小组工作通常是我们要求学生在积极和互动的环境中学习时如何互动的关键组成部分。这一功能的一个常识性扩展是包括小组评估。此外,关键的科学实践之一是发展合作工作关系。作为教师,我们应该认识到我们的班级在课堂的社会熔炉中的发展,沿着他们认知和/或解决问题技能的发展。我们分析组考试网络数据从两个类的介绍物理序列。在每一堂课上,在四次考试中,学生们参加了一次个人版本的考试,然后和同学们一起修改考试。学生们记录了他们的合作者,这些报告用于构建定向网络。我们比较全球网络的措施和节点中心分布在每学期的考试和对比这些趋势之间的学期。使用位置分析和边缘介数社区检测来划分网络,位置分析通过链接行为的相似性来阻止节点,边缘介数社区检测将密集连接的节点分组。通过计算每个考试的块结构和随时间的映射,可以在两类序列中看到稳定的社会结构。比较全局和节点级别的测量结果表明,从第一次到第二次检查的时间段会破坏网络结构,即使块相对稳定。
Group work is often a critical component of how we ask students to interact while learning in active and interactive environments. A common-sense extension of this feature is the inclusion of group assessments. Moreover, one of the key scientific practices is the development of collaborative working relationships. As instructors, we should be cognizant of our classes’ development in the social crucible of our classroom, along with their development of cognitive and/or problem solving skills. We analyze group exam network data from a two-class introductory physics sequence. In each class, on each of four exams, students took an individual version of the exam and then reworked the exam with classmates. Students recorded their collaborators, and these reports are used to build directed networks. We compare global network measures and node centrality distributions between exams in each semester and contrast these trends between semesters. The networks are partitioned using positional analysis, which blocks nodes by similarities in linking behavior, and by edge betweenness community detection, which groups densely connected nodes. By calculating the block structure for each exam and mapping over time, it is possible to see a stabilizing social structure in the two-class sequence. Comparing global and node-level measures suggests that the period from the first to second exam disrupts network structure, even when the blocks are relatively stable.
