通过小组学习活动加强大规模在线学习课程的潜力尚未得到充分开发。规模和多样性允许优化小组任务中的小组组成。本研究的目的是探讨基于学习者行为而形成的小组如何影响学生在小组任务中的生产力。被分类为高、中、低的学生被随机分配到同质组或异质组。结果表明，总体而言，异质群体要么相似，要么比同质群体更有生产力。然而，我们发现被归类为高水平的同质群体与异质群体一样或更多。然而，异质群体的生产力仍然高于平均同质和低同质群体，这表明异质群体是整个群落的最佳选择。被分类为低水平的学生在同质群体中更有成效，这表明，将不太活跃的学生分组在一起，会使社交懈怠变得更加困难，学生也会更多地参与进来。
There is an underexploited potential in enhancing massive online learning courses through small-group learning activities. Size and diversity allow for optimizing group composition in small-group tasks. The purpose of this paper was to investigate how groups formed based on learner behavior affect productivity of students in a small-group task. Students classified as high, average and low were randomly assigned to homogeneous or heterogeneous groups. Results indicate that overall, heterogeneous groups were either similarly or a bit more productive than homogeneous groups. Yet, we found that homogeneous groups classified as high-level were as or more than heterogeneous groups. However, heterogeneous groups were still more productive than homogeneous-average and homogeneous-low groups suggesting heterogeneous groups are the best choice for the entire community. Students classified as low-level were more productive in homogeneous groups, suggesting that grouping less active students together, makes social loafing more difficult and students participate more.
