教师引领BBS论坛讨论活动的角色行为评价模型

An Evaluation Framework for Role Performance in Teacher-led BBS Forum

本文在梳理BBS论坛讨论活动相关研究基础上,确立了教师引领BBS论坛讨论活动的角色行为,分为设置讨论主题、澄清讨论问题、提供问题解决策略、监控讨论进程和建构讨论氛围等五个维度,并针对上述五个维度编写了绩效行为评价问卷。经因素分析,问卷具有良好的区分度、信度和结构效度。

This study involved 179 teachers, who are tutors of network-based distance courses, from six learning centers in three cities in Shandong Province, China. A questionnaire survey was administered, covering five dimensions, i.e. raising topics for discussion, clarifying the topics, providing options of approaches to solving problems, monitoring the discussion and creating the discussion atmosphere. Informed by the findings, the paper analyzes the role performance in the tutor-led BBS forum. In addition, a questionnaire was designed to evaluate role performance in relation to the five dimensions. The construct validity of the questionnaire was validated by factor analysis. The study indicates that the teacher's role of leading BBS discussion is essential for students' understanding and interaction. It can be a good starting point for further research in this field.
