在线协作讨论中角色策略的设计与效果探究

A Study on the Design and Effect of Role Strategy in Online Collaborative Discussion

在线协作讨论中,普遍存在学习参与度低等问题,因此角色策略被教师广泛应用于在线教学中。为探究在线协作讨论过程中角色策略的应用情况,比较自由讨论和角色讨论的实际效果,文章分别从学习行为和学习体验两个维度,设计了两轮自由讨论和角色讨论的策略交替进行实验。研究发现,学习者在自由讨论与角色讨论中的行为参与具有显著性差异,学习者对角色讨论具有轻微偏好,扮演不同角色学习者的帖子总字数和归纳总结能力具有显著差异。本研究的结果可以为角色策略在在线协作讨论中的应用指导提供参考依据。

In order to solve the problem of the low participation in online collaborative discussion,role strategy is widely applied by teachers in online teaching.To explore the application of the role strategy in online collaborative discussion and to compare the actual effects of free discussion and role-based discussion,this arti-cle designed an experiment with two rounds of discussion in which free discussion and role-based discussion strategy were carried out alternatively from the perspectives of learning behavior and learning experience respectively.The results showed that there were significant differences in leamers,behavior participation between the two kinds of discussion,learners had slight preference for role-based discussion,and learners with different roles had significant differences in the total number of words and the ability of summarizing.The results of the research provide reference for the application of the role strategy in online collaborative discussion.
