可视化方法在分组讨论教学中的应用

The Application of Visualization Method in Group Discussion Teaching

分组讨论教学方法通过在课堂上设计和执行各种小组学习任务来促进学生协作和沟通技能的发展,促进学生对问题的深入理解。文章设计和实现了一种可视分析系统以支持教师有效评估和提高学生在分组讨论过程中的互动和学习表现。系统提取活跃度、贡献度、协作度、领导力、困惑度等五种重要的学生表现特征,设计了一种新颖的互动关系视图,用于展示和分析学生间互动关系。结合所设计的视图和交互技术,用户可从议题进展、学生互动以及学生表现三种不同角度对分组讨论教学的动态过程进行深入的分析和可视化呈现。

The method of group discussion teaching promotes the development of students'collaboration and communication skills by designing and executing various group learning tasks in the classroom,and promotes students'deep understanding of problems.This paper designs and implements a visual analysis system to support teachers in effectively evaluating and improving students'interaction and learning performance during group discussions.The system designed in this paper extracts five important student performance characteristics,such as activity,contribution,collaboration,leadership,and perplexity,and designs a novel interactive relationship view to display and analyze the interaction between students.By combining the designed view and interaction technology,users can conduct in-depth analysis and visualization of the dynamic process of group discussion teaching from three different perspectives:topic progress,student interaction,and student performance.
