容和访谈学习者、指导教师的基础上,描述了BBS讨论活动中未能或难以实现学习目标的四类漂移现象,包括问题讨论缺乏深度、讨论活动偏离主题轨迹、讨论内容有大量冗余信息,以及挑起与主题缺乏相关性的无聊话题等。

BBS is now a commonly used interactive platform for asynchronous interaction in ODE.Owing to the features as an asynchronous interaction tool,it can help distance learners in reflecting and communicating on higher lever.But in fact,there is a big gap between the practical effect and anticipant goal when using BBS for discussion in some courses.The authors first analyze the content of discussion via BBS in course,then interview some learners and instructors that attended discussion,thus sum up four types of excursion effecting the realization of learning targets:a) the discussion is somewhat superficial;b) the focus on the theme always shifted;c) information redundancy exists in discussing content;d) the irrelevant topics are easily aroused.Three measures are put forward aiming at these phenomena:the instructors should recognize their roles and position;the positive circumstances are to be established and cultivated for discussion;the problem-solving training on instructional design is to be reinforced.
