在线课程论坛教师互动问题设计的分类及有效性研究

Research on the Classification and Effectiveness of Instructors' Interactive Questions in Online Courses

文章从在线课程论坛教师互动问题设计分类的视角出发,以结构化、聚合性、复杂性和认知水平四个维度为问题分类标准,以131个互动问题设计为研究对象,采用文本分析法对教师互动问题设计进行分类分析,并从学习者参与度和目标达成两个视角对问题有效性进行分析。研究发现,在线课程论坛教师互动问题设计表现出多方向和多维度特征;在问题设计取向上,呈现出结构化、会聚型、简单、低认知水平的特征;不同分类问题未与学习者参与度呈现相关性;教师问题设计有效性整体水平不高,学习者互动参与的量与质较低;目标达成整体水平有待进一步提高。

This research was conducted from the perspective of question classification in online course forum. Four dimensions including structurazation, polymerization, complexity and cognitive level were used as the question classification standards. One hundred and thirty-one discussion questions were regarded as the research object. The classification analysis of discussion questions designed by instructors was conducted with the method of content analysis. Additionally, the effectiveness of different question types was analyzed from two perspectives which included learner engagement and goal attainment. We found that the questions designed by instructors in online forum displayed multi-direction and multi-dimension features. The questions showed characteristics of structured, convergent and simple in the design orientation. There was no correlation between question classification and student’s engagement. The overall effectiveness of designed questions was not high, which in turn leaded to low quality and quantity of interaction. The overall level of goal attainment still needs to be further improved.
